热滚动钢和冷滚动钢之间的区别

滚动过程是不同的，但是构图可以相同。具有相同的钢号，热滚动通常更柔软。高精度纸通常是通过冷滚动产生的。汽车行业和家用电器使用许多冷钢钢。

冷卷钢通常分为普通等级（C<0.12%), low carbon grade (C<0.10%) and ultra-low carbon grade (C<0.08%), and the lower the carbon content, the better the cold plasticity, which is widely used in the electronic industry. The thickness of the sheet is generally less than 3mm, and it is difficult for the cold-rolled steel to be cold processed if it is thicker. Due to the different production and processing technology, hot rolled steel sheet has good cold plasticity, good stamping formability and small friction damage to the mold. Therefore, in industrial applications, hot rolled steel plate can be generally thicker than cold rolled steel plate

通常，必须将冷滚动钢（例如镀锌和彩色的钢板）退火，因此可塑性和伸长率也更好，该钢材也可以广泛用于汽车，家用电器，硬件和其他行业。通常，热卷纸的表面表面表面无法满足要求，因此需要冷滚动钢条。更重要的是，热滚动钢条的厚度通常为1。0 mm，冷滚动钢条的厚度可以到达0。1mm。在专业上，热滚动在结晶温度点以上滚动，冷滚动在结晶温度点以下滚动。
