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，600rolling mill， 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.
在对轧机进行分类的时候，一般是按照轧辊的排列和数目进行分类。下面我们就来了解下具体的内容。比如二辊轧机，其的主要特点就是结构简单、用途广泛，也包括可逆式和不可逆式两种。
When classifying rolling mills， they are generally classified according to the number and arrangement of rolls. Next we will find out the specific content. For example， two-high mill， its main features are simple structure， wide range of uses， including reversible and irreversible two kinds.
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，rolling mill，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，620rolling mill， mill professional manufacturers ， this kind of mill because of its advantages are not prominent， so the use of less. So，320rolling mill， what are the characteristics of the four high rolling mill? 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.
