Abstract The present invention relates to metallurgy of non-ferrous metals and alloys and, more particularly, to a process for producing an aluminium-silicon alloy with a content of silicon of 2 to 22% by mass. The process comprises charging crystalline silicon onto the sole of a reverberatory furnace so that the charged crystalline silicon has a cone shape, casting liquid aluminium into the furnace bath at 780°-820° C. and agitation of the resulting aluminium-silicon melt by means of a shaped jet of the same melt; the melt jet is directed into the base of the cone of the charged crystalline silicon at a speed of the jet along the axis thereof of from 0.5 to 0.8 m/s; simultaneously with the beginning of agitation the melt temperature in the furnace bath is lowered to 670°-750° C. and agitation of the melt is effected at this temperature. The alloy can be used in the automobile industry, tractor manufacture in the production of consumer goods.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
A process for producing an aluminum-silicon alloy with a content of silicon of 2-22% by mass comprising charging crystalline silicon onto the sole of a reverberatory furnace, the charged crystalline silicon having a cone shape; casting liquid aluminium onto the sole of said reverberatory furnace to form a molten bath with the silicon at a temperature of from 780° to 820° C.; agitating the resulting aluminum-silicon melt by a shaped jet of the same melt, said melt jet being directed into the base of the cone of the charged crystalline silicon; and casting the resultant melt into a mold to produce an aluminum-silicon alloy in a solid state.
Claim 2
Dependent Claim
108 words
