Refractory Castables

Refractory is a class of materials which are produced from non-metallic minerals. They are the primary materials used in the internal lining of industrial furnaces, boilers and possess capability to withstand heat and pressure, and are used in steel, aluminum, glass, cement, petrochemicals, non-ferrous metals, thermal power plants and process units. These are produced in Special Shapes and are Custom made to suit the requirements of the various industries.

Refractories are classified on the basis of their chemical composition, end use, and manufacturing method. They can be classified as acidic, basic, and neutral refractories. A small range of high melting point materials like magnesia, bauxite, fireclay, and silica are used to produce refractories.
