METHOD OF PRODUCTION OF ALUMINUM-AND-SILICON ALLOYS Russian patent published in 2005 - IPC

FIELD: technology of production of alloys on base of aluminum and silicon; production of aluminum-and-silicon alloys.

SUBSTANCE: proposed method includes introduction of molten silicon into aluminum melt, correction of melt and pouring in molds; metal-containing wastes of aluminum and/or silicon process are subjected to treatment with melt of aluminum or its alloy; amount of wastes is determined by the following formula: M_w=(0.077-0.23)M_Si/M_Al(M_Si+M_Al), where M_w is amount of wastes, kg; M_Al is mass of molten aluminum, kg; M_Si is mass of molten silicon; 0.077 is minimum proportionality coefficient; 0.23 is maximum proportionality coefficient. Then, molten silicon is added to melt.

EFFECT: enhanced efficiency of process.
