在含氧纯铁中,分別并按组合方式加入Ni,Cr,W,Mo,Al,Ti,B和混合稀土金属,然后利用金相法、岩相法、X射线粉末法和夹杂物的组成定性分析等方法研究了这些脫氧产物的光学性质,化学性质和晶体结构. 试验结果肯定了脫氧产物的类型有:CeO_2,FeO(含Ni),FeO(含Mo),Cr_2O_3,Cr_3O_4,FeO·WO_3,α-Al_2O_3,α-Al_2O_3(含Ni),α-Al_2O_3(含Ti,Ni,Cr),TiN,α-Ti_2O_3及含硼夹杂物等. 上述结果肯定了脫氧产物的成份和性质,主要取决于所加合金元素与氧的亲和力.
Ni, Cr, W, Mo, Al, Ti, B and misch metal were added separately or in combination into pure iron containing 0.166% of oxygen. Optical and chemical properties as well as crystal structure of various types of nonmetallic inclusions present in the alloys were studied. The inclusions identified as in these alloys are CeO_2, FeO (with Ni), FeO (with Mo), Cr_2O_3, Cr_3O_4, FeO·WO_3, α-Al_2O_3, α-Al_2O_3 (with Ni), α-Al_2O_3 (with Ti, Ni, Cr), TiN, α-Ti_2O_3 and a certain kind of boride. The present results confirmed that the composition and properties of a deoxidation product are mainly determined by the affinity between the alloying element used and oxygen.
