为了分析中低合金钢中的稀土相,通过冶炼和物化合成了数种钢中可能生成的稀土和铝、铁、硫、氧化合物。并分别测定了这些化合物在一些化学试剂中的稳定性,寻找了各化合物的分离条件,确立了钢中稀土相系统的分离方法:首先用甲醇电解液电解分离固溶稀土,用碘-甲醇处理电解残渣溶解稀土硫化物,再用稀盐酸、柠檬酸溶解稀土硫氧化物,最后残渣中为稀土氧化物,把各相制成溶液,分别测定各相中的稀土含量,即为稀土元素在各相中的分配。本法实用价值较大,为稀上钢合金化机理研究提供了一种手段。
In order to analyze the rare earth phase in medium and low alloy steels, rare earths and aluminum, iron, sulfur and oxygen compounds possibly formed in several types of steels were synthesized by smelting and physicochemical methods. The stability of these compounds in some chemical reagents were determined. The separation conditions of each compound were determined. The separation method of rare earth system in steel was established. First, the solid solution rare earths were electrolyzed and separated with methanol and treated with iodine-methanol Electrolytic residue dissolved rare earth sulfide, and then dilute hydrochloric acid, citric acid dissolved rare earth sulfur oxides, the final residue for the rare earth oxide, the solution is made into each phase were measured in each phase of the rare earth content, that is rare earth elements in each Phase distribution. The practical value of this law is larger, which provides a means for the research on alloying mechanism of rare-levied steel.
