Abstract
PURPOSE: To smooth the rolling work and to prevent the deterioration of quality of the rolled product, by keeping appropriate rolling speed before and after cutting the material with the cutter being arranged between the continuous casting facilities and the rolling mill, at the continuous rolling work for the rod, bar, etc.
CONSTITUTION: The cutter 3 is installed between the continuous casting facilities consisting of the tundish 1, the mold 29, and the pinch roll 2, and plural units of rolling stands 4W6. Besides, the looper 26 is located between the first stage rolling stand 4 and the rear stage rolling stands 5, 6. When the billet 14 is cut by the cutter 3, the signal 24 is produced from the speed reference changeover circuit 16, and the speed reference circuit 13 of the rolling stand 5 holds the speed reference 32 at cutting work. By the circuit 17 for setting acceleration and accelerating time just after the cutting work of the first stage rolling stand 4, the speed reference circuit 44 of the rear stage rolling stand 5 and the speed reference circuit 12 of the first stage rolling stand 4, the first stage rolling stand 4 is accelerated just after the cutting work is finished, and then, is decelerated to the speed of the rear stage rolling stand 5; hereby, the rolling becomes possible without changing the speed after the looper 26.
