Mullite Refractory Castable Supplier

As we know, mullite a kind of high quality refractory material. The mullite refractory castable is stable in function, convenient in construction and suitable for various industrial kilns. Zhengzhou Rongsheng Kiln Refractory Co.,Ltd. Is a professional refractory material manufacturer with over 20 years of production experience. For refractories, know a lot about. The following is to introduce the mullite refractory castable features.

Mullite refractory castable using high quality mullite and composite superfine powder as the main components. As we all know, natural mullite crystals are elongated needle-like and radiate in clusters, and are often used to produce high-temperature refractories. It is widely used as thermal barrier coating in composite materials, wide application. However, natural mullite is very rare, so
it is usually synthesized by sintering or electrofusion.

Mullite refractory castable features:

1. It is suitable for working lining or heat insulation lining of many kinds of flame furnace and other industrial kilns to realize high temperature and energy saving.

2. High strength, small unit density;

3. This series of refractory castable can be used in the roof, wall and door of industrial kiln. The structural weight is reduced by more than 30% compared with ordinary low cement castable. Effectively eliminate structural broken brick, collapse and other hidden dangers;

4. With high quality porous mullite as aggregate, with a variety of micro powder, dispersant. Low thermal conductivity, good thermal insulation effect. Compared with ordinary castable, the heat loss of kiln can be reduced by 25%~25% and fuel can be saved by 10%.

5. The construction is simple, can not only the whole site pouring, but also can shape any shape prefabricated assembly installation.

Mullite refractory castable can be used in petrochemical industry tubular heating furnace, light diesel oil, atmospheric pressure and pressure furnace, sulfur recovery device, industrial furnace door, fire hole, hole lining and other parts. Welcome to consult!

The mullite refractory castable becomes corundum mullite castable when added to corundum. To tight corundum, mullite as aggregate. The castable is made of white corundum powder, Al2O3 powder and mullite powder. It has the common advantages of corundum castable and mullite castable.

As an important part of castable, lightweight mullite aggregate has a very important effect on the performance of castable. So the choice should be made carefully. Appropriately increasing the critical particle size of aggregate is beneficial to enhancingthe compressive strength of mullite refractory castable. But if the critical granularity is too large, it will construction performance of the material is adversely affected.
