Abstract:
1. An improved process of homogenizing of already molten material of dielectric type, the molten material including inhomogenities in the form of corrosion melt cords, the improved process comprising: introducing the molten material from a melting area of a furnace to a refractory channel of a forehearth or to a working end of the furnace; substantially shielding the molten material inside a shielded casing; exposing the molten material inside the shielded casing to microwave radiation passing through at least one waveguide, the microwave radiation being directed toward a lower part of the refractory channel or toward the working end of the furnace and having a frequency of 0.1 to 20 GHz, the molten material having a viscosity of 10 maintaining the viscosity value until dissolution of inhomogenities in the form of corrosion melt cords in the molten material is achieved; and insulating a waveguide outlet.
