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

摘要: 采用X射線衍射法對國內外四家鋼廠簾線鋼盤條的織構進行了對比研究.結果表明,國內外各鋼廠盤條的織構存在明顯差異,國內盤條軸向上的{111}織構強度大于國外盤條,然而盤條軸向上的{111}織構是硬取向,不利于盤條的拉拔.通過延長加熱爐加熱時間、提高加熱溫度和提高吐絲溫度,可以使{111}織構的強度明顯降低.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.
