Products Description

The high vacuum tempering furnace is mainly used for vacuum quenching of tool steel, die steel, high-speed steel, ultra-high strength steel, titanium alloy and other materials, vacuum tempering after solution treatment, recrystallization annealing and vacuum aging of non-ferrous metals.

Vacuum tempering furnace Standard Features

● Single chamber, internally heated, can be made into a horizontal structure.

● Realize high vacuum degree to ensure the tempering quality of the workpiece.

● Optimized furnace liner structure and equipped with convection heating device to ensure uniformity of low temperature;

● Equipped with pressurized air cooling function, it can effectively prevent the occurrence of tempering brittleness;

● The touch screen interface is friendly and practical, which can display and monitor the operating status of devices. It can call, edit, and store the process program library, and has the functions of displaying, querying, and printing process reports, real-time curves, historical curves, and fault alarm reports.
