Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic stirrers, in particular to a single furnace metal melt stirring component. Background Art

[0002] During the metal smelting process in a single furnace, an electromagnetic stirrer is often used on the outer wall surface of the bottom of the single furnace to achieve stirring and homogenization of the molten metal in the single furnace, thereby improving product quality and production efficiency. However, the magnetic surface used by existing electromagnetic stirrers is mostly a full-surface structure, and the magnetic force on the molten metal is concentrated in the same area, and cannot be dispersed to the molten metal in different areas, resulting in insufficient power for the circulation of the molten metal, resulting in reduced metal smelting efficiency. In addition, the existing electromagnetic stirrer adopts a full-surface magnetic surface structure, which causes the heat of the magnetic surface to increase during continuous operation, and the temperature of the molten metal to be stirred is also very high. Excessive temperature will reduce the magnetic strength of the electromagnetic stirrer and reduce the power for the circulation of the molten metal.

[0003] Furthermore, electromagnetic stirrers with a full-surface magnetic surface structure can often only be installed on the outer wall of a single furnace, and a reinforcing rib plate structure is also provided between the electromagnetic stirrer and the outer wall of the single furnace, which increases the distance between the electromagnetic stirrer and the molten metal in the single furnace, reduces the magnetic force of the electromagnetic stirrer on the circulation of the molten metal, and leads to a decrease in metal smelting efficiency.

[0004] In summary, a single furnace metal melt stirring assembly is needed to solve the problem that the existing electromagnetic stirrer adopts a full-surface magnetic surface structure, which leads to reduced metal melting efficiency. Utility Model Content

[0030] Multiple groups of reinforcing rib assemblies 1.2 are also spaced apart on the magnetic window 1, and the groove 1.1 is formed between two adjacent reinforcing rib assemblies 1.2. Specifically, each reinforcing rib assembly 1.2 includes a first reinforcing rib plate single piece, a second reinforcing rib plate single piece, and a third reinforcing rib plate single piece; the first reinforcing rib plate single piece and the second reinforcing rib plate single piece are both symmetrically arranged on the magnetic window along the depth direction of the groove 1.1 facing each other; the third reinforcing rib plate single piece is arranged to cover the end of the first reinforcing rib plate single piece and the second reinforcing rib plate single piece away from the magnetic window, forming the reinforcing rib plate assembly 1.2, which is used to enhance the strength of the magnetic window 1 and improve operational safety.

[0031] The depth of the groove 1.1 is 30-300 mm; the height of the magnetic pole protrusion 2.1 above the main cover 2.2 of the first electromagnetic stirrer 2 is 30-300 mm, so that the electromagnetic stirrer 2 is close to the molten metal, the magnetic force on the molten metal is increased, the circulation of the molten metal is accelerated, and the smelting efficiency of the molten metal on the unmelted metal is improved.

The molten metal (such as molten aluminum, molten zinc and molten copper, etc.) in the single furnace is accelerated to circulate under the action of the magnetic force provided by the electromagnetic stirrer 2, thereby improving the smelting efficiency of the molten metal to the unmelted metal. Among them, the electromagnetic stirrer 2 adopts a one-to-one adaptation arrangement of multiple magnetic pole protrusions 2.1 and multiple grooves 1.1, which facilitates the electromagnetic stirrer 2 to approach the molten metal, increase the magnetic force on the molten metal, and use multiple magnetic pole protrusions 2.1 to form a dispersed magnetic field, which can exert magnetic force on the molten metal in different areas, accelerate the circulation of the molten metal, and improve the smelting efficiency of the molten metal to the unmelted metal; multiple magnetic pole protrusions 2.1 are set on each of the electromagnetic stirrers 2 to form multiple raised and separated magnetic surfaces, so as to avoid the problem of concentrated increase in heat on the magnetic surface and reduced magnetic strength during continuous operation.
