<p>PURPOSE:To prevent the useless rolling of a billet by suspending the biting of a billet to a rolling mill by the signal of a detector when a cooling floor is filled up by rolled stock and performing the OFF line processing from the transfer table of the billet. CONSTITUTION:A detector 1 detecting the storing state of the rolled stock stored in the cooling floor 41 following a bar steel rolling mill group 37 is provided. When the cooling floor 41 is filled up with rolled stock, the bitting of a billet into the rolling mill 37 is suspended with the signal from the detector 1. Simultaneously, at least either one processing of the takeup processing of the billet to a heating furance 35 or the processing by an offline table 7 from the transfer table of the billet is performed. Consequently, the heat energy held by the billet can effectively be utilized.</p> |
