The authors of this study systematically investigate the influence of the main components of BaO-containing slag on its viscosity and thermal stability. The results indicate that the viscosity of slag significantly increases with the mass fraction of the crystalline phase. Increasing the slag basicity from 1.00 to 1.10 and the MgO content from 5.0% to 9.5% is an effective way to weaken the influence of crystallization on slag viscosity and improve the stability of BaO-containing slag. Al2O3 content over 11% is necessary to maintain a higher slag temperature, which enhances the ability of BaO-containing slag to resist the influence of crystallization on relative viscosity. When the heat of BaO slag is greatly reduced, increasing the slag basicity from 1.05 to 1.15 and MgO content to over 6.5% can help maintain the thermal stability of slag. The effect of Al2O3 content on the viscosity of slag under conditions of fixed heat is greater than that under constant temperature conditions. As the heat decreases, the Al2O3 content increase from 9% to 13% has a more significant effect on the viscosity and temperature of slag. A lower Al2O3 content in slag is advantageous for reducing the influence of heat fluctuation on slag viscosity. |
