Brief Introduction to Four-High Rolling Mill

Jingyi Company is a comprehensive factory specialized in manufacturing embossing roll, embossing rolling mill (for metals), and rolling aluminium sheet with pattern (this kind of industrial structure is rare in China).

For the sake of overcoming defects of traditional rolling mill including small scope of rolling thickness, unevenness, easy to migrate, andsoon. Jingyi has experienced many failures in the course of repeated experiments at all research costs and with plenty of time, finally, “profound point” of the structure of Four-High Rolling Mill came into being along with the lucky advent of an inspiration after summarizing experiences and cudgeling our brains. And it is this supreme idea by many years’ incubation that those defects of rolling mill have been overcome. At the same time, the truth of “genuine knowledge comes from practice” is proved to the full extent.

At first hearing, it is not rare and there is nothing extraordinary just for it will get stronger strength by alternating four pattern rolls.

It is wrong! There is important technical parameters and special technology (of course, it is a commercial secret that cannot be given away). Otherwise, how can a rolling mill (Φ420mm, breadth 1360mm) with such a wide span (0.3-0.4mm) roll sheet also thick plate? And how can the rolled sheet and plate be so smooth?

The more gratifying achievement is that, because of its advanced technology, right-and-left deviation is not prone to occur when rolling. The cost for equipping with roll collecting unit and roll releasing unit is reduced greatly, and thus about hundreds thousand RMB can be saved.
