A novel mass flow controller for tandem hot rolling mills

In tandem hot strip rolling mills, the roll speed of the mill stands is synchronized to ensure a uniform mass flow A uniform mass flow is desirable to keep the strip tension constant and thus avoid large movements of the loopers which are located between the mill stands in order to control the strip tension This also improves the general thickness quality and prevents the strip from necking• Multiroll mills • Twostand mills • DCR mills • Tandem mills • Temper mills • Foil mills Significant quality parameters The significant quality parameters are: material thickness, material shape and surface, and the homogeneity of stress distribution For opti mized costefficiency and to maximize material usage, tight tolerances for the thickness are vital, to enable theTechnological Controls for Cold Rolling Mill ABBBased on workpiece geometry : Multiple backing rolls allow even smaller roll diameters Various configurations of rolling mills: (d) cluster mill Cluster Mill 22 Variousconfigurations of rolling mills: (e) tandem rolling mill Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section isMANUFACTURING PROCESSES FIT
