Vacuum carburizing furnace is an improved gas carburizing process. The carburizing pressure is much lower than atmospheric pressure. The typical pressure range is 300-2500pa. The process features are as follows
(1) The steel surface is kept very clean, because there is no gas interaction, carbon reaches the steel surface faster in vacuum.
(2) Carburizing can be carried out at high temperature, so properly increasing the carburizing temperature can greatly shorten the carburizing time.
(3) Because the control system of low-pressure vacuum carburizing can accurately control the carburizing process, the processed workpiece has good repeatability, small deformation and bright surface, so there is no need to carry out machining after carburizing.
(4) Vacuum carburizing technology has more flexibility, its equipment can be used as independent equipment, or connected with cold working into a production line. The equipment itself can be periodic, suitable for small batch, multi variety production. It can also be a continuous type, which is composed of several heating carburizing chambers, gas quenching chamber, oil quenching chamber, inlet and outlet chamber, vacuum system, workpiece automatic transportation system, etc. it is suitable for mass production. In addition, it is very simple to start and shut down the furnace. It only takes 0.5h for each furnace to start to work.
(5) Vacuum carburizing furnace adopts cold wall vacuum technology, no ignition device, no fire risk, no pollution, clean, safe, simple operation and easy maintenance.
