Abstract
The present invention discloses an application method for sulfur dioxide gas in ultra-thin glass production, which is characterized in that total flow and pressure are regulated through regulating an outlet pressure reducing device of an air storage tank; the flow is controlled from 120 to 1500L/h, and the pressure is controlled from 0.1 to 0.2MPa; the flow is distributed through four or six adjustable flowmeters, and flow of each adjustable flowmeter is controlled from 20 to 200L/h; a branch pipeline outlet is connected with a metal pipeline, and the metal pipeline is symmetrically inserted into an annealing furnace and a transition roller. When used for producing ultra-thin float glass, the present invention better solves the problems of tin spots, dirty spots, tin scratching, etc., on glass surfaces and has the advantages of simple and convenient operation.
Description
Technical field
The invention belongs to the using method of sulfur dioxide gas, relate generally to the using method of sulfur dioxide gas in a kind of thin float glass production.
Background technology
At present, use sulfur dioxide gas in the float glass at transition roller platform place.Gas flow, pressure, purity have nothing in common with each other, and feed the position difference; Cause the protection of glass surface not exclusively, form mass defects such as tin point, stain, tin scuffing easily at glass surface, for the thin float glass that is mainly used in the photoelectron industry, this type of surface quality defect can not be met consumers' demand.
Summary of the invention
The purpose of this invention is to provide the using method of sulfur dioxide gas in a kind of thin float glass production, can reduce the formation that causes the thin float glass surface imperfection, and can not have a negative impact molten tin bath gas, atmosphere.
Purpose of the present invention can realize by the following technical solutions: regulate total flux and pressure by regulating gas holder outlet reliever, dominant discharge is at 120～1500L/h; Pressure-controlling is at 0.1～1.2Mpa, carry out assignment of traffic through four or six adjustable under meters then, the flow control of each adjustable under meter is at 20～200L/h, after the branch line outlet connects metallic conduit, the metallic conduit symmetry is inserted into the transition roller platform place of annealing furnace.
Method of the present invention has solved the defectives such as tin point, stain, tin scuffing of glass surface preferably when producing thin float glass, simple, convenient.
Description of drawings:
Accompanying drawing 1 is the synoptic diagram with four air feed branch roads of the present invention.
Shown in the figure: 1, gas holder, 2, tracheae, 3,5, adjustable under meter, 4, metal tube.
Embodiment
The accompanying drawings specific embodiments of the invention.
Embodiment 1: as shown in Figure 1, regulate gas holder 1 rate of discharge at 200L/h by adjustable under meter 5; Pressure-controlling is at 0.6Mpa, and it is stable to protect air feed; Be divided into four then and carry out assignment of traffic through adjustable under meter 3, the flow control 35L/h of each adjustable under meter, after the branch line outlet connects iron, copper or stainless steel metal pipeline, this metallic conduit 4 internal diameters are controlled at 10mm, and are flexible; Be inserted into transition roller platform place by bendable metallic conduit symmetry at last.
Embodiment 2: as shown in Figure 1, regulate gas holder 1 rate of discharge at 800L/h; Pressure-controlling is at 0.8Mpa, and it is stable to protect air feed; Be divided into four then and each and every one carry out assignment of traffic through adjustable under meter, the flow control 150L/h of each adjustable under meter, after the branch line outlet connects iron, copper or stainless steel metal pipeline, this metallic conduit internal diameter is controlled at 12mm, and is flexible; At last by the symmetrical transition roller platform place that inserts annealing furnace of bendable metallic conduit.
Embodiment 3: for the more glass of defective, can increase the air feed point, regulate gas holder 1 rate of discharge at 1300L/h; Pressure-controlling is at 1.1Mpa, and it is stable to protect air feed; Be divided into six then and carry out assignment of traffic through adjustable under meter, the flow control of each adjustable under meter is at 180L/h, after the branch line outlet connects iron, copper or stainless steel metal pipeline, this metallic conduit internal diameter is controlled at 15mm, and is flexible; Wherein four curved metallic conduit symmetries as shown in Figure 1 are inserted into transition roller platform place, and two are symmetricly set on the annealing furnace place in addition.
In the air feed process, prevent to reveal and impurity such as water, oxygen to the pollution of gas, require the supply air line must be tight.Aborning, look the glass quality situation, for example defective more (scuffing, stain, tin point) appears in glass quality, fine setting flow and pressure.In the selection of air feed point position, determine what of insertion point according to the glass quality situation, generally speaking, the both sides symmetry is respectively inserted two small transfer lines under the sheet glass at excessive roller platform place, if it is more that tin point, stain, scuffing appear in glass, then respectively increase by one in annealing furnace both sides symmetry.During use, must keep stable operation, to guarantee the balance of gas flow.
