METHOD FOR PRODUCING GLASS FIBER

摘要

METHOD FOR PRODUCING GLASS FIBER A process for making glass fibers is provided comprising supplying a stream of molten glass to a rotating rotor (50); discharging said glass through orifices in said rotor (50) as a plurality of primary streams; and attenuating said primary streams into fibers, said rotor (50) being fabricated from a superalloy by a process comprising hot isostatically pressing the superalloy material sufficient to substantially increase the high-temperature service capability of the rotor (50); and electropolishing said rotor (50) to at least partially remove the sharp edges and discontinuites in the orifices (55) to reduce or eliminate the amount of break-in time otherwise required.
