Abstract
PURPOSE: To easily obtain highly accurate thickness of rolling strips even when the thickness is thin and the length of the strip is relatively long in a controlling method for the thickness of rolling strips by using a gauge meter formula, by fixing the offset term of the formula at an average thickness of ≥2 passes and a measured value of the length of the steel strip.
CONSTITUTION: The gauge meter formula is expressed by the formulaI(where, h is the thickness of strip at the outlet side of rolling mill, S is the roll interval when no load is applied, F is the rolling load, M is the elastic coefficient of the rolling mill, δ is a compensating term for the thickness of oil film fixed by the number of revolutions of roll and the F, and α is an offset term). When, for example, a rolling is performed while the rolling width is maintained constant as in the case of gauge controlled rolling pass of thick plate rolling, it can be presumed that α is a constant between at least two passes out of continuous several passes. Therefore, the thickness Hi of a pass (i) is expressed by the formula II (where, the GMi is (S+F/M+δ)i). Moreover, when the length of the strip at the pass (i) is Li, the formula III (where, ρ(Ti) is approximately true. α Can be fixed from the formula II and III when formulas IV and V are solved, that is to say, when the length of strip at least between two passes and the thickness of the gauge meter are measured.
