摘　　要：石钢公司为了进一步调整产品结构,提升产品档次,满足顾客使用,开展了降低GCr15轴承钢碳化物带状组织级别试验。根据试验结果,轧钢加热温度控制在1 240℃,加热3.0～4.5 h比较合理,低温轧制对改善碳化物带状有一定效果。The test to reduce the level of banded structure of carbide in GCrl5 bearing steel is done in Shi Steel to further adjust product structure, enhance the grades of product and meet the requirements of custom ers. It is showed from the test that it is reasonable to control heating temperature in steel rolling at 1240℃, and heating time 3.0 to 4.5 hours, and low temperature rolling has relative effect to improve banded struc ture of carbide.
