| 1 | OXIDE METALLURGY-ITS PURPOSES AND PRACTICAL APPROACHES显示文摘Useder certain conditions, nonmctallic inclusions such as oxides, sulfides, nitrides and carbides are no longer harmful to sted service properties. With the new concept of oxide metallurgy, these properties can be improved by generating fine oxide inclusions which serve as heterogeneous nuclei for sulfide and fine ferrite[1-4]. A novel continuous casting (CC) process is expected to be created with the utilization of oxide metallurgy. This is also useful for the forthcoming technologies of direct rolling and near-net-shape casting. The main idea of oxide metallurgy consists of an alternative oxidation technology. It is based on steels treated by complex metals such as Ti, Zr, Ti-Zr alloys and rare earth metals. The selected deoxidants should follow the required conditions which are concluded in this paper. | Z.T.Ma D.Janke | 1998 | Acta Metallurgica Sinica(English Letters)1998，11，2： | 6 |

| 3 | PROCESS CONTROL IN THE OXYGEN STEEL PRODUCTION显示文摘To achieve a high productivity and low costs in modern steelmaking, for example, oxygen top blow,bottom blow and combined processes, the following problems have been discussed in detail: (1) Sampling problems (data aquisition, precision, reliability); (2) Process problems (mostly of metallurgical and technological kind); (3) Method specific problems (choice of the analysis method). | H.Gutte T.Schulz G.Neuhof D.Janke | 2000 | Acta Metallurgica Sinica(English Letters)2000，13，6： | 1 |
| 4 | A STUDY ON THE BEHAVIOUR OF GALLIUM IN THE IRONMAKING PROCESS显示文摘Gallium is a valuabie rare metal which is mainly being used in the production of GaAs,The demand for gallium is increasing but production is limited since gallium is ex-tracted only as a by-product of bauxite processing.On the other hand cool,ironmaking coke and iron ore gangue contain traces of gallium.However little is kmown about the behaviour of gallium in ironmaking.The aim of the study is to clarify the distribution of gallium between hot metal,slag and top gas by means of laboratory experiments.It was found that Ga2O3 is not stable in blast furnace slags and that gallium is retained in hot metal.Vacuum distillation experiments with hot metal showed that gallium is not transferred to thw gas phase.Data on the input and output of gallium ot two industrial blast furnaces,as well as chemical analyese of the gallium content of several cokes are presented,too. | L.Savov S.Garonin O.Ivanov Y.S.Fusfin D.Janke | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，2： | 0 |
| 5 | ELECTROCHEMICAL MEASUREMENTS OF COMPONENT ACTIVITIES IN METALLURGICAL SLAGS显示文摘The up-to-date status of FeO, CaO, SiO2, P2 O5, Ti2 O3 and Cr2 O3 activity measure-ments in metallurgical slags using electrochemical sensors is outlined. A descriptionof theoretical concepts and practical sensors is presented including their determiningfeatures. | O.Volkova P.R.Scheller and D.Janke | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，6： | 0 |
