The Hot Rolling Process - California Steel

finishing 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".

Four Types Of Rolling Mills | Metal ... - American Steel

This mill consists of a pair of heavy backing rolls surrounded by a large number of small planetary rolls. The main feature of this mill is that it hot-reduces a slab to coiled strip in a single pass. The operation requires feed rolls to introduce the slab into the mill, and a pair of planishing rolls on the exit to improve the surface finish.

Roll Pass design for hot flat rolling of plain carbon steel

Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls.

the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.
