Mullite High Alumina Insulating Brick

White Lightweight Mullite Insulation Brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.

White Lightweight Mullite Insulation Brick are mainly made of bauxite clinker, combined with clay as raw materials, mixed with binders and sawdust.

In order to improve product performance, industrial alumina, corundum, sillimanite, kyanite, and silica are added The powder can be produced with bulk density above 0.4g/cm3. Al2O3 content and bulk density are different, the highest operating temperature is also different, usually 1250-1350 ℃, some up to 1550 ℃

Production process:

White Lightweight Mullite Insulation Brick includes five parts: preparation of foaming agent, preparation of foam slurry, molding, drying and firing.

(1) Preparation of foaming agent.

(2) Modulation of foam mud.

(3) Forming.

(4) Dry.

(5) Firing.

Features:

1. High porosity

2. Small bulk density

3. Low thermal conductivity

4. Small heat capacity

5. Good thermal insulation

6. Lightweight

Compared with dense refractory bricks, White Lightweight Mullite Insulation Brick have the following advantages:

(1) With low heat storage and high thermal efficiency, it can speed up the turnover of intermittent operation kilns, improve production efficiency, reduce fuel consumption and save energy.

(2) Low thermal conductivity, which can reduce the thickness of the furnace wall and roof, reduce the quality of the furnace body, and simplify the structure of the furnace.

(3) The furnace temperature can become uniform. Conducive to improving product quality.

(4) The temperature outside the furnace is low, which is convenient for operation, improves labor efficiency, and improves labor conditions for kiln installation and discharge.

Application:

1. Quenching furnace

2. Annealing furnace

3. Box type electric furnace

4. Small heat treatment furnace such as pit electric furnace

5. Tunnel Kiln

6. Roller Kiln

7. Hot air stove of blast furnace

8. Coke oven and other large kilns.

White Lightweight Mullite Insulation Brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
