Rolling (metalworking) Wikipedia

A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling

Advanced Process and Quality Control in Hot Rolling Mills

3.1 Key Feature of Process Control: Detection of Periodic Defects Rolls and rollers are the most heavily used parts of a rolling mill. Due to wear from contacting hot material with great force, their lifetime is limited. Although rolls are refurbished in the roll shop regularly, they occasionally crack before the end of the usual production cycle.
