Abstract

PURPOSE:To improve plate thickness accuracy by measuring the mill constants of rolling mills in a touch roll state during rolling and subsequently correcting gauge meter formulas by these measured mill constants. CONSTITUTION:The plate thickness H is obtained by the gauge meter formula of exit side plate thickness H=SO+ST+SW+SOIL from the rolling mill deformation amount ST in the state where the material to be rolled has passed the rolling mills and the next material to be rolled is not bitten yet, the rolling mill deformation amount SW at the test material pressure-sandwiching, screw position (work roll gap) SO and oil film thickness SOIL. As for this SW, the data obtainable in the experiments to be done about once or twice a year are used. ST is expressed by (n) piece polynominals using only the rolling pressure F as variables and by on-line correcting the ST formula by the touch roll method, the mill constant fluctuations are compensated and the gauge meter formula accuracy is considerably improved.
