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.
