    Along with the production of hot-rolled steel a large amount of mixture of mill scale water and oil is constantly generated. It is of great importance to thoroughly separate these components from one another to make them recyclable. In the current research work an industrial trial was carried out at an ArcelorMittal hot-rolling mill for producing clean mill scale with negligible oil by

  • 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.
