WFA fraction for Refractory

—Description
The WFA is the main raw material for the production of unshaped and shaped refractory materials.
Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products;
For the shaped refractory materials, it is mainly used in the high-quality raw materials of corundum brick, corundum mullite, refining steel porous plug brick, integral spray gun, steelmaking and continuous casting industry.
It also can be used as materials for polishing, precision casting, spraying and coating, special ceramics
