Vacuum Carburizing Furnace for High-Precision Surface Carburizing Treatment

A vacuum carburizing furnace is advanced low-pressure high-speed surface strengthening heat treatment equipment, which completes carburizing infiltration treatment on the surface of low-carbon steel and alloy steel workpieces in a closed low-pressure vacuum environment. Traditional atmospheric carburizing has the disadvantages of slow infiltration speed, long production cycle, uneven carburized layer, large workpiece deformation and easy surface oxidation and decarburization. Vacuum carburizing technology perfectly solves these industry pain points, realizing high-efficiency, high-precision and low-defect carburizing processing.

The vacuum carburizing furnace adopts pulse-type carburizing gas supply and precise carbon potential control system, which can accurately control carburizing depth, infiltration speed and surface carbon concentration according to workpiece material and process requirements. The low-pressure vacuum environment accelerates the diffusion speed of carbon atoms, greatly shortens the production cycle, and makes the carburized layer uniform and dense with stable thickness. At the same time, the vacuum environment completely avoids surface oxidation, decarburization and blackening defects, and the workpiece deformation rate is extremely low, which does not affect the subsequent precision size processing.

This equipment is widely used for high-precision processing of automotive gears, transmission shafts, engine parts, mechanical precision bearings and aerospace structural components. It can significantly improve the surface hardness, wear resistance, contact fatigue resistance and service life of workpieces, while maintaining the excellent toughness and impact resistance of the core material. As high-end upgrading equipment for modern precision heat treatment, vacuum carburizing furnaces help manufacturing enterprises improve product grade and market competitiveness.
