METHOD AND APPARATUS FOR DIRECTLY FORMING CONTINUOUS GLASS FILAMENTS

摘要

An in-line system converts raw, unrefined glass-forming material directly into continuous glass filaments. The system includes a reinforced melting assembly with electrically conductive melting and reinforcing members. The melting and reinforcing members are connected to a transverse melting member and lie in a plane parallel to the flowing material. This expands the melting and refining zone to the height of the melting and reinforcing members, thereby improving the quality of the filaments. The melting and reinforcing members also prevent sagging of the assembly during high temperature operation. The outermost melting and reinforcing members reduce or eliminate bypass flow of un-refined or un-homogenized material around the melting assembly, further improving quality.
