Summary

Corning has developed an all-electric glassmelting furnace with a molybdenum lining to protect its refractory walls and bottom from corrosion. The lining provides long life and also allows the refractory to be well insulated. Electrodes immersed through the batch blanket cause rapid melting of these materials. In this manner, energy efficiencies of >85% are attainable. Glass leaving the furnace is sufficiently cooled in a molybdenum pipe to minimize defects resulting from any subsequent refractory contact. This technology is currently being applied in Coming's manufacturing operations and is also being marketed in the glass industry.
