Vacuum gas quenching furnace heat treatment technology

The working principle of the vacuum gas quenching furnace is to use high temperature heating and gas cooling in a vacuum environment to change the organizational structure and performance of the material. SIMUWU can provide customers with vacuum gas quenching furnace heat treatment technology services to improve the product performance of metal product parts and components, thereby meeting the different use requirements of various parts and tools.

What is a vacuum gas quenching furnace?
A vacuum gas quenching furnace refers to a heat treatment process in which titanium alloys, high-temperature alloys, tool steels, high-speed steels and other materials are loaded into a vacuum furnace, heated to a certain temperature after the furnace reaches the specified vacuum degree of the process, and then quickly filled with high-pressure inert gas to quickly cool the material.

Characteristics of vacuum gas quenching furnace
1. Good air tightness, ensuring that the workpiece will not be oxidized during quenching under high vacuum conditions.
2. Good quenching uniformity and small deformation of the workpiece.
3. Fast cooling speed, which can achieve the requirements of rapid cooling in a short time.
4. No environmental pollution, achieving environmentally friendly production.
5. Low energy consumption. The use of heat-insulating materials and barrier layers can highly concentrate the electric heat energy in the heating chamber to achieve energy-saving effects.

Technical parameters of vacuum gas quenching furnace
1. The heating chamber of the vacuum gas quenching furnace adopts a molybdenum foil furnace. Molybdenum, as a high-melting-point, high-purity material, has good stability and fast heating speed. Molybdenum materials have excellent chemical stability and corrosion resistance. There is no volatilization during the heating process, which reduces the impact of impurities on the workpiece.
2. The ultimate vacuum degree of the equipment is 1×10-4pa. Under low-pressure conditions, the heat conduction and oxidation reaction of the gas can be reduced, thereby protecting the heat treatment effect of the material.
3. The maximum operating temperature can reach 1600℃, which can achieve heat treatment of most metals.
4. The size of the furnace chamber temperature zone: 700mm*500mm*500mm, with a large effective working area, can handle medium and large parts.
5. The gas quenching medium can be argon gas, which can achieve rapid cooling in the furnace chamber and improve the organizational structure of the material. It can also be carried out according to material requirements. The material can only be subjected to furnace cooling heat treatment.
