Process for producing aluminium-silicon alloy with content of silicon of 2-22% by mass

Abstract From the Canadian patent

The present invention relates to metallurgy of nonferrous metals and alloys and, more particularly to a, process for producing an aluminum-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 aluminiumsilicon 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 …
