Glass substrate kiln brick provided with fluid flowing hole

Abstract

The invention provided with a glass substrate kiln brick provided with a fluid flowing hole. The brick comprises a brick body (10), a through fluid flowing hole (11) is formed in the brick body (10), a protective pipe (20) for preventing the brick body (10) from being corroded is arranged in the fluid flowing hole (11), the wall of the protective pipe (20) is attached to the wall of the fluid flowing hole (11), and a trumpet structure, whose larger opening faces the internal side, is formed in the inner end of the protective pipe (20). Compared with the conventional protective pipe with equal diameters, the provided protective pipe has the advantages that the circulating flow strength of molten glass in the inlet of the fluid flowing opening is reduced, the flowing state of molten glass is optimized, the washing of molten glass on the corner is reduced, the erosion of molten glass on the inlet of the fluid flowing hole is relieved, the service life of kiln is prolonged, the kiln cost is reduced, the phenomenon that the brick body falls in or is melt into molten glass is reduced, the pollution to the glass is reduced, the refractory stone on the surface of glass substrate is reduced, and the quality and output of glass substrate are both improved.

Description

technical field [0001] The invention relates to the field of glass substrate production equipment, in particular to a glass substrate kiln flow hole brick. Background technique [0002] Flow hole of the glass substrate furnace brick is formed with a flow hole to serve as the connection interface between the glass substrate furnace and the perkin channel. The flow hole of the glass substrate furnace is an important part of the glass furnace, and it is also one of the most severely eroded parts of the glass furnace. The molten glass around the liquid hole is affected by many factors, and the circulation is relatively complicated. The liquid flow hole of the existing glass furnace is mainly made of refractory materials or a platinum pipe of equal diameter is inserted in the flow hole. However, the above two methods cannot slow down the erosion rate of refractory materials around the flow hole. The erosion rate of refractory bricks around the flow hole is 2-10 times that of th...

Problems solved by technology

However, the above two methods cannot slow down the erosion rate of refractory materials around the flow hole. The erosion rate of refractory bricks around the flow hole is 2-10 times that of the wall bricks of the kiln pool. The erosion of refractory bricks around the flow hole is serious. Restricting the service life of the kiln

After the refractory bricks around the flow hole are corroded, they enter the molten glass, changing the composition of the molten glass or forming stones, seriously affecting the quality and output of glass
