Embodiment 1

[0030] The formula of the high-yield-strength aluminum alloy provided in this embodiment is by weight percentage:

[0031] Si: 0.3%~9%; Fe: 0.6~1.3%; Cu: 0.1~2.5%; Mn: 0~1.8%; Mg: 0~1.5%; Ni: 0~0.7%; Ti: 0~0.1%; Sb: 0-0.1%; Zn: 2-19%; Pb: 0-0.01%; the balance is Al.

[0032] The key smelting technology of this embodiment includes a surge-type permanent magnetic stirring device, including a melting furnace 1, a permanent magnetic stirring magnet 2, and a permanent magnetic partition 3. The permanent magnetic partition 3 is located near the bottom of the melting furnace 1 and is located at the permanent magnetic stirring magnet 2. Above, the magnetization direction of the permanent magnet separator 3 is perpendicular to the plane of the permanent magnet separator 3, the area of ​​the permanent magnet separator 3 is less than the area of ​​the bottom of the smelting furnace 1, and the magnetic field strength of the permanent magnet separator 3 is less than that of the permanent m...

Abstract

The invention discloses a high-yield-strength aluminum alloy formula and a smelting key device thereof. A provided yield-strength die-casting aluminum alloy has the good casting property, mechanical property and heat treatment property, and meanwhile has the high yield strength. The key device for smelting the alloy with the compositions comprises a melting furnace, a permanent magnet stirring magnet and a permanent magnet partition plate; the permanent magnet partition plate is close to the bottom of the melting furnace and located on the upper portion of the permanent magnet stirring magnet;and the magnetization direction of the permanent magnet partition plate is perpendicular to the plane of the permanent magnet partition plate, the area of the permanent magnet partition plate is smaller than that of the bottom of the melting furnace, and the magnetic field strength of the permanent magnet partition plate is smaller than that of the permanent magnet stirring magnet. A space between the melting furnace and the permanent magnet stirring magnet is partially filled with the permanent magnet partition plate, and thus a non-uniform magnetic field in space and a pulse magnetic fieldin time are provided; and through the non-uniform magnetic field in space and the pulse magnetic field in time, non-uniform driving force is applied to the interior of metal liquid, and thus the surgeeffect is formed.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to the formulation of high-yield-strength aluminum alloys and key smelting devices thereof. Background technique [0002] Aluminum alloy is a common lightweight metal material. It is widely used in industries such as automobiles, ships, aerospace, machinery, and communications. It has the characteristics of good processing performance, light weight, and energy saving. With the continuous development of the automobile industry, the requirements for light weight and low energy consumption of automobiles have become a major trend in the automobile manufacturing industry, and the demand for aluminum alloy, which is the first material for light weight, in automobiles is also expanding. Most of the aluminum alloy parts used in automobiles are formed by casting. Compared with other processing methods, casting has high metal utilization rate and high dimensional accuracy. It can pro...
