The characteristics of low pressure vacuum carburizing

Low pressure vacuum carburizing, can greatly reduce the production cost and increase equipment utilization rate. This is because the low pressure vacuum carburizing atmosphere is very simple, strong permeability period only acetylene or propane, diffusion period only nitrogen gas, and pressure is very low, so the cost of using atmosphere significantly reduced. In addition, due to the low pressure carburizing and the characteristics of the equipment and process, can be high temperature carburizing, so increasing the carburizing temperature, can greatly shorten the carburizing time.
Because of the low pressure vacuum carburizing to carburizing process control system can accurately control, so the processed workpiece has good repeatability, and the workpiece deformation is small, the surface light, without mechanical processing of the reentry after carburizing.
Low pressure vacuum carburizing technology has greater flexibility, the equipment can be used as a stand-alone equipment, can also with cold working together as a production line. The device itself can be either cycle type, suitable for small batch and many varieties of production situation. Can also be a continuous type carburizing by multiple heating chamber, gas quenching chamber, oil quenching chamber, in and out of the chamber, vacuum system, workpiece automatic transportation system, etc, suitable for mass production. In addition, the furnace, the furnace is very simple, only 0.5 h to enter each furnace blow-in operating state.
Low pressure vacuum carburizing using cold wall vacuum technology, no ignition and no fire danger, no pollution, clean, safe, equipment operation is simple, easy to maintenance.
