Abstract
A non-turbulent, level pour feeding of molten metal into a continuous-casting mold is provided through inlets formed in heat insulated blocks positioned at opposite shorter sides of the mold for casting large rectangular aluminum ingots. The heights of inlet passages are designed to clean impurities from molten metal. The longer sides of the mold are cooled to a higher level than the shorter sides.
Claims15
A continuous casting mold for vertical casting, having a horizontal inlet through the side of the mold for introducing molten metal, said inlet being defined by a body having a passageway therethrough, means for insulating said body from adjacent chilled portions of the mold, an interior surface of the mold against which the molten metal is initially to be frozen to form an ingot, said surface extending around the mold beneath said inlet-forming body and upwardly on both sides of said inlet-forming body, means to chill said interior surface of the mold, and means to apply coolant directly to the ingot as it emerges from the mold, said means to chill said interior surface of said mold for freezing the ingot initially along the upper interior surface of the mold on the sides of said inlet-forming body, while freezing the ingot at a lower level along said surface beneath said body.
A continuous casting mold for vertical casting, having two relatively long sides opposite each other and two relatively short sides opposite each other, a horizontal inlet passageway through each of the opposite shorter sides for entry of molten aluminum into the mold, each of said inlet passageways being formed in a body, means for insulating said bodies from adjacent chilled mold portions, mold faces extending around the interior of the mold, against which the molten metal in the mold is initially to be frozen, means to chill said mold faces, and means to apply coolant directly to the ingot emerging from the mold, said means to chill said mold faces for freezing the ingot initially along the chilled mold faces of the longer sides of the mold at a level close to the top level of the molten metal in the mold on the sides of said inlet forming bodies, while freezing the ingot initially at a lower level along the shorter sides of the mold beneath said inlet forming bodies.
