Jul 23, 2017· Rolling chatter is the result of interactions between the rolling process and the mill structure, as well as between consecutive stands on a tandem mill. Based on two friction models which are widely employed in industry, the rolling process model is conducted in this research by considering the material strainhardening effect and the work roll flattening effect.

Figure 1 A typical rolling scheduling procedure for the setup of a tandem cold rolling mill. 4. The forward slip ratio f i (1 ≤i≤N) at each stand is calculated from the BlandFord forward slip formula, hence yielding the location of the neutral point of roll bite. 5. Based on the torque formula derived by Bryant [3], the roll torque G i (1 ≤i≤N)
A complete modernization of the 5Stand 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 ...
It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types. The tandem mills consist of number of non reverse roll mill arranged in one after other as shown in figure.
