ABSTRACT:
A process disclosed for producing spherical articles or fibers with a specially fixed size from a melt of metal, slag, or flux, by introducing the melt onto the center of a rotating disk through a conduit so as to form a thin film stream of boundary layer on the disk; projecting the thin film stream at a high speed fom the disk periphery into surrounding space to split up the film stream into linear streams; and cooling the linear streams for producing fibers or cooling droplets after further splitting of the each linear stream into droplets for producing spherical particles, with or without parallel or countercurrent gas flow to the linear streams.
