What is a Pit Type Furnace?

A Pit Type Furnace is a vertical furnace installed below ground level (in a pit), designed to heat long or heavy components uniformly. It is especially suitable for processing shafts, rods, pipes, and cylindrical components that require vertical positioning during heat treatment.

Working Concept of Pit Type Furnaces

Pit Type Furnaces operate by placing materials inside a vertical chamber where heat is generated through electric elements or fuel burners. The design ensures:

• Uniform heat distribution from all sides
• Reduced heat loss due to enclosed structure
• Efficient processing of long components
