Vacuum High Pressure Gas Quenching Furnace

Vacuum high-pressure gas quenching furnace is generally a single chamber furnace structure, there are vertical and horizontal types of furnace. Vacuum high-pressure gas quenching furnace is suitable for the vacuum gas quenching treatment of tool steel, die steel, high-speed steel, stainless steel and other materials; Solid solution treatment of stainless steel pipe fittings and other materials; Annealing treatment of various magnetic materials; It can also be used for vacuum brazing and vacuum sintering of stainless steel.

The purpose of quenching is to convert supercooled austenite to martensite or bainite, get martensite or bainite structure, and then with tempering at different temperatures, to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of steel, so as to meet the different requirements of various mechanical parts and tools. It can also meet the special physical and chemical properties of some special steels such as ferromagnetism and corrosion resistance by quenching.

Our vacuum high-pressure gas quenching furnace has the following advantages.

① Convection heating is adopted to achieve rapid and uniform heating in the low temperature section.

② Adopt the method of automatically controlling the partial pressure of the protective gas in the furnace to prevent the volatilization of elements at high temperatures.

③ Using large diameter ring copper pipe to make the radiator, cooling speed is fast.

④ The air nozzles are uniformly placed  360 degrees uniform and staggered along the circumference of the heating chamber, the cooling uniformity is good, and the workpiece deformation is small.

⑤ The heating element is evenly arranged 360 degrees along the circumference of the heating chamber, with high temperature uniformity, low power loss and high energy saving.

⑥ The use of new composite hard felt or metal screen for heating insulation layer, high temperature, high pressure, anti-airflow erosion, insulation screen life extension.

⑦ Programming process flexible input, stable and reliable mechanical action, perfect safety system and abnormal warning system, so that the equipment has high reliability and easy maintenance.

Vacuum high-pressure gas quenching furnace is mainly composed of vacuum furnace body, vacuum system, air cooling system, water cooling system, inflation system, control system, etc. 

Vacuum high-pressure gas quenching furnace is a relatively ideal heat treatment equipment for the surface treatment of parts, especially for the materials of some special parts of military technology and microelectronics technology, which need to be vacuum quenched to meet the requirements. Compared with ordinary quenching, vacuum quenching has many advantages, such as uniform quenching, small deformation, no damage to the surface, no oxidation, greatly improving production efficiency and reducing production costs.
