Pit Furnaces

Home / Our Products / Furnaces / Pit Furnaces

A Pit Furnace is a vertical, cylindrical furnace built into the ground or partially recessed. It's designed for heat treating long, tall, or heavy parts - especially shafts, rods, tubes, and bars - that are loaded vertically. It's most commonly used for annealing, normalizing, carburizing, hardening, and tempering of steel components.

Key Characteristics

Vertical loading (parts are suspended into the furnace)
Often deep and narrow - ideal for long parts
Gas-fired or electric heating
Can operate in air, inert gas, or carburizing atmospheres
Heavy-duty insulation to retain heat

Applications

Shafts, spindles, rods
Gears, bearings, and springs
Oil & gas tool components
Aircraft landing gear
Carburizing or nitriding of steel
Stress relieving of weldments or forgings

Advantages

Great for long vertical parts
Good temperature uniformity
Can be sealed for protective or carburizing atmospheres
Heavy-duty design = long service life
Available in manual or automated configurations
