The produced cast steel is cut to have a desired length by a torch cutting machine (TCM) installed at the rear end of the segment. The slab having been cut by the torch cutting device is transferred to the subsequent process through the feed roller of the roller table provided in the continuous casting equipment.
The torch cutting apparatus preheats a cutting torch provided in the torch cutting apparatus to a predetermined temperature, and then moves the cutting torch at a desired speed in the width direction of the cast steel to cut the cast steel. At this time, when the cutting of the main cutting edge is started by the operation schedule in a state where the preheating of the cutting torch is not sufficiently progressed, or when the cutting torch moving in the width direction of the main cooking cavity is moved faster than the target speed, A cutting area is generated.
On the other hand, when the cutting operation of the cutting tool of the torch cutting device is completed, the roller table drives the feed roller provided on the roller table to feed the cut piece. At this time, when the conveying roller is driven in a state where the main part is not cut, a twist phenomenon occurs in which the cast strip deviates from the main feed path on the roller table, so that the main part can not be smoothly conveyed. In addition, there is a problem in that the work load applied to the conveying roller by the twisting of the casting is increased. This causes damage to the roller table and disruption of the continuous casting process.
