Abstract
The invention discloses a vertical sliding lead-down forming method for a plate glass chute. The vertical sliding lead-down forming method for the plate glass chute is characterized by comprising the following steps: with a solid material which is low in friction coefficient, high in heat conductivity coefficient, small in expansion coefficient, good in chemical stability, low in permeability and heat-resistant, and has a polishing function as a vertical chute, carrying out vertical sliding lead-down forming on glass metal in a slot, and pulling and leading out a glass tape with required thickness and width.
Description
Technical field
Formed from plate glass technique.
Background technology
As everyone knows, since last century, the fifties float glass technology was come out, the prevailing technology that sheet glass is produced has been become.The moulding process of float glass completes in the molten tin bath passing into shielding gas (N2 and H2).Melten glass continuously flows into and swims in the large tin liquor of relative density on the surface from tank furnace, under gravity and capillary effect, glass metal spreads out on tin liquor face, shakeout, formed upper and lower surface smooth, sclerosis, cooling after drawn transition roller table.The roller turn of roller tables, enters annealing furnace glass ribbon pull-out molten tin bath, through annealing, cutting, just obtains flat glass product.Float glass process compares with other forming method, and its advantage is: be suitable for high efficient production high-quality sheet glass, and as not having, brush line, thickness are even, upper and lower surface is smooth, parallel to each other; The scale of production line is not by the restriction of manufacturing process, and the energy consumption of unit product is low; Finished product utilization ratio is high; Be easy to scientific management and realize mechanize completely, automatization, labour productivity is high; The cycle of working continuously is several years, is conducive to stably producing; Can be some new variety of online production and applicable condition is provided, as coating film glass, cold end surface process etc. when electric float glass process reflecting glass, annealing.
But float glass also has it to be difficult to the shortcoming overcome, such as molding control complex process, the easy oxidation consumption of tin liquor, sheet glass are subject to that tin liquor is polluted, easily caused the damage of glass surface during glass ribbon pull-out molten tin bath, to produce ultra-thin glass very difficult etc.
Summary of the invention
For solving the problem, the invention provides a kind of sheet glass chute vertical sliding motion and draw compacted under method, it is characterized in that: low with a kind of frictional coefficient, thermal conductivity is high, the coefficient of expansion is little, chemical stability is good, rate of permeation is low, the high temperature resistant and solid material with polishing function is as vertical chute, glass metal vertical sliding motion in its line of rabbet joint is drawn compacted under, and drawing goes out the glass ribbon of desired thickness and width.
Be provided with rib in glass ribbon both sides, control the width of glass ribbon with it.
The thickness of sheet glass is controlled by the pulling speed of sheet glass.
In the outside surrounding of above-mentioned glass ware forming chute, be provided with heating or refrigerating unit (not shown in FIG.) along journey, in order to the setting rate of the viscosity and sheet glass that control glass ribbon.
By above-mentioned glass ware forming chute sealing, and be filled with carbonic acid gas, rare gas element or reduction one, in case the high temperature oxidation of above-mentioned solid material.
Above-mentioned solid material is graphite, the crystalline flake graphite that preferably oilness is fabulous.When manufacturing process is ripe in the future, also grapheme material can be adopted.
The usefulness of this sheet glass slip method of forming is: 1, simple, the low cost of manufacture of technique; 2, for the thickness of sheet glass and the control of width easier; 3, materials consumption is low; 4, manufacture ultra-thin glass easy and conveniently.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of one of the embodiment of the present invention.
1. lip tiles in figure, 2. control flashboard, 3. vertical chute, 4. glass ribbon.
Embodiment
In Fig. 1, the glass metal melted, under the regulation and control of flashboard (2), flows in vertical chute (3) through lip tile (1), and forms the glass ribbon of desired thickness, through sclerosis, annealing, cutting, makes sheet glass.
Above-mentioned vertical chute (3) is built by laying bricks or stones with graphite material, and can compensate or change.
Claims (6)
