Description
Technical field
The utility model belongs to float glass technolog field, more particularly to a kind of floatation glass production line is filled with molten tin bath
Put.
Background technology
China's plate glass overwhelming majority produces for float glass process forming technique, and float glass process forming technique is to utilize the small melting of proportion
Glass metal is swum in above heavy tin liquor, and melten glass liquid is because of self gravitation, surface tension, lehr rollers drawing gravitation, drawing
Under the collective effect of side machine, the plate glass of required thickness and width is produced；Molten tin bath agent structure is divided into up-down structure, top
For molten tin bath overhead guard, lower part is molten tin bath bottom；Molten tin bath is made of three parts:Input end, molten tin bath body and the port of export (transition roller
Platform).Input end is both the transition position of molten tin bath and melting furnaces, and the port of export is the junction of molten tin bath and annealing kiln, and molten tin bath body is one
The cuboid confined space built up with steel plate and refractory material.
Molten tin bath is the Thermal Equipment of float shaping, and the inside contains the tin liquor of fusing.Due to tin liquor meet oxygen after easily
Tin oxide is generated by oxidation, glass surface is sticked to, causes glass defect, therefore a certain amount of protection gas is usually connected with into molten tin bath
Body, and form in molten tin bath the normal pressure of tens pas, to prevent outside molten tin bath containing aerobic gas into people.Glass metal enters molten tin bath
Complete to shakeout on tin liquor face afterwards, polish through drawing thin or heap is thick to form a continuous glass tape, be full of N all the time in molten tin bath2、H2
Protective gas, to reduce tin liquor oxidation.
Tin liquor is flowed with glass tape direction of advance in molten tin bath, and when glass tape leaves molten tin bath terminal position, tin liquor produces back
Stream, molten tin backflow divide two parts, and a part flows back from the bottom of advance tin liquor, and another part is empty from glass tape and molten tin bath abutment wall brick
Flow back at gap.Since tin channel inlet end and the port of export temperature difference are larger, stronger, the colder molten tin backflow to high-temperature region of molten tin bath edge heat dissipation
When can produce stronger tin liquor turbulent flow, easily produce larger transverse temperature difference.So as to influence the yield rate of glass.
Easily there is following several respects problem in existing molten tin bath in a word, is severely impacted glass quality.
Firstth, melting furnaces atmosphere enters molten tin bath, and entrained sulphion, makes tin liquor volatile quantity significantly increase in melting furnaces atmosphere
Add, and react to form SnS with tin liquor2, reactant agglomerates in the solid interface such as molten tin bath input end or tin groove roof, in specific bar
Light distortion can be caused and the mass defects such as tin is miscellaneous by dropping under part；
Secondth, the outer air of molten tin bath enters in molten tin bath, and tin steam and Sn0 meet oxygen and form SnO herein2, and be adhered on molten tin bath
In portion or front arch, when molten tin bath pressure oscillation or while being shaken by external force drop and cassiterite mass defect formed on metal level;
3rd, the movement of glass tape drives the convection current and reflux of tin liquor, and there are larger horizontal and vertical due to tin liquor
The temperature difference, can so influence the yield rate of glass.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose that a kind of floatation glass production line is filled with molten tin bath
Put.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of floatation glass production line tin groove device, the tin groove device have molten tin bath body；The molten tin bath body
Tin liquor is inside placed with, and floating has glass tape in the top of the tin liquor；The bottom of the molten tin bath body is provided with to reduce
Molten tin backflow, the graphite bar for improving tin liquor convection current；The graphite bar is two to be arranged in parallel；The tin groove device
It is additionally provided with the check apron glass tape and exposed tin liquor face to be separated；The check apron is positioned at ribbon width direction two
Side it is multiple；The distance between the check apron and molten tin bath two sides are 200-500mm.
The check apron has high silica fiber baffle；The high silica fiber baffle upper end is fixed with heat-resisting steel sheet and plate；Institute
The heat-resisting steel sheet and plate stated is bolted on the both sides of molten tin bath top surface.
U-shaped through hole is provided with the graphite bar；The U-shaped through hole is positioned at the more of the latter half of graphite bar
It is a；The distance controlling of the U-shaped through hole is between 1mm to 100mm.
The utility model proposes a kind of floatation glass production line tin groove device, molten tin bath bottom set graphite gear
Bank, effectively reduces the reflux of tin liquor and improves the convection current of tin liquor, and the mass defect of shaping and reduction glass to glass has weight
The effect wanted；
In float glass, to prevent the tin liquor in molten tin bath from polluting glass after being aoxidized, usually it is filled with molten tin bath
Nitrogen and reductive hydrogen, groove is interior to keep micro-positive pressure, reduces tin liquor exposed area and tin liquor vaporization at high temperature amount；The utility model exists
Installing high silica fiber check apron on the basis of original tin groove structure additional, this check apron can separate glass tape and exposed tin liquor face,
So as to avoid SnO2 With the pollution probability of the impurity to glass tape such as SnS, the yield rate of glass is improved.
