Fireclay Refractory
Fireclay Refractory
the most common type of alumino-silicate refractory product. Fireclay refractories contain 28–45 percent Al2O3. They are made from refractory clays and kaolins cut by the addition of fireclay or, sometimes, nonplastic clay rocks and quartz. They are used in blast, reheating, and roasting furnaces; they are also used in pouring steel and in other operations.
