                           VTF446 vacuum tempering furnace


Mainly used for tool steel, die steel, high-speed steel, high strength steel, titanium and other materials after vacuum quenching vacuum tempering (vacuum aging). The purpose of vacuum tempering is to maintain the advantages of vacuum quenching of the material (the product is not oxidized, not decarburization, no carbon, bright surface, non-corrosive pollution, etc.)

Equipment technical characteristics:

1. The furnace is a horizontal single-chamber horizontal charge structure, can also be designed as a vertical vacuum furnace;

2. High-temperature molybdenum heating zone or isostatic graphite heating, molybdenum and aluminum silicate insulation fiber mat insulation, good temperature uniformity;

3. The furnace is equipped with temperature, pressure, water pressure, vacuum and other interlocking features, with a high degree of safety protection and prevention functions;

4. With remote control operation, remote fault diagnosis and remote program updates and other functions;

Optional configuration:

1. Furnace: all-carbon steel/ inner stainless steel / all stainless steel;

2. Vacuum pump: foreign brands / Chinese brands;

3. Operation panel: touch screen / industrial computer;

4. Temperature controller: SHIMADEN / EUROTHERM;

5. Insulation: All molybdenum / molybdenum plus stainless steel / composite carbon felt plus soft mat;
