The pit-type furnace is a vertical cylindrical heat-treatment device with workpieces hung or stacked and heated in a sealed well chamber. It enables diverse heat treatments: annealing, spheroidizing annealing, quenching, tempering, normalizing, nitriding, carburizing and carbonitriding. Its design ensures uniform temperature distribution, making it ideal for processing long, shaft-like, or large components. It is widely applied in batch heat treatment of workpieces that require consistent heating effects and minimal deformation during processing. We are a professional pit type furnace manufacturer in China.

Pit-type furnaces are extensively used in heavy-duty manufacturing industries. They are core equipment in automotive for axle and crankshaft processing, and in aerospace for landing gear and turbine shaft heat treatment. They also serve metallurgical forging, construction machinery, shipbuilding, and wind power equipment sectors. Additionally, they are applied in tool and die manufacturing and military hardware production, adapting to the processing demands of large-sized and high-precision components.
