Abstract
PURPOSE:To eliminate the need for cutting, reheating, etc., improve yield, etc. and reduce cost by controlling the casting quantity of the casting machines according to the loop quantity formed between rolling mills or the material speed in the specific rolling mill. CONSTITUTION:Molten steel 21 is casted through casting mold 3 to a slab 4 which is then subsequently fed to roughing mill groups 141, etc., intermediate rolling mill groups 171. etc. and finishing mill groups 181, etc. At this time, the speed of drawing rolls 5 is so controlled by the mechanisms such as speed reference setter 19, molten liquid level height detector 27, etc. of the roughing mill groups 171, etc. that the molten liquid level of the casting mold 3 becomes contact and at the same time the specified loop 15 is formed before the intermediate rolling mill group 171 and when this loop 15 exceeds the specified range, the nozzle stopper 22 in the tundish 1 is driving controlled by the control mechanisms consisting of a loop height detector 30, position detector 24, servo pump 26, cylinder 23, etc., whereby the loop 15 is so controlled that it goes within the specified range.
