Description
The vacuum oil quenching furnace is suitable for vacuum oil quenching of materials like alloy steel, bearing steel, spring steel, die steel, high-speed steel, etc. Horizontal twin chamber oil quenching furnace can also applied to aging and gas cooling process for the above materials.
Technical Features
1. Excellent temperature uniformity realized by octagon-shaped furnace hearth.
2. The heating elements adopt unique non-ceramic supporting technology. It can be used for five years without any insulation problem.
3. The inner trolley is overlap type stretchable structure with frequency converting function. It has a stable transportation speed with "full-fast-slow” steps, which makes the transportation time very short.
4. Build-in heat exchanger and forced gas cooling type contribute to the uniformed and high-low-rating jet gas, which eventually makes the cooling speed very fast.
5. Auto load cart, remote control, loading and unloading need only one operator.
6. High volume oil tank and hot oil cooling by external circulation and heat exchanger, achieving has a better cooling effect.
7. Two cooling types -- oil stirring and oil injection cooling, are used for various kinds of products, which makes the product have less deformation.
8. The horizontal twin chamber heat treatment furnace features larger load capacity and higher efficiency comparing with other same specification products.
Optional Configuration of Vacuum Oil Quenching Furnace
1. Furnace door: On-line/off-line, vertical up and down, rotating
