| Abstract: | Considering the problem on the high scrap rate of billets for hard wire steel rods with high carbon in No.2 Branch of General Steelmaking Plant of Angang Steel Co., Ltd., the six-sigma management system was used to analyze the problems existing in the fields of the process engineering, equipment management and basic management. After taking such measures as contro-lling the degree of superheat of molten steel in tundish and the specific water flow of secondary cooling water, stabilizing the casting speed and controlling the electromagnetic stirring frequency and current, the scrap rate of billets for hard wire steel rods with high carbon was reduced up to 0.12%. |
