Rosewool Clay Insulation Bricks to Sri Lanka
The characteristics of mullite heat insulation bricks: high temperature resistance, high strength, small thermal conductivity, remarkable energy saving effect, is a new type of energy-saving refractory material; suitable for ceramic roller kiln, electric porcelain and arts and crafts porcelain shuttle kiln, stepping type Heating furnace etc. In recent years, prefabricated tunnel kilns have been used in the wall material industry.
In recent years, the working face of the prefabricated tunnel kiln has also adopted lightweight high-alumina or lightweight mullite; Design indicators of strength and resistance to air erosion. Practice has proved that it is best to choose refractory oxide hollow ball products with a pore size of less than 0.6mm and foam production as the kiln lining. Because these materials have high compressive and flexural strength, their service life can be greatly improved, such as oxidation The compressive strength (~10MPa) and service temperature (16000°C) of aluminum hollow sphere products are much higher than other lightweight refractory materials.
