Description
Technical field
The utility model is related to a kind of devices melting sample for experimental glass, suitable for FPD is melted in laboratory
The various glass products of industry application.
Background technology
With the continuous development of flat panel display device technology, the glass of FPD industry application (protect by ITO electro-conductive glass
Protect glass, glass substrate) not only quantity required it is increasing, performance requirement is also higher and higher.Especially glass substrate is tablet
One of display industry key foundation material and a kind of maximum glass of dosage.Meet needs of the market to high-performance glass,
It first must be by developing new material side in the constantly molten sample in laboratory, analysis, test, and technique being provided for material side's industrialization
The technological parameter of characteristic and critical material and equipment Design.However, due to newly developed glass technology content height, strain point is continuous
Raising, fusion temperature are also continuously improved, and manufacture difficulty is increasing, and this glass is melted in laboratory using general sample-melting stove
Glass, it is difficult to ensure to melt the quality of sample, obstacle is brought to laboratory R＆D work, in this case, improve sample-melting device,
The needs that higher performance glassware melts sample can be met.
Utility model content
The utility model is intended to by improving sample-melting device, to improve the molten sample quality of glass.
Concrete scheme be related to it is a kind of for experimental glass melt sample device, the device by furnace body, lifting platform, mounting table,
Crucible, heating rod, stirring rod, motor form, crucible are placed on mounting table, and mounting table is fixed on the table top of lifting platform, lifting
Platform can move up and down, and stirring rod is fixed on the top of furnace body, its upper and lower position and whipping process, heating rod are controlled by motor
It is fixed on inboard wall of furnace body.
It is precious metal platinum or platinum-rhodium alloy material, outer layer that crucible for melting sample, which uses inside and outside double-layer structure, internal layer,
It is inside and outside to use two kinds of materials for pyroceram fibre cotton, it has the advantage that：The part contacted with glass metal is met without dirt
Dye, heat safe platinum or platinum-rhodium alloy material ensure the needs of high temperature melting sample, while the refractory material of outer layer plays heat preservation
The effect of insulating supporting, moreover it is possible to which the oxidation for preventing platinum product extends the service life of crucible.Crucible equipped with platinum or
The lid that platinum-rhodium alloy makes helps to be kept the temperature when glass heats fusing.
The utility model increases agitating device, and the addition of the device plays good work for the uniformity of glass
With stirring rod is fixed on the top of sample-melting stove body, its upper and lower position and Stirring are controlled by motor.It was tested relative to the past
For the molten sample of this no device of room, solving the molten sample of laboratory crucibles, viscosity has big difference up and down, uneven components
Phenomenon makes laboratory melt the glass sample of high quality, is conducive to the accuracy for improving molten sample test analysis.
Glass melt viscosity is very high, and bubble is difficult to exclude, and the uniformity of glass ingredient is difficult to ensure, increasing agitating device has
Conducive to diffusing into one another, melting between the melt of different component, the bubble in glass metal rises, to eliminate the striped in glass,
Glass metal is promoted to reach uniformity in chemical composition.
Special crucible is placed on mounting table, and mounting table is formed by laying fireproof bricks, and mounting table is fixed on lifting platform, is risen
Drop platform descends track thereon by button control, its advantage is that ensure that sampling setting-out is free, while the table top of lifting platform is close to stove
Body makes furnace body have good seal.
Description of the drawings
Fig. 1 is experimental glass sample-melting device schematic diagram.
Wherein：1- motors；2- stirring rod；3- crucibles；4- Si-Mo rods；5- furnace bodies；6- mounting tables；7- lifting platforms.
Specific implementation mode
The utility model will be further described with reference to the accompanying drawings and examples：
Laboratory pours into load weighted batch within molten sample crucible 3, and crucible is made of inside and outside two kinds of materials, internal layer material
Material is made of precious metal platinum or platinum-rhodium alloy, pure because the molten sample clarifying temp of the newly developed glass in laboratory is close to 1700 DEG C
The fusing point of platinum is at 1768 DEG C, so selecting pure platinum or platinum-rhodium alloy material as crucible internal walls, ensure that glass melts sample
It needs.The outer layer of crucible wraps up for pyroceram fibre cotton, can prevent platinum or platinum-rhodium alloy ingress of air from aoxidizing,
The effect that heat preservation support and insulation is also acted simultaneously for crucible, extends the service life of crucible.Earthenware equipped with batch
Crucible is placed on mounting table 6, and mounting table is placed on the table top of lifting platform 7, starting switch, and lifting platform rises within furnace body 5, lifting
Platform is fitted closely with furnace body, ensures leakproofness of the furnace body in molten sample.Furnace interior is equipped with several heating element Si-Mo rods 4,
Ensure that melting sample temperature reaches 1650 DEG C or more.Clarifying temp reaches 1670 DEG C, and higher reaches 1690 DEG C.It melts sample and is different from laboratory
Producing line melts sample, and producing line calciner area is larger, and the space for excluding bubble is more abundant, then takes certain melting technology and increase
Some auxiliary devices can effectively exclude bubble and control other defects, and laboratory melt sample be in the crucible of very little into
Row, the space for excluding bubble is limited, and the utility model increases agitating device, by motor 1 control stirring rod 2 mixing speed with
Stirring rod stretches into the position in glass metal, is stirred to glass metal by stirring rod 2, has both solved laboratory crucibles and has melted sample
The phenomenon that upper and lower viscosity has big difference, uneven components, and be conducive to the discharge of the bubble in glass metal, contribute to laboratory to melt
The glass sample for going out high quality is conducive to the accuracy for improving molten sample test analysis.Stirring rod by heat safe platinum family or its
Alloy material is made.
