Abstract :
Wear of various basic refractory materials to substitute to currently used magnesiachrome
bricks has been studied, measuring matte and slag penetration and dissolution, through
different cup and rotary slag tests. High magnesia with and without impregnation, magnesiagraphite,
magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivinemagnesia-
graphite bricks, as well as magnesia-graphite and olivine magnesia castables, have
been tested.It has been shown that carbon impregnation and graphite introduction into basic
refractories are feasible ways to enhance their corrosion-dissolution and penetration resistance
against fayalite as well as calcium-ferrite slags. Olivine-based refractories (castables or bricks)
may be considered as viable candidates to use in copper-making furnaces. At this point, evaluation
of the thermo-mechanical properties of this new class of materials is still missing.
