specific Embodiment approach 1

[0022] Specific embodiment 1: In this embodiment, a flat cast ingot of aluminum alloy composite material skin is composed of Si: 9.50%-10.10%, Mg: 1.30%-1.70%, Na: 0.008%-0.02%, Be<0.005%, impurity and balance Al; said impurity is composed of Fe<0.40%, Cu<0.20%, Mn<0.10%, Ni<0.05%, Zn<0.10% and Ti<0.05% according to weight percentage.

[0023] In this embodiment, Fe, Cu, Mn, Ni, Zn, and Ti are all impurity elements. Impurities within this range have no effect on the molding and metallurgical quality of the ingot, and the lower the content in actual production, the better.

specific Embodiment approach 2

[0024] Embodiment 2: This embodiment differs from Embodiment 1 in that it is composed of Si: 9.80%, Mg: 1.50%, Na: 0.01%, Be: 0.001%, impurities and the balance Al according to weight percentage. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0025] Embodiment 3: This embodiment differs from Embodiment 1 in that it is composed of Si: 10.0%, Mg: 1.60%, Na: 0.015%, Be: 0.003%, impurities and the balance Al according to weight percentage. Others are the same as in the first embodiment.

Abstract

The invention discloses an aluminum alloy composite skin material flat ingot and a manufacturing method thereof, and belongs to the field of alloy ingot manufacturing. The problem that the yield of cast ingots is low due to the defects of air holes, slag inclusion and coarse grains of the aluminum alloy composite material skin flat cast ingots manufactured by the existing method is solved. The materials of the aluminum alloy composite skin material flat ingot consist of Si, Mg, Na, B, impurities and the balance of Al; and the impurities are Fe, Cu, Mn, Ni, Zn and Ti. The method comprises the following steps of preparing materials; obtaining an alloy melt after smelting; and refining the modified alloy melt and casting. By controlling the change of the ingot specification, the scientific proportion of the raw material components, the improvement of the modification process and the improvement of the casting process, the defects of pores, slag inclusion, coarse grains and the like of theingot are reduced, then the yield of the alloy ingot is improved, the yield reaches more than 91%, and the problem of low ingot yield prepared through the existing method is solved. The manufacturingmethod disclosed by the invention is suitable for manufacturing the aluminum alloy composite skin material flat ingot.

Description

technical field [0001] The invention belongs to the field of manufacturing alloy ingots, and in particular relates to an aluminum alloy composite leather material flat ingot and a manufacturing method thereof. Background technique [0002] The aluminum alloy composite skin material flat ingot is an aluminum alloy with a high silicon content in the Al-Si series alloy. It has the characteristics of low density, low thermal expansion coefficient, good volume stability, low melting point, good wear resistance and high temperature performance, etc. As the cladding layer of 434 composite aluminum strip and foil, it is widely used in the manufacture of radiators such as automobiles, air conditioners, and oxygen generators. In the past, the aluminum alloy composite leather flat ingot was cast by pasting the heat insulation film on the inner wall of the crystallizer. The quality of the product fluctuated significantly due to the quality of the heat insulation film. At the same time, ...
