ABSTRACT:
A mold assembly for continuous casting has a plurality of open-ended molds. The mold assembly further has a cooling member which is common to all of the molds and cooperates with each mold to define one or more cooling passages therewith. The cooling member, which is provided with one or more pairs of coolant inlet and outlet bores, is in the form of a cooling jacket or in the form of a back-up plate depending upon whether the molds are tube molds or plate molds. The mold assembly is rotatably mounted on a mold table having a casting location at which a mold is positioned during a casting operation. A coolant supply and coolant discharge conduit are arranged in the mold table adjacent the casting location. In operation, one of the molds of the assembly is positioned at the casting location with the remaining molds being in standby positions. At least one pair of the coolant inlet and outlet bores in the cooling member is aligned with the coolant supply and discharge conduits in the mold table. Molten metal is introduced into the mold to form a continuously cast strand. When the mold is to be changed, the introduction of molten metal into the mold is terminated. The trailing end of the strand is withdrawn from the mold, the supply of coolant to the mold is discontinued, and the mold assembly is rotated to bring another mold into the casting position. In this manner, substitution of one mold for another may be accomplished rapidly and without removing the supply vessel for the molten metal.
