耐火材料侵蚀过程对铁水脱磷处理工艺的影响分析

Analysis on Influence of Corrosion Process of Refractory Materials on Dephosphorization Treatment Technology for Hot Metal

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。

By the corrosion experiments on corundum refractouy or magnesia refractory containing zirconia-mullite with blast furnace slags, dephosphorizing agents or converter slop, it isproved that dephosphorizing agents with high Fe_2 O3 content bring strong corrosion to magnesia refractory but weak corrosion to aluminiun refractory. According to the service life of lining and processfactors, it is beneficial for aluminium -- refractory lining to be applied in dephosphorization processfor hot metal pretreatment.
