Simulation of the Longitudinal Thickness Deviation of the Steel Strips Hot Rolled in the Continuous Group of a Broad- Strip Mill
A model for the formation of longitudinal thickness deviation in hot-rolled strips as a function of the rolling parameters and an algorithm for optimizing the rolling conditions for the criterion of the minimum longitudinal thickness deviation are developed and implemented in the form of computer programs. This optimization is performed by the redistribution of percent reductions over the stands of the finishing group in a broad-strip hot-rolling mill. As a result of the application and industrial tests of the developed computer programs on a 2000 rolling mill, the longitudinal thickness deviation of hot-rolled strips is decreased by a factor of 1.87.
