PURPOSE:To transfer a slab on bloom freely changing materials gap and transfer speed, by a method wherein the slab on bloom is transferred between the beams operating a suitable transfer distance by detecting the position of slab or bloom on the before stage beam in a split-type reheating furnace and then the after stage beam is operated. CONSTITUTION:Slabs on blooms 2e and 2f to be transferred are charged by an optional gap onto the before stage beam 1a of split-type reheating furnace. The position of slab on bloom 2e is detected with a detector 12 and the slab on bloom 2e is transferred between the beams operating the transfer distance from the detector 12 until the gap between the slab on bloom 2e and the slab on bloom 2d on the after stage beam 1b becomes a settled gap G. Then, the slab on bloom 2e is transferred to the original position of transferred slab on bloom 2d within the beam by operating the after stage beam. Those transfer between the beams and transfer within the beam are alternately carried out and the transfer between the beams is carried out by a fixed gap. By this method, the material transfer speed can be optionally changed and the utilization efficiency of reheating furnace can be improved in walking beam reheating furnace. |
