ABSTRACT:
A process and apparatus for converting a stream of desilized and desulfurized pig iron into steel plates of unlimited length. A spray caster is employed utilizing a substantially cylindrical heat-absorbing target surface and a projector rotatable about a vertical axis substantially co-axial with the axis of the cylindrical target surface. A non-oxidizing atmosphere is maintained about the projector and within the space surrounded by the target surface. A pulverulent oxide, chosen from the class consisting of mill scale, iron oxide, the oxide of an alkaline metal which completely evaporates at the temperature of the molten pig iron, the oxide of a desired alloying metal and combinations thereof, is injected into the molten stream of pig iron. The molten stream of pig iron is caused to flow vertically upon the projector, as the projector is rapidly rotated. The projector converts the molten metal stream into a stream of particles having a solid, plastic state and projects the stream of particles against the target with such kinetic energy that the stream of particles impinge upon and become welded to similar particles previously projected against the target surface to build up the steel plate. The steel plate is continuously withdrawn from the target surface.
