The two common types of vacuum quenching furnaces are vacuum gas quenching furnaces and vacuum oil quenching furnaces, with some key differences between them:
| Vacuum Gas Quenching Furnace | Vacuum Oil Quenching Furnace | |
|---|---|---|
| Cooling Medium | Uses gas (usually nitrogen or argon) as the cooling medium. The cooling process is gentler and more suitable for workpieces sensitive to deformation. | Utilizes special quenching oil for rapid cooling, ideal for workpieces requiring high hardness and wear resistance. |
| Cooling Rate | Relatively slower cooling rate, mainly used for materials sensitive to temperature changes or requiring toughness. | The involvement of quenching oil, achieves faster cooling rates, enhancing workpiece hardness. |
| Material Applicability | Suitable for various materials, including high-alloy and low-alloy steels, especially for workpieces with high oxidation requirements. | Particularly suitable for high-carbon steels and alloy steels, achieving higher strength and toughness. |
| Cost and Operation | Often simpler in structure, lower operating costs, and easier maintenance. | Equipment is relatively complex, requiring more costs and operational management for oil maintenance and replacement. |
