Abstract
The invention relates to a new aluminum alloy smelting process, which comprises the following processes: 1, carrying out a feeding process: (1) adding non-remelting recycled scrap and remelting recycled scrap, (2) adding pure aluminum, (3) adding an aluminum-silicon interalloy, (4) uniformly stirring after melting, and (5) adding Mg at a temperature of 680-700 DEG C; 2, refining: (1) carrying out argon gas refining, (2) standing for 12-15 min, and (3) skimming; 3, carrying out modification, wherein adopting a strontium long-term modifier to carry out modification; and 4, pouring according to casting process requirements. With the process, a material cost is reduced by about 10% compared to the original cost, the material is not limited by the alloy material market, and normal production performing is effectively ensured.
Description
Technical field
The present invention relates to a kind of aluminium alloy smelting novel process.
Background technology
Aluminum alloy casting is produced, and generally is to cast with the finished product aluminum alloy materials of outsourcing.The use-pattern of this material, because of the material composition requires to be subjected to the restriction of market condition than higher, wherein if the proportioning of a certain single-element just can't be purchased qualified kinds of goods undesirable, promptly might delay production.
Summary of the invention
The purpose of this invention is to provide a kind of aluminium alloy smelting novel process.
The technical scheme that adopts is:
The aluminium alloy smelting novel process is characterized in that comprising following technological process:
1, charging technology:
(1) foundry returns of the foundry returns of remelting and remelting not;
(2) fine aluminium;
(3) aluminium silicon master alloy;
(4) stir after the fusing;
Add Mg in the time of (5) 680～700 ℃;
2, refining:
(1) argon gas refining;
(2) leave standstill 12-15 minute;
(3) skimming;
3, rotten:
Adopt the strontium long-acting alterant to go bad;
4, pour into a mould by the casting process requirement.
Adopt technology of the present invention, the cost of material reduces approximately 10% than original, and is not subjected to the restriction in alloy material market, has effectively ensured normally carrying out of producing.
Embodiment
The aluminium alloy smelting novel process specifically comprises following technological process:
1, charging technology:
