Refractories are used in heating units in process & core sector industries in different type of furnaces, kilns, driers,  gasifiers and reformers.
Operating conditions are often severe, with temperatures as high as 1400 - 1800 °C.
Usage can be categorized as regular, conventional refractories (fireclay, bricks, low alumina bricks,  dolomite bricks, etc.) and specialized refractories (high alumina).
