The weaknesses of submerged nozzles being used now were analyzed and ZrO2-CaO-BN composite was proposed to develop to overcome them.The feasibility to prepare Z
The developed self-flowing Al2O3-SiC-C castable for troughs of blast furnace(BF) can self-flow under its own gravity,leveling,degassing,compacting and setting w
The paper describes the reaction between car-bon-containing refractories,magnesia-chrome re-fractories and matte,converter slag.The results show that carbon-con
Using Al2O3-MgO castable in large ladle can avoid containation of molten steel from carbon-containing refractories and increas ladle servic life remarkably,The
