High speed and economic vacuum carburizing process:


    The low-pressure vacuum carburizing (LPC) technology extends to higher carburizing temperature and wider steel materials for low pressure carburizing. It is a modern, rapid economical low - pressure carburizing replacement technology, and makes low - pressure carburizing process more widely.


Low pressure carburizing technology:


     The characteristic of low pressure carburizing is that the transmission coefficient of carbon is very high. In the initial stages of carburizing, for example, in 950 ℃ temperature (1740 ° F), reach the surface of carbon atmosphere of 250 g/a m2h. This means that the low pressure carburizing is faster than the atmosphere when it is needed.


     And the traditional carburizing process in the thick layer of this advantage is much smaller. For example, in the case of 0.8mm (.00315 inches), carbon transfer is more dependent on the diffusion coefficient (DC). Low - pressure carburizing process can be easily carried out in general vacuum furnace. General vacuum furnace temperature can reach 950-980 ° C (1700-1800 ° F) compared with the traditional atmosphere carburizing process of 880-930 ° C (1600-1700 ° F). Due to the higher carburizing temperature increased the diffusion coefficient (DC) to shorten the carburizing cycle. Compared with the traditional atmosphere carburizing process, the carbon content in the carburizing atmosphere and the faster diffusion coefficient (DC) are also the reasons for the improvement of vacuum carburizing efficiency.
