在开始轧制之前，由高压水除鳞装置利用高压水对坯料表面的氧化铁皮进行清理，以避免轧制过程中氧化铁皮的压入，从而保证终产品质量。

Before starting rolling, the high pressure water descaling device is used to clean the scale of billet surface by high pressure water, so as to ***oid the indentation of oxide scale during rolling process, so as to ensure the final product quality.

钢的轧制，是整个轧钢生产过程的核心。坯料通过轧制完成变形过程。轧制工序对产品质量起着决定性作用。轧制产品的质量要求，包括产品的几何形状和尺寸内部***和性能以及产品光洁度三个方面。

The rolling of steel is the core of the whole rolling process. The blanks are rolled to complete the deformation process. The rolling process plays a decisive role in the quality of the product. The quality requirements of rolling products include three aspects, including the internal structure and performance of the geometric and dimensional accuracy of the products and the finish of the products.

以一些小型冷轧机来说，由于它们大可配置75KW的电机，因此设备的轧制速度大也就达到3米每秒。而一些大型高延性盘螺冷轧机生产线来说的话，其电机的功率本身就很大.

For some ***all cold rolling mills, because they can be configured with the largest 75KW motor, the rolling speed of the equipment is as high as 3 meters per second. For some large high ductile cold rolling mill production lines, the power of the motor itself is very large.

轧钢机的技术现在越来越精细了，不同的类型，不同的物料都有不同的相对应的轧钢机设备，这也就让我们的物料更细致化了，且它们每一个地方的。

The technology of rolling mill is now more and more fine, different types, different materials h***e different corresponding rolling mill equipment, which makes our materials more detailed, and they are perfect every place.
