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.
In the oxygenated pure iron, Ni, Cr, W, Mo, Al, Ti, B and mixed rare earth metals are added separately and in combination, and then qualitatively analyzed by means of the metallographic method, the lithofacies method, the X-ray powder method and the composition of the inclusions Such as CeO_2, FeO (including Ni), FeO (containing Mo), Cr_2O_3, Cr_3O_4, FeO · WO_3, α Α-Al 2 O 3 (including Ti, Ni, Cr), TiN, α-Ti 2 O 3 and boron-containing inclusions, etc. The above results confirm the composition and properties of the deoxidation products, Addition of alloying elements and oxygen affinity.
