Problems solved by technology

The gas flow, pressure, and purity are different, and the inlet position is different; resulting in incomplete protection of the glass surface, easy to form quality defects such as tin spots, stains, and tin scratches on the glass surface. For thin float glass, such surface quality defects cannot meet user needs

Embodiment 1

[0009] Embodiment 1: as figure 1 As shown, the outlet flow of the air storage tank 1 is adjusted at 200L / h through the adjustable flowmeter 5; the pressure is controlled at 0.6Mpa to ensure stable gas supply; The flow rate of the flowmeter is controlled at 35L / h, and then it is connected to iron, copper or stainless steel metal pipes through the outlet of the branch pipeline. The inner diameter of the metal pipe 4 is controlled at 10mm and can be bent; finally, it is symmetrically inserted into the transition roller table through the bendable metal pipe .

Embodiment 2

[0010] Embodiment 2: as figure 1 As shown, adjust the outlet flow of air storage tank 1 at 800L / h; control the pressure at 0.8Mpa to ensure stable gas supply; then divide it into four adjustable flowmeters for flow distribution, and the flow rate of each adjustable flowmeter is controlled at 150L / h, and then connect iron, copper or stainless steel metal pipes through the outlet of the branch pipeline. The inner diameter of this metal pipe is controlled at 12mm and can be bent; finally, it is symmetrically inserted into the transition roller table of the annealing kiln through the bendable metal pipe.

Embodiment 3

[0011] Embodiment 3: For the glass with more defects, the gas supply point can be increased, and the outlet flow of the gas storage tank 1 can be adjusted at 1300L / h; the pressure is controlled at 1.1Mpa to ensure the stable gas supply; and then divided into six via adjustable flowmeters For flow distribution, the flow rate of each adjustable flowmeter is controlled at 180L / h, and then connected to iron, copper or stainless steel metal pipes through the outlet of the branch pipeline. The inner diameter of this metal pipe is controlled at 15mm and can be bent; figure 1 The four curved metal pipes shown are symmetrically inserted into the transition roller table, and the other two are symmetrically arranged at the annealing kiln.

[0012] In the process of gas supply, to prevent leakage and contamination of gas by impurities such as water and oxygen, it is required that the gas supply pipeline must be tight. In production, depending on the quality of the glass, for example, ther...

Abstract

The invention discloses a application method for sulfur dioxide gas in ultra-thin glass product, which comprises: regulating total flow quantity and pressure by the outlet pressure-reduction device on gas holder to control flow quantity within 120~1500L / h and pressure within 0.1~1.2MPa; allocating flow quantity by four or six adjustable flowmeter every with flow quantity within 20~200L / h; connecting with metal pipe by branch pipe, and inserting symmetrically the metal pipe into transition roller plant of annealing kiln. This method solves shortcoming in float glass production with simple operation.

Description

Technical field [0001] The invention belongs to a method for using sulfur dioxide gas, and mainly relates to a method for using sulfur dioxide gas in ultra-thin glass production. Background technique [0002] Currently, sulfur dioxide gas is used at the transition roll table in float glass production. The gas flow, pressure, and purity are different, and the inlet position is different; resulting in incomplete protection of the glass surface, easy to form quality defects such as tin spots, stains, and tin scratches on the glass surface. For thin float glass, such surface quality defects cannot meet user needs. Contents of the invention [0003] The purpose of the present invention is to provide a method for using sulfur dioxide gas in the production of ultra-thin glass, which can reduce the formation of defects on the surface of ultra-thin float glass without adversely affecting the gas and atmosphere of the tin bath. [0004] The object of the present invention can be r...
