The Difference between Two-high Rolling Mill and Four-high Rolling Mill

The difference between Two-high Rolling Mill and Four-high Rolling Mill

Many friends do not know what is a four-roll mill. In fact, the four-roll mill is a combination of two working rolls and two supporting rolls. It belongs not only to the driving machine of backup rolls but also to the equipment driven by working rolls. Therefore, the specific choice should be made according to the requirements of customers, and also to the actual use situation.

What is the difference between a two-roll mill and a four-roll mill? For a two-roll mill, the whole diameter of the roll is relatively large, and the contact area between the roll and the tie piece is also very large, so the whole rolling force is relatively large, so there are certain requirements for the selection of rolling materials and thickness, so as to effectively avoid many unnecessary problems in the whole rolling process. Four-high rolling mill also increases in roll system, so its working roll diameter can be much smaller, so the corresponding rolling force will be much smaller, more suitable for rolling thinner materials, then the whole rolling thickness and scope will be more extensive.

The above content focuses on the different properties of different rolls of rolling mills. When choosing a rolling mill, we should first understand its own working properties, so that re-selection will be relatively simple.
