【摘要】 通过在镁铬砖中加入不同含锆添加剂,得出当ZrO2加入量为3%可降低镁铬砖的气孔率,并提高其抗炉渣的渗透性,剥落性,而脱硅锆和斜锆石的加入进一步提高了镁铬砖的抗侵蚀性.更多还原

【Abstract】 By adding ZrO₂ containing additives into magnesite-chrome brick of 20%Cr2O₃,the result here is that the porosity in MgO-Cr₂O₃ brick can be reduced when the additive content is 3%,so its slag resisting permeability is improved,and its drop-resisting capability is increased as well.The slag’s corrosion resisting capability is improved by adding silica-removed zircon and baddeleyite but the pores are made more when adding calcia zirconate,resulting in the weakness of slag’s corrosion resisting capability.更多还原
