At present, there is a trend of using bucket steel rolls to replace forged steel rolls. The roll of the 6VH billet continuous rolling mill in the Baosteel blooming mill is made of forged semi-steel and forged cast iron with 1.7% ~ 2.4% C, which has good wear resistance and poor hot crack resistance.
Fig 1 Components of a roll stand. Housing – Housing creates a framework of the rolling mill stand and for absorbing the total metal pressure on rolls during the process of rolling. Hence, the housing is to be solid and its structure is to enable easy and fast roll changing. Also, there need to be easy access to all parts of the housing and other details of the roll stand.

The earliest example we have of rolling technology are proto rolling mills, dating back to about 600 B.C. Found in South Asia and the Middle East, these operated using the same basic principles as those drawn by Da Vinci during the Italian Renaissance. Though Da Vinci sketched the idea for rolling machinery, it was not produced during his lifetime.

Hot-rolled coils (HRC) are a type of sheet product resembling a wound steel strip and are produced at hot-rolling mills. These products are widely used for construction, the machine industry, car manufacturing, the production of general-purpose, construction, oil and gas and special-purpose pipes, and as a work-piece for the further production of cold-rolled products.
M.-C. Theyssier, in Welding and Joining of Advanced High Strength Steels (AHSS), 2015 3.2.2.2 Hot rolling. Depending on the grade composition (alloying and microalloying contents) and on the hot rolling schedule, the strain hardening at each pass of the roughing and finishing mills and the dynamic recrystallization ability between the passes vary.
