Abstract

PURPOSE:To make constant the breadth size of the metal strip, and to make possible the improvement of the product quality, in the control unit for the breadth of the rolled sheet, by controlling the broadside rolling edger, installed in front of the roughing mill, with the arithmetic unit for forecasting the breadth fluctuation in the rolling mill group. CONSTITUTION:In the array of the hot rolling mill line depending on the conventional method, various elements affecting the rolling work, like as the material of the metal strip to be rolled, the rolling load of the roughing mill, the set tension for finishing pass, etc., are set in the rolling condition setter 22; on purpose to make constant the product breadth by the arithmetic unit 23 depending on above data, the sheet breadth to be formed in the broadside rolling edger installed in front of the roughing mill, is operated for every position of the metal strip; the result of this operation is given by the breadth reduction command unit 24 to the hydraulic screw 10 as the command. Above unit 10 adjusts the gap of the broadside rolling rolls 17, 17, through the worm wheels 9, 21, etc., into the specified condition; hereby, the breadth size of the metal strip is continuously controlled so as to make constant the product breadth, so that the product quality is improved.
