cold rectifying; cold reducing; cold reduction; cold-roll; cold-rolling; cold-rolling reduction; cold rolling (【技】冷轧以热轧的半成品或成品为原料,在低于再结晶温度的条件下进行的轧制。通过冷轧可以生产表面光洁、尺寸精确、力学性能好的钢材。还能生产薄、小轧件。: ① The advantage of hot rolling is that it can be reduced in thickness much more easily. But the surface finish and accuracy are not so good as those obtainable by cold rolling. 热轧的优点是轧件减薄十分容易,但轧件表面精整度和精度不如冷轧好。 ②The power required for cold rolling is greater than that for hot and the requirements of accuracy and surface finish are more precise. 冷轧需要的功率大于热轧,其轧制精度和表面精整度要求更为精确。) |
