The rolling mills used for cold strip steel include two-high mills, four-high mills and multi-high mills. The most widely used is the four-high mill. Rolling thinner products requires a multi-roll mill. There are many types of multi-high rolling mills, such as six-high rolling mills, partial eight-high rolling mills, twelve-high rolling mills, twenty-high rolling mills, etc.
