Problems solved by technology

The disadvantage of this method is that the shaped brick will shorten after a period of time, so that the width of the glass plate is difficult to meet the requirements
A certain amount of creep deformation will cause uneven thickness distribution of flat glass and force the replacement of forming bricks

Embodiment Construction

[0030] Figures 6a, 6b, and 6c are three-dimensional, front view, and A-A cross-sectional schematic diagrams of an embodiment of this patent. The molten glass enters the forming groove of the forming brick from the inlet pipe 601 of the forming brick 60. The forming groove is composed of a groove bottom surface 602, two side walls 603a and 603b required by a certain curved surface shape, and the forming brick also has two symmetrical surfaces 604a and 603b. The V-shaped body 604 of 604b, the inlet end assembly 605a, the distal end assembly 605b and the supporting body 606 along the length direction in the middle of the shaped brick are formed, and these structures are integrated. The inlet pipe 601 is inside the inlet end assembly 605a, on the inlet end assembly 605a there is a guide wall 607a for molten glass and a support surface 608a for supporting shaped bricks, on the distal end assembly 605 there is a guide wall 607b for molten glass And the support surface 608b used to s...

Abstract

The invention discloses a controlling method of deforming shaping brick due to high-temperature crawl in the flat glass manufacturing course through downward overflow technique, which comprises the following parts: inlet pipe to transmit shaping brick into fusing glass, shaping groove with two walls and certain curved bottom, V-shaped structure to flow fused glass downwards from two sides of shaping groove and inlet end composition with inlet end guide wall and shaping brick support face, wherein the support bulk integrates shaping brick, which controls crawl deformation under high temperature effectively.

Description

technical field [0001] The invention relates to a shaped brick that is deformed by controlling high-temperature creep in the method of producing flat glass using the downward overflow process. This shaped brick weakens the gravity and shape of the shaped brick at high temperature by fixing the middle support block of the overflow brick from the upper part. The pressure generated by the molten glass in the tank on the shaped bricks acts on the shaped bricks, thereby controlling the amount of high temperature creep deformation of the shaped bricks. Background technique [0002] The production of flat glass by the underflow method is one of the recognized basic technologies. In 1967, US Patent No. 3,338,696 introduced the technology of producing flat glass by the underflow method in detail. The content of this patent is incorporated by reference in the present invention for the purpose of introducing the technical background in detail. Figure 1a is a schematic diagram of the p...
