Gauge control using estimate of roll eccentricity |
摘要 |
A method of controlling a rolling mill in which eccentricity of the roll assemblies of the mill and variations in the thickness and/or hardness of material entering the mill ordinarily adversely affect the gauge of the material leaving the mill. The method involves the steps of slowly eliminating the cyclic effects of roll eccentricity on the exit gauge of the material while simultaneously correcting for the adverse effects of incoming gauge variations. This is accomplished by continually estimating a change in exit gauge using the standard gaugemeter equation but correcting the equation with continuing estimates of backup roll eccentricity, until the cyclic effects of such on exit gauge are essentially reduced to zero.
