Embodiment Construction

[0025] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention, not to limit the protection scope of the present invention. Improvements and adjustments made by skilled personnel according to the present invention in practical applications still belong to the protection scope of the present invention.

[0026] The following examples are given to illustrate the invention.

[0027] A kind of AlSi12Cu1Fe aluminum alloy ingot, its composition is represented by mass fraction as:

[0028] Si: 11.4%, Fe: 0.69%, Cu: 1.01%, Mn: 0.22%, Mg: 0.2%, Cr: 0.003, Ni: 0.007%, Zn: 0.01%, Ti: 0.02%, Pb: 0.001%, Sn :0.01%.

[0029] 4. The process for improving the appearance of the AlSi12Cu1Fe aluminum alloy ingot is as follows:

[0030] In addition to aluminum, the alloy composition mainly contains the following components by weight percentage:

Abstract

The invention relates to the technical field of aluminum ingots, in particular to a method for improving properties of an AlSi12Cu1Fe aluminum alloy ingot. The method comprises the following steps of: melting, slagging off, melting silicon, cooling, deslagging, refining, adding a modificator, degassing, standing, and casting an ingot. According to multiple tests on the appearance of the AlSi12Cu1Fe aluminum alloy ingot produced by the method, the tested results are that the appearance is good, and feedback is good after the tested results are fed to a user. The comprehensive properties of aluminum alloy ingot die castings produced by the method are superior to those of the aluminum alloy ingot die castings produced in the prior art.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a method for improving the performance of an AlSi12Cu1Fe aluminum alloy ingot. Background technique [0002] AlSi12Cu1Fe aluminum alloy ingot products are mainly used in the automotive industry. With the overall improvement of user requirements, the requirements for the appearance of aluminum ingots also increase. [0003] Due to the high silicon content of AlSi12Cu1Fe products, usually 10.5%-12.5%, such a silicon content requirement, if effective measures are not taken, aluminum ingots often have appearance cracks, and now many users require that aluminum ingots are not allowed to have cracks in appearance. Faced with the quality requirements of users, existing aluminum ingot producers cannot solve this problem, which limits the application range of this brand in the market. [0004] The operation of producing AlSi12Cu1Fe aluminum alloy ingots according to the existing...
