Description

Technical Field

[0001] The utility model relates to the technical field of aluminum strip casting and rolling, in particular to an iron removal device for a front box of an aluminum strip casting and rolling. Background Art

[0002] The raw materials of aluminum strip are pure aluminum or aluminum alloy cast-rolled aluminum coil and hot-rolled aluminum coil, which are rolled into thin aluminum coils of different thicknesses and widths by cold rolling mill, and then longitudinally cut into aluminum strips of different widths by slitting machine according to the purpose. The aluminum strip is rolled into shape by casting and rolling mill. The casting and rolling mill is equipped with a front box for buffering aluminum liquid. Part of the raw materials of aluminum liquid comes from scrap aluminum, which contains ferromagnetic impurities. If they are not removed, it will affect the quality of the aluminum strip and cause the product to fail to meet the standards.

[0003] After searching, it was found that the publication number is CN218015661U, and the name is an aluminum liquid iron removal device for the front box of aluminum strip casting and rolling. The application proposes that at this stage, equipment using magnetic adsorption for iron removal has appeared, but it still requires manual operation, which is more troublesome, and the electromagnetic iron scooping equipment used for aluminum liquid needs to be moved out of the front box when removing the iron adsorbed on the surface. In the process of removing the iron adsorbed on the surface, it is impossible to continue to remove iron from the aluminum liquid, affecting the efficiency of continuous iron removal. When removing iron from the aluminum liquid, the high-temperature resistant electromagnet for scooping iron is moved left and right. When removing iron from the aluminum liquid, the second drive motor can be started to drive the screw to rotate, and then drive the slide seat threadedly connected to the screw to move, driving one of the high-temperature resistant electromagnets for scooping iron to be placed directly above the front box of the casting and rolling mill, and then, the hydraulic rod contracts, driving the top frame and one of the high-temperature resistant electromagnets for scooping iron to move downward, and one of the high-temperature resistant electromagnets for scooping iron enters the interior of the front box of the casting and rolling mill, contacts with the aluminum liquid, and adsorbs the iron in the aluminum liquid by magnetic force. After adsorption for a period of time, the hydraulic rod extends. The second drive motor drives the screw to rotate in the opposite direction, driving one of the high-temperature resistant electromagnets for scooping iron to reset while driving the other high-temperature resistant electromagnet for scooping iron to be located just above the front box of the casting and rolling mill. Subsequently, the hydraulic rod contracts again, driving the other high-temperature resistant electromagnet for scooping iron to enter the aluminum liquid and continue to adsorb and scoop iron. One of the high-temperature resistant electromagnets for scooping iron moves to the top of the chain plate conveyor. After power is cut off, the adsorbed iron falls to the top surface of the chain plate conveyor and is transported out. The high-temperature resistant electromagnet for scooping iron alternately adsorbs and removes iron and puts the adsorbed iron onto the top surface of the chain plate conveyor to complete continuous iron removal, thereby improving the efficiency of aluminum liquid iron removal and eliminating the trouble of manual operation. It is more convenient to use. However, when removing iron, the application needs to first change the height, and then adjust the position of the high-temperature resistant electromagnet, and then needs to lower the height. The steps are relatively cumbersome. At the same time, it is necessary to set up a lifting and moving mechanism, the structure is relatively complex, and the operation is relatively troublesome. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
