It was shown the concept for the optimum mill modulus distribution that the controllability of tandem cold rolling mills could be raised by changing the mill modulus of every rolling stands in tandem cold rolling mills 46) , it is necessary to consider the change with time of tension between each stand in cold strip rolling, and to consider.
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.
Jan 09, Their research activity was aimed to assess an approach suitable to model the cold rolling cluster mill Xu et al formulated a single-stand chatter model for cold rolling by coupling the dynamic rolling process model, the roll stand structure model and the hydraulic servo system model They linearized the model and represented it as a transfer.
two-stand DCR cold rolling mill (DCR = Double Cold Reduction) The combined pickling line/tandem cold mill is a prime example of the newly developed high-tech mills and is designed as endless mill for an annual capacity of 134 million tons It is able to produce cold strip with a minimum thickness of 012 mm SPECIAL FEATURES.
than can be rolled by the Hot Mill Cold Rolling CSI’s cold reduction mill is a series of five rolling mills, or ‘stands’; hence the name “5-Stand” Each mill stand has two work rolls about two feet in diameter, which are driven by powerful electric motors (totaling over 25,000 horsepower) and sandwich the steel to reduce the thickness.
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1) Fig (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
