Abstract (en)
A method of refining grains of primary silicon of a hypereutectic aluminium-silicon alloy which is cast into an ingot by introducing a melt of the alloy into a casting mold from a holding furnace which accommodates the melt. The method comprises adding a grain-refining agent containing phosphorus continuously to a flow of the melt from the holding furnace to the casting mold through a passage communicating with the furnace and the mold, and thereby refining the grains of the primary silicon upon solidification of the melt in the casting mold.
