In this paper, it is described the cleanness of liquid steel is improved by studying and optimizing the technologies of each working procedure for steel making; in the vacuum degassing treatment with RH furnace, the yield of rare earth in products could reach 50% by further come-up of inclusions in the circulation of liquid steel and adding rare earth element in late stage of vacuum treatment; the effects of adding rare earth element to decrease Nb content and the original chemical composition without rare earth element on product performances are studied.

通过对炼钢各工序工艺研究,优化炼钢工艺,提高了钢水的洁净度;RH炉真空脱气处理,通过钢水循环夹杂物的进一步上浮,真空处理后期加入稀土元素,产品稀土收得率达到50%;研究添加稀土元素降低铌含量与原成分未添加稀土元素对产品性能的影响。

In this paper, it is described the cleanness of liquid steel is improved by studying and optimizing the technologies of each working procedure for steel making; in the vacuum degassing treatment with RH furnace, the yield of rare earth in products could reach 50% by further come-up of inclusions in the circulation of liquid steel and adding rare earth element in late stage of vacuum treatment; the effects of adding rare earth element to decrease Nb content and the original chemical composition without rare earth element on product performances are studied.
