METHOD FOR PRODUCING METALLIC FIBERS OF MELT Russian patent published in 2005 - IPC

FIELD: metallurgy, namely methods for making metallic fibers that may be used for manufacturing composite materials.

SUBSTANCE: method comprises steps of feeding in vertical plane stream of melt metal from nozzle of feeder onto rotating cooled surface; forming on said surface from layer of melt metal discrete liquid structures of metallic fibers; cooling fibers until their crystallization; before feeding stream of melt metal, setting its temperature in range (1.04 x t - 1.18 x t), where t - crystallization temperature of melt metal. Metallic fibers are formed by two stages. At first stage liquid structures of metallic fibers are moved at rate 0.5 - 148 m/s on cooled surface. At second stage metallic fibers are subjected to percussion cooling on ribbed surface of outer disc-type cooled crystallizer at cooling rate in range 3/3 - 25.7.

EFFECT: production of metallic fibers with possibility of increasing range of their fineness at different phase content.
