摘　　要：对安阳钢铁集团有限责任公司钢帘线用LX70盘条的研制与开发过程、帘线钢冶炼连铸工艺和轧制工艺、帘线钢中夹杂物的控制及钢帘线应用情况等进行了研究和分析。结果表明:帘线钢中夹杂物的控制、良好的铸坯凝固组织、高比率的索氏体金相组织是保证高质量帘线钢盘条的重要因素;LX70盘条拉拔性能优良稳定,捻制过程满足子午线轮胎用钢帘线合股要求,总满轮率达到国内同类型产品先进水平,完全满足钢帘线用户的使用要求。The research and development process of wire rod for steel cord,the refining-continuous casting process and strip rolling process of steel cord,the control of the inclusions and the trial-manufacture situation in steel in particular of Anyang Iron and Steel Group Co.,Ltd.were introduced.Trail-manufacture result illustrates： inclusions control in steel cord,well strand solidification structure,high ratio sorbitic metallographic structure are key factors of high quality rod for steel cord.The drawing performance of LX70 of Angang is well and stable,twisting process satisfies meridian tyre for steel cord stranding requirement,the total full round of rate reaches advanced level of domestic products with the same type,completely satisfies the use requirement of the user of steel cord.
