ABSTRACT:
A method and apparatus for of starting the continuous casting of a first metal in the mold of a continuous casting machine, in which a molten second metal having a melting point lower than that of the first metal is first introduced into the mold of the casting machine at a temperature substantially below the melting point of the first metal and in which the introduction of the second metal is discontinued and the casting of the first metal is begun after cooling of the mold has caused the second metal to form a solidified plug within the mold and while the cooling of the mold continues. The apparatus includes means for the sequential casting of the second and first metals in a casting machine while the casting machine is being cooled and the method allows metals of very high melting point, such as steel, to be continuously cast without damaging the mold or creating undue danger to the operator.
