Description
Technical field
The present invention relates to field of glass production technology, more particularly to a kind of melting furnaces for TFT glass.
Background technology
TFT glass category " high boron high-aluminum alkali-free " glass, the boron aluminium silicon of boron oxide content 8~12% in the composition of TFT glass
The problems such as silicate glass, its glass melting temperature and forming temperature are very high, and boron volatilizees and easily produces split-phase, layering when founding.
The glass melting temperature of Boroalumino silicate glasses is higher than common float glass glass melting temperature more than 170 DEG C, and generally use total oxygen is combustion-supporting
The thermoelectricity Hybrid Heating being combined with electrofusion melts mode, but the volatility of boron is up to 7~10%, cause that density is lighter two
Silica is gathered in glass metal top layer, this Silicon-rich matter not only fusing point height more infusibility, and viscosity is big, wherein also have accumulated a large amount of
Microbubble be difficult to discharge.There is the glass of silicon dioxide layer must be strictly controlled by fusing for these, otherwise in melting furnaces
In fully and completely disappeared even across multiple high temperature circulation convection current is also difficult, striped and microbubble etc. are finally formed in glass plate
Defect, this TFT glass for reaching optical glass grade to quality requirement are completely unacceptable.In production TFT glass usually
The defects of there is also due to striped and microbubble and have a strong impact on the yields of glass.
Chinese utility model patent《Vertical cold-top melted boron-silicon float glass double combined full electric melting furnace》, Authorization Notice No.

The volatilization of boron in melting furnaces is thus greatly reduced, its volatility is typically only 1~2%.But All Electric Melting Furnace also has it certainly
The defects of body：(1) the vertical fusing mode of electric melting furnace is unfavorable for the exclusion of the microbubble in glass metal；(2) it is complete to produce high borosilicate
Electric melting furnace maximum-norm is usually no more than 30 ton days, and otherwise kiln temperature uniformity is affected, and can also produce striped etc. and lack
Fall into；(3) when slightly not at that time, the uniformity of product is just a greater impact, and product is qualified for electrode arrangement or temperature schedule in kiln
Rate is low.

As shown in Figure 1 to Figure 2, the melting furnaces for TFT glass of the present embodiment, including：The cold top all-electric melting set gradually
Kiln 100 and depositing reservoir 200；
The bottom of the cold top All Electric Melting Furnace 100 is provided with dog-hole 300, and the port of export of the dog-hole 300 and one erect
The lower end connection of the increased channel 400 directly set, the upper end of the increased channel 400 and the charging aperture 110 of the depositing reservoir 200 connect
It is logical；
The top of the cold top All Electric Melting Furnace 100 is provided with the charging aperture 110 added for TFT glass batches, the cold top
The inside of All Electric Melting Furnace 100 is provided with multiple kiln portions electrode 120；
The inside of the depositing reservoir 200 is provided with electrode 210 and multiple flame heat guns 220 in multiple ponds, the clarification
Pond 200 is provided with the exhaust opening 201 for flue gas discharge, and all flame heat guns 220 are arranged at the depositing reservoir 200
Top；
Along flow direction of the glass metal of the TFT glass in the depositing reservoir 200, the pond of the depositing reservoir 200

The rear of pole 210.
In the present invention, cold top All Electric Melting Furnace 100 forms cold top using vertical Melting Mechanism, cold top All Electric Melting Furnace 100
Afterwards, because head temperature is relatively low, therefore cold top All Electric Melting Furnace 100 radiating substantially reduces, and the thermal efficiency significantly improves, while low temperature
Inhibit the volatilization of volatile matter；
Shaping liquid stream in existing vertical cold-top melted boron-silicon float glass double combined full electric melting furnace is from upper vertical current
Downwards, the removal of bubbles process and in glass metal is flotation from bottom to top, i.e. the effusion process of bubble and shaping glass
The flow direction of glass liquid stream is unfavorable for the discharge of bubble on the contrary, add the stroke and resistance of bubble floating in glass metal；It is and existing
Vertical cold-top melted boron-silicon float glass double combined full electric melting furnace cold roof construction because top glass liquid temperature degree is low, viscosity
Greatly, also it is unfavorable for the effusion of bubble, therefore existing vertical cold-top melted boron-silicon float glass double combined full electric melting furnace smelter
Skill actually also limit the clarification of microbubble in glass metal.
Melting furnaces using the present invention are to separate the fusion process of the glass metal of TFT glass and clarification, homogenization process, TFT
