轧机前后有对中导卫的升降辊道，可保证轧件正确进入轧机。三架轧机的辊系和轴承座同步更换，更换平台在轧线外侧，换辊时间长只用20min。传动侧的牌坊，通过液压方式，由张力螺杆锁定，操作侧的牌坊为“可拉出”式，轧件导卫固定在水平轧机的轴承座上。据说在14世纪欧洲就有轧机，但有记载的是1480年意大利人达·芬奇（Leonardod***inci）设计出轧机的草图。

A lift roller of the guide in the time before and after the mill, rolling mill can ensure the correct entering. The roll system of three rolling mills is replaced synchronously with the bearing seat, and the replacement platform is on the outside of the rolling line. The longest time for changing the roll is only 20min. The movable side arch is locked by tension screw, and the operation side arch is "pull-out" type, and the rolling guide is fixed on the bearing seat of the horizontal rolling mill.

连续加热炉连续加热炉包括推钢式加热炉、步进式炉、转底式炉、分室式炉等连续加热炉，但习惯上常指推钢式炉。连续加热炉多数用于轧制前加热金属料坯，少数用于锻造和热处理。

It is named according to the varieties of rolling, the type of rolling mill and the nominal size. The principle of "nominal size"

For rolling mills, they are named after the gear ring and the pitch diameter of the herringbone gear.

轧制时毛坯的位置固定，因此不需设置侧向支撑毛坯的导向尺。总之，它适用于轧制复杂外形结构，精度要求高，零件品种变换很多的情况。但其行程大小受到限制，所以，变形程度也受到影响，同时，板式轧机有空行程，故影响到生产率和变形程度都不能很大。

The of the blank is fixed during rolling, so there is no need to set the guide bar of the side supporting blank. In short, it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited, so the degree of deformation is also affected. At the same time, the plate mill has an empty tr***el, so the productivity and deformation can not be very large.

轧机***厂家介绍，其实从实际生产作业来看，关于冷轧机的安全生产主要包括三个方面，分别为：定期检修、日常安全操作以及日常的培训管理等。

In fact, from the actual production operation, the safety production of the cold rolling mill mainly includes three aspects, which are the regular maintenance, the daily safety operation and the daily training etc.
