30% Sic High Aluminum Light Weight Castables Refractory Abrasion Acid Resistant
Introduction
Castable refractoriness also has been know as refractory,is a kind of granular and powder material which is made of refractory material of adding some amount of binder.Castable is high fluidity and suitable for the unshaped refractoriness which is formed in the way of pouring.
Compared with other unshaped refractory materials,the castable has more binder and moisture content,better fluidity,so the unshaped refractory material is widely used,the materials and binder can be chosen according to the usage conditions.And the castable can not only be directly poured into the lining of the kilns,but also be made into precast block in the way of pouring or vibrating.
Application
Building materials industry,iron and steel industry and energy industry
FS refractory materials institute co-production of electric furnace, converter spray feeding, The remarkable characteristics of goods has an excellent performance, the formation of spray coating structure is compact, high thermal strength, good anti - burst, strong corrosion resistance, good durability.
