同时在了解技术要求的同时，我们还必须充分了解各种钢的内在特性，尤其是加工工艺特性及***性能的变化特性，即该钢种的固有内在规律，然后利用这些规律，我们才能真确的制订生产工艺过程及采取有效地工艺手段，来达到生产出合乎技术要求的产品目标。

At the same time to understand the technical requirements at the same time, we must also fully understand the inherent characteristics of all kinds of steel, especially the characteristics of manufacturing process characteristics and organizational performance, namely the inherent inherent law of the steel, and then use these rules, make production process and take effective technical means we true, to produce a the technical requirements of the product target.

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.

轧钢机在辊系的装配上，主要的应该是轴承的使用，虽然短圆柱的轴承在寿命上都比较长，而且承载的能力也比较大，但是，其不可以承受轴向力，因为使用的是双列较的接触轴承.

The main part of the rolling mill assembly of the roll system should be the use of the bearing. Although the bearing of the short cylinder is long in life, and the capacity of the bearing is relatively large, it can not bear the axial force, because the use is a double row of contact bearing.
