Product details


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
