Description

Technical Field

[0001] The utility model belongs to the technical field of electrode junctions and relates to a separator capable of extracting slag oxides in molten iron. Background Art

[0002] Hot metal pretreatment refers to a hot metal treatment process that removes impurity elements or recovers valuable elements before the hot metal is added to the steelmaking furnace. It includes hot metal desiliconization, desulfurization, and dephosphorization (commonly known as the "three dephosphorizations"), as well as vanadium extraction, niobium extraction, and tungsten extraction from hot metal.

[0003] The raw materials of molten iron contain impurities. After smelting, floating slag, impurities, oxides and other residues remain on the surface of the molten iron. Manual slag removal is labor-intensive. Mechanized slag removal requires a large investment. The slag removal effect varies greatly, resulting in large differences in the appearance quality of the product blank. Therefore, we designed a separator that can extract slag oxides from molten iron. Summary of the Invention

[0004] The purpose of the utility model is to provide a separator capable of extracting slag oxides in molten iron, so as to solve the problems raised in the above background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a separator capable of extracting slag oxides in molten iron, comprising a separator shell, two slots and a hanger, the two sides of the top of the separator shell being connected to the two slots through a slot connector, and the top of the separator shell being welded and installed to the hanger.

[0006] In the above-mentioned separator capable of extracting slag oxides in molten iron, a plurality of molten iron flow holes are provided on the surface of the separator shell, and the heat resistance of the separator shell is ≥1600°C.

[0007] In the above-mentioned separator capable of extracting slag oxides in molten iron, the opening of the hanger is equal to the length of the separator shell.

[0008] In the above-mentioned separator capable of extracting slag oxides in molten iron, the slot connector has a semicircular structure.

[0009] Compared with the existing technology, the advantages of the separator of the utility model that can extract slag oxides in molten iron are: it can effectively save electricity costs, reduce the consumption of slag cotton and slag collecting agents, reduce labor intensity, and improve the purity of molten iron, thereby reducing the internal residue and surface slag porosity defects of the casting, thereby improving the appearance quality of the casting blank.

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 and Figure 2 As shown, the utility model is a separator capable of extracting slag oxides in molten iron, comprising a separator shell 1, two slots 2 and a hanger 3. The two sides of the top of the separator shell 1 are connected to the two slots 2 through slot connectors 4, and the top of the separator shell 1 is welded and installed with the hanger 3; a plurality of molten iron flow holes are opened on the surface of the separator shell 1, and the heat resistance of the separator shell 1 is ≥1600℃.

[0015] The opening of the hanging handle 3 is equal to the length of the separator housing 1; the slot connector 4 has a semicircular structure.

[0016] When in use: the separator consists of three parts: a separator shell 1, two card slots 2 and a hanging handle 3.

[0017] Hang the separator to the outside of the ladle through the slots on both sides. When the molten iron is smelted, move the ladle to the front of the furnace and inject molten iron (requirements: ① The amount of molten iron injected must not exceed the highest point of the separator, otherwise the slag and impurities cannot be separated; ② The amount of molten iron injected should be as low as possible below the lowest point of the separator to avoid excessive surface tension of the molten iron when the separator is taken out).

[0018] Note: The best effect of avoiding slag and debris can be achieved after taking out the ladle from the separator before pouring.

[0019] During the molten iron injection process, the small holes on the separator wall divert the filtered pure iron water into the ladle.

[0020] After the molten iron is diverted to the ladle, the separator is lifted out by the lifting handle, and then the slag, impurities and oxides in the separator are discharged into the slag collection ladle through special equipment.

[0021] It can effectively improve the purity of molten iron, further reduce slag porosity defects on the surface of castings, and improve the appearance quality of casting blanks.

[0022] Furthermore, the shape and size of the separator housing 1 can be adjusted according to the actual situation to adjust the size of each unit (card slot, hanging handle, separator housing), but the internal structure and principle remain unchanged.

[0023] Matters not described in detail in this specification constitute prior art known to those skilled in the art. The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art to which the present invention relates may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
