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.degree.-820.degree. 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.degree.-750.degree. 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.
