摘　　要：对采用镁砂晶粒平均粒径在４００～６００ｕｒｎ，石墨纯度达到Ｃ≥９８％，石墨的细度在０．１４７～０．１７８ｍｍ，金属加入物以铝粉与硅粉复合形式加入，生产出的ＭｇＯ－Ｃ供气元件性能较好。同时研究了碳化硼和固体结合剂对该材质的抗氧化性和高温强度等的影响。The quality of MgO-C permeable component for combined blowing converter wital N2/CO2 gas has been studied.The results indicate that the properties of the product with 400-600μm magnesia grain size,C≥98 % graphite purity,0.147￣ 0.1 78mm graphite fineness and combined aluminium-silicon fines are better. The effect of boron carbide andsolid bonding agent on oxidstion resistance and high temperature strength of the material has been investigated.
