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.
轧钢生产对原料有一定的技术要求比如钢种，断面形状和尺寸，重量表面质量等。这些技术要求的考虑是保证钢材质量所必须的。也是确定和选择坯料时应具体要考虑的内容。
Steel rolling production has some technical requirements for raw materials such as steel, section shape and size, weight surface quality and so on. These technical requirements are cidered to be necessary to ensure the quality of the steel. It is also the content that should be cidered when determining and selecting the blank.
单就冷轧机的轧制速度而言，其型号就可分为两种，一种是每秒线速度在3米的冷轧机，还有一种则是线速度在20米冷轧机，后面这一种设备已经可以算得上是快的了。
As far as the rolling speed of the cold rolling mill is concerned, the model can be divided into two types, one is a cold rolling mill with a line speed of 3 meters per second, and one is the line speed in the 20 meter cold rolling mill, and the latter is the fastest.
选择一批具有行业轧钢机设备技术制高点，能带动轧钢机设备行业和技术提高的建设项目作为行业技术示范项目，***力量研制核心技术和关键软件，实现轧钢机设备自动化和计算机控制系统的国产化。
A batch of ctruction projects which h***e the technical height of the industry rolling mill equipment and the ctruction projects that can improve the equipment industry and technology of the rolling mill are selected as the demtration project of the industry technology, and the core technology and key software are developed to realize the localization of the automation of the rolling mill equipment and the computer system.
