Refractory brick prepared on the basis of refractory material

Abstract

The invention relates to the technical field of refractory brick structures, in particular to a refractory brick prepared on the basis of a refractory material. The refractory brick prepared on the basis of the refractory material comprises a main brick which at least comprises a first shell inside; a first limiting groove is formed in the center of the upper surface of the first shell; a groove is formed in the position, close to the right side edge, of the upper surface of the first limiting groove; a first clamping wall is integrally formed in the position, close to the left side edge, of the upper surface of the first shell; a connecting rod is fixedly connected to the lower surface of the first clamping wall; a lower groove is reserved between the first clamping wall and the first shell; a first core groove is formed in the center of the surface of the right side wall of the first shell; and first heat insulation grooves are formed in the front side and the rear side of the first core groove. Through an arranged brick core and an arranged heat insulation plate, the structural stability of the brick body is improved through the brick core; the problem of expansion and cracking of the brick body caused by continuous high temperature of the refractory brick is effectively relieved; through the heat insulation plate, the heat transfer efficiency can be reduced and the refractory effect can be effectively enhanced; and through the brick core and the heat insulation plate, the overall refractory performance of the brick body can be improved.

Description

technical field [0001] The invention relates to the technical field of refractory brick structures, in particular to a refractory brick prepared based on refractory materials. Background technique [0002] Refractory bricks, referred to as refractory bricks, are refractory materials with a certain shape and size. According to the preparation process, it can be divided into burnt bricks, unfired bricks, electric fused bricks (fused cast bricks), refractory and heat-insulating bricks; according to the shape and size, it can be divided into standard bricks, ordinary bricks, special bricks, etc. It is used as a high-temperature building material and structural material for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures.

AI Technical Summary

Problems solved by technology

[0003] Refractory bricks are formed and calcined by refractory materials to form silicon carbide refractory products, which have good wear resistance and corrosion resistance, high temperature strength, high thermal conductivity, and good thermal shock resistance. However, the existing refractory bricks The connection stability between them is poor, and the connection gap is large, which greatly affects the heat resistance of the refractory bricks. At the same time, continuous high temperature will easily cause the bricks to expand and crack. Therefore, the purpose of the present invention is a refractory brick prepared based on refractory materials. Some refractory bricks have poor connection stability and large connection gaps, which greatly affect the heat resistance of the refractory bricks. At the same time, continuous high temperature is likely to cause bricks to expand and burst.
