Abstract
The invention discloses a molten bath of a glass kiln, which comprises a bath wall and a bath bottom; a right-angle corner is formed between the bath wall and the bath bottom; a right angled triangle brick is arranged at the right-angle corner; two right-angle sides of the right angled triangle brick are respectively clung to the bath wall and the bath bottom; and both ends of an inclined edge are respectively and closely contacted with the bath bottom and the bath wall. The molten bath has the advantages of effectively changing glass liquid flow and reducing the retention time of glass liquid at the corner so as to lead glass liquid not to have the time element of devitrification, thereby avoiding the occurrence of glass devitrification phenomenon, substantially reducing the defect of glass devitrification, improving product quality and increasing finished product ratio.
Description
Technical field
The present invention relates to found forming field, is a kind of glass furnace molten bath specifically.
Background technology
As shown in Figure 1, the turning that forms between 2 at the bottom of the pool wall 1 in present glass furnace molten bath and the pond is the right angle corner structure, is provided with square block 3 at the right angle corner place.Existing structure is prone to the crystallization phenomenon in glass production, yield and quality is had very big disadvantageous effect.The crystallization phenomenon of glass is bigger to the negative impact of the silicate industry transparent glass quality of production.Glass is a kind of supercooled liquid, and it has the long-range unordered constitutional features of melt.From the thermodynamics viewpoint, the interior of glass state material can be higher than the crystalline state material, thereby its structure is a metastable phase.Driven mechanics viewpoint sees that the increase of melt cools medium viscosity is very fast, so that the particle diffusion does not reach the essential condition that the speed that forms lattice is glass state material formation.
Vitreum is in the thermodynamic instability state, and the trend of the structural state variation that therefore total oriented free enthalpy is lower is until becoming stable crystalline state.Glass heats arrives a certain temperature range, and keeps time enough, makes it the conversion condition in dynamic, and the particle in the glass crystallization phenomenon occurs with regard to possibility recast ordered arrangement so.One is 845 ℃～1058 ℃ to the temperature range of devitrification of glass by test determination.Temperature is approaching at the bottom of crystalline range and the glass furnace pond, and glass metal is detained after the right angle corner place forms the dead angle for a long time, causes glass to produce crystallization.
Summary of the invention
Goal of the invention:, the object of the present invention is to provide a kind of glass furnace molten bath that can solve the crystallization problem in the float glass process in order to overcome the deficiencies in the prior art.
Technical scheme: in order to solve the problems of the technologies described above, a kind of glass furnace of the present invention molten bath, comprise at the bottom of pool wall, the pond, form right angle corner at the bottom of described pool wall and the pond, the place is provided with the right-angle triangle brick in described right angle corner, the two ends that two square edges of described right-angle triangle brick are attached to pool wall, Chi Dishang, hypotenuse respectively respectively with at the bottom of the pond, pool wall closely contacts.
Be 30～60 ° of angles at the bottom of the hypotenuse of described right-angle triangle brick and the pond.
Be 45 at the bottom of the hypotenuse of described right-angle triangle brick and the pond.
The length of every square edge of described right-angle triangle brick is 150～300mm.
Beneficial effect: compared with prior art, advantage of the present invention is: can effectively change glass metal stream, reducing glass metal stops around the corner for a long time, make glass metal not possess the element of time of crystallization, thereby avoid the devitrification of glass phenomenon to occur, reduce the devitrification of glass defective significantly, improve the quality of products, improve yield rate.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is a structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of glass furnace of the present invention molten bath, comprise at the bottom of pool wall 1, the pond 2, pool wall 1 and 2 formation right angle corner at the bottom of the pond, the place is provided with right-angle triangle brick 4 in described right angle corner, two square edges of right-angle triangle brick 4 are attached at the bottom of pool wall 1, the pond on 2 respectively, the two ends of hypotenuse respectively with at the bottom of the pond 2, pool wall 1 closely contacts.
2 are 30～60 ° of angles at the bottom of the hypotenuse of described right-angle triangle brick 4 and the pond, preferred 45.
The length of every square edge of described right-angle triangle brick 4 can be determined preferred 150～300mm according to the size in this molten bath and the amount of glass metal.
Adopt the present invention, can effectively change glass metal stream, make can not produce glass metal residence time minimizing around the corner the dead angle, thereby avoid the devitrification of glass phenomenon to occur, reduce the devitrification of glass defective significantly.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
