METAL SECTOR FOR BOTTOM OF GLASS MELTING FURNACE, AND GLASS MELTING FURNACE

摘要

Disclosed is a plurality of metal sectors separately arranged so as to form a bottom of a glass melting furnace. The metal sectors comprise: an upper surface made from a bottom surface of the glass melting furnace; a lower surface opposite to the upper surface; and a plurality of lateral surfaces coming in contact with the upper surface and the lower surface. An electrical arc suppression structure is provided at a part or an entire part of an edge in which the upper surface or the lower surface comes in contact with each lateral surface. The electrical arc suppression structure can be a curved edge or an insulating coating layer. The electrical arc suppression structure enables stable operation of the glass melting furnace.
