通过对溅渣转炉残砖的成分和矿相分析，讨论了高ＦｅＯ炉渣溅渣形成的溅渣层化学成分变化和岩相结构特点；分析提出溅渣层的形成机理和对炉衬的保护作用。实验研究证明，溅渣结合层的化学成分与终渣有明显的差别：ＭｇＯ含量高达５８．４ ％ ，而ＣａＯ和ＳｉＯ２ 含量大幅度降低。由于ＦｅＯ与ＭｇＯ高温烧结，在ＭｇＯ－Ｃ砖表面脱碳层内形成发达的烧结层，强化了炉衬与溅渣层的结合。由于溅渣层分熔和ＦｅＯ烧结作用，在炉衬—溅渣层结合界面处形成致密的、以大颗粒ＭｇＯ 为主相，ＭＦ和镁铁尖晶石为胶结相的高熔点结合层，有效保护了转炉炉衬。
Based on the analysis of the composition and the mineralogical phases of the residual brick in the slag-splashing converter, the chemical composition changes and the lithofacies structure characteristics of slag splashing formed by slag splashing by high FeO slag are discussed. The forming mechanism of splashing slag layer and the protective effect on the lining are analyzed. Experimental studies have shown that there is a clear difference between the chemical composition of the slag splashing layer and the final slag: MgO content as high as 58.4%, while CaO and SiO2 content significantly reduced. Due to the high temperature sintering of FeO and MgO, a developed sintered layer is formed in the decarburized layer on the surface of the MgO-C brick, strengthening the combination of the lining and the slag splashing layer. Due to the slag-splitting melting and the sintering of FeO, a compact high-melting-point bonding layer with large particles of MgO as the main phase and MF and the maficium-spinel as the binder phase is formed at the interface between the lining and the slag-splashing layer to effectively protect The converter lining.
