摘　　要：在铁水脱硫喷枪用耐火浇注料中加入不同量的红柱石颗粒,研究红柱石对脱硫喷枪用耐火材料各项指标的影响。实验结果表明,随着红柱石添加量的增加,喷枪用耐火材料的强度和体积密度降低,气孔率升高,线变化率增大,能有效提高耐火浇注料的热震稳定性。With adding different amount of andalusite particle into refractory used for desulfurization spray gun for hot metal, effect of andalusite on every item index of refractory used for desulfurization spray gun was studied. Experimental results showed that with the increase of andalusite addition amount the strength and bulk density of refractory used for desulfurization spray gun will decrease, the porosity and line rate change will increase, and the thermal shock resistance of castable refractory can be improved.
