This series of equipment is mainly used for heat treatment of gyro materials in high vacuum atmosphere. It is a kind of equipment with high precision, high stability, high reliability and long-time continuous work. At the same time, it is also suitable for bright annealing of silicon steel sheet, soft magnetic material, copper alloy and other materials; bright tempering after quenching of high speed steel, die steel, tool steel, alloy steel and titanium alloy; elimination of residual internal stress after quenching of forgings, welding parts, cold stamping parts and workpieces to prevent deformation and cracking of workpieces, which can be widely used in heat treatment of various devices in production enterprises.
