Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting equipment, in particular to a device for removing surface residues of a smelting furnace. Background Art

[0002] A smelting furnace is a furnace that melts iron ore, such as hematite or magnetite, to make pig iron. The furnace is a tall cylindrical structure lined with refractory material, and is filled from the top with selected ore, coke and solvent (usually limestone). The conversion of iron oxide to metallic iron is a reduction process, in which carbon monoxide and hydrogen are used as reducing agents.

[0003] When using a traditional smelting furnace surface residue removal device, it is not easy to adjust the insertion depth and tilt angle of the residue box, making the residue box more convenient in collecting the smelting furnace surface residue, and making the residue collected in the residue box easier to remove, so as to continuously clean the residue in the smelting furnace.

[0004] After searching the existing Chinese patents: a device for removing slag from the surface of a smelting furnace (Announcement No.: CN219869088U), including a smelting furnace and a crossbeam, the crossbeam is located directly above the smelting furnace, a position adjustment component is installed below the crossbeam, a bearing seat is installed on the position adjustment component, a first rectangular frame plate is fixedly installed on the bearing seat, a first motor is fixedly installed on the top of the first rectangular frame plate, and a first threaded screw is rotatably connected between the relative inner walls of the first rectangular frame plate through a bearing, the first threaded screw is driven by the first motor, and a carrier plate is threadedly connected to the first threaded screw. The first motor drives the first threaded screw to rotate, so that the first threaded screw adjusts the position of the carrier plate in a screw transmission manner, thereby driving the position of the slag box to be adjusted, so that the residue box can be adjusted according to the liquid level of the molten metal in the smelting furnace, and the residue on the surface of the molten metal can be better removed.

[0005] Although the above patent can adjust the position of the residue box and clean the residue on the surface of the molten metal by setting a residue box, the disadvantage is that when the residue box scoops up the residue, a part of the molten metal is also scooped up, so that the molten metal will also be poured out when the residue is poured out, which causes a waste of molten metal in the process of cleaning the residue, which is not conducive to production efficiency.

[0006] Therefore, it is necessary to invent a device for removing slag from the surface of a smelting furnace to solve the above problems. Utility Model Content
