Low pressure vacuum carburizing furnace can form a surface free of oxides and pollutants, and combine carburizing and gas quenching to improve the deformation behavior of parts, increase carburizing temperature, reduce intermittent treatment time, greatly reduce gas and energy consumption, and prevent the generation of carbon black. Low pressure vacuum carburizing furnace can greatly reduce production cost and improve equipment utilization rate, and the pressure is very low, so the cost of using atmosphere is significantly reduced. In addition, due to the characteristics of low pressure carburizing equipment and process, high temperature carburizing can be carried out, so properly increasing the carburizing temperature can greatly shorten the carburizing time.

The control system of the low pressure vacuum carburizing furnace can precisely control the carburizing process, so the processed workpiece has good repeatability, and the workpiece deformation is small, the surface is bright, and there is no need to carry out mechanical processing after carburizing. It has greater flexibility. Its equipment can be used as independent equipment, or it can be connected with cold processing to form a production line. The equipment itself can be cyclical and suitable for small batch and multi variety production.
