Abstract
A system for casting pig iron is provided. The system has a runner, a tundish, and a mold receiving molten iron in a superheated state, and a feed system positioned adjacent to one of the runner, the tundish, and the mold. The feed system contains solid particles having a chemical composition substantially similar to the molten iron, and is positioned to direct a stream of the solid particles the one of the runner, the tundish, and the mold such that the stream of solid particles mixes with the molten iron. A method is also provided. A stream of molten metal is provided in a superheated state during a casting process, and is mixed with a stream of solid particles such that the solid particles at least partially melt with molten metal to increase a volume of the molten metal without substantially changing a chemical composition of the molten metal.
