Refractory Interactions with Calcium Ferrite Slags
A joint research program is being carried out at the UNIVERSITY of MISSOURI-ROLLA (USA) and the G.K. WILLIAMS COOPERATIVE RESEARCH CENTRE FOR EXTRACTIVE METALLURGY (Australia) to investigate the effectiveness of chrome-free potential replacement refractories in copper furnace environments. The choice of refractories has been focused on commercially available materials in the magnesia-alumina system, which is similar to the magnesia-chrome system and has been the source of replacements for magnesia-chrome bricks in other industries. This work describes the results of exposing potential replacement refractories to the newer (and more aggressive) calcium ferrite slags. The primary analytical tools used included SEM/EDX and cathodoluminescence (CL) microscopy, which has proven a useful adjunct in refractory analysis.
