摘要

对轴承钢的冷装和热装加热进行实验室热模拟

对不同热装温度加热后的铸坯晶粒度级别进行分析

对比冷装条件下晶粒度

找到合理的热装温度。试验结果表明

当热装温度超过700℃

其铸坯组织的晶粒和冷装相比明显变得粗大

晶粒度级别在1～2级;根据生产现场连铸坯相变前的平均冷却速度为0.41℃/s

GCr15轴承钢连铸坯的热装温度应控制在670℃以下。

Abstract

For bearing steel in the cold and hot charging heating for laboratory thermal simulation

analyzed the level of casting billet grain size of hot charging by different heating temperature

and compared the grain size under the condition of cold charging

find the reasonable hot charging heating temperature. The results show that： when the hot charging temperature over 700℃

compared with cold charging

its casting billet organization of grain become bulky

grain size level between grade 1 ~ 2； According to the work site

the before phase change cooling rate of casting billet as an average of 0.41 ℃/s

the hot charging temperature of GCrl5 bearing steel casting billet should be controlled less than 670 ℃.
