| Abstract: | The MgO-CaO-C brick was prepared using the hydration-resistance treated magnesia-dolomite clinker as starting material.The inclusion amount and oxygen content in molten steel after using the developed MgO-CaO-C brick in ladle lining were analyzed and studied.It is found that constructing the MgO-CaO-C brick in nonslagline area in the sidewall of ladle can decrease the oxygen content and inclusion amount in molten steel and the inclusion size,change the particle size distribution of the inclusion and therefore improve the quality of the molten steel. |
