Feature
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.
Silimanite brick are mainly used in high temprature furnaces, such as glass melting furnace,etc.
►The main applications are:
Rider arches
Forehearth superstracture
Bushing for rochwool and fiber glass
►Specifications:
Dense structure
Good thermal shock resistance
►Advantages：
Corrosion-resistant
High quality
