Automatic control systems are widely used in various fields, especially in industrial fields, and temperature control is one of the most common control types in control systems. With the rapid development of single-chip microcomputer technology, controlling the controlled object through single-chip microcomputer has increasingly become an important development direction in the field of automatic control in the future. This design requires the design of an electric furnace temperature control system with a single-chip microcomputer.Fixture Selection in Vacuum Brazing Furnace The temperature control system is mainly composed of four parts: temperature sensor, temperature regulator, actuator, and controlled object. Its system structure diagram. The controlled object is a large-capacity, large-inertia electric furnace temperature object, which is a typical multi-order volume delay characteristic. In engineering, it is often approximated as a second-order volume delay with pure hysteresis; due to the large capacitance of the controlled object, SCR is usually used as the actuator of the regulator.Effect of Additives on Vacuum Sintering of Ceramics To adjust the temperature of the heating furnace, in the industry, within the set cycle range, the circuit is turned on for several cycles, and then several cycles are turned off, and the ratio of the on-off time of the thyristor in the set cycle is changed to adjust the load. The average voltage of the terminal AC is the load power, which is commonly referred to as a power regulator or a cycle controller;HD SERIES HIGH SPEED CNC DRILLING MACHINE The power regulator triggers the thyristor to turn on when the power supply voltage crosses zero, so what is obtained on the load is a complete sine wave, and what is adjusted is only the voltage cycle that is turned on within the set period Tc. Assuming that the wave number of the conduction cycle in the cycle Tc is n, and the cycle of each cycle is T, then the output power of the power regulator is P=n×T×Pn/Tc, and Pn is when the voltage in the set cycle Tc is fully passed The output power of the device.SMART HIGH PRECISION VERTICAL DRILLING MACHINE

Most of the boilers needed by industrial and mining enterprises in production are steam boilers. Steam is mostly used in production where a certain temperature of heat is required to meet the requirements of the production process, such as textile printing and dyeing, food sugar, rubber paper, petrochemical and other industries. Therefore, it is necessary to determine the saturated steam parameters of the boiler in accordance with the requirements of the production process. The advantage of saturated steam is that it can ensure a constant temperature required for production.CNC HORIZONTAL LATHE Generally, the pressure of the boiler is always higher than the saturated steam pressure required for production, the reason is to overcome the pressure loss in the pipeline or pipe network. At present, in many cases, the boiler nameplate pressure is much greater than the pressure required for production. For example, many users have purchased a 13-pressure boiler, but actually only use the operating pressure of 5 gauge or 6 gauge. Running at such a low pressure has adverse effects on steam quality. Because the pressure decreases, the specific volume of the steam increases, and the flow rate at the outlet increases greatly, so that the phenomenon of steam carrying water increases. Generally, the pressure required for actual production plus the pressure drop required to overcome all pipeline resistance plus 25% to 30% of the pressure margin is enough.LARGE CNC HORIZONTAL LATHE The head of the feedwater pump is matched with the nameplate of the boiler. The actual operating pressure of the boiler is too low, and the power consumption of the feedwater pump is obviously a huge waste.Core Hardness Control of Carburized Gears The boiler steam parameters used in small power plants can be configured according to the parameters required by the steam turbine. Most of them use superheated steam at 25 gauge atmospheric pressure. If the turbine is superheated steam with 13 gauge atmospheric pressure, then the boiler should choose the superheated steam parameters with 16 gauge atmospheric pressure, which can make the steam quality better.Vacuum sintering of Al2O3 ceramic products

Boiler tubes are a type of seamless tubes. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements on the steel type used in the manufacture of the steel pipe. According to the use temperature, it is divided into two types: general boiler tube and high pressure boiler tube.Research on Vacuum Brazing Technology of Ceramic and Metal High-pressure boiler tubes are often under high temperature and high pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durable strength, high resistance to oxidation and corrosion, and good structural stability.Influence of Vacuum Carburizing and Quenching on New Gears use: ①General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc.HIGH-EFFICIENCY FAST WIRE CUTTING EDM MACHINE ②High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.ZNC EDM HOLE DRILLING MACHINE

A device that uses the heat energy released by fuel combustion or other heat energy to heat water or other working fluids to produce steam, hot water or other working fluids with specified parameters (temperature, pressure) and quality.Influence of Vacuum Carburizing and Quenching on New Gears Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. Aircraft engine rectifier vacuum brazing The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator.X6132 X6140 HORIZONTAL LIFTING TABLE MILLING MACHINE Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to as boilers for short, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.X6230 SERIES UNIVERSAL SWIVEL HEAD MILLING MACHINE

As thermal equipment for smelting, roasting, sintering, melting, heating and other processes of materials or workpieces, relatively complete copper smelting furnaces have appeared in China as early as the Shang Dynasty in industrial furnaces, and the furnace temperature can reach 1200 °C. During the Spring and Autumn Period, with the development of technology to increase furnace temperature, cast iron appeared at that time.Aircraft engine rectifier vacuum brazing In 1794, a straight cupola for melting cast iron appeared in the world. Then, in 1864, on the basis of Siemens (England) regenerative furnace principle, Martin (France) built the first steelmaking open hearth furnace heated by gas fuel. Through the high temperature preheating of air and gas in the regenerator, he made the furnace temperature reach the temperature above 1600 ℃ required for steelmaking.Heat treatment process of gear vacuum carburizing and quenching By the 1920s, the supply of electric energy was gradually sufficient, and various resistance furnaces, electric arc furnaces and cored induction furnaces were used in industry to achieve a wide range of applications. At the same time, the emergence of mechanized and automated furnace types has increased furnace productivity and improved working conditions to a certain extent.HORIZONTAL MITRE BAND SAW MACHINE BS-650G In the 1950s, coreless induction furnaces developed rapidly. Later, electron beam furnaces appeared, which use electron beams to impact solid fuels, which can enhance surface heating and melt materials with high melting points.HORIZONTAL MITRE BAND SAW MACHINE BS-712N

The stage from the fuel into the furnace to the ignition temperature is called the preparation stage. In this stage, the evaporation of water should be completed, the volatile matter should be separated out, and the mixture of fuel and air should reach the ignition temperature. Obviously, this stage is the endothermic process, and the source of heat is flame radiation and high-temperature flue gas backflow. In addition to the burner itself, the factors that affect the length of the preparation stage are the strength of the heat provided by the hot flue gas in the furnace for the pulverized coal flow, the amount, temperature, concentration, volatile content and fineness of the pulverized coal flow.Aircraft engine rectifier vacuum brazing When the ignition temperature is reached, the volatile matter is first ignited and burned, releasing heat to increase the temperature, and the coke is heated to a higher temperature and begins to burn. The combustion stage is a strong exothermic process, the temperature rises rapidly, and the chemical reaction is strong. At this time, the surface of the carbon particles often appears in an oxygen-deficient state. The key to the enhanced combustion stage is to strengthen the mixing, so that the air flow is strongly disturbed, so as to provide oxygen to the surface of the carbon particles, and diffuse the carbon dioxide on the surface of the carbon particles.CVD Diamond Tool Brazing The burnout stage is mainly to burn off the unburned carbon in the combustion stage. Although there is not much carbon left in the burnout stage, it is very difficult to completely burn it out. The main reason is that there are many factors that are not conducive to complete combustion, such as a small amount of carbon. The fixed carbon is surrounded by ash; the oxygen concentration is already low; the disturbance of the air flow is gradually attenuating; the temperature in the furnace is gradually decreasing.CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-280II If the fuel has low volatile content, high ash content, coarse pulverized coal, and small furnace volume, it will be more difficult to completely burn out. According to the test, for coal powder with a fineness of R90=5%, 97% of the combustibles can be burned in 25% of the time, while the remaining 3% of the combustibles can be burned in 75% of the time. This is the basic reason why it is impossible to completely burn the combustibles in the actual boiler.CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-380

CVD Diamond Tool Brazing The forced convection leveling tempering unit adopts a unique injection flow increasing technology. By sucking hot air in the furnace and mixing it with preheated compressed air in the nozzle, the temperature of the airflow ejected from the nozzle to the glass surface is greatly increased, and the hot air in the furnace is circulated by convection.

Steel for high-strength bolts The chemical composition requirements of steel for high-strength bolts are as follows: Carbon is the most important element affecting the plastic deformation of steel. The higher the carbon content, the higher the strength of the steel and the lower the plasticity. The higher the carbon content, the lower the quenching heating temperature, the higher the hardenability, and the higher the tendency of cracking and deformation. Manganese can reduce the harmfulness of sulfur to steel.Vacuum pressureless sintering of boron carbide ceramics with additives As a permanent element in steel, the increase of manganese can increase the tensile strength and yield strength of steel, and increase the hardenability. Among the alloy steels, CrMo and CrMoV are more suitable for high-strength fasteners used under complex conditions.Vacuum Sintering of Quartz Ceramics In order to control the bolt strength and guaranteed stress within the qualified range, on the basis of increasing the lower limit of hardness, the following five aspects should be paid more attention to during tempering. Differences in materials, furnace types, upsetting (differences between red punching and cold heading), thread differences (difference between full teeth and half teeth, the total effective cross-sectional area of full teeth is small.SGL COLUMN MOVING SURFACE GRINDING MACHINE The bearing tensile strength is low, the tempering temperature deviation is 5-10°C and the difference between the medium (the difference between water quenching and oil quenching). 3. Operation points of mesh belt furnace High-strength fasteners have large production volume and low price, and the threaded part is relatively fine and precise. Therefore, mesh belt furnace is especially suitable for heat treatment of small and medium-sized fasteners, with high degree of automation and good heat treatment quality. .SGT COLUMN MOVING SURFACE GRINDER FOR RAIL GRINDING

Gas-fired hot water boiler refers to a boiler that uses flammable gases such as natural gas and liquefied petroleum gas as fuel, and automatically supplies hot water to meet people's daily needs such as heating and bathing. With the awareness of environmental protection and energy saving and emission reduction in the whole society, the energy structure of boilers and heating systems has also shown corresponding changes.Vacuum pressureless sintering of boron carbide ceramics with additives Gas-fired hot water boilers have received widespread attention due to their energy-saving, environmental protection, safety and automatic operation characteristics. At present, they have gradually replaced traditional coal-fired boilers and become the main heating method in cities. How to effectively use energy-saving technology to reduce the operating cost of the boiler, further save limited resources, and prolong its service life as much as possible under the premise of safe operation has become an important issue for the staff.Aircraft engine rectifier vacuum brazing Generally speaking, there are many types of gas-fired hot water boilers, such as heating type and bathing type according to usage; normal pressure type and pressure type according to structure; vertical type and horizontal type according to structure, etc. Although various types of gas-fired hot water boilers have certain differences in their structures and shapes, their working principles and operating modes are generally the same, so their energy-saving technologies are relatively universal.Z3132 RADIAL DRILLING MACHINE Since gas has the characteristic of burning more fully than solid and liquid, gas-fired hot water boilers are more efficient than coal-fired boilers. High combustion thermal efficiency. The survey also shows that, compared with coal-fired boilers, the promotion and use of gas-fired hot water boilers has improved the heating season in various places.Z3040X13 RADIAL DRILLING MACHINE

The reasonable selection of the furnace bottom strength of the regenerative heating furnace is closely related to the furnace length, actual heating capacity, heating quality, and furnace operating conditions (combustion load, furnace pressure, maintenance cycle, furnace body life, etc.). However, there is no detailed information on the calculation of the bottom strength of the regenerative heating furnace. Through the selection and calculation of the furnace bottom strength in the medium-plate regenerative heating furnace project of a steel plant, it is ensured that the use effect is basically consistent with the actual capacity of the furnace.Aircraft engine rectifier vacuum brazing (1) The selection of the furnace bottom strength of the regenerative slab continuous heating furnace. When the billet is a room temperature billet and the thickness of the raw material is 150-300mm, it should be based on the heat penetration time of the billet. The furnace bottom strength is generally 600-700kg ( m2.h) is more suitable.Large complex mold vacuum heat treatment process (2) When continuous hot charging, the heat storage continuous heating furnace can calculate the heating capacity according to experience. Taking the normal temperature billet as the benchmark, the heating capacity will increase by 11% to 12% for every increase in the billet. Calculating its thermal charging capacity, the furnace bottom strength is more suitable at 1050-1150kg（m2.h）.HD2020-1 CNC SINGLE- SPINDLE GANTRY MOVABLE HIGH-SPEED DRILLING MACHINE (3) Because the average radiation temperature and pressure of the regenerative continuous heating furnace is much higher than that of the traditional continuous heating furnace, under the same conditions, the thermal charging heating capacity can be increased by 45% to 55% compared with the traditional furnace.HD2016S HIGH SPEED CNC DRILLING MACHINE

There are two types of suspension preheaters: cyclone preheater and vertical cylinder preheater. In the preheater, due to the contact surface between the raw material and the gas.Large volume and good heat exchange, so the thermal efficiency of the system is much higher than other kiln types.Vacuum brazing process of honeycomb materials The exhaust gas discharged from the main combustion zone enters the four-stage or five-stage cyclone after complete combustion in the subsequent combustion zone. The preheated raw meal enters the fuel decomposition and combustion zone of the D-D furnace from the three-stage or four-stage cyclone, and enters the kiln through the five-stage cyclone after preheating and decomposition.High Temperature Vacuum Brazing of Niobium Alloy and Stainless Steel The D-D furnace throat directly connected to the kiln tail is a device for adjusting balance, which can balance the combustion gas volume of the rotary kiln and the high-temperature air passing through the tertiary air duct. At the same time, since the raw meal fed to the D-D furnace forms a eruption layer in the reduction zone, the concentration of the raw meal in the lower part of the D-D furnace increases, so that the temperature of the exhaust gas entering the furnace drops sharply, preventing the bottom of the furnace from forming a crust .C6180A UNIVERSAL LATHE The technological process in charge of the calciner is mainly the decomposition process of carbonate. In the actual production process, there are many factors affecting the decomposition of raw meal carbonate, and the situation is also very complicated.

The focus pusher is made of Q345-B material, with water cooling wall; it is made of 16Mo3 material, without water cooling wall. Since the coke pusher is the core component of the coke pusher equipment and even the entire coke oven machinery, if the design structure of the coke pusher is unreasonable or the material is improperly selected, the entire coke discharge process will be affected. Therefore, it is very important to choose the structure and material of the focus pusher reasonably. The design structure, material and advantages and disadvantages of the two focus pusher rods are introduced below.NdFeB magnet vacuum sintering process The design concept of Yankuang 7.63m coke oven machinery is environmental protection, structural optimization and energy saving.
