Abstract
The utility model discloses an all-electric furnace, which comprises a flame space, an upper melting tank, a lower melting tank, transition bricks, a throat and an uptake, wherein the flame space is positioned at the upper part of a furnace body and is provided with a feed inlet, the upper melting tank is positioned below the flame space, the lower melting tank is positioned below the upper melting tank, the transition bricks are installed on the inner walls of the two melting tanks, the throat is positioned in the lower melting tank, the uptake is arranged on the lateral surface of the furnace body, and main melting electrodes are arranged on the transition bricks; and the all-electric furnace is characterized in that more than one secondary electrode is arranged at the bottom of the furnace body. In one embodiment of the utility model, one secondary electrode is arranged near the throat. In another embodiment of the utility model, two secondary electrodes are arranged near the throat at a certain distance. The utility model has the advantages that more than one secondary electrode is arranged at the bottom of the furnace body, a loop is formed from the secondary electrode and the main melting electrodes through a glass liquid, and the glass liquid which is not melted well can be forced to reflow after the loop is electrified, thereby the flow molding of the glass liquid which is not melted well is avoided, and the product quality is improved.
Description
(1) technical field
The utility model relates to a kind of all-electric melting furnace, is used to produce high-boron-silicon glass, makes the glass metal can forced refluence by setting up sub-electrode, overcomes because of the Electric Field Distribution inequality causes glass defect, has improved product quality.
(2) background technology
Existing all-electric melting furnace, comprise the flame space that has charge door that is arranged in upper of furnace body, be positioned at the flame space below last melting tank, be arranged at following melting tank below the melting tank, be installed in two melting tank inwalls transitional brick, be positioned at the dog-hole of time melting tank and be arranged on the increased channel of body of heater side, all be furnished with main consumable electrode on the described transitional brick.There is following problem in this kind structure: body of heater inside has the part glass metal that fusing is not good and directly enters moulding stream, makes its inner calculus, air-flows etc. of producing, and causes poor product quality.
(3) summary of the invention
The technical problems to be solved in the utility model has provided a kind of all-electric melting furnace, is used to produce high-boron-silicon glass, makes the glass metal can forced refluence by setting up sub-electrode, overcomes because of the Electric Field Distribution inequality causes glass defect, has improved product quality.
In order to solve the problems of the technologies described above, the utility model is realized by following measure:
A kind of all-electric melting furnace, comprise the flame space that has charge door that is arranged in upper of furnace body, be positioned at the flame space below last melting tank, be arranged at following melting tank below the melting tank, be installed in two melting tank inwalls transitional brick, be positioned at the dog-hole of time melting tank and be arranged on the increased channel of body of heater side, all be furnished with main consumable electrode on the described transitional brick, it is characterized in that: described bottom of furnace body is provided with the sub-electrode more than 1.
