Abstract

PURPOSE:To control the thickness especially so as to exclude the thickness deviation on the exit side of the rolling mill, by obtaining various dimensions of thickness on the exit side of the first stand from the rolling load and the actually measured draft position, and by adjusting the draft position according to the signal produced from above various dimensions, so as to make the exit side thickness for every stand following to the first stand to be the aim value. CONSTITUTION:The draft position is set according to the schedule calculation, before the material is fed to the first stand. Then, for every feed of the material into respective stand, the prediction error of the average deformation resistance, that is the plastic deformation constant of the material, and the thickness error on the exit side, are calculated depending on the actually measured value at present time. As a result, the draft position of the stand in downstream of this stand is immediately corrected before the material is fed into: hereby, the product with aim thickness from the tip end of the material is obtained at high accuracy.
