AVOIDANCE OF NICKEL SULFIDE STONE IN A GLASS MELTING PROCESS

摘要

Nickel sulfide stones are avoided during the melting of glass batch materials in a glass melting furnace by electrically maintaining oxidizing conditions near the bottom of the upstream portion of the melting furnace at a location upstream from the establishment of a spring zone. In one embodiment an anode is located against the bottom pool of the molten glass.
