【Abstract】 Based on the traditional theory of carbon transfer and diffusion insteel, we pose out a new carburizing process-circling change tempeature accele-rating carburizing process, and it’s correctness and feasibility are proved by both theory and experiment. In research, a carburizing mathematical model considering surface shape of workpieces is used so that calculating results are closer to the practical processes. The author also found a certain relationship between temperature and some factors affecting carburizing rate. And a diagram showing the relationship is drawn in this paper.更多还原
