Embodiment Construction

[0013] figure 1 , the molten glass flows into the vertical chute (3) through the lip brick (1) under the control of the gate (2), and forms a glass ribbon of required thickness, which is hardened, annealed, and cut to make glass plate.

[0014] Above-mentioned vertical chute (3) is built by laying bricks or stones with graphite material, and can compensate or replace.

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 [0001] Flat glass forming process. Background technique [0002] As we all know, since the float glass process came out in the 1950s, it has become the mainstream process of flat glass production. The forming process of float glass production is completed in a tin bath filled with protective gas (N2 and H2). The molten glass flows continuously from the tank kiln and floats on the surface of the tin liquid with high relative density. Under the action of gravity and surface tension, the glass liquid spreads and flattens on the tin liquid surface to form a flat upper and lower surface, hardens and cools Afterwards, it is led to the transition roller table. The rollers of the roller table rotate, and the glass ribbon is pulled out of the tin tank and enters the annealing kiln. After annealing and cutting, the flat glass product is obtained. Compared with other forming methods, the float method has the following advantages: It is suitable for high-efficiency ma...
