The speed of the rolls varies during the pass when heavy ingots are rolled in reversing blooming or slabbing mills. A typical diagram showing the variation. Fig. 4.9 Variation in Roll Speed and Torque in a Blooming Mill during Rolling. in roll speed for a two-high reversing mill is shown in Fig. 4.9.
Finally, Fig. 10 shows a load step variation from 0% to with the motor at nominal speed: the good system response can be observed, in particular the calculated speed drop area is equal to 0.1 % s (of the maximum speed). 0 .9 9 9 6 0 .9 9 9 7 0 .9 9 9 8 0 .9 9 9 9 ConclusionsA new synchronous motor drive for rolling mill applications, with ...
Input values for setting mill motor speeds are production rate, roll collar diameters and roll gaps, bar areas and widths, and gear ratios. Motor speed ratings are normally checked against calculated speeds. Mill utilization. Mill utilization is a measure of the percentage of time that the mill is rolling steel.
