[0061] The method for preparing an aluminum alloy with high thermal conductivity for die-casting in this embodiment includes the following steps;
[0062] For S1-S6, step 1, at first, the ingredients are heated to a molten state in each feeding furnace 9; then, the molten ingredients are dripped into the quantitative storage tank 12 through the ingredient output pipe 10 from the gap; secondly, After the ingredients in the quantitative storage tank 12 reach the set weight, the quantitative storage tank 12 swings on the quantitative support 11 to be top-heavy, and the molten ingredients flow down from the upper opening 13 of the feed to the electric heating furnace 7 of the corresponding station; again, according to the setting temperature, the electric heating furnace 7 of each station is heated to the set condition, and it is stirred in the stirring tank of the quantitative storage tank 12; then, the configured ingredients are output at the lower discharge station 22;
