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.

纵轧是纵向轧制的简称，是被轧物体通过两个反向转动的轧辊得到加工的轧制方法，轧制时轧件通过辊面间缝隙向前运动，其运动方向与轧辊轴线垂直。我们从轧钢机整个装配的过程来看，轧钢机中轴承以及轴承座在受力的情况上都是比较良好的。纵轧是轧制中***常见的一种轧制方法，横轧是轧件围绕自身中心线在轧辊间旋转，并且轧件旋转中心线与轧辊轴线平行，轧件只在横向受到压力加工的一种轧制的方法。

Longitudinal rolling is the abbreviation of longitudinal rolling. It is the rolling method of rolled object through two reversing rolls. When rolling, the workpiece moves forward through the gap between the rolls, and its direction of motion is perpendicular to the axis of the roller. Longitudinal rolling is the most common rolling method in rolling. Cross rolling is a rolling method for rolling pieces that rotate around the center line between the rolls, and the axis of the rolling piece is parallel to the axis of the rolls. The rolling piece is only subjected to pressure on the transverse side.

轧钢工业生产中的自动化是根据现场控制对象的检测值与设定值的偏差，按预定方式自行调整控制量使输出稳定在设定范围的控制过程。精整的工序通常又包括钢材的卷取，轧后冷却，矫直，成品热处理，成品表面清理以及各种涂色等许多具体工序。从工程技术上看，可以把过程自动化具体理解为：再各种不同的生产过程中，采用自动检测、电动执行等自动化装置和电子计算机，组成控制系统。

Automation in rolling industry is a process in which the output is stabilized in a set range by self-adjusting the quantity according to the deviation between the measured value and the set value of the field object. From the point of view of Engineering technology, process automation can be understood concretely as follows: in different production processes, automation devices such as automatic detection, electric execution and electronic computers are used to form systems.
