tachometers on drive rolls or deflector rolls at the entrance and exit to the mill stand These contact techniques measure the speed of the spinning roll rather than direct strip speed The assumption is that the roll will spin at the same speed as the strip However, in practice, this is not always true and depends on the conditions of contact ....

Jan 24, 2019 0183 32 Figure 2a shows the schematic of the overall arrangement of rolls in hot strip mill There are a number of rolls with specific functions There are bend rolls, deflector rolls and entry rolls, and all of these fundamentally allow the workpiece to enter the forming roll in the desired alignment where reduction in thickness takes place...

Oct 26, 2021 0183 32 Appropriate work roll shifting strategy in the finishing hot strip mill can make roll wear uniform and contour smooth To eliminate the problem of roll shifting position duplication due to available roll shifting strategy, the optimized work roll shifting strategy is proposed in the hot strip rolling mill with continuous variable crown work rolls, using the k-nearest neighbors algorithm...

the roll and strip First asperity contact occurs with Λs below about 3, so that to give substantial asperity contact and a good imprint of the smooth rolls onto the strip, Λs needs to be below about 1 Figure 41 b shows schematically the contact in these circumstances, with areas of contact between the roll and strip and areas separated by...
