Vacuum furnace

---

Appear before and after vacuum furnace in the 1930 s, in the midst of all walks of life to get extensive application gradually, and promote the speed is very fast, because really give us industrial production has brought the huge advantage and convenience, can be applied to various industries of processing and production of vacuum heat treatment, so it was widely applicable industry, use simple structure is also quite convenient, can reduce the working process of the loss of time.

Vacuum furnace is generally composed of furnace body, furnace chamber, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and so on. The sealed furnace case is welded with carbon steel or stainless steel and the joint face of the removable parts is sealed with vacuum sealing material. In order to prevent the deformation of the shell after heating and the deterioration of the sealing material, the shell is generally cooled by water or air cooling. The furnace chamber is located in the sealed furnace shell. According to the purpose of the furnace, the furnace chamber is equipped with different types of heating elements, such as resistance wire, silicon carbon rod, silicon molybdenum rod, induction coil, electrode and electron gun. A crucible is installed in the vacuum furnace for smelting metal, and some are equipped with automatic pouring device and manipulator for loading and unloading materials. The vacuum system mainly consists of vacuum pump, vacuum valve and vacuum gauge.

Mainly used for: cold and hot mold steel, high speed steel, elastic alloy, high temperature alloy, stainless steel, titanium alloy, magnetic material and other materials vacuum heat treatment.

Vacuum quenching :(tempering, annealing) is a process whereby materials or parts are heated and cooled in a vacuum state according to process procedures to achieve the desired properties.

Vacuum brazing: A welding process in which a set of welding parts is heated to above the melting point temperature of the filler metal, but below the melting point temperature of the matrix metal, and a weld is formed by the wetting and flow of the filler metal to the matrix metal (the brazing temperature varies with different materials).

Vacuum sintering is a process in which metal powder products are heated in the vacuum state so that adjacent metal powder grains are sintered into parts by adhesion and diffusion.
Vacuum magnetizing: it is mainly used for magnetizing metal materials.

Vacuum furnace can completely eliminate surface during heating process to produce some of the impurities, so you can get products without metamorphic layer clean surface, can make the product surface bright clean, so in the use of modern industry is very broad, almost in the production of heat treatment process of the industry, are all need to use such industrial equipment for processing and processing, can achieve better results.

Key advantage is the use of the vacuum furnace is safe, and for the environment without any pollution, in the process of use will not discharge any waste gas waste water, so for the atmospheric environment is a very good protection effect, also accord with our country industrialization of green environmental protection requirements of the modern society, both can be carried out within the fastest speed processing production, improve work efficiency, also can guarantee for environmental pollution treatment, do not need to undertake “three wastes” treatment, solve the pressure of the air pollution.

And relatively high mechanical and electrical integration of vacuum furnace, the temperature control is accurate, so the increase in accuracy, on the basis of the movement of the workpiece and the adjustment of air pressure can be programmed in advance, when the program is written, you can enter to the implementation of the work, carried out in accordance with the steps of programming implementation, all working system can be in accordance with the requirements for work, to avoid human resource waste.

Moreover, the high working efficiency of vacuum furnace can save working resources to the greatest extent and avoid excessive consumption and waste of energy. The high concentration of electric heating energy can make heating more efficient, and the effect of energy saving can be said to be quite significant. Therefore, it absolutely reaches the highest standard requirements in terms of energy saving and environmental protection.

Unique advantages of vacuum furnace in use:

Vacuum furnace with electric heating element, in the process of production, can be the most close to the vacuum state, heated in vacuum environment, can let the furnace chamber portion of the material discharge, can let the furnace chamber pressure is less than the standard air pressure, such ability can let the realization of the internal space state real vacuum, and the use of the whole work process, does give us the actual advantages into full play.

Vacuum furnace can very quickly improve the work efficiency, and the temperature control system of the operation is simple, vacuum system and the protection of the power supply system is also very strong, so I can ensure the safety of using overall and vacuum system can ensure good sealing, nature will make the vacuum performance is stronger, in the process of operation, can improve the work efficiency to the greatest extent, to avoid the loss and waste of resources.

I believe you now for the unique advantages of vacuum furnace has the comprehensive understanding, in the process of use, these advantages can play a maximum guarantee processing production advantage, can avoid the staff 24-hour guard, reduce the labor intensity of the workers, and in the process of computer system use, can also be very easy for the corresponding intelligent control, to ensure production stability.
