Abstract
An apparatus for forming a strip of metal which includes: a tundish for receiving molten metal; a metal delivery nozzle located below the tundish in a position to receive molten metal flowing downward from the tundish; and a pair of chilled rollers, which are capable of being contra-rotated, positioned below the metal delivery nozzle which are adapted to receive molten metal from the metal delivery nozzle into a pool of molten metal formed above the nip of the roller. The tundish is equipped with a series of openings in the base thereof directed toward the metal delivery nozzle through which the molten metal flows, and with an outlet flow control means. The outlet flow control means is a movable plate with apertures therein which substantially coincide with the apertures in the base of the tundish. Means are provided to move the outlet control plate to cause its apertures to go into and/or out of alignment with the apertures in the base of the tundish and thereby regulate the flow of molten metal therethrough. One or more outlet flow control plates can be provided so that flow through all or only a portion of the tundish apertures can be regulated at any given time.
