After calcination at high temperature, sillimanite transforms to mullite and free silica. Generally use the firing process and production of high temperature mud casting method. Its physical and chemical properties are better than those of aluminum bricks, the refractoriness is 1770~1830 degrees, and the load softening point is 1500~1650 degrees centigrade. The utility model is mainly used for the forming of a liquid hole in a glass furnace, a lining of a blast furnace, a furnace throat and a ceramic industrial kiln tool.
Sillimanite brick is made of sillimanite minerals by high temperature firing or mud casting prepared the good properties of refractory brick.
1 、 high temperature resistant abrasion resistant coating;2, sillimanite refractory fireball;3, styrene kaolin - sillimanite insulation refractory products;4. High strength unshaped refractory material is used for building high temperature kiln;5 、 rare earth composite silicon carbide material;6, a composite insulation high-temperature refractory coating;7 、 refractory castable with high temperature self strengthening effect.
