  • 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 millssticky and dry scales.
