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.
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.
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.
