摘　　要：以ＭｇＯ＞９５％的电熔镁砂和ＭｇＯ＞９３％的烧结镁砂为主原料，膨润土、ＣａＯ等为辅料，以复合磷酸盐和硅酸盐为粘结剂，再添加些外加物，如ＳｉＯ２、Ａｌ２Ｏ３微粉，配制的ＲＨ真空精炼炉浸渍管用热喷补料，各项性能指标和使用效果均达到国外同类产品的先进水平。The hot gunning refractory for the impregnated tube of RH vacuum refining furnace is made up of the fused magnesia (MgO>95% ) and sintered magnesia (MgO>93% ) as main materials, bentonite and CaO as subsidiary materials, compound phosphate and silicate as bonds and superfine powder of SiO2 and Al2O3 as additives. All its performance index and service effect have reached the advanced level of the similar products abroad.
