  • Wrapper Roll Control System of Hot Strip Mill | SpringerLink

    高达12%返现· 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 mode,

  • HOT 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 eliminates telescoping coil sides and irregular wraps on a coil.

  • Pacific InternationalFORGED ROLLS FOR HOT STRIP MILL,

    FORGED ROLLS FOR HOT STRIP MILL & CONTINUOUS CASTER. Pinch Rolls are manufactured in accordance with our customer’s requirements, depending on the rolled steel quality in high or low chromium execution. Wrapper Rolls are manufactured according to the application conditions with electroslag welding or with thermal coating.

  • Highest performing Hot Strip Mills | Primetals Technologies

    The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability,
