METHOD FOR STABILIZING A COLUMN OF MOLTEN MATERIAL |
摘要 |
An apparatus for stabilizing a flow of a viscous material, such as a molten glass or glass ceramic material in a tube or rod forming process is disclosed. The apparatus comprises a stabilization member through which the molten glass is passed after leaving the nozzle of a forming vessel. The stabilization member is positioned a finite distance below the nozzle. The column of viscous material is supported by a wall of the stabilization member, or by a gaseous film disposed between the column and the stabilization member. A method of stabilizing the flow of viscous material after it leaves the nozzle during a drawing process is also disclosed.
