Recent advances in silica-alumina refractory: A review

01.06.2014· Refractory materials can be divided into several classes based on: chemical composition (acid, basic and special), method of implementation (shaped and unshaped), method of manufacture (fused and sintered), and porosity content (porous and dense). These materials are supposed to be resistant to heat and are exposed to different degrees of mechanical stress and strain, corrosion from …

Lining (Refractory) - an overview | ScienceDirect Topics

01.01.2012· The slagline refractory includes two layers: an overlaying monolithic material and a backing refractory lining with a thickness of 30–50 cm. The bricks are made from magnesite and carbon (10–20% graphite), bonded by a carbonaceous resin. The role of carbon is to reduce the porosity of the bricks and lower the wetting between slag/refractory, hence lessen the chemical attach. Also, it
