An Introduction to the Types of Monolithic Refractories
May 10 2002 · Castable refractories are materials that contain precision-graded fine and coarse refractory grains. They are gelled with the help of a binder system in the material s green state. After the material is heated the binder either changes or volatilizes allowing the formation of a ceramic bond. Refractories must be able to withstand physical wear high temperatures (above 538°C 1000°F ) and corrosion by chemical agents. There are two general classifications of refractories clay and nonclay. The six-digit source classification code (SCC) for refractory manufacturing is .
