Surface Treatment of Magnesia-Calcia Firebricks with CO₂

Abstract:

For the hydration of magnesia-calcia refractory, this paper uses a new hydration-resistance technology. Namely using chemical methods, through surface and CO₂ occurring chemical reaction which generates CaCO₃ layer. The surface of magnesia-calcia firebricks are modified so that closed or stability, playing a role in hydration-resistance, and significantly improves the hydration-resistance. By SEM energy spectrum analysis and hydration resistance test, we obtained optimal technological parameters: reaction temperature is 700 °C for 4-5 hours, suitable water vapour temperature is 40°C, and the appropriate CO₂ flow is in the 4-4.5L•min^－1.
