Webrefractory, any material that has an unusually high melting point and that maintains its structural properties at very high temperatures. Composed principally of ceramics, refractories are employed in great quantities in the metallurgical, glassmaking, and ceramics industries, where they are formed into a variety of shapes to line the interiors of furnaces, … WebRefractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying. Mill scale is a nuisance when the steel is to be processed. Any coating applied over it is wasted, since it comes off with the scale as moisture laden air gets under it. All mill scale need to be removed to present a uniform and clean surface of the substrate steel for any application of any coating on the steel. dr schore prospect
