The invention discloses a cover plate glass electric
melting furnace and a heating method thereof. An upper
heating furnace body and a lower
liquid storage furnace body form a
melting furnace pool body; a plurality of heating
electrode grooves are formed in the side wall of the lower
liquid storage furnace body uniformly; the heating
electrode grooves are communicated with an inner cavity of the lower
liquid storage furnace body; heating electrodes are arranged in the heating
electrode grooves; a feeding opening and a
flue opening are formed in the side wall of the upper
heating furnace body;the feeding opening and the
flue opening are communicated with an inner cavity of the upper
heating furnace body; a plurality of heating
combustion guns are distributed on the side wall of the upper heating furnace body uniformly; the heating electrodes on the side wall of the lower liquid storage furnace body and the heating
combustion guns on the side wall of the upper heating furnace body perform heating simultaneously, so that the
temperature difference between the surface temperature of cover plate glass liquid and the
internal temperature of the glass liquid is reduced, the glass materials are melted in the melting
pool completely and uniformly, the temperature of the glass liquid in the melting process can keep high enough, excessive
temperature difference between the surface temperature of cover plate glass liquid and the
internal temperature of the glass liquid can be avoided, and the production efficiency of
glass melting is greatly improved.
