Application:
Mainly used for quenching of high-speed steel, tool and die steel, stainless steel; solution treatment of stainless steel and titanium alloy; magnetic vacuum heat treatment, high temperature brazing and vacuum sintering of flexible materials, and low temperature tempering can be performed by adding a convection fan.


Structural features
1. The heating chamber adopts stainless steel skeleton and new carbon felt composite material, which has less deformation and is resistant to high temperature and high pressure airflow.
2. Long service life and easy maintenance. Using graphite tube heater, easy installation and maintenance, low failure rate.
3. The air cooling adopts the jet cooling method, and the graphite nozzles are evenly distributed around the circumference, which makes the high-pressure air flow more reasonable (the air volume of some main air ducts can be adjusted, and the customer can control the air volume of some main air ducts according to the characteristics of the workpiece), which can effectively control workpiece
deformed.
4. High-speed, high-pressure and large-flow fans, copper-copper high-efficiency circular heat exchangers, to achieve high-speed cooling. fan available
Use variable frequency speed regulation to control the air cooling speed.
5. The heating chamber can also adopt an all-metal structure to meet the solid solution treatment requirements of titanium alloys and precision alloys.
The electronic control system adopts PLC and programmable temperature controller to realize three control modes: automatic, semi-automatic and manual, and the operation is flexible.
