Description

Technical Field

[0001] The utility model relates to the technical field of dust removal covers for casting residue, and more specifically, to a ground mobile dust removal cover for casting residue. Background Art

[0002] Casting residue is a mixture of molten steel and casting residue remaining in the ladle after continuous casting or ingot casting of the molten steel in the ladle. After each pouring of the molten steel in the ladle, a certain amount of liquid casting residue always remains in the ladle, and the amount of liquid casting residue is about 30 kg / t of steel. For these casting residues, the method of using a crane to pour the residual casting residue in the ladle into a ground slag pot and then transporting the slag pot filled with casting residue to the slag yard for further treatment is mostly adopted.

[0003] Currently, with the increasingly strict environmental protection standards in the iron and steel industry, each steel mill attaches great importance to flue gas treatment and up-to-standard discharge. When the ladle is discharging slag, a large amount of flue gas and dust will inevitably be generated, and these pollutants floating in the workshop will have a serious impact on the surrounding environment. Therefore, it is necessary to develop a new type of dust removal device and method to solve these problems. Content of the Utility Model
