Bricks fabricated for high temperature furnace lining: fly-ash+granite-powder+alite-cement+black-sand - Softcover

Inhaltsangabe

Industries associated with high temperature applications such as steel making and iron making industries make use of refractory bricks to carry out their entire manufacturing process. Different steps involved in manufacturing steel involves different types of refractory bricks based on various factors like working temperature, thermal stability, strength, wear resistance, chemical resistance. These bricks are to be replaced after certain duration of time for efficient functioning of the manufacturing units. The production of these refractory bricks involves so many complicated methods which are likewise expensive. As the need of such bricks is humongous for large scale industries, instead of manufacturing these bricks they import the bricks from other countries. Fly-ash, which covers major proportion of world’s industrial waste is known to have very high silica and alumina content. These compounds are known to be some of the important mineral compounds for the manufacturing of refractory bricks which has led to the ideology of using fly-ash for manufacturing of bricks incorporated with additive materials namely granite-powder, alite-cement and black-sand.
