Abstract (en)

[origin: WO8802410A1] The method consists in charging in the form of a cone, crystalline silicon on the hearth of a reverberatory furnace, pouring the liquid aluminium into the bath of the furnace at a temperature of 780-820C while continually mixing the aluminosilicon melt by means of a jet formed of the same melt, which is directed to the base of the cone of the charged silicon at a speed of the jet, along its axis, of 0.5-0.8 m/sec; simultaneously with the start of the mixing the temperature of the melt in the bath of the furnace is cooled down to 670-750C and mixing is continued at this temperature. The alloy may be used in the automobile and tractor industry, as well as for production of consumer goods.
