Present invention seek to address that the deficiencies in the prior art, and a kind of smelting technology of high-strength/tenacity aluminum alloy is provided.
The present invention to achieve the above object, using following technical scheme：
A kind of smelting technology of high-strength/tenacity aluminum alloy, which is characterized in that specific melting step is as follows：
1) it configures furnace charge and furnace charge and smelting furnace is preheated respectively, take 10% foundry returns by mass percentage,
10% silicon metal, as furnace charge, the foundry returns is the steel scrap containing 15% silicon and 0.6% iron for 80% aluminium ingot, furnace charge and molten
Furnace is respectively heated to 200~300 DEG C；
2) it carries out melting and the foundry returns is first added when melting furnace temperature is 700 DEG C~750 DEG C, sequentially add described
Aluminium ingot and silicon metal, are quickly stirred, and load melting aluminum alloy melt is made；
3) it skims to aluminum alloy melt surface, and takes out the impurity of precipitation to aluminum alloy melt bottom, then to aluminium alloy
Liquid is sampled detection；
4) appropriate magnesium is added according to testing result, and is stirred, forms aluminium alloy；
5) coverture is added into the aluminium alloy, forms the protective layer detached with the aluminium alloy；
6) it stirring melt and it is warming up to 750~780 DEG C again while refining agent is added is refined；
7) after standing 10~15min, melting is completed after examining bath composition qualification.
Further, the steel scrap in 1) is good carbon steel.
Further, the aluminium alloy described in 4) is skimmed again after stirring evenly.
The beneficial effects of the invention are as follows：After being optionally configured as magnesium alloy, high-strength/tenacity aluminum alloy melts the present invention
Sweetening process is simple to operation, by rational furnace burdening sequence and corresponding temperature is controlled, at selection coverture, refining agent
Reason so that aluminium alloy toughness while elevating mechanism intensity reduces unobvious, and whole melting material therefor is of low cost.
