On the Microstructure of a Freeze Lining of an Industrial Nonferrous Slag
Labscale freeze layers of an industrial nonferrous slag with Al2O3-CaO-FeO x -MgO-SiO2-ZnO as main components are studied to explore the microstructure and the composition of an industrial freeze lining. The freeze layers were formed by submerging a watercooled probe into a liquid slag bath. The influence of submergence time, of heat input …
Characteristics and environmental aspects of slag: A review
Slag examined in this study is defined as the predominantly silicate and oxide by-product derived from smelting metallic ore. The two main types of slag included in this discussion are from the primary production of ferrous ores, from iron and steel manufacturing, and from non-ferrous ores, from the recovery of base metals and some precious metals.
Non-Ferrous Metal
Non-ferrous metals include any metal that do not contain iron in appreciable amounts. Fig. 1 classifies the electrochemical studies reported on PM non-ferrous alloys by means of the main alloying element: Ti, Mg, Ni, Co, Al, Zr and Cu based alloys. Additionally, each group is divided by the type of electrochemical corrosion mechanism that was studied in the reported study: …
