OPTIMIZED SHIFT STRATEGIES AS FUNCTION OF BANDWIDTH

摘要

The invention relates to a method for the optimization of shift strategies, as a function of the strip width, for best possible usage of the advantages of CVC/CVCSUPPlus /SUPtechnology in operation of strip-edge oriented shifts in 4-/6-roller stands, comprising a pair of working rollers and a pair of support rollers for a 4-roller stand and, in addition, a pair of intermediate rollers for a 6-roller stand, whereby at least the working rollers and the intermediate rollers cooperate with devices for axial shifting, characterized in that selection of the shift position (VP), for the shifting working/intermediate rollers, is made as a function of strip width. The working/intermediate rollers are then positioned in various positions (P), relative to the strip edge and, within differing strip width ranges (B), the shift position (VP) of each roller is given by an incremental linear progressive function.
