                       VAF8870 vacuum annealing furnace


Annealing furnace is to change the crystal structure of metal materials and workpieces, refine the structure, eliminate stress and soften the material, meanwhile

Empty annealing can prevent oxidation decarburization, degreasing degreasing, oxide evaporation, in order to improve the surface brightness and mechanical properties of the workpiece. Main application areas: annealing and outgassing of active and refractory metals; electrical steel and electromagnetic alloy, stainless steel and heat-resistant

Annealing of gold, copper and their alloys and steel materials.

Equipment technical characteristics:

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