Continuous casting of ingots

摘要

In the embodiments described in the specification, continuous casting of ingots is carried out by transferring molten metal from a hearth to a mold through one or more flow channels which provide flow paths having a shallow angle to the horizontal and which terminates adjacent to the surface of the molten metal in the mold so that the vertical velocity component of the stream of molten metal flowing into the mold is minimal and the horizontal velocity component is low. In one form, the hearth surrounds the mold, providing four shallow-angle flow channels uniformly spaced around the periphery of the mold to avoid unilateral introduction of the molten material into the mold.
