METHOD FOR PRODUCING ALUMINUM-SILICON ALLOY WITH A SILICON CONTENT OF 2 TO 22 MASS

摘要

The method consists, in its first variant in dissolving a 20-50 mm fraction of crystalline silicon in liquid aluminium at a temperature of 780-820 DEG C while continually mixing the ingredients in a reverberatory furnace until obtaining an alumino-silicon melt and while simultaneously introducing, under the level of the melt, a 0,3-1.0 mm fraction of crystalline silicon with a jet of an inert gas. The second variant of the method consists in the joint dissolving of the mentioned fractions of silicon in the liquid aluminium at a temperature of 780-820 DEG C while continually mixing the ingredients in the reverberatory furnace, the 0.3-1.0 mm fraction of silicon being pressed together with barium chloride and a flux before dissolving. The alloy may be used in the automobile and tractor industry, as well as for production of consumer goods.
