<p><P>PROBLEM TO BE SOLVED: To provide a steel billet cutting method capable of correctly cutting a steel billet to the length of the requested weight. <P>SOLUTION: In the steel billet cutting method, a strand S drawn from a casting mold 14 by a pinch roll 18 by using a continuous casting machine is cut to a steel billet of the requested length having the requested weight which is obtained by correcting the nominal unit weight by the correction coefficient calculated based on information on the casting condition. The continuous casting machine is divided into a plurality of zones along the casting direction, and the corresponding fixed points are set on the terminal end of each zone. The final fixed point is set at the downstream position of the continuous casting machine in which solidification of the entire section of the strand is completed. The zone staying time in which the strand at the position corresponding to the steel billet to be cut stays in each zone is reflected to the calculation of the requested length of the steel billet. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
