| 摘 要： | 使用有害元素含量极低的铁水以转炉+LF炉+RH+CC+800/650轧机的工艺生产高等级轴承钢。因采用了连铸全程保护浇注、结晶器电磁搅拌、气雾冷却和末端轻压下等技术,所以生产出的连铸坯的成分和组织均匀,并且减少了偏析和裂纹倾向。通过在转炉中加入铬铁吹炼去除合金中的钛,并且钢水中氮含量很低,最大程度降低了钛的危害。所生产轴承钢达到瑞典的SKF标准。

| Abstract: | High grade bearing steel was produced from molten iron with extremely low content of hazard elements through a complex process which consists of a converter,LF,RH,CC and 800/650 mm rolling mill. By adopting technologies such as shielded casting in the whole continuou casting process,mould electrical-magnetic stirring,mist cooling and soft reduction at the end point,etc.,the composition and structure of CC billets was uniform,and segregation and cracking tendency were reduced. By adding ferrochrome into the ... |
