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.

辊系快速整体更换不需吊车，采甩轧辊牵引小车和横移台车结合的换辊方式，导卫横梁安装在轧机轴承座上，更换轧辊时,导卫及横梁随辊系整套从牌坊窗口中拖出，一次换辊时间仅为20min.

You don't need to replace the whole fast roller roller way for mining crane, trolley and swing roller tr***ersing trolley with the guide beam is installed on the bearing seat of rolling mill, roll changing, guide and beam with roll set pulled from the housing window, a roll change time is only 20min.

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.

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。轧制过程中立辊如失去平衡而引起上辊或下辊的窜动，上辊会与下辊同步调整，从而保证上、下腹板对中并控制腹板和翼缘的尺寸。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。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?Comparedwiththerollforgingprocess,theutilizationratioofmaterialsisraisedbymorethan10%ofthelaborproductivityby3050%。 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.
