摘　　要：从应力角度分析了加工车间H13钢锭生产过程各主要工序可能产生裂纹的成因 ,在此基础上改进了均热工艺 ,并提出了轧制、缓冷及修磨等工序降低裂纹废品的具体措施。实践证明 。From the stress point of view, the reasons for cracking in various production stages was analyzed, according to which the soaking process was improved, and the concrete measures to decrease crack reject during rolling, slowly cooling and grinding was suggested. Production process showed that the improved process was feasible.
