Design and Range of Application of Slot Bushings with Volumetric Orifice Fields

摘要

A design of a slot bushing with a volumetric field has been developed, which allows to produce continuous fibers from melts with difficult processing characteristics in order to produce fibers with better operating characteristics. The operability of the design was confirmed when solving two problems of special technological complexity.1. 400-and 800-orifice bushings for production of continuous fibers from the basalt melt have been developed and recommended for manufacture.2. The process of production of continuous fibers from standard glass using 2400-orifice bushing with perforated plates instead of orifice tips without air cooling, has been realized for the first time.
