2 PLI in the internal zone then decrease to PLI in the rewind zone. Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size,

Rolling of steel in Hot Strip Mill – IspatGuru

Dec 03, 2015· 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 %.
