Regular hexagon all-electric melting tank furnace for melting medium-alkali glass

Abstract

The invention provides a regularly hexagonal all electric melting furnace for melting medium-alkali glass. The regularly hexagonal all electric melting furnace comprises a furnace, molybdenum electrodes arranged on the wall of the furnace, bottom molybdenum electrodes arranged on the bottom of the furnace, and furnace flow hole molybdenum electrodes. The molybdenum electrodes on the wall of the furnace are distributed on three symmetric side faces of the wall of the furnace; three layers of the molybdenum electrodes are arranged; and four upper layer electrodes, two medium layer electrodes and one lower layer electrode are arranged on each side face of the wall of the furnace. The three-layer electrode structure is adopted; the medium layer electrodes are respectively arranged below the space between the upper layer electrodes; and the stable voltage relation between the upper layer electrodes and the medium layer electrodes makes the electric lines between the medium layer electrodes effectively support the electric lines between the upper layer electrodes, simultaneously avoids the unreasonable situation that the electric lines between two layers of electrodes squeeze aside the electric lines between one layer of electrodes, and reduces the erosion of resistant material.

Description

technical field [0001] The invention relates to a regular hexagonal all-electric melting pool furnace for melting medium-alkali glass, especially the electrode distribution of the regular hexagonal full-electric melting pool furnace for melting medium-alkali glass. Background technique [0002] Compared with alkali-free glass, medium-alkali glass has a higher content of alkali metal ions and lower resistivity of glass liquid, so it is more suitable for electro-melting. Electro-melting uses molybdenum electrodes to electrically heat the glass liquid. The surface of the material forms a cold top, and the electrical efficiency is high. up to 85%. [0003] The arrangement of electrodes on the furnace wall, the electrode spacing and the power distribution of electrodes on each layer should meet the requirements of the area melting rate and volume melting rate of the furnace. Unreasonable electrode arrangement and power distribution will lead to unreasonable power lines. Reasonab...

[0003] The arrangement of electrodes on the furnace wall, the electrode spacing and the power distribution of electrodes on each layer should meet the requirements of the area melting rate and volume melting rate of the furnace. Unreasonable electrode arrangement and power distribution will lead to unreasonable power lines. Reasonable distribution makes it difficult to control the temperature of the kiln
