Vacuum Furnace for Oil and Gas Quenching (Three-Chamber, Two-Chamber)

I. Structural Composition

• Two-chamber vacuum furnace for oil and gas quenching: Mainly composed of a heating chamber, a cooling chamber, an insulating door, an air-cooling fan, and an oil sump. Workpieces are transferred between the heating chamber and the cooling chamber by an internal furnace cart to complete the entire heat treatment process.
• Three-chamber vacuum furnace for oil and gas quenching: Based on the two-chamber furnace, an additional preparation chamber is added. It consists of a heating chamber, a cooling chamber, a preparation chamber, an air-cooling fan, two insulating doors, and an oil sump.

II. Working Principle

• Two-chamber vacuum furnace for oil and gas quenching: Workpieces are first heated to a specified temperature in the heating chamber, then quickly transferred to the cooling chamber by the internal furnace cart, and undergo oil quenching or gas quenching according to process requirements.
• Three-chamber vacuum furnace for oil and gas quenching: Workpieces first enter the preparation chamber for preheating or pre-oxidation treatment, then move to the heating chamber for heating, and finally enter the cooling chamber for oil quenching or gas quenching.

III. Applications

1. Used in industries such as heat treatment, machinery manufacturing, and aerospace.
