A method and system for furnace pacing in a mill are disclosed herein. Billets are extracted from a furnace and provided in an alternating fashion to two or more strands of a multistrand stand. The timing of the extraction of each of the billets from the furnace, i.e., the furnace time, is based at least in part on a prediction of the rolling times of a previously extracted billets at the strands of the multistrand stand and a desired gap between the billets. Likewise, the actual rolling time of each billet is measured and compared with the predicted rolling time of the billet to generate a correction factor associated with the billet. The furnace time of a subsequent billet intended for a same strand as a previously extracted billet is adjusted by the correction factor associated with the previously extracted billet to regulate the gaps between billets at each strand of the multistrand stand, thereby increasing the productivity of the mill while reducing the potential for collisions between billets.
