ELECTRICAL MELTING OF SOLIDIFIED GLASS IN MELTING UNITS

摘要

The solidified glass is melted by first melting (with a burner) the glass around an electrode in the melter chamber entry to the throat so that the molten glass is conductive. Electric energy is then supplied between this electrode and the first electrode in the throat to melt the glass between these electrodes. Electric energy is then successively applied between the electrode in the melter chamber and each subsequent spaced electrode in the throat until all the glass in the submerged throat is molten. Used in restarting a melting furnace which has been shut down contg. a full glass charge.
