FIELD: technological processes.
SUBSTANCE: invention relates to the field of continuous fiber production from melt of basalt rocks and relates to bushing assembly for production of basalt jet for processing of melt into fiber. Bushing assembly for production of continuous fibers from melts of basalt rocks consists of bath for melt pouring, feeder body, filtering mesh, current conductors, bushing plate and draw bushings. At the same time channel of draw bushings in longitudinal section is arranged along exponential dependence of current radiuses of channel on its length. Length of draw bushing channel surface flexure at half of its length makes h=1.0-1.2 from half of holes radiuses sum at the inlet and outlet of draw bushings channel.
EFFECT: increased strength of fiber, reduced consumption of melt for manufacturing of fiber.
