Abstract: The  wire  for  steel  cord  of  tyre  is  a  high  carbon   steel(0.70~0.75C-0.15～0.30Si-0.40～0.60Mn), which is widely applied to auto tyre and conveyer belt industries because the rubber products stengthened with 40.15~ 0.38 mm steel cord has excellent strength and springiness which is available to increase the safety of car and decrease fuel expenses. Due to requirement of high quality on wire for steel cord of tyre, in general the process flow sheet :converter or  arc furnace- LF- VD or RH-Ca treatment- concasting is adopted to produce the steel.The control of chemical compositions,  gas content and inclusion is presented and the general conditions of production,quality requirement and development trend of  wire for steel cord of tyre at home and abroad are summarized in this paper.

摘要： 钢帘线钢是成分(%)为0.70~0.75C-0.15~0.30Si-0.40~0.60Mn的高碳钢,由于以Φ0.15~0.38mm的钢帘线作为增强材料的橡胶制品具有优良的强度和弹性,有助于提高汽车的安全性和降低燃料费用,故广泛应用于汽车轮胎及传输皮带等工业领域。钢帘线钢的质量要求高,通常采用的工艺流程为转炉或电弧炉-LF-VD或RH-钙处理-连铸。叙述了钢帘线钢的化学成分、气体含量和夹杂物控制,介绍了国内外钢帘线钢的生产概况、质量要求和发展趋势。
