Usage  

The vacuum high pressure gas quenching furnace is a very advanced vacuum heat treatment equipment, which has splendid performance and special design. It is suitable to be used for high-speed steel, molding tool steel, stainless steel, alloy steel, titanium alloy  and other alloy material high precise components’ vacuum gas bright quenching and annealing, the magnetic material’s sintering and fast cooling and so on.

The radiator is made of large aperture annular copper tube, cooling fast.

The tuyere is laid surrounding the heating chamber evenly and interlaced. The cooling uniformity is good and the workpiece deformation is small. The heating element is laid surrounding the heating chamber evenly. The temperature uniformity is high, the power loss is low and the energy saving is high.

Using a new type of composite hard felt / meltal as the heating type heat-insulation course. It has the features of high temperature and high pressure resistance, high gas velocity resistance and its service life is long.

Flexible programming technique input, stable and reliable mechanical action, and perfect security system and abnormal warning system, make the equipment have high reliability and maintainability.

The complete standard modularization design includes the steel structure furnace shell body, the compound heat preservation screen of the heating zone, the heating tape (stick), the high-velocity air flue, the high efficiency motor with fan, the high efficiency gas heat interchanger, the hot gasification system, the vacuum system, the cooling aqueous system and the electricity control system.

The maximum inflation pressure is 1.0Mpa （absolute pressure）, and the inflation pressure is adjustable continuously from 0.2 MPa to 1.0 Mpa, and it has two kinds, the graphite internal furnace and metal internal furnace, and the graphite heating element and molybdenum belt heating element.
