It is suitable for quenching treatment of die steel, high speed steel, stainless steel and other materials; solid solution treatment of stainless steel, titanium and titanium alloy; annealing treatment and tempering treatment of various magnetic materials; can also be used for vacuum brazing and vacuum sintering, etc.
characteristic：
1. The cooling rate is increased by 100%and the stability is high.
2. The air cooling mode is adopted alternately up and down, the flow rate is uniform and the deformation of workpiece is small.
3. The heating element is evenly arranged around the heating chamber with high temperature uniformity. Hot stirring can be used for vacuum tempering.
4. The composite hard felt / metal screen is used as the heat insulation layer of the heating chamber, which saves 30% energy compared with the air duct structure.
5. Workpiece deformation is small, production efficiency is high, the cost is lowered by 40%.
6. Flexible input of programming process, stable and reliable mechanical action, automatic alarm / display of fault
7. Frequency conversion drive of gas quenching fan, optional convective heating function, optional nine point temperature measurement, classification and austempering.
8. Fully intelligent chemical industry computer control system and a manual operating system.
9. Simple operation, flexible input of programming process, stable and reliable mechanical action.
10. Manual / semi-automatic / automatic fault automatic alarm / display.
