Tool steel vacuum carburizing furnace

Vacuum carburizing is to put the workpiece into the vacuum furnace, vacuum and heating, so that the furnace is purified, after carburizing temperature into hydrocarbons (such as propane) for carburizing, after a certain period of time to cut off the carburizing agent, then vacuum or nitrogen gas diffusion, and carburizing, diffusion cycle operation. By means of pulse vacuum carburizing, uniform carburizing layer can be obtained for blind holes and small holes. Vacuum carburizing can realize high temperature rapid carburizing (1050 C), greatly shorten carburizing time and improve production efficiency. The permeation layer of the same furnace workpiece is uniform, there is no internal oxidation and no fatigue source in the permeation layer, which greatly improves the service life of the parts.
