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.

轧制速度控制：即轧制时对各道次轧辊的线速度以及每道中不同阶段的轧辊的速 度的具体规定，也叫速度规程。

Rolling speed : that is to say, the speed regulation is also specified for the speed of each roller and the speed of each roller different stages in rolling.

轧钢原料：

目前主要为连铸坯，另外还有钢锭，段轧钢等，正确的选择坯料的种类，断面形状和尺寸大小以及重量对轧钢生产具有重要意义。

Rolling material:

At present, mainly for continuous casting billets, as well as steel ingots, section rolling, etc., correctly choose the type of billet, section shape and size and weight are important for steel rolling production.

生产过程实现自动化的目的是提高工件质量，用有限资源制造持久耐用的精美产品。实现自动化，可以提供质量好，性能稳定，价格合理的产品，为企业生产发展提供更大的空间。

The of automation of production process is to improve the quality of workpiece, and to produce durable and exquisite products with limited resources. The realization of automation can provide products with good quality, stable performance and reasonable price, and provide more space for the development of enterprise production.
