PROCESS FOR PRODUCING METALLIC FIBERS Russian patent published in 2006 - IPC B22F9/10 B22D11/06 

FIELD: metallurgy, namely manufacture of metallic fibers, wool, fiberboard.

SUBSTANCE: process comprises steps of feeding metal to dispersing zone; forming from metal surrounded by dynamic gas layer discrete particles of melt metal and simultaneously converting dynamic layer to gas-vapor mixture. Discrete particles of melt metal are formed during two stages. At first stage at least one electrode is broken by electric arc method for creating flow of discrete particles of metal; breaking formed metal particles due to their striking at rate 500 - 1100 m/s with surface of rotating dispersing disc by angle 4 - 90° relative to rotation plane. At second stage formed discrete micro-particles of metal are agglomerated till similar size on surface of rotating disc dispersing member due to acting upon them simultaneously by means of gas-vapor mixture and mechanical force field of rotating dispersing disc. Formed particles are converted to liquid structures of metallic fibers due to acting upon them by means of mechanical force field of rotating dispersing disc. Then fibers are cooled on surface of coaxial rotating crystallizing disc provided with unit for controlling temperature of its working surface. Crystallized fibers are removed from disc working surface.

EFFECT: possibility for automatic calibration of discrete fiber particles, stabilized production process.
