<p>PURPOSE:To improve an interval pitch control by absorbing mill pacing error in a finish mill on a hot rolling line. CONSTITUTION:When time required to carry a preceding rolled stock and a succeeding rolled stock are predicted based on the carrier pattern of a preset stock to be rolled, the time extracting the succeeding rolled stock from a heating furnace is corrected by the actual result of the preceding rolled stock, the time at which the preceeding rolled stock passes through the 1st stand of finish mill is predicted and a waiting time at a coil box for the succeeding rolled stock is adjusted, the succeeding stock is waited until the most adequate time comes to the interval pitch from the preceeding rolled stock, then, the succeeding stock is delivered from the coil box to the finish mill, thus mill pacing high in precision and small in temperature drop can be actualized.</p> |
