Here are a few of the main types of rolling mills: Continuous rolling mill. Sheet metal passes through several rolling stands, each pressing the metal thinner. Cluster rolling mill. A cluster of metal rolls are lined up to be thinned out. An example of a cluster rolling mill would be a 20-High Cluster Rolling Mill.

INTRODUCTION. The need to expand production and improve the quality of thin-sheet cold-rolled metal requires the improvement of existing broad-strip cold rolling mills and creation of new high-performance and economical ones. The most important parameters of a wide-strip cold rolling mill include the rolling speed, the weight of rolled …
