Horizontal Single Chamber Vacuum High Pressure Gas Quenching Furnace

Description
High pressure gas quenching furnace applied for gas quenching of materials like tool steel, die steel, high speed steel, etc. It has no special dimension and shape requires for the components. The components features little deformation and good cooling effect.

Technical Features
1. The furnace is horizontal, single chamber, bottom loading structure. Furnace door open type can be customized design.
2. Excellent temperature uniformity realized by octagon-shaped furnace hearth.
3. For different cooling speed requirements, it can use single heat exchanger furnace hearth cooling or dual and multi-stage heat exchanger furnace hearth cooling.
4. For different components, horizontal single chamber gas quenching furnace is optional to use backside gas inlet quenching circulation system or front side gas inlet quenching circulation system.
5. Unique two-stage heat exchanger is adopted, so the heat exchange area is twice than before.
