Description
Technical field
The present invention relates to a kind of float glass field, the particularly a kind of multi-thread float glass production process of a kiln and dress
Put.
Background technology
The forming process of float glass is completed in the molten tin bath for be passed through protective gas, and melten glass is from melting furnaces
Continuously flow into and swim on relatively denser tin liquor surface by runner, in the presence of gravity and surface tension, glass
Liquid is spread out on tin liquor face, shakeout, forming the smooth glass tape of upper and lower surface, and upper transition roller table is drawn after hardening by cooling and pulls out tin
Groove enters annealing kiln, and annealed, cutting obtains finished glass.Because being molded with floating method, referred to as float glass.
Float glass is because its surface smoothness is good, light transmittance is high, high mechanical strength, good chemical stability, it has also become flat board glass
The state-of-the-art production method of glass industry.With continuing to develop for new technology, float glass product apply from traditional architecture glass to
The new fields such as various high added values, the electronics industry of new and high technology, energy-conserving and environment-protective constantly extend.
The arrangement of current floatation glass production line main line both at home and abroad is the line of a kiln one, floatation glass production line main line from
A float glass smelting kiln, card neck, cooling end, molten tin bath, annealing kiln, a cold end are sequentially arranged after going to, often
The quantitative floatation glass production line of bar has the card neck and cooling end of specific size.This arrangement is relatively more suitable for glass rule
Lattice change is few, the production line that tonnage is larger, has the disadvantage that yield rate can be reduced by often changing plate, it is impossible to while producing different-thickness
Glass, high energy consumption when particularly producing ultra-thin glass, quality is difficult to ensure card.And because the glass metal fusing amount of large-tonnage melting furnaces is big,
And the amount of actual single line production ultra-thin glass is smaller, excessive, the surplus of glass metal are generated, so as to cause the consequence of high energy consumption.
The content of the invention
It is an object of the present invention to provide a kind of multi-thread float glass production process of a kiln and device.The invention enables life
Producing line can produce the glass of different-thickness different size with Simultaneous Stabilization, reduce all size glass production cost, moreover it is possible to reduce
The energy consumption of each production line, improves product quality.
Technical scheme：The multi-thread float glass production process of one kiln, it is characterised in that：Produced in large-tonnage melting furnaces

Small, it is 0.6-0.95 to reduce the factor.
In the foregoing multi-thread float glass production process of a kiln, described big path both sides are separately installed with temperature, pressure tune
Save device.
The multi-thread float glass device of a kiln of the foregoing multi-thread float glass production process of a kiln is realized, its feature exists
In：Including large-tonnage melting furnaces, large-tonnage melting furnaces are connected with ultra-thin glass production line through main cooling end, and large-tonnage melting furnaces are also associated with
One or more big path, big path is connected with floatation glass production line, described big path both sides difference through branch's cooling end
Provided with temperature, pressure adjuster.
In the multi-thread float glass device of a foregoing kiln, the melting end of the large-tonnage melting furnaces is connected with card neck, card
Neck is connected with main cooling end, big path respectively；The cross-sectional area amplification of the card neck, amplification factor is 1.05-1.25；Described
The area of main cooling end and branch's cooling end reduces, and it is 0.6-0.95 to reduce the factor.
In the multi-thread float glass device of a foregoing kiln, the melting end of the large-tonnage melting furnaces is connected with card neck, card
Neck is connected with main cooling end respectively, and main cooling end is connected with big path.
In the multi-thread float glass device of a foregoing kiln, the melting ends of the large-tonnage melting furnaces respectively with main cooling
Portion, the connection of big path.
In the multi-thread float glass device of a foregoing kiln, described large-tonnage melting furnaces are more than 500T/D melting furnaces.
Compared with prior art, the present invention by shunting by the melten glass liquid in large-tonnage melting furnaces by supplying a plurality of float glass process
Glass production line is used, so that large-tonnage melting furnaces, which can be stablized, provides low energy consumption, high quality glass specific to large-tonnage melting furnaces
Liquid so that production line can produce the glass of different-thickness different size with Simultaneous Stabilization, reduce all size glass production cost.
Also combined, reduced because melting end fluctuation of operating conditions is to the straight of cooling end using the card neck, big path and cooling end of particular design
Influence is connect, while every production line has a relatively independent cooling end, cooling end is greatly reduced and is back to melting end
Glass liquid measure.Because the length of big path is longer, obtained by the Comprehensive Experiment of many factors, the cross-sectional area of card neck is amplified
(the card neck cross-sectional area of more conventional same floatation glass production line), amplification factor 1.05-1.25, while reducing corresponding
The area of main cooling end and branch's cooling end reduces (the cooling end area of more conventional same floatation glass production line), reduce because
Sub- 0.6-0.95, it is ensured that quality of the glass metal on big path, so that the quality of product is can guarantee that, to provide the production of plurality of stable
