Application:
Mainly used for vacuum heat treatment, vacuum welding and vacuum sintering of high-speed steel, hot and cold working die steel, stainless steel, elastic alloy, high-humidity alloy, magnetic material and titanium alloy.
Technical Features:
1. The heating chamber is made of stainless steel frame, and the heat shield is made of multi-layer graphite felt, which has a long service life and is easy to maintain.
2. The graphite tube heater is used, which is easy to install and maintain, so the rate is low.
3. The air-cooling system consists of a high-power high-speed motor, a high-pressure impeller with a large air volume, a volute and a deflector, a copper tube and copper string heat exchanger and a diversion device, etc.
4. The high-speed circulation of the heater enables the workpiece to be cooled quickly and evenly, and the heating chamber can also adopt an all-metal structure.
5. 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.
