摘要
特殊钢厂采用EAF—LF—CC工艺路线研制，通过制定合理技术措施，严格控制钢终点碳、预脱氧，调整精烁炉渣、连铸保护浇注等措施，一次成功开发了J55级油井管用37Mn5钢。
The Special Steel Plant successfully developed 37Mn steel for Class J55 oil well pipes on its＇first test , by adopting the measures such as the use of EAR - LF - CC process flow to set down reasonable technical measures, strictly controlling aim carbon content, preliminary elimination of oxygen, adjustment of refining slag and protective casting.
