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.
