稀土在钢中应用和研究动向

STUDY AND APPLICATION OF RARE EARTH TO STEEL

综述了目前我国稀土在钢中加入方法和稀土添加剂的应用;稀土在钢中的机理研究;稀土处理钢的连铸结晶器保护渣的研制、稀土铝合金镀液热浸镀钢材表面抗高温氧化性能的研究。这些课题大都转入工业试制或生产,机理研究亦有所突破。

This paper summarizes the method of adding rare earth to steel in our country at present time, the application of the rare earth additives and the mechanismic study on the rare earth in steel. The slags put into the mould is also developed herein. This paper also describes the study on the performance of the surface of the rare earth aluminium alloy hot dipped steel against oxidation at high temperature. These subjects are all put into industry trial-manufacture or production. The mechanism research has been also developed.
