Industrial television brick

Abstract

The invention discloses an industrial television brick. The industrial television brick comprises a body brick and a cushion brick, wherein the body brick is of a cuboid structure, the back of the body brick is an inclined surface, and the top of the back inclines towards the front of the body brick; a through hole is formed in the body brick, communicates with the front and the back of the body brick, and is perpendicular to the inclined surface of the back of the body brick; the part, close to the back of the body brick, of the through hole is a straight hole; the part, close to the front ofthe body brick, of the through hole is a horn mouth; the large end of the horn mouth faces the surface of the front of the body brick; the cushion brick is arranged at the bottom of the body brick; the front end of the cushion brick extends to the outer side of the front of the body brick from the bottom of the body brick; and a groove is formed in the top of the extending part of the cushion brick and is located under the end of the horn mouth. According to the invention, the industrial television brick avoids defects of a glass substrate caused by falling of coagulum into molten glass; an industrial television lens is placed in the inclined straight hole, so the condition of molten glass can be observed at a better angle; and the horn mouth can provide a larger observation visual anglefor the industrial television lens.

Description

technical field [0001] The invention belongs to the field of glass substrate manufacturing and relates to an industrial TV brick. Background technique [0002] During the manufacturing process of the glass substrate, the glass frit should be melted, clarified and homogenized in the kiln to provide qualified and homogeneous glass liquid for the next process. The molten glass melted in the kiln is alkali-free high alumina borosilicate glass, and the glass products are mainly glass substrates for flat panel display. [0003] The glass substrate must not have any defects before it is used in flat panel display glass, including bubbles, stones, precious metal defects, heterogeneous glass particles and other defects. Among them, stones (refractory stones) basically come from the erosion, evaporation and condensation of refractory materials in the kiln. Since the periphery of the industrial TV lens is made of stainless steel, it often causes iron stones on the glass substrate, and...

Problems solved by technology

Among them, stones (refractory stones) basically come from the erosion, evaporation and condensation of refractory materials in the kiln. Since the periphery of the industrial TV lens is made of stainless steel, it often causes iron stones on the glass substrate, and the high-temperature flow of industrial TVs passes through. The lens holes of industrial TV bricks often flow back into the glass liquid, causing glass substrate defects
