Combined refractory brick for easy connection and high temperature resistance

Abstract

The invention discloses a combined refractory brick for easy connection and high temperature resistance, which comprises a first firebrick body, one side of the first firebrick body is connected witha grooved stone, the inner of the grooved stone is provided with a first flagstone which is matched with the inner groove, one side of the first flagstone is provided with a fixed connecting fixing plate, one side of the fixing plate is fixedly connected with the second firebrick body, the first firebrick body is provided with a number of first through holes , and the the second firebrick body isprovided with a number of second circular through holes. The beneficial effect: when the first flagstone is placed inside the groove wall of groove stone, there will be a gap between them, filling upthe gap with mortar plays a fixed connection role between the first firebrick body and the second firebrick body, inserting the insert block into the groove makes the connection between the first firebrick body and the second firebrick body more fixed, and providing an aerogel filling layer and a refractory fiber filling layer makes the first brick body and the second brick body more heat resistant.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a combined refractory brick which is easy to connect and has high temperature resistance. Background technique [0002] Fire bricks are referred to as fire bricks, which are refractory materials with a certain shape and size. According to the preparation process, they can be divided into fired bricks, unfired bricks, electric fused bricks and refractory insulation bricks. According to the shape and size, they can be divided into standard bricks. Bricks, ordinary bricks and special-type bricks can be used as high-temperature building materials and structural materials for construction kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. [0003] The application number is CN201620600889.1 refractory brick. The patent mentions that the outer surface of the refractory brick body is connected wit...
