vacuum tempering furnace is mainly used for bright tempering of high-speed steel, high-alloy tool steel, electrical magnetic materials, stainless steel and other materials, and can also be returned and re-crystallized with too much non-ferrous metal.
Vacuum tempering furnace structure features:
The heating chamber adopts full metal screen structure, small deformation, small thermal inertia, suitable for low temperature tempering, long life and easy maintenance. The nickel belt heater is used for easy installation and low failure rate. There are movable heat-insulating doors in the front and rear of the furnace. The heating chamber is closed to prevent heat loss. When cooling, it opens to form a high-pressure airflow passage to speed up the cooling. With convection heating device and rapid cooling device, it can be filled with inert gas when heating, and the convection heating device is turned on to achieve uniform convection heating in the low temperature section and improve work efficiency. The rapid cooling system effectively controls the amount of tool deformation and accelerates workpiece cooling. The electronic control system adopts PLC and programmable temperature controller to realize automatic, semi-automatic and manual control modes, and the operation is flexible.
