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 telping coil sides and irregular wraps on a coil.
Rolling mill equipment, components assemblies include hot leveler cassette assemblies, uncoilers, roller tables, entry shears, feed roll assemblies, pinch roll assemblies, and cooling beds for hot strip rolling mills, skin-pass mills, and tandem mills.

Roll wear in a hot strip mill (HSM) is a detrimental process, which progressively worsens the rolls. This necessitates replacement of the rolls after rolling a number of strips. Roll wear adversely affects the strip shape and the performance of a mill. It is important, therefore, to quantify roll wear during the rolling process.
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
