What Are the Types of Rolling Mill Roll?
02/07/2020· Rolling mill roll is a tool for plastic deformation of rolled metal, which is an important consumption part to determine the efficiency of rolling mill and the quality of rolled products. Roll is an important part of rolling mill. The rolling pressure of a pair or group of rollers is used to roll steel. It mainly bears the influence of static and dynamic load, wear and temperature change during rolling.
Metallurgy of Rolling mill Rolls – IspatGuru
13/11/2019· Frictional force – In the rolling mill, the roll and the material being rolled are both pressed together by the same load. Hence for the movement of the material being rolled between the roll gap, a force is necessary. The amount of force depends on the surface conditions shape, and roughness etc. as well as on the coefficient of friction between the roll material and the material being rolled. The situation in the roll

GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD
Thermal aspects of rolling . 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. In the roll bite the strip gains heat from friction between strip and roll and
