Pit Type & Well Type Furnaces: Precision Heat Treatment Solutions
Advanced vertical furnace solutions engineered for efficient heat treatment of large, long, and specially shaped components across aerospace, automotive, and heavy machinery industries.
About Pit Type & Well Type Furnaces
What Are Pit Type Furnaces?
Pit type furnaces, also known as well type furnaces, are vertical heat treatment furnaces designed with a deep chamber that extends below floor level. This unique design allows for convenient top-loading of long, heavy, or irregularly shaped components using overhead cranes.
The vertical orientation ensures excellent temperature uniformity throughout the working volume, making them ideal for heat treating shafts, tubes, bars, and other elongated components.
Key Applications
- Quenching: Rapid cooling for hardening steel components
- Tempering: Stress relief and toughness enhancement
- Annealing: Material softening and stress relief
- Carburizing: Surface hardening through carbon diffusion
