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.

横轧成型的特点是：1.两个工作轧辊轴线平行，其转动方向相同； 2.轧件轴线与轧辊轴线平行，轧件作转动，其转动方向与轧辊相反，进出料需专门装置。

The characteristics of the cross rolling are as follows: 1. the axis of the two working rolls is parallel and its rotation direction is the same; the axis of the 2. piece is parallel to the axis of the roll, and the rolling piece is rotated. The direction of the roll is to the roll, and the special device for entering and le***ing the material is needed.

生产过程实现自动化的目的是提高工件质量，用有限资源制造持久耐用的精美产品。实现自动化，可以提供质量好，性能稳定，价格合理的产品，为企业生产发展提供更大的空间。

The of automation of production process is to improve the quality of workpiece, and to produce durable and exquisite products with limited resources. The realization of automation can provide products with good quality, stable performance and reasonable price, and provide more space for the development of enterprise production.
