Abstract: A melt drag metal strip casting system of the type wherein molten metal is delivered from a supply of the molten metal into contact with a chill surface at a casting station and the chill surface is driven for movement in a path past the casting station at a predetermined linear rate to quench and withdraw a continuous strip of metal from the molten metal supply, the strip having a bottom surface adhering to the chill surface and an unsolidified top surface as it is withdrawn from the molten metal supply, includes a top roll adjustably mounted above the chill surface and spaced therefrom by a distance substantially equal to the thickness of the strip desired with the top roll in contact with the unsolidified top surface of the strip, with the temperature of the top roll surface in contact with the unsolidified top surface of the strip being maintained at a level which will not solidify the top surface of the metal being cast.

Abstract: Disclosed are process and apparatus for use in the direct casting of metal strip from molten metal deposited on a moving chill surface from a tundish having a floor, opposed upwardly extending sidewalls, an end wall, an open outlet opposite the end wall with the open outlet extending substantially the full width of the tundish between the sidewalls, and an inlet for providing a flow of molten metal into the tundish from a source of molten metal. Flow diverters within the tundish divide the flow of molten metal into a plurality of separate streams and divert one of the streams in the direction of each sidewall and for recombining the diverted streams into a composite stream flowing toward the outlet. Flow diffusers diffuse the molten metal flowing through the tundish to provide molten metal of substantially uniform temperature across the width of the tundish at the outlet.

Abstract: An improved melt drag metal strip casting apparatus and process in which molten metal is delivered from a supply thereof into contact with a cooled casting surface driven at a predetermined linear rate to quench and withdraw a continuous strip of metal from the molten metal supply. An air knife is employed to direct an elongated narrow jet of gas into contact with the top surface of the strip and with the molten metal supply as the strip is withdrawn to impart the desired shape and finish to the top surface of the strip and to control the amount of liquid metal adhering to the top surface as it is withdrawn to thereby control the thickness of the strip.
