保持工作辊的上辊和下辊相对于轧机中心线对称且在轴线方向上移动。这种的工作辊移动的设计，是用来改变工作辊和支撑辊的偏移需要大的移动量。这种大移动量的采用需要大量的改装费用，并且需要解决很多问题.
The upper and lower rolls of the work roll are symmetrical and move in the direction of the axis of the rolling mill. The movement of this work roll is designed to change the shift of work rolls and support rolls to require large amounts of movement. The use of this large shift of momentum requires a lot of modification costs, and many problems need to be solved.
开坯机为两辊水平轧机，坯料送至轧机前后，根据轧制程序表进入相应的轧槽可逆轧制，并通过翻钢装置将轧件夹紧进行翻转。一般轧制5-7道次(多9道次)。
The blooming machine is a two roll horizontal mill, and the billet is sent to the front and rear mills. According to the rolling schedule, the roll is rolled into the corresponding rolling groove, and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).
机架是轧钢机的主要部件，它在轧钢过程中承担金属变形给予的负荷。因此要求机架有足够的强度和刚度，以保证设备安全和产品质量。型钢轧机的机架形式较多，常见的机架形式有开口式机架、闭口式机架和半闭口式机架3种。
The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to h***e sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.
辊式轧机生产率可以很高，有的可达到2000-4000 件/小时甚至更高，易于实现自动化生产。总之，辊式轧机适用于对产品精度要求不高，且同时轧制一个或几个零件的情况。辊式轧机是三种类型中运用多的一种。Nextwewillfindoutthespecificcontent。圆弧式轧机适用于大批量的为以后锻造供坯的生产情况。
The productivity of the roller mill can be very high, some can reach 2000-4000 pieces / hour or even higher, and it is easy to realize automatic production. In conclusion, the roll mill is suitable for the low accuracy of products and rolling one or several parts at the same time. Roll mill is the most widely used in three types. The circular arc mill is suitable for large quantities of production for forging later.
