In industrial production, use the heat generated by fuel combustion, or convert electrical energy into heat energy, so as to purchase thermal equipment for various processing techniques such as smelting, heating, drying, sintering, cracking and distillation of workpieces or materials, Known as industrial furnaces.Vacuum Heat Treatment Applications for Metal Machine Tools and Gear Parts Industrial kiln is mainly composed of furnace lining, furnace frame, heating device (such as combustion device, electric heating element), preheater, furnace front pipeline, smoke exhaust system, furnace machinery and other parts.Pay Attention to Vacuum Tempering to Improve the Quality of Quenched Parts At present, industrial furnaces are widely used in all walks of life in the national economy, such as metallurgy, building materials, chemical industry, light industry, food and ceramics and other industries. It has many varieties, high energy consumption and great influence, and is the key equipment for industrial heating. The development of its heating technology and the adoption of high-efficiency energy-saving technology have a great impact on improving product quality, reducing production costs, rationally utilizing energy, improving working conditions, and realizing civilized production.Analysis of vacuum heat treatment process for wind power products In practical application, according to different industrial furnaces and specific production process requirements, comprehensive consideration should be given to design, construction, operation, maintenance and management, and strive to meet the above basic requirements as much as possible.Vacuum Hardening Stainless Steel
Resistance furnaces are widely used in the national economy, and high-power resistance furnaces are used in various industrial production processes. However, there are various interference factors in most resistance furnaces, Vacuum Heat Treatment of Fasteners which will bring great changes to industrial production. Therefore, in the design of the resistance furnace temperature control system, it is necessary to consider how to effectively avoid various interference factors and adopt a better control scheme.Vacuum sintering of transparent ceramics It is very necessary to choose a suitable chip and control algorithm.

Regenerative combustion technology has been used in large-scale and high-temperature furnaces such as blast furnace hot blast stoves, open hearth furnaces, coke ovens, and glass melting furnaces since the mid-19th century. Optimal Vacuum Heat Treatment For Bevel Gears The principle is to use the waste heat recovery device in the regenerator to alternately switch the flue gas and air to make it flow through the regenerator, so as to recover the sensible heat of the high-temperature flue gas to the greatest extent and increase the temperature of the combustion-supporting air. However, the traditional regenerator uses checker bricks as the regenerator, which has low heat transfer efficiency, large regenerator volume, and long reversing cycle, which limits its application in other industrial furnaces.Vacuum Hardening Stainless Steel The new type of regenerator adopts ceramic balls or honeycomb as the regenerator, and its specific surface area is as high as 200-1000m2/m3, which is dozens to hundreds of times larger than the old checker bricks, thus greatly improving the heat transfer coefficient. The volume of the regenerator can be greatly reduced. In addition, due to the improvement of the reversing device and control technology, the reversing time is greatly shortened. The reversing time of the traditional regenerator is generally 20-30 minutes, while the reversing time of the new regenerator is only 0.5-3 minutes.Sintering of B4C by Pressureless Liquid Phase Sintering The new regenerator has high heat transfer efficiency and short reversing time, resulting in low exhaust gas temperature (below 200°C), and high preheating temperature of the preheated medium (only 100-150°C lower than the furnace temperature). Therefore, the waste heat of the exhaust gas is recovered close to the limit, the temperature efficiency of the regenerator can reach more than 85%, and the heat recovery rate can reach more than 80%.Vacuum Heat Treatment of Fasteners
The feeding gate is a proportional valve, that is, a valve that can control the switching speed of the valve. The proportional valve has a pilot valve, and the pilot valve must be energized whether the valve is opened or closed. The proportional valve is a valve controlled by 4~20mA signal, 4~12mA controls the valve to close, and 12~20mA controls the valve to open.Vacuum Hardening Stainless Steel The absolute value of the difference between the current and 12mA determines the speed of the valve action. The larger the absolute value of the difference, the faster the valve action; the smaller the absolute value of the difference, the slower the valve action.Sintering of B4C by Pressureless Liquid Phase Sintering Unloading gate operation screen: The computer controls the power on and off of the pilot valve and the input current of the proportional valve by comparing the set value of the blanking gate with the actual value of the blanking gate, so as to realize the precise positioning of the blanking gate. That is to say, when the deviation between the set value and the actual value is less than 100 degrees, there is no need to adjust the opening degree, and the unloading gate will not act. When the deviation between the set value and the actual value is greater than degrees, and the set value is greater than the actual value, the valve is opened; when the deviation between the set value and the actual value is greater than degrees, and the set value is less than the actual value, the valve is closed. Vacuum Heat Treatment of Fasteners There are 3 speed gears for forward and reverse valve action, which are high speed, medium speed and low speed respectively. The larger the deviation value is, the faster the valve action speed will be. When the difference between the actual angle and the set angle is greater than 8 degrees, use high speed, when it is 4~8 degrees, use medium speed, and when it is less than 4 degrees, use low speed.Vacuum sintering of transparent ceramics

The performance of metal materials is generally divided into two categories: process performance and service performance. The so-called process performance refers to the performance of metal materials under the specified cold and hot processing conditions during the processing and manufacturing process of mechanical parts. Vacuum Oil Quenching for steel hardening heat treatmentThe quality of the metal material process performance determines its adaptability to processing and forming in the manufacturing process. Due to different processing conditions, Vacuum sintered powder metallurgy partsthe required process performance is also different, such as casting performance, weldability, forgeability, heat treatment performance, machinability, etc. The so-called service performance refers to the performance of metal materials under the conditions of use of mechanical parts, including mechanical properties, physical properties, chemical properties, etc. The performance of metal materials determines its scope of use and service life.Vacuum heat treatment of aluminum alloy die castings In the machinery manufacturing industry, general mechanical parts are used in normal temperature, normal pressure and non-strongly corrosive media, and each mechanical part will bear different loads during use. The ability of metal materials to resist damage under load is called mechanical properties (or called mechanical properties).316L stainless steel vacuum brazing process
Since the birth of precalcining kiln in the early 1970s, it has gone through four stages of development. (1) The first stage. Early to mid 1970s. It is the birth and development stage of pre-decomposition technology.Metallographic Inspection Knowledge of Bolt Quenching And Tempering In 1964, the German Dottenhausen cement plant used oil shale containing combustible components as a component of cement raw materials. In order to avoid premature volatilization of combustible components in the low-temperature part, they fed oil-bearing shale raw meal in the middle of the suspension preheater to increase the decomposition rate of raw meal entering the kiln, creating a precedent for pre-decomposition technology.Ion Nitriding vs Gas Nitriding But the precalciner kiln that really uses advanced fuel as the second heat source in the calciner started in 1971. Therefore, the birth of precalciner kiln should be the first SF kiln (Suspension Preheater-Flash Furnacel) jointly developed by Japan IHI Company and Chichibu Cement Company. Vacuum Heat Treatment of FastenersAfter the birth of the first SF kiln, various types of precalciner kilns appeared one after another in Japan (MFC furnace of Mitsubishi Corporation - 1971; RSP furnace of Onoda Cement Company - 1972; KSV furnace jointly developed by Kawasaki and Ube Cement Company - 1974 year, etc.). All calciners use heavy oil as fuel.Sintering of B4C by Pressureless Liquid Phase Sintering
