Problems solved by technology

[0006] The commercially used refining agent is Al-5Ti-1B, and the modifying agent is Al-10Sr. After refining and modifying, the strength and plasticity of the alloy are improved to a certain extent, but coarse needle-shaped particles may appear in Al-5Ti-1B. TiAl3 phase, and the TiB2 phase as the nucleation center is easy to aggregate into clusters. In order to avoid the shortcomings of Al-5Ti-1B refinement and obtain aluminum alloy wheels with better mechanical properties, it is necessary to improve the refinement modifier and refinement method

Description

technical field [0001] The invention relates to the field of smelting and processing of aluminum alloys, and more specifically relates to an aluminum alloy refining agent, its preparation method and its application in refining aluminum alloys. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. The density of pure aluminum is small (ρ=2.7g / cm 3 ), about 1 / 3 of iron, low melting point (660°C), aluminum is a face-centered cubic structure, so it has high plasticity (δ: 32-40%, ψ: 70-90%), easy to process, and can be Made into various profiles and plates, it has good corrosion resistance; but the strength of pure aluminum is very low, and the σb value in the annealed state is about 8kgf / mm 2 , so it is not suitable for structural materials. Through long-term production practice and scienti...
