摘要
采用转炉-精炼-连铸-型材轧机工艺流程试制60CrMnA弹簧扁钢。通过采取拉碳法、LF精炼及喂丝、保护浇铸和轧制合理控制冷却等措施,解决了生产中存在的扁钢硬度高、表面毛刺、侧面裂纹等问题,生产出了符合GB1222-84标准和满足用户要求的60CrMnA优质弹簧扁钢。
Introduces the trial production of 60CrMnA spring flats： LD converter-refining-continuous casting-sectian rolling processes are adopted. Many effective measures such as catch carbon method, LF refining, wire feeding, protective casting and reasonable control cool system, etc. have adopted, solving the quality problems of the flat bars such as high hardness, surface barbs and cracks in the side, producing 60CrMnA high quality spring flats which conform to the standard of GB 1222-84 and meet requirements of customers.
