Effect of In-Situ Spinels on Al_2O_3-MgO-C Ladle Bricks Properties and Slag Corrosion Resistance

摘要

The aggressive operational environment of the steel ladles brings into discussion the need to better understand the main lining wear mechanisms in order to increase the ladles availability and reduce costs associated with refractory installation and maintenance. The wear mechanism of the Alumina-Magnesia-Graphite (AMC) bricks used at the metal zone of ladle corresponds to a combination of different chemical, thermal and mechanical stresses.
