ABSTRACT:
An improvement in the process and apparatus for converting molten metal, especially steel, into a finished product by first converting the molten metal into thin layers which are superimposed on one another while hot and pressure welding the layers into a unitary body that is particularly adapted for hot or cold shaping into a final size and shape, with the advantage of accelerating the cooling of the molten metal and obtaining the improved grain structure and more nearly uniform distribution of alloying ingredients obtainable from rapid solidification of the molten steel to a solid, comprises forming several separate layers from a common heat of molten metal, simultaneously or successively pressure welding utilizing the layers into a unitary body in a single pressure welding station, in contrast to methods of and apparatus for producing a product from several layers requiring a separate casting unit for each separate layer or thickness and also requiring a pair of pressure rolls for each separate added layer or thickness in the finished product.
