Abstract:
A continuous casting system for impeding wave formation, said system comprising:a continuous casting mold, said continuous casting mold adapted to receive a flow of molten metal, to contain said molten metal, and to dispense said molten metal for casting, said continuous casting mold comprising interior surfaces, said interior surfaces comprising major interior surfaces and minor interior surfaces, said continuous casting mold having an inner length, an inner width, and an inner height, wherein each said major interior surface is defined by said inner length and said inner height, each said minor interior surface is defined by said inner width and said inner height, and wherein said molten metal forms an upper metal surface; a submerged entry nozzle extending below said upper metal surface, said submerged entry nozzle comprising at least one discharge orifice adapted to dispense said flow of molten metal into said continuous casting mold below said upper metal surface; and at least one surface flow modifier member, each said surface flow modifier having a thickness, a width and a height, each said surface flow modifier further having at least one major face defined by said width and said height, at least one surface flow modifier extending below said upper metal surface, each said surface flow modifier terminating above said at least one discharge orifice, wherein at least a portion of each said surface flow modifier is sufficiently wide enough to substantially span said inner width of said continuous casting mold without a said surface flow modifier touching said interior surfaces below said upper metal surface, each said surface flow modifier vertically disposed between said submerged entry nozzle and a said interior surface of said continuous casting mold such that at least one said major face is substantially orthogonal to said flow of molten metal in said continuous casting mold so as to impede formation of waves in said upper metal surface.
