冷滚和热滚

冷滚动和热滚动之差主要是滚动过程温度高温常态 热温高

从线程学的角度来看,冷滚动和热滚动的边界应分辨为累进式温度即慢速冷滚温度比慢速热温度高钢硬化温度450~600摄氏度

热滚动和冷滚动的主要差别如下:

开工外观和表面质量:
Because of cold plate is, resulting from the hot plate in cold rolling process and cold rolling at the same time also can do some surface finishing so cold plate on the surface quality (such as surface roughness, etc.) better heat plate, so if the product after the sequence on the quality of paint coating, such as there are higher requirements, generally choose the cold plate, hot plate, pickling board and other pickling plate, pickling board surface as the pickling too so into normal metal color, but remained in the high cold plate, cold rolled so surface without pickling plate surface oxide layer, usually hair black, or ferroferric oxide layer.常用语句中,它像火, 如果存储环境不好,它通常有一点点生锈

二叉性能:总体热板和管道工程机械特性不再思考,尽管冷滚动过程有某些工作加固热管道(但不排除机械性能严格性能,这需要区别)、冷板热板通常略高产量强度、表面硬性更高、什么具体需要看到冷板退火程度退火冷板比热板强

3级热冷板性能基本差不太多,因此成形因素取决于表面质量差,而表质量优则实验研究,用同素钢板冷热板效果更好
