以高炉渣、脱磷剂及转炉渣侵蚀加人了锆莫来石的刚玉质与镁质耐火材料，发现高氧化铁含量的脱磷剂对镁质耐火材料侵蚀严重，对铝基耐火材料的侵蚀较弱，从炉衬寿命及工艺因素看：采用铝质耐火材料内衬对铁水预处理的脱磷过程有利。
With blast furnace slag, dephosphorization agent and converter slag erosion corundum and magnesia refractories added with zirconium mullite, it was found that dephosphorization agent with high iron oxide content corroded magnesia refractory seriously, and the corrosion resistance of aluminum-based refractories Erosion is weak, from the lining of the life and process factors to see: the use of aluminum refractory lined iron pretreatment dephosphorization process is beneficial.
