摘　　要：针对鞍钢股份有限公司炼钢总厂二分厂高碳硬线钢铸坯废品率高的问题,采用六西格玛管理的方法分析了工艺技术、设备和基础管理几方面存在的问题,通过控制中间包钢水过热度、二冷水比水量、稳定拉速并控制电磁搅拌频率和电流,高碳硬线钢铸坯的废品率降至0.12%以下。Considering the problem on the high scrap rate of billets for hard wire steel rodswith high carbon in No.2 Branch of General Steelmaking Plant of Angang Steel Co., Ltd., the sixsigmamanagement system was used to analyze the problems existing in the fields of the processengineering, equipment management and basic management. After taking such measures as controllingthe degree of superheat of molten steel in tundish and the specific water flow of secondarycooling water, stabilizing the casting speed and controlling the electromagnetic stirring frequencyand current, the scrap rate of billets for hard wire steel rods with high carbon was reducedup to 0.1 2 %.
