Design of Rolling Mills | Metallurgy - Your Article Library

The diameter of rollers may vary from 0.2 to 1.5 m with width of 0.3 to 5 m. Rollers are subjected to very severe service conditions during rolling process, such as combined bending and torque, friction, wear, and thermal conditions. To resist these conditions, rollers are usually made of high-quality steel, and sometimes from high-grade cast iron.

GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD …

The plastic deformation of steel during the rolling process generates heat, which is absorbed by the work rolls – figure 1 .Heat is carried by the rolling stock (by virtue of its temperature) and some is lost to the air and to the wash-off coolant before reaching the roll bite.

Hot Rolling - an overview | ScienceDirect Topics

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.
