摘要
本文阐述了昆钢采用转炉连铸工艺开发60si：Mn、55CrMnA、50CrVA、SUP9四个牌号，轧制K75—130mm、厚11—28mm范围近30个规格的平面弹簧扁钢的试制情况；并针对轧制出现的典型质量问题进行专项分析，提出了工艺控制改进措施。
Adopted converter-continuous casting process, four trademarks were developed at Kungang,such as 60Si2Mn, 55CrMnA, 50CrVA and SUP9. The trail production of nearly 30 specifications of planar spring flat steel was presented, which the breadth varied from 75 to 130 mm, the thickness varied from 11 to 28 ram. The typical quality problems occured during the rolling were analyzed. Finally, the improvement measures were put forward.
