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.

驱动电机斜置在锯机底座上，通过伞齿轮及主传动轴带动锯片，锯片由液压装置锁紧在传动轴上。锯片进锯由液压驱动，进锯速度根据锯切阻力由比例阀调节。当轧件断面较大、锯切阻力高时，进锯速度慢，反之，进锯速度块。

The driving motor is inclined on the base of the saw machine, and the saw blade is driven through the bevel gear and the main drive shaft, and the saw blade is locked on the drive shaft by the hydraulic device. The sawing saw is driven by hydraulic pressure, and the speed of the saw is adjusted by the proportional valve according to the cutting resistance. When the section of the rolled piece is large and the cutting resistance is high, the speed of the saw is slow, and conversely, the speed block of the saw.

轧机在轧制过程中由轧制力所引起的内力沿机座各承载零件分布的应力曲线，称作应力线。为了提高轧机刚度，减少机架及各承载零件的变形，采取各种技术措施后，将这种应力线缩短了的轧机，称为短应力线轧机。它是高刚度轧机中的一种。

The stress curve of the rolling force, which is caused by the internal force of the rolling force, along the bearing parts of the frame, is called the stress line. In order to improve the rigidity of rolling mill and reduce the deformation of rack and bearing parts, after taking various technical measures, the mill which shortens the stress line is called short stress line mill. It is one of the high rigidity rolling mills.

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（Leonardo da Vinci）设计出轧机的草图。1553年法国人布律列尔(Brulier)轧制出金和银板材,用以制造钱币。此后在西班牙、比利时和英国相继出现轧机。

It is said that there are rolling mills in Europe in the fourteenth Century, but it is recorded that in 1480, Leonardo Da Vinci (Italian Italian designer Da Finch) designed the draft for rolling mills. In 1553 the French law Adler cloth (Brulier) rolled gold and silver plate, used in the manufacture of coins. Since then, rolling mills h***e been rolled out in Spain, Belgium and Britain.
