Product Description

Vertical Pit Type Industrial Heat Treatment Furnace

Process Control in Gas Carburizing

Precision control ensures consistent case depth and hardness. Key factors:

A. Carbon Potential (CP) Control

Definition: The ability of the furnace atmosphere to transfer carbon to the steel.
Control Methods:
- Oxygen Probes – Measure O₂ to estimate carbon potential.
- Infrared (IR) Analyzers – Monitor CO₂ and CH₄ levels.
- Dew Point Sensors – Measure moisture in the furnace.

B. Temperature & Time

Typical Range: 870–950°C (1600–1740°F)
Diffusion Time:
- Shallow Case (0.1–0.5 mm): 1–4 hours
- Deep Case (1–3 mm): 8–24 hours

C. Gas Composition

Common Gases:
- Natural gas (CH₄), Propane (C₃H₈), Endothermic gas (Rx gas: 20% CO, 40% H₂, 0% CH₄)
- Diluent Gases: Nitrogen (N₂) to control carbon potential.
