HOT STEEL ROLLING - figures

At the present time hot rolling mills can produce up to one mm thickness but the usual minimum thicknesses are limited at 1.5 mm especially when rolling velocity reaches 15 ms and over. Steel wire can be hot rolled with diameters as small as 5 mm at velocities as high as 100 ms. Perhaps the major drawback of hot rolling is the surface ...

Scale formation and its removal in Hot Rolling process

During hot rolling of steel its surface is exposed to air which leads to oxidation resulting in scale formation. The scale formation is affected by the temperature steel grade surrounding atmosphere and the exposure time. There are two kinds of scales relevant in rolling mills †sticky and dry scales.

Hot Strip Mill - an overview | ScienceDirect Topics

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 tandem cold mill.
