Brief Introduction of Lightweight Mullite Insulation Brick

Lightweight mullite thermal insulation brick is a kind of thermal insulation brick. It is a refractory material made of refractory clay or other refractory raw materials. Mullite thermal insulation brick is white in color and can directly contact the flame. Hot blast stove top, blast furnace body, and bottom, glass melting furnace regenerator, ceramic sintering kiln, dead corner lining of petroleum cracking system, etc.

Size of Lightweight Mullite Insulation Bricks

Regular lightweight mullite insulation bricks measure 230 x 114 x 65mm.

Lightweight mullite insulation brick model

The models of our common lightweight mullite insulation bricks are JM23, JM26, JM28, and JM30. The difference between them is mainly the content of aluminum oxide and iron oxide. Coefficients and thermal expansion rates are different.

Features of lightweight mullite insulation bricks

1. Low thermal conductivity, good heat insulation effect;

2. Low heat fusion, due to low thermal conductivity, mullite series lightweight heat insulation bricks accumulate little heat energy, and the energy saving effect is obvious in intermittent operation;

3. The content of impurities is low, and it has a very low content of oxides such as iron and alkali metals. Therefore, the refractoriness is high, and the high aluminum content makes it maintain good performance in reducing atmosphere;

4. High compressive strength in a hot state;

5. Accurate appearance and size, speed up the masonry, reduce the amount of refractory mud used, ensure the strength and stability of the masonry, thereby prolonging the life of the lining;

6. It can be processed into special shapes to reduce the number of bricks and joints.

The above are some introductions to the size, model, and characteristics of lightweight mullite insulation bricks. I hope it can be helpful to everyone. As a manufacturer of lightweight mullite insulation bricks, Xinhongji Refractory can also customize them for you according to your needs.
