  • Wrapper Roll Control System of Hot Strip Mill SpringerLink

    Wrapper roll is one of the most important components in rolling coiler. And it has great relation to the quality of the final products. Based on the programming and optimization experience, a hot strip coiler with new coiling process, which operates with position control and pressure control is introduced. Control method and operational modeHOT STRIP MILL DOWN COILERS Casey USA,The strip enters the downcoiler from a pinch roll and is immediately formed around the mandrel using wrapper rolls. Unlike a traditional coiler, a hot strip mill downcoiler utilizes a series of rolls and sensors to maintain tight and well aligned coil wraps. The downcoiler
