轧钢，就是在旋转的的轧辊间改变钢锭，钢坯的形状的压力加工过程。所谓轧钢工艺过程就是一系列轧钢工艺过程组合而成的加工流程。

Rolling is the process of changing the pressure of the ingot and the shape of the billet between the rotating rolls. The so-called steel rolling process is a process of combination of a series of steel rolling process.

在提高质量和产量的同时，还应该力求降低成本。因此如何能够高产，低成本的生产出合乎技术要求的钢材，是制定轧钢工艺生产工艺过程的总任务和总的要求。

At the same time, we should try to reduce the cost while improving the quality and production. Therefore, how to produce high quality and low cost steel that meets the technical requirements is the general task and the general requirement for making the rolling process production process.

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.
