[0014] Example
[0015] According to the raw material ratio of 6061 high-strength aluminum alloy (calculated by 10 tons furnace): aluminum-chromium alloy 0.25 tons, aluminum-silicon alloy 0.3 tons, aluminum-magnesium alloy 1.1 tons, iron agent 0.07 tons, aluminum-copper alloy 0.065 tons, primary aluminum 7 tons, 1.2 tons of 1060 leftovers.
[0016] Process:
[0017] (1) Feeding: First add 1060 leftovers to the furnace and then add primary aluminum, and stir while melting to melt the leftovers; (2) Add various alloys according to the ratio of raw materials, and stir fully until completely melted.
[0018] (2) Melting process: first melt the leftovers and then add the primary aluminum, fully stir to melt the leftovers; when the temperature reaches 690-710℃, add other raw materials according to the formula, heat and stir until all melted, then heat the melt to 730-750 ℃. Because the primary aluminum temperature is relatively high, when the primary aluminum temperature is lowered to 6...
