A stand of a cold tube-rolling mill is formed by a housing and work rolls. Mounted in pairs on the housing are uprights arranged opposite to the axis of rolling. The work rolls are mounted one above the other in the bearing supports between pairs of lower and upper backup rolls mounted in corresponding bearing chocks. The upper bearing chocks are adapted for vertical setup motions.

A complete modernization of the 5-Stand tandem cold reduction mill was completed in 1997. This unit now has a capacity of more than 1 million tons annually. In the cold rolling process, pickled and oiled coils pass through five stands, arranged in tandem with a predetermined amount of reduction taken on each stand until the final thickness is ...
Jan 01, 2015 Conclusion 1. It is a good practice to use the principle of the three-stand mill modeling developed at investigation of rolling mills with different number of the continuous stands. 2. The actual rolling mill has been quantitatively evaluated with regard to the force interaction of the electric drives at fluc-tuations of the rolling conditions. 3.
