Read OnOverview. Operation of a rolling mill, such as the two-high/four-high universal mill that produces slab and plate products, as well as blooms and billets, is unusual.The mill has an annual capacity of 140,000 tons, and consists of the following in-line equipment: mill approach table, descaler, mill stand, delivery table, hot bed, shear and exit section.
Read On4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Read Onfinishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

Read OnWhat Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
