Refractory block and glass furnace

Abstract

The invention belongs to the technical field of refractory blocks, and particularly relates to a refractory block and a glass furnace. The refractory block comprises a refractory block body, and the refractory block body is formed by splicing a plurality of arc-shaped refractory slabs; a mounting groove is formed in the inner wall of one side of each arc-shaped refractory slab, and a clamping plate is arranged on the other side of each arc-shaped refractory slab; a plurality of square inserting holes are uniformly formed in the inner wall of each mounting groove and are formed in the verticaldirection of the inner wall of the mounting groove; a plurality of square inserting blocks are uniformly arranged on the outer side wall of each clamping plate, and the plurality of square inserting blocks are inserted into the plurality of square inserting holes; square inserting cavities are formed in the upper end surface of one side of each arc-shaped refractory slab, and the square insertingcavities are communicated with the plurality of square inserting holes which are vertically formed; square inserting strips are inserted into the square inserting cavities in an extruding manner, andsynchronously penetrates through square communicating cavities. The locally damaged or broken refractory block body can be conveniently maintained and replaced, so that the service life of the refractory block body is prolonged.

Description

technical field [0001] The invention belongs to the technical field of refractory blocks, in particular to a refractory block and a glass melting furnace. Background technique [0002] Glass is an electrical conductor at high temperatures. The molten glass contains alkali metal sodium and potassium ions, which have electrical conductivity. When an electric current passes through it, Joule heat is generated, and if the heat is large enough, it can be used to melt the glass. [0003] Among refractory products, it is well known that the refractory blocks used in the construction of glass melting furnaces are different from the refractory blocks used in refining kilns represented by converters for steel manufacturing. [0004] The patent discloses a kiln, a refractory construction method and a refractory block. The patent application number is 2010800215662. The plurality of refractory blocks respectively have: a hexagonal working part exposed on the central side of the kiln. ...

AI Technical Summary

Problems solved by technology

[0005] Although the above can prevent the shedding of refractory blocks when the kiln is tilted; when most of the existing refractory blocks are integrally formed, and then installed in the inside of the glass melting furnace, when the integral refractory block is subjected to impact force and local When damaged or broken, it is necessary to replace and repair the refractory block as a whole, which will reduce the service life of the glass melting furnace
