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.

Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
