Abstract
A device for the continuous casting of thin metal strips includes two parallel spaced rotatable rolls, side walls located at the ends of the rolls and defining with the rolls a casting space for liquid metal, a flat cover disposed above the liquid metal and in the immediate vicinity of the meniscus of the liquid metal so as to form a thermal screen which is so dimensioned as to cover the whole of the surface of the liquid metal. The cover is provided with a refractory lining on the side of the cover facing toward the liquid metal and bearing against the two rolls. This cover forms a thermal screen or shield preventing any surface solidification of the bath of liquid metal from starting. Advantageously, an inert gas may be injected between the meniscus and the cover through the latter.
