🧩 Product Overview
The Vertical Vacuum Gas Quenching Furnace is a high-performance vacuum heat treatment system designed for precision quenching of large and complex components with minimal deformation.
Unlike horizontal furnaces, the vertical structure provides:
- Uniform load distribution
- Reduced deformation of long or heavy parts
- Better vertical airflow cooling efficiency
This system is widely used for high-end metal heat treatment under vacuum and high-pressure gas quenching conditions.
⚙️ Core Applications
This vertical vacuum gas quenching furnace is ideal for:
- Tool steel and die steel heat treatment
- High-speed steel (HSS)
- Bearing steel and alloy steel
- Aerospace structural components
Especially suitable for:
- Long shaft parts
- Heavy cylindrical components
- Thin-walled parts prone to deformation
👉 Vertical furnaces are preferred for large-size and deformation-sensitive parts
🔬 Working Principle (Vacuum + Gas Quenching)
The furnace integrates vacuum heating and high-pressure gas cooling:
- Load materials into vertical chamber
- Evacuate to high vacuum level
- Heat materials to target temperature
- Introduce high-pressure inert gas (N₂ / Ar)
- Perform rapid gas quenching
👉 Result:
- Bright surface (no oxidation)
- Uniform hardness
- Minimal deformation
