采用控制轧制工艺时，为了防止原始奥氏体晶粒过分长大，一般采用较低的加热温度和开轧温度。由于开轧温度高，变形后的奥氏体晶粒会发生再结晶而细化，如在这个阶段停止变第八节控制轧制技术形，轧件即随温度下降而产生相变。

In order to prevent the original austenite grain growing too much, the lower heating temperature and rolling temperature are generally adopted in the rolling process. Due to the high rolling temperature, the austenite grain after the deformation will be recrystallized and refined. For example, the eighth section rolling technology is stopped at this stage, and the phase change is produced as the temperature drops.

轧辊的弹性压扁沿辊身长度散布是不匀称的，若边部延伸率大。轧机支持辊的外貌肖氏硬度1样平常为HS45左右，在另1侧设专人观察，也会出现相反的环境，薄钢板通常以卷板和剪切成肯定长度和宽度的单张板投放市场。

The elastic flattening of the roll is uneven along the length of the roller body, and the elongation at the side is large. The appearance of the rolling mill support roll is about 1 HS45, which is normally observed on the other 1 sides, and the environment will occur. Thin plates are usually put on the market with rolled plates and a single sheet that is cut to a certain length and width.

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.
