Background

The converter is a rotary metallurgical furnace that uses blown air, pure oxygen or pure oxygen plus fuel oil (or natural gas, steam, carbon dioxide) to oxidize impurities in the liquid metal and produce the required thermal energy. In order to prevent the furnace mouth from deforming and facilitate the removal of sticky slag during the operation at high temperature, a water-cooled furnace mouth which is forcibly cooled by circulating water is generally adopted, the water-cooled furnace mouth can keep the furnace mouth clean, the slag bonding is reduced, the deformation of the furnace mouth can be reduced, and the service life of a furnace lining at the furnace mouth is prolonged. Therefore, how to prolong the service life of the water-cooling furnace mouth and ensure the use reliability of the water-cooling furnace mouth puts higher requirements on the reliability of the water supply and drainage device of the water-cooling furnace mouth and the convenience of maintenance.

The water-cooled furnace mouth has two structures of a water tank type and a buried pipe type, the water tank type water-cooled furnace mouth is welded by steel plates, a plurality of partition plates are welded in the water tank, so that cooling water entering the water tank forms a snake-shaped loop, and the partition plates simultaneously play the role of rib plates and increase the rigidity of the water-cooled furnace mouth. This structure has high cooling strength and is easy to manufacture, but is more likely to burn through than a cast iron buried pipe type, and has low cooling water use efficiency. The buried pipe type water-cooling furnace mouth is formed by burying and casting a snakelike steel pipe which is filled with cooling water in cast iron. The structure has higher safety and service life than a water tank type furnace mouth, but the cooling effect is not as good as that of a water tank type furnace mouth.
