Slag corrosion of alumina-magnesia-carbon refractory bricks …
Resin pyrolysis, carbon oxidation (graphite and glassy-carbon), spinel generation (by certain specific mechanisms) and carbothermal reduction of MgO are the inherent reactions to the refractory in which gases are formed. The gases will form bubbles after the slag softening, i.e. at temperatures higher than 1350 °C.
