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 grooved 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 grooves in the chill surface being gradually parallel and spaced from one another to provide land regions between adjacent grooves and the strip having a bottom surface adhering to the land regions of the chill surface and an unsolidified top surface as it is withdrawn from the molten metal supply, including a top roll adjustable mounted above the chill surface and spaced therefrom by a distance substantially equal to the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 only 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.
