The function of the ingot bar is to be driven from the ingot storage device by the driving device in the ingot storage device, through the tension straightener, and then driven by the tension straightener, through the billet guide section, the secondary cooling device, and sent to the mold copper Under the mouth. During casting, the casting billet is led out of the copper tube of the mold. Using the driving force generated by the tension leveler, the slab is sent from the secondary cooling device and the slab guide section into the tension leveler. When the drawbar is out of the pull leveler, it is separated from the billet under the action of the pull leveler and enters the starter storage device, waiting for the next work.
