关于机械产量，二十世纪七十年代后期，控制冷却技术的发展使得钢板轧制中的TMCP技术得到广泛发展。
With regard to mechanical production, the development of cooling technology in the late 1970s made the TMCP technology develop widely in steel plate rolling.
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.
还有三辊轧机，轧机***厂家介绍，这种轧机由于本身的优势并不突出，所以使用的比较少。那么，四辊轧机具有怎样的特点恩？这种类型的轧机的工作辊直径较小，传递轧制力矩，轧延压力由直径较大的支承辊承受。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。其的优点在于相对刚度高、压下量大、轧延力小，比较适合轧制较薄的板材。
There are three-high mill, mill professional manufacturers , this kind of mill because of its advantages are not prominent, so the use of less. So, what are the characteristics of the four high rolling mill?六辊轧机，轧机***厂家介绍，这种轧机的辊系相对来说比较稳定，而且其主要是由一对工作辊和两对支承辊组成。 The working roll diameter of this type of mill is ***aller, the rolling torque is tran***itted, and the rolling pressure is borne by the backup roll with larger diameter. Its advantages are high relative stiffness, large reduction and ***all rolling force, so it is suitable for rolling thin sheets.
