| Abstract: | The refractory castables for stirrer were improved using fused mullite,sintered zirconia-mullite as main starting materials,Al-80 cement,α-Al2O3 micropowder,ρ-Al2O3 micropowder and SiO2 fume as composite binders,through formulation design,properties testing,microstructure analysis,industrial test and actual application in order to dissolve the problems of the serious damage of refractory castables working linings for high intensity desulfurization stirrer and the quick reduction of stirring performance.The average service life of the improved castables is over 425 cycles on a 200 t hot metal ladle. |
