摘要: 研究了60%~80%冷轧压下率对3.5 mm CSP热轧板轧制的1.4~0.7 mm冷轧深冲带钢力学性能、组织和织构的影响。结果表明,随冷轧压下率由60%提高至80%,冷轧带钢的再结晶开始温度由560℃降至520℃,成品带钢组织细化;当冷轧压下率为74.3%时,成品DQ级带钢的深冲性能最佳。随冷轧压下率提高,成品深冲带钢△r值逐渐减小,这与成品带钢中{112}〈110〉织构取向函数值f(g)升高有关。

Abstract: Effect of 60% - 80% cold reduction on structure, texture and mechanical properties of 1. 4 ~0. 7 mm cold rolled deep-drawing strip steel from 3. 5 mm CSP (Compact Strip Production) hot rolled plate has been studied. Results show that with increasing cold reduction to 80% from 60% , the beginning recrystallization temperature of cold rolled strip steel decreases to 520 °C from 560 Y and the structure of strip steel products fines, and with 74. 3% cold reduction the DQ lever deep-drawing performance is optimum. With increasing cold reduction the △r value of deep-drawing strip steel products gradually decreases, that is relating to enhancement of orientation function f/(g) value of {112}〈110〉 texture in strip steel products.
