冷轧，是用热轧钢卷为原料，在此基础上加工轧制出来的，尽管加工过程中轧制会使钢板升温，但也需要通过连续冷变，形成在力学性能比较差， 硬度太高的轧硬卷。再经过退火工艺，即缓慢加热到一定温度，保持足够时间，然后以适宜速度冷却。恢复其力学性能来达到强度提高， 细化晶粒，调整组织，消除组织缺陷等目的。 Cold rolling, is with hot rolled steel roll as raw material, on this basis of rolling, although the processing process will heat up the steel plate, but also need to be through continuous cold change, formed in the rolling of poor mechanical performance, too high hardness.After the annealing process, that is, slowly heated to a certain temperature, maintain enough time, and then cool at the appropriate speed.Recovery its mechanical properties to achieve strength improvement, refine grain, adjust tissue and eliminate tissue defects.
