Description

Technical Field

[0001] The utility model relates to the technical field of aluminum melting furnaces, in particular to a non-stick aluminum prefabricated part for aluminum melting furnaces. Background Art

[0002] It is well known that during the aluminum melting operation of the aluminum melting furnace, the slag line of the aluminum melting furnace is in direct contact with molten aluminum and air for a long time, which causes the furnace bricks at the slag line of the aluminum melting furnace to be easily corroded and damaged. In order to ensure the normal use of the aluminum melting furnace, the existing solution is to install prefabricated bricks with better corrosion resistance at the slag line of the aluminum melting furnace, thereby slowing down the corrosion of the bricks at the slag line of the aluminum melting furnace by molten aluminum.

[0003] The prior art discloses a composite structure non-stick aluminum preform for an aluminum melting furnace with a publication number of CN220039096U, comprising an arc segment brick body, wherein the inner arc surface of the arc segment brick body is provided with a thin-walled groove, wherein a composite brick group having higher corrosion resistance than the arc segment brick body is adapted to be filled in the thin-walled groove, wherein the composite brick group comprises a plurality of brick units stacked up and down; the non-stick aluminum preform can ensure the service life while further reducing the maintenance cost;

[0004] Although the above scheme can effectively slow down the corrosion of molten aluminum on bricks, since each brick is bonded and fixed by refractory cement or refractory slurry during the construction of the aluminum melting furnace, in the subsequent disassembly and replacement of the corroded and damaged brick units, whether it is a hollowing method or a knocking and breaking method, it not only requires the staff to spend a lot of manpower and material resources, but also easily causes damage to the uncorroded and damaged brick structure. In addition, when replacing and installing new brick units in the subsequent process, the cleared position needs to be smoothed and trimmed, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a non-stick aluminum preform for an aluminum melting furnace. The use of the non-stick aluminum preform can not only effectively slow down the erosion and damage of the preform by molten aluminum and delay its service life, but also greatly facilitate the subsequent knocking, crushing and cleaning of the reinforced bricks that have been corroded and damaged, thereby greatly reducing the work difficulty of the staff and improving the work efficiency of the staff.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A non-stick aluminum preform for an aluminum melting furnace comprises a bottom brick body, wherein the bottom brick body is formed integrally by mutually perpendicular side brick plates and a lower brick plate, wherein the side brick plates and the lower brick plate cooperate to form an L-shaped release opening, wherein a high-temperature alloy plate which contacts with the inner wall of the release opening and is in an L-shaped structure is bonded in the release opening, and a reinforcing brick which is adapted to the release opening and can resist the erosion of aluminum water is bonded on the high-temperature alloy plate.

[0008] Furthermore, the high temperature alloy plate is made of nickel-based alloy, molybdenum alloy or titanium alloy.

[0009] Furthermore, the reinforcing bricks are made of magnesia-chrome bricks or magnesia-carbon bricks.

[0010] Furthermore, both ends of the high-temperature alloy plate are located in the corresponding side brick plates and lower brick plates, and the two ends of the high-temperature alloy plate cooperate with the corresponding side brick plates and lower brick plates to form steps, and the steps are filled with refractory cement for bonding and fixing the bottom brick body and reinforcing bricks.

[0011] Furthermore, bosses matching the corresponding steps are provided on the back surface and the lower surface of the reinforcing brick, and the bosses are bonded to the steps.

[0012] Compared with the prior art, the utility model has the following beneficial effects: through the cooperation of the bottom brick body and the reinforced bricks, the parts in contact with the molten aluminum and the air are reinforced bricks, and the reinforced bricks made of magnesia-chrome bricks or magnesia-carbon bricks can greatly improve the corrosion resistance and effectively extend the service life of the aluminum melting furnace;

[0013] By setting up high-temperature alloy plates, when replacing and maintaining the eroded and damaged reinforced bricks, the high-temperature alloy plates can not only be used to block and protect the underlying bricks, so that the staff can simply and directly knock and break the reinforced bricks to clean them, but also the stable structure of the high-temperature alloy plates provides great convenience for the subsequent replacement and bonding of new reinforced bricks;

[0014] By setting steps and bosses, the reinforced bricks can be effectively bonded and fixed to the bottom bricks during installation, which not only effectively improves the firmness and stability of the bond between the reinforced bricks and the bottom bricks, but also covers and protects both ends of the high-temperature alloy plate, preventing the aluminum liquid from contacting the high-temperature alloy plate, and effectively ensures the tightness of the overall structure of the aluminum melting furnace;

[0015] The utility model utilizes a non-stick aluminum prefabricated part composed of a composite structure, so that during the aluminum melting operation, the part on the prefabricated part that the aluminum liquid contacts is a reinforced brick with better corrosion resistance. The use of the non-stick aluminum prefabricated part can not only effectively slow down the corrosion damage of the aluminum liquid to the prefabricated part and delay its service life, but also greatly facilitates the subsequent knocking, crushing and cleaning of the reinforced bricks damaged by corrosion, as well as the bonding and installation of new reinforced bricks, which greatly reduces the work difficulty of the staff and improves the work efficiency of the staff.
