Andalusite based Caslable Applied to Iron & Steelmaking, Cement Production, Glass Industry, CFBC Boiler and Insulating Materials

摘要

Andalusite is a natural refractory raw material belonging to silico-alumina group with chamotte, mullite, bauxite. Andalusite is differentiated from other silico-alumina raw materials by the following points: firstly, andalusite doesn't need any thermal treatment like other materials doing; secondly, it will be transformed to mullite(87%) and glass-amorphous silica(13%) between 1000°C - 1450°C.
