Rolling of steel in Hot Strip Mill – IspatGuru

The combination of roll gap cooling, roll gap lubrication and improved exit side cooling systems reduces the roll temperature. This results in a thinner oxide layer on the roll surface with less work roll peeling for consequence. Lubrication inside the roll gap minimizes friction, thereby enabling rolling force reduction of 20 % to 30 %.
