Description
Technical field
The utility model relates to a kind of dedicated annealing kilns of float glass, belong to float glass technolog field.
Background technique
The forming process of float glass is completed in the molten tin bath for being passed through protective gas.Melten glass is from tank furnace
It continuously flows into and swims on relatively denser tin liquor surface, under the action of gravity and surface tension, glass metal is in tin liquor
Spread out, shakeout on face, formed smooth upper and lower surface, hardening, it is cooling after drawn upper transition roller table.The roller turn of roller tables, glass
Glass band pulls out molten tin bath and enters annealing kiln, and annealed, cutting just obtains float glass product.
At present in the production process of float glass, wherein annealing kiln be in floatation glass production line connect tin groove forming and
Glass cold-end cutting carry an important equipment, the effect of annealing kiln be exactly by glass tape by pull-out molten tin bath when temperature, press
The process gradually to cool down is required according to annealing process, glass tape is gradually cooled down by annealing kiln in order to cut and carry.If
Temperature then needs suitably heating and soaking lower than annealing ceiling temperature when glass tape enters annealing kiln;If glass tape enters annealing
Temperature is higher than annealing ceiling temperature when kiln, then needs suitably cooling and heat dissipation.
Current float glass lehr have following defects that 1), the glass plate that comes out in molten tin bath by annealing kiln into
Mouth is to prevent the high temperature heat in molten tin bath from interfering the annealing in annealing kiln hence into annealing operation is carried out into annealing kiln at present
Operation is usually provided with check apron in the entrance of annealing kiln, and the check apron is made of thermal insulation board, and the effect of check apron is exactly to stop this
A little huge heats enter annealing kiln, separate outside air with furnace air.The check apron at work, relies primarily on itself and glass
Plate infinite approach can separate the heat outside annealing kiln in this way and enter annealing kiln, guarantee that glass presses lehr attendant in annealing kiln
Skill requires operation;But the drawbacks of this check apron, is: to guarantee that heat insulation, the check apron infinitely connect with glass plate to greatest extent
Closely, if this makes the thickness of glass plate change, that is, need to adjust the position height of check apron in time, this easily influences float glass process
The continuous production of glass;If do not adjusted, the annealing operation effect of annealing kiln will be will affect, to influence float glass
The quality of production.
2), current annealing kiln is different in the temperature of different zones, usually presses according to the direction that glass plate advances
It is successively reduced according to the temperature gradient set.Usually inside control annealing kiln each regional temperature be arranged side on a glass or
The cooling water pipe of lower section, by the parameters such as the initial water temperature of cooling water, flow, flow velocity inside control different location cooling water pipe from
And control the temperature in each region inside annealing kiln;But in the thicker float glass of some thickness of production, due to float glass
Thickness it is thicker, and the thermal coefficient of float glass itself is lower, when this makes float glass be annealed in the annealing kiln,
The cooling water pipe is straight type structure, and the temperature difference around the cooling water pipe is usually no more than 2 DEG C, and the float glass process that thickness is thicker
For glass plate since the heat dissipation at intermediate position is slower, the temperature difference between the temperature and edge at in-between position can even reach 22
DEG C or more, this easily causes Float Glass Surface compression chord, and inside is by tensile stress, thus easily float glass is caused to bend,
Influence the quality of production of float glass.

Temperature is 5 ~ 10 DEG C high;It is discharged after the completion of the cooling water heat exchange of 4th subregion 5b2 by the second drainpipe 58.Due to described
Three round tubes 51 are located at the lower section at the middle part of float glass 1, and second Taper Pipe 52 is located at the lower section of 1 edge of float glass, and the
The position of two Taper Pipes 52 keeps its spacing between the edge of float glass 1, with float glass 1 increasing, also
It is to say, closer to the edge of float glass 1, the lower cooling mechanism 50 is poorer to the cooling effect of float glass 1, this to float
The middle part of method glass 1 is more by heat exchange cooling, and edge cooling is few.Wherein, the mutually symmetrical knot in two sides of the second vertical clapboard 55
Structure, the excellent heat conductivity ability of the second vertical clapboard 55 avoid generating excessively high temperature so that the temperature at 1 middle part of float glass is close
Difference.The heat-proof quality that second diaphragm plate 56 and third erect baffle 59 also makes secondary two 5a of heat transfer zone, third subregion 5b1, the 4th point
There are the apparent temperature difference between area 5b2, so as to reduce mutual interference.
In above process, due to the cooperation between upper cooling mechanism 40 and lower cooling mechanism 50, float glass 1 is added
Middle part by heat exchange cool down it is more, and edge cooling lack, the temperature difference between the edge and middle part of float glass 1 is at 4 ~ 7 DEG C, phase
For existing up to 22 DEG C or more of the temperature difference, float glass 1 is not susceptible to be bent, so that the quality of production of float glass 1
It is protected.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
