摘要
对45号优质圆钢卡爪热处理断裂情况进行了分析,并从淬火介质、冷却速度、化学成分、淬火温度、裂纹形态和尺寸等方面进一步分析了产生断裂的原因及预防措施。
The fracture condition of 45 high quality round steel jackcatch under heat treatment was analyed. The reason and preventive measures of producing fracture was given from quenching media, cooling speed, chemical composition, quenching temperature, fracturing shape to size of jackcatch.
