🧩 Product Overview
The Low Pressure Vacuum Carburizing Oil Quenching Furnace is an advanced vacuum heat treatment system that integrates carburizing and oil quenching processes in a single unit.
This system enables:
- Low pressure vacuum carburizing (LPC)
- High-speed oil quenching
- Fully automated heat treatment cycles
👉 Designed for high-performance steel components requiring:
- High surface hardness
- Excellent wear resistance
- Minimal distortion
Low-pressure carburizing ensures precise carbon control, uniform case depth, and improved fatigue life.
⚙️ Core Applications
This furnace is widely used in:
- Automotive gear and transmission components
- Bearings and shafts
- Tool steels and die steels
- Aerospace structural parts
Suitable materials include:
- Alloy structural steel
- Bearing steel
- Spring steel
- High-speed steel
- Stainless steel
👉 Especially effective for:
- Complex geometries (blind holes, narrow slots)
🔬 Working Principle (LPC + Oil Quenching Process)
The system combines low-pressure carburizing and oil quenching in a controlled vacuum environment:
- Evacuate chamber to high vacuum
- Introduce hydrocarbon gas (acetylene/propane)
- Perform carburizing through gas diffusion
- Transfer workpiece to oil quenching chamber
- Rapid cooling in quenching oil
👉 Result:
- Uniform carburized layer
- No oxidation or decarburization
- High hardness with strong core toughness
Low-pressure carburizing operates under low-pressure hydrocarbon decomposition, ensuring excellent reproducibility and process control.
