🧩 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:

  1. Evacuate chamber to high vacuum
  2. Introduce hydrocarbon gas (acetylene/propane)
  3. Perform carburizing through gas diffusion
  4. Transfer workpiece to oil quenching chamber
  5. 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.
