Abstract

The invention discloses an anti-rusting high-magnesium aluminum alloy round ingot and a manufacturing method thereof and relates to an aluminum alloy round ingot and a manufacturing method thereof. The invention aims to solve the problem that the anti-rusting high-magnesium aluminum alloy round ingot is low in yield. The ingot mainly comprises the following elements: 0.40-0.8% of Mn, 8.3-9.6% of Mg, 0.004-0.05% of Sb and 0.05-0.15% of Ti. The preparation method comprises the following steps: weighing raw materials, charging and smelting according to a sequence, performing convective mixing, introducing into a holding furnace of a resistance reflection furnace, refining argon-chlorine mixed gases, standing, degassing, and finally casting the ingot. The yield of the ingot disclosed by the invention exceeds 85%, and the problem that an ingot prepared by the conventional method is low in yield is solved. The corrosion resistance and thermal crack resistance of the alloy are improved, and crack tendency is reduced. The preparation method in the invention is applicable to preparation of the anti-rusting high-magnesium aluminum alloy round ingot.

Description

Technical field [0001] The invention relates to a rust-proof high-magnesium aluminum alloy round ingot and a manufacturing method thereof. Background technique [0002] The rust-proof high-magnesium aluminum alloy is an Al-Mg-Mn series of rust-proof aluminum. The alloy is used for corrosion-resistant, weldable, and load-bearing components, such as skins, frameworks, and bulletproof materials. It has high strength and good Stress corrosion resistance and spalling resistance, good quenching sensitivity, compressive stress resistance and other advantages. However, due to the complex chemical composition, complex phase composition and high Mg element content of this alloy, the Mg element burns severely during the smelting process. Therefore, in the past production, the Mg element content of the sample after the furnace did not meet the standard requirements, resulting in the whole furnace being scrapped. Moreover, it shows a great tendency to crack during casting. The range of melti...
