Effects of rolling processes on textures of wires for tire cord steel

摘要: 采用X射线衍射法对国内外四家钢厂帘线钢盘条的织构进行了对比研究.结果表明,国内外各钢厂盘条的织构存在明显差异,国内盘条轴向上的111织构强度大于国外盘条,然而盘条轴向上的111织构是硬取向,不利于盘条的拉拔.通过延长加热炉加热时间、提高加热温度和提高吐丝温度,可以使111织构的强度明显降低.Abstract: XRD analysis was used to compare the textures of tire cord steel produced from four different steel works at home and abroad.The results show that the textures of wire rods produced at domestic and foreign works are obviously different.The strength of 111 texture in the axis of wire rods produced at domestic works is stronger than that at foreign works,however 111 texture in the axis of wire rods has strong orientation,which is adverse to wire drawing.The strength of 111 texture can be obviously decreased by prolonging the heating time of heating furnaces and increasing the heating and laying temperature.
