Problems solved by technology

[0002] Refractory bricks belong to a kind of material in the industrial field. In the existing technology, the domestic refractory brick material is only a layer of refractory layer. Its structure is too simple to meet the needs of production and industry. Most of the refractory bricks are generally made of aluminum Made of earth, kaolin, clay, diatomaceous earth and other materials, it has the property of high temperature resistance, and it will not melt immediately even at 1400°C
[0003] Existing refractory bricks have the characteristics of heat conduction, but their simple structure determines that they are lacking in heat conduction. At the same time, the heat is seriously lost during the transfer process. On the other hand, when the heat is transferred, it is difficult to preserve

Embodiment Construction

[0012] Such as figure 1 As shown, a composite refractory brick includes a brick body, the brick body is rectangular, and the brick body is divided into three parts, which are the outermost refractory material 1, the asbestos mesh layer 3 in the middle layer, and the inner layer Layer of insulation material2. The inner layer insulation material 2 is provided with mullite particles 4,

[0013] The thickness of the asbestos mesh layer 3 is about 3mm--5mm.

[0014] The outermost refractory material 1 is a lightweight high-temperature refractory material.

[0015] The heat first passes through the outermost layer of refractory material 1, and then passes through the asbestos mesh layer 3 to the inner layer of thermal insulation material 2. store it up.

[0016] The combination of refractory material 1 and inner layer insulation material 2 reduces heat loss and promotes efficient use of energy. The asbestos mesh layer 3 in the middle makes heat transfer stable and evenly distrib...

Abstract

The invention relates to a compound firebrick, which comprises a brick. The invention is characterized in that the brick is rectangular, and the brick can be divided into three sections. The outermost layer is refractory materials, the middle layer is asbestos net layer, and the inner layer is thermal insulation materials. Mullite particles are installed in the thermal insulation materials in the inner layer. The invention is capable of reducing the lost of heat and promoting the efficient usage of energy through the combination of the refractory materials and the insulation materials in the inner layer. The asbestos net layer in the middle enables the heat transfer to be reliable and convenient, then the heat is equally distributed, and the local overheating can be avoid, and thus the using life of a furnace wall is extended.
