Large Pit Furnace and Deep Pit Furnace

Equipment Application

Large Pit Furnace and Deep Pit Furnace are generally used for heat treatment of large-diameter workpieces, annular Large workpieces, and are suitable for annealing, Quenching , Tempering heat treatment of super-long and special-length rod and shaft workpieces. Workpieces placed vertically or hung have small deformation.

This series Large Equipment can be applied to High Temperature medium temperature Low Temperature operation, and can be used for heat treatment processes such as annealing, Quenching , Tempering for metal materials and mechanical parts such as Alloy Steel , high chromium steel, high manganese steel. Large Pit Furnace can have a diameter of up to 6 Meter , and the depth of deep pit furnaces can reach 27 Meter .

Structural Features

Large Pit Furnace and Deep Pit Furnace are built by Full-Fiber High Pressure module masonry Furnace Lining for heat preservation . Because this series of Equipment has very large specifications and dimensions in both depth and diameter directions , in order to ensure uniform temperature at all points in the working area inside Furnace Chamber , especially to reduce temperature difference in the vertical depth direction , heating elements are specially designed for this type of Pit Furnace . It not only adopts multi - segment partition settings from top to bottom , but also each segment adopts microcomputer program High Precision independent control , Furnace Lining heat preservation Energy Saving , with small empty furnace loss , saving electricity and reducing consumption .
