Problems solved by technology

[0003] However, the existing aluminum alloy ingot casting method has the following defects: it is not conducive to increasing the tensile strength and hardness, it is not conducive to pouring into ingots, Na is not conducive to entering the metal matrix, and the phenomenon of "sodium brittleness" is prone to occur; it is not conducive to reducing the aluminum liquid blanking If the speed is high, a large amount of molten aluminum will splash, and the molten aluminum will not be fully contacted during blanking, which will cause agglomeration; in view of this defect, it is very useful for us to design an aluminum alloy and ingot casting method produced by a metal melting and casting process. necessary

Abstract

The invention discloses an aluminum alloy produced with a metal casting technology and an ingot casting method. The aluminum alloy is prepared from components in percentage by weight as follows: 4%-12% of Si, 4%-6% of Fe, 1%-3% of Ni, 3%-5% of V, 2%-6% of V, 2%-6% of Na, 2%-6% of Mg, 1%-3% of Bi and the balance of Al and 0.5%-1% of impurities. The ingot casting method comprises the steps as follows: S1, Si, Fe, Ni, V, Mg, Al and impurities are all put into a furnace, refining is performed after smelting, aluminum ash on the surface of molten aluminum in the furnace is thoroughly stripped afterrefining, the site is cleared, a furnace door is closed after slagging off, any other operation on the molten aluminum in the furnace is prevented, and the molten aluminum is left to stand for 15 min. The effects of increasing tensile strength and hardness are realized, the discharging speed of the molten aluminum can be decreased, the splash amount can be reduced, and meanwhile, the molten aluminum can be fully contacted during discharging and cannot cake.

Description

technical field [0001] The invention relates to the technical field of metal melting and casting technology, in particular to an aluminum alloy and an ingot casting method produced by the metal melting and casting technology. Background technique [0002] Metal melting and casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. The rough blank after melting and casting is almost formed, so that the purpose of free machining or a small amount of processing reduces the cost and reduces the time to a certain extent. Melting and casting is one of the basic processes of modern machinery manufacturing industry. Ingot casting is a very important link in the metal melting and casting process. [0003] However, the existing aluminum alloy ingot casting method has the following defects: it is not conducive to increasin...
