If the low iron funnel is scabbed, cracked, loose or deformed, it must be replaced, and check whether there is any foreign matter in the brick inner hole, and whether the interface is consistent, etc. The iron wire must be reinforced for the middle column pipe brick to prevent the quality accident caused by the bursting of the middle column pipe when pouring steel and the quartz sand rushing into the steel ingot. The mold slag must be baked, otherwise, the quality of the steel ingot will be affected by the damp, which is not conducive to the effective feeding of the cap mouth. When laying the brick type, the bedding layer of quartz sand at the bottom of the flow steel trough shall also be thoroughly checked to see whether there is large sand and cold steel, which will affect the flatness of the flow steel brick.
