Horizontal Twin Chamber Vacuum High Pressure Gas Quenching Furnace

Description
Horizontal gas quenching furnace is used for gas quenching of materials like tool steel, die steel, high speed steel, super high strength steel, etc. The heating chamber is separated with the quenching chamber, which saves much energy and has good cooling.

Technical Features
1. Vacuum twin chamber gas quenching furnace uses horizontal, two chambers, bottom loading structure. Furnace door type can be customized design.
2. Gas quenching chamber is an independent part, which has a high heat exchanging speed.
3. The inner loading trolley is integral structure. The materials transportation is stable and finish in a short time.
4. According to the treating jobs, users can choose to configure axial-flow type high power gas quenching fan or centrifugal high power gas quenching fan.
