| Abstract: | After pre-heat-treatment process, the grain-size of the dies of Cold Rotary Forging can be effectively controlled, and the distribution of corbide can be well improved. The pre-heat-treatment process gets the structure ready for the last-heat-treatment, gets the high strength and toughness of the dies, and is benefical to the service life of the dies of Cold Rotary Forging. |
