实现金属轧制过程的设备。泛指完成轧材生产全过程的装备，包括有主要设备、辅助设备、起重运输设备和附属设备等。但一般所说的轧机往往仅指主要设备。
A device for a metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. Generally speaking, rolling mills usually refer to only the main equipments.
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.
在经过改进之后，目前的轧机设备采用的是被动一轧一拖式生产方式，可以实现两道轧制成型，不仅解决了速度配合问题，而且改变了传统的四道轧制方式，生产效率明显提高。
After the improvement, the current mill equipment adopts a passive one rolling and towing mode of production, which can realize two rolling forming. It not only solves the problem of speed matching, but also changes the traditional four way rolling method, and the production efficiency is improved.
