AI Technical Summary

Benefits of technology

This patented inventor describes an improved way to make high-quality circular aluminium castings by making them through various methods like casting or rolling. These techniques help save on cost while maintaining their strength properties at least comparable compared to traditional processes that use molten metal from previous manufacturing steps.

Problems solved by technology

This patented technical problem addressed in this patents relates to producing high-quality Al alloys (such as AA6062) from larger sizes or higher diameters than previously possible due to poor machine toolability during manufacturing processes such as extrusion moldings. Current methods involve melting raw materials into slabs before they enter the final forming step, resulting in surface defects like cracks and bubbles along their edges when compared to smaller sizing options made up entirely of solidified material. There is thus a strong desire within industry for improved products' exterior appearances while maintaining interior qualities.

Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing:

[0038] Such as Figure 1 to Figure 4 Shown: the present invention is by weight percentage: 0.42%~0.44%Si, 0.50%~0.55%Mg, 0.005%~0.03%Ti, 0~0.18%Fe, 0~0.025%Zn and the chemical composition composition of surplus Al .

[0039] The production method of above-mentioned large-diameter 6063 aluminum alloy round ingot is as following technological process:

[0040] A. Melt smelting process

[0041] Add cold material and part of the Al-Si intermediate alloy into the melting furnace, use the siphon to introduce the electrolytic aluminum liquid into the melting furnace, add modifiers, ingredients, and complete the melting process through electromagnetic stirring.

[0042] B. Melt refining process

[0043] After smelting, the melt goes through furnace bottom blowing, powder spraying refining, slag removal, and standing still, and then transfers to a static furnace, where bottom blow...

Abstract

The invention discloses a production method of a large diameter 6063 aluminum alloy round ingot casting billet comprising the chemical components by weight of 0.42%-0.44% of Si, 0.50%-0.55% of Mg, 0.005%-0.03% of Ti, 0-0.18% of Fe, 0-0.025% of Zn and the balance of A. The method omits remelting process, reduces the cost of aluminum per ton, greatly reduces aluminum burning loss, reduces greenhouse gas and toxic gas emissions, increases environmental benefits, greatly avoids crack, shrinkage cavity, shrinkage, air hole and other quality defects of the 6063 aluminum alloy round ingot casting billet, inhibits drawing stamp, unsmooth skin, cold shut, local aluminum leakage and other surface technical problems, improves the microstructure and mechanical properties of a large diameter aluminum alloy bar, avoids the production of cold cracks, improves the rate of finished products of the large diameter aluminum alloy round ingot casting billet, reduces the recycled amount of the waste, saves energy consumption, and reduces emissions of exhaust gas and pollutants so as to achieve the purpose of energy saving, and has remarkable social benefit and environmental benefit.
