Heating device of flat glass furnace and use method thereof

Abstract

A heating device of a flat glass furnace and a use method thereof. The heating device comprises electrode heating bricks and power supply devices; the number of the electrode heating bricks is even, and all the electrode heating bricks extend out of inner walls of pit wall bricks of the furnace; and each power supply device communicates with each two electrode heating bricks, after the corresponding power supply device is energized, the two corresponding electrode heating bricks heat glass metal in the furnace under the action of joule heat to form a set of heating unit, and the furnace is divided by multiple sets of heating units. The use method of the heating device comprises the step of pushing the electrode heating bricks into the furnace intermittently to make distance d between an end surface of each electrode heating brick and an end wall of each corresponding pit wall brick always larger than 0 mm. Not only is the problem that the joule heat and the temperature on the pit wallbricks are too high solved, but also heat of the electrode heating bricks is effectively used, meanwhile, loads of an external power supply device needed by the furnace are reduced, the electrode heating efficiency is improved, and the production requirements are met.

Description

technical field [0001] The invention belongs to the field of flat glass production, in particular to a heating device for a flat glass kiln and a method for using the same. Background technique [0002] During the operation of the electric-assisted melting furnace used for flat glass, the end faces of the electrode heating brick and the pool wall brick are on the same straight line during the furnace design and furnace masonry process, but as the production progresses, the electrode heating brick The consumption rate of the pool wall brick is different from that of the pool wall brick. The process requires that the electrode heating brick be advanced so that its end face is flush with the end face of the pool wall brick to stabilize production. [0003] Since the consumption rate of the electrode heating bricks is greater than that of the pool wall bricks, in many cases the end faces of the electrode bricks and the end faces of the pool wall bricks on both sides form a "conc...

AI Technical Summary

Problems solved by technology

[0003] Since the consumption rate of the electrode heating bricks is greater than that of the pool wall bricks, in many cases the end faces of the electrode bricks and the end faces of the pool wall bricks on both sides form a "concave" shape, so that the Joule heat generated by the electrode heating bricks during the heating process can not only heat The other part of the glass liquid acts on the wall bricks around the electrode bricks, causing a partial loss of energy consumption and accelerating the loss rate of the wall bricks
