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 of LX70 wire rod for steel cord of Anyang Iron and Steel Group Co., Ltd., the process of steel smelting and continuous casting of cord steel, the rolling process, the control of inclusions in cord steel and the application of steel cord are studied And analysis. The results show that the control of inclusions in cord steel, the good slab solidification microstructure and the high ratio of sorbite microstructure are the important factors to ensure high quality cord steel wire rod. The drawing performance of LX70 wire rod is excellent and stable, The twisting process meets the requirements of the joint of steel cord for radial tire. The total filling rate reaches the advanced level of the same kind of products in China, fully meeting the requirements of users of steel cord.
