Chapter 3, Steel Plant Refractories

2010-9-29  For our purposes, refractories will be classified with reference to the raw materials used in their preparation and to the minerals predominating after processing for use. This classification is believed to offer the best possibility for a clear understanding of the origin and nature of steel plant refractories. 3.1.1 Magnesia or Magnesia–Lime Group

11.5 Refractory Manufacturing

2015-9-10  Refractories are materials that provide linings for high-temperature furnaces and otherprocessing units. Refractories must be able to withstand physical wear, high temperatures (above538°C [1000°F]), and corrosion by chemical agents. There are two general classifications ofrefractories, clay and nonclay. The six-digit source classification code (SCC) for refractorymanufacturing is 3-05-005. Clay refractories are produced from fireclay (hydrous silicates ofaluminum) and alumina (57 to 87.5 percent). Other clay minerals used in the production ofrefractories include kaolin, bentonite, ball clay, and common clay. Nonclay refractories
