FIELD: chemistry.
SUBSTANCE: device for continuous fibre manufacture from basalt row material includes feeder containing electrically heated bushing plate with bushing in its bottom part having wall thickness within the prescribed limits. The bushing wall is made of bimetal which thermal conductivity coefficient on the outer side of bushing surface is 2.0-2.5 times as much as thermal conductivity coefficient on the inner side.
EFFECT: providing of temperature uniformity through bushing thickness at melt moving along the channel, enhancing productivity and operation reliability of the device.
