| Abstract: | The thermomechanical Spheroidizing annealing technology of GCr15 bearing race is investigated in this paper. The effect of different technology parameters on spheroidzation are discussed.The rmplts denote that satisfactory microstructure and hardness for macnining can be acquired bysuitable thermomechanical spheroidizing annealing technology. Comparing with conventionalspheroidizing annealing technology, the thermomechanical sphetoidizing annealing technology notonly considerably shorts the holding time of annealing but makes carbide particles finer and their distribution more uniform. It is an advanced process for producing medium and small bearing raceblanks. |
