整个轧钢生产过程总是有以下几个基本工序组成的：

坯料准备，包括表面缺陷的清理，表面氧化铁皮的去除和坯料的预先热处理等。坯料的加热，是热轧生产工艺过程的重要工序。

The whole rolling process of steel rolling is always composed of the following basic processes:

Preparation of the billet, including the cleaning of surface defects, the removal of the iron oxide skin on the surface, and the pre heat treatment of the blank. The heating of the billet is an important process in the process of hot rolling.

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.
