ABSTRACT:
This invention sets forth an improved method of continuously casting a metal filament or fiber from molten liquid metal. The filament is formed by forcing the molten metal from a melt pot through an orifice and solidifying the molten metal jet into a filament while it is moving in a cooling atmosphere. As the solid filament moves with respect to the gas atmosphere, the gas by friction with the surface of the filament will exert a force on the filament, either acceleration or deceleration depending on whether the gas is flowing with a velocity greater or less than the filament velocity. The invention sets forth parameters defining the relations that must exist between the filament velocity and cooling gas velocity which give rise to acceleration and deceleration forces and whose magnitudes determine the formation of continuous filament or fibers.
