Alloy aluminum smelting slag when the main component is a mixture of aluminum oxide, aluminum nitride, and other oxides, aluminum content of the ash in the furnace just removed aluminum alloy is 45% -75%, so the aluminum alloy ash processing can be reduced to some extent, the cost of production. Aluminum alloy of aluminum ash recovery is closely related to the cost of recycled aluminum products, but the recovery of aluminum from aluminum alloy ash, the greater the difficulty, the higher recoveries. So now most of the recycled aluminum recycling companies to avoid excessive size from aluminum alloy aluminum ash, but instead sold the aluminum dross aluminum or steel slag processing plant Deoxidizer plant. What factors will lead to the mechanical properties of aluminum alloys fail? 1, not homogenized ingot processing, the Ingots precipitated Mg2Si phase can not squeeze in a relatively short time to re-solid solution, resulting in a solid solution is not sufficient to affect the performance of aluminum alloy products; 2, improper aging process, Hot air circulation or thermocouple mounting position is incorrect, resulting in inadequate or excessive aging aging; 3, ingot component failure, the ingot of Mg, Si content is not up to standard requirements; 4, at the outlet of a small aluminum alloy fan Shandong Aluminum brand machinery, air flow is not enough, leading to slow cooling, can not make aluminum alloy in the shortest possible time dropped to below 200 ℃, so coarse Mg2Si precipitates prematurely, allowing the solid solution phase to reduce the impact of heat-treated aluminum alloy performance; 5, when the temperature is too low aluminum alloy aluminum extrusion purposes, extrusion speed is too slow, the outlet temperature profile in the extruder reach the solution temperature, would not achieve the solid solution strengthening effect. _ _ Use aluminum rolls aluminum Alcoa Aluminum Co., Ltd. is provided by Jinan rolls.
