1. Hot rolling and rolling defects: 1.1 Front and back tensions
Oils, soap emulsions, fatty acids are used as lubricants during hot rolling non-ferrous metals. Mineral oils, paraffin, fatty acids are used for cold rolling. Normally, foe ferrous alloys no lubricant is used. 1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills.
Integrated Scheduling of Reheating Furnace and Hot Rolling
In the hot rolling mill, a cold slab is reheated in reheating furnace and then rolled into thin coils through hot rolling process. Traditional research on hot rolling mill generally takes the two processes as two separate single-objective scheduling problems, though they are closely connected and their optimization objectives are conflicting with each other.

Hot Strip Mill
Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling …
Hot Rolling
When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.

How Rolling Mills Work in Steelmaking | OneMonroe
It's important to note that rolling mills support both cold rolling and hot rolling processes. Cold rolling means the sheet metal is pressed between the rollers at or near room temperature. Hot rolling, on the other, means the sheet metal is pressed between the rollers at a temperature above the metal's recrystallization point. Cold …
What Is A Rolling Mill?
What 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.
