稀土轴承钢制轧机轴承寿命的研究

Study on the Service Life of the Rolling Mill Bearing of Rare-Earth Bearing steel

介绍了加入微量稀土的GCr17SiMn(RE)新轴承钢及其在轧机轴承制造中的应用研究。轴承的性能优良、使用寿命长、轧钢生产稳定、经济效益明显。

This paper deals with that a new bearing steel(GCr17SiMnRE)has been developed,and the application of this steel for making the roll millbearing was studied.The result shows that this bearing has better properties,longer service life and so the rolling mill production is stable leading anotable economic benefit.
