摘要
用六西格玛方法,对影响管线钢生产的全线流程进行分析,找到了影响夹杂物重要因素并进行初步改善;对渣碱度与合格率进行了双比率假设检验,结果表明:渣碱度与夹杂物金相一次检验合格率存在较强相关性。
the article analyses the whole production line process of pipeline steel with six sigma method, find important factors of influence inclusion and to make a primary improvement. Furthermore, the article conducts a double ratio hypothesis analysis of slag basicity and soundness. The results showed that there is a strong correlation between slag basicity and single metallographic examination soundness of inclusion.
