Answer:
hot-rolled steel plate is heated to a certain temperature, and then rolled into a sheet. Easy rolling, rolling, high efficiency, hot-rolled sheet in itself is quite soft and easy-to post-processing, but it is precisely because of soft and easily deformed.

cold-rolled plate is at room temperature, not to the steel heating, directly into a plate mill, due to the cold steel rather hard, rolling up more strenuous, cold-rolled sheet itself is relatively hard, stiff and smooth, post-processing after the deformation is not easy .

Answer:
hot-rolled steel plate is in the red-hot rolled under the state, the dimensional accuracy is poor, uneven thickness, but the prices are low, the surface oxide layer. Generally do not have packaging, there is no thin size.
cold-rolled plate is at room temperature after repeated rolling of steel, smooth surface, size and high precision thickness is very uniform, soft and easy to stretch, can be deep processing. A box packaging and packaging sheet, minimum thickness of 0.15 millimeters.

回答:
热轧板是把钢铁加热到一定温度，然后轧制成板材。轧制容易，轧制效率高，热轧板材本身比较软，易于后期加工，但是正因为软，也容易变形。

冷轧板是在常温下，不将钢铁加热，直接用轧机轧制成板材，由于冷的钢铁比较硬，轧制起来比较费劲，冷轧板本身比较硬，挺括，后期加工之后不易变形。

回答:
热轧板就是钢板在红热的状态下进行轧制的，尺寸精度差，厚薄不均匀，但是价格低廉，表面有氧化层。一般没有包装，没有很薄的尺寸。
冷轧板是在常温下经过反复轧制的钢板，表面光洁，尺寸精度高，厚薄非常均匀，柔软易拉伸，可以进行深加工。有盒子包装和卷材的包装，{zd1}有0.15毫米厚度。
