Silimanite brick is a kind of refractoriness which made by silimaniteand other minerals. And silimanite can be transformed to be mullite under more 1500℃ high temprature.
► Applications
Silimanite brick are mainly used in high temprature furnaces, such as glass melting furnace,etc
► The main applications are:
1,Rider arches
2,Forehearth superstracture
3,Bushing for rochwool and fiber glass
► Specifications
1,Dense structure
2,Good thermal shock resistance
► Advantages
1,Corrosion-resistant;
2,High quality
