    More details Close

    The aluminum deoxidation equilibrium in molten Fe-10 to 40 mass%Cr-8 mass%Ni and Fe-18 mass%Cr-8 to 30 mass%Ni alloys was experimentally determined at 1 873 K and 1 773 K to obtain the thermodynamic parameters at both temperatures, corresponding to the refining and casting processes, respectively. Thermodynamic analysis on Al deoxidation was carried out based on the sub-regular solution model using a Redlich–Kister type polynomial. Fe–Al, Ni–Al, Cr–Al and Fe–Cr–Ni interaction parameters were obtained from experimental results and a thermodynamic assessment. Using these parameters, the Al deoxidation equilibrium over the complete composition range of the Fe–Ni alloy and in more than 50 mass%Fe of the Fe–Cr and Fe–Cr–Ni alloys can be calculated for the temperature ranges of both of the refining and casting processes.

    Slag as by-product of Cu making has been produced in large amounts in Chile, and around 5 million tons of slag are estimated to be disposed every year and 40 to 45 million tons have been accumulated. Typical Chilean Cu slag contains about 0.3 mass% Mo which is the grade of primary mine production of molybdenite and it also contains about 40 mass% of Fe and 1 mass% Cu. Recovery of Mo from Chilean copper slag is quite attractive to secure a stable Mo supply. The feasibility of the recovery of Mo from Cu slag as Fe-Mo alloys by carbon reduction is investigated in the present work. Mo in Cu slag is found to be fully recovered as Fe rich alloy. The recovered Fe rich alloy contains about 0.65mass% Mo and 2.4 mass% Cu. In addition, to use the recovered Fe-Mo alloy in the special steel industry, which is the most important market for molybdenum, Cu in the produced Fe-Mo alloy is successfully decreased from 2.4 mass% to 0.1 mass% by using FeS-Na2S flux. Thus, Mo recovery from Chilean Cu slag can be promising.

    Iron nugget making process by rapid heating reduction of powdery iron ore and pulverized coal mixture is regarded as one of the novel iron-making processes. Iron carburization during smelting reduction is especially important reaction step from the viewpoint of saving energy in this process. If the rate and efficiency of carburization reaction are increased, energy consumption of the process will be reduced to large extent. The purpose of this study is to clarify the carburization degree of iron nugget during smelting reduction of the mixture.<br>The sample was prepared from graphite, electrolytic iron powder and synthetic slag containing iron oxide to simulate iron carburization phenomena during smelting reduction of the mixture in the present work. The sample was quenched immediately after the mixture changed into nugget shape in a rapid heating process. Laser microscope combined with infrared image furnace was used for sample heating and observation of carburization phenomena, and carbon content in the nugget was chemically analyzed after quenching.<br>From above-mentioned investigations, it was revealed that the occurrence of carburization during smelting reduction in the sample mixture is advantageous to obtain higher carbon contain iron nugget.

    Metallic impurities in Si will decrease solar cell efficiency to a large extent. To discuss the possibility and efficiency of impurity elimination process, evaluation of thermodynamic properties of impurities in molten silicon are crucial. In the present work, thermodynamic properties of Fe in molten Si were investigated by Knudsen effusion method. The activity coefficients of Fe in molten Si for infinitely dilute solution relative to pure liquid, and self-interaction parameters at 1723-1823 K were determined.

    Acetylacetone was reacted with samples containing rare metals to form organic complexes of gases and recover the liquefied organic solvent. The spent LIB was composed of a mixture of metal oxides such as Co, Li, and Mn. This process does not require the use of different organic solvents for each of the mixtures of various oxides, but uses a single gasification organic solvent to produce an organometallic mixture containing these metals, allowing the simultaneous recovery of all the metals contained in the LIB. This method is an element separation method based on a completely new principle, and allows horizontal recycling and upcycling instead of downcycling.

    This study revealed the linkages between national resource consumption (Fe, Cu, Ni) and global impacts by using a global link input-output model (GLIO) and knowledge to increase the resource efficiency in metal recycling based on metallurgical thermodynamic approach. This study also revealed the fundamental importance of metal recovery from waste to avoid dissipations of resources. Possible options include the development of a sorting process for metal scrap aimed at alloy-to-alloy recycling. We also discussed measures for ameliorating or relaxing the differences between the grades of secondary materials and grade of raw material in metallurgical industry; measures such as a) upgrading the quality of pre-consumer materials by removing impurities, b) adjusting the quality of secondary materials by mixing and diluting, and c) relaxing the limits on impurities by refineries can be considered to close the loop for metal cycle.

    In this study, the dust generated during normal EAF steelmaking process was returned to the EAF by injection, and the regenerated dust was collected by using a bag filter. The amount and chemical composition of regenerated dust was continuously monitored by the particle sensor which was equiped in the dust collection system of practical EAF factory. The dust injection technology was determined to be very effective in reducing the dust treatment burden by decreasing the quantity and enhancing the quality of the regenerated dust. The regenerated dust was provided to the CaO addition process which was developed by the authors. It was confirmed that the most of zinc in the treated dust was recovered from the regenerated dust. Due to such a very good result, our partner EAF company applied the dust injection technology to their routine steelmaking operation and the total amount of dust generation was successfully reduced significantly.

    Experiments to immobilize chromium using the clay minerals such as smectite was conducted. Saponite didn't adsorb chromium ions. However, when using montmorillonite, under the condition pH is 2, chromium was decreased from 1ppm to below the environmental standard value of 0.05ppm. Further, when heated in an air atmosphere 1573K a montmorillonite containing Cr, it was possible to fixate Cr. It was confirmed that it is possible to immobilize intercalated metal ions into clay minerals.

    The global demand for metal resources has been sharply increasing by economic growth, and the issue of sustainable resource management has also been increasingly recognized. In order to optimize the material cycles and increase resource efficiency, material flow analysis (MFA) is a powerful tool to understand the resource consumption and material cycle in the national economy. However, MFA cannot provide technological information on the recoverability and/or removability of elements from secondary resources. This study proposed a combined application of MFA with thermodynamic analysis for sustainable resource use, and conducted detailed MFAs of metals, such as nickel, chromium and molybdenum, that were concerned with thermodynamic properties of elements

    Ti oxides have a lot of different crystal structures, and their structures varies depend on Ti concentration in the Fe-Ti-O system. Furthermore, they form compounds and the solid solutions with the Fe oxide. Therefore, understanding of the precipitation behavior Ti oxides that have a various crystal structure (various lattice distance) can be very important to develop the oxide metallurgy technology. Thus, as first step, and thermodynamic evaluation of the deoxidation equilibrium of various Ti oxides have been carried out. (1) The phase identification of Ti oxide of about 1μm generated in melt Fe-Ti-O alloy was carried out by using EBSD. Based on the results, the range of the oxygen concentration of molten Fe-Ti-O system in equilibrated with various Ti oxides melt Fe-Ti-O alloy was accurately determined. (2) For molten Fe-Ti-O system, the nucleation starting temperature was measured by using DTA, measurement of the nucleation generation temperature of the Ti oxide from melt Fe-Ti-O alloy was carried out, and it has been found that the nucleation gstarting temperature vary based on Ti concentration in molten Fe-Ti-O system. Moreover, to establish the correlation between the 2-dimensional precipitation behavior and actual 3-dimensional behavior, CaCO_3 precipitation behavior from the solutions was observed by using the microscope. The correlation of precipitation behavior in two dimensions and three dimensions was evaluated based on the Fractal model. Along with carrying those experiments, it was found that the small angle analysis of precipitated particles in the molten steel by synchrotron radiation is rather difficult. Therefore, the nucleation behavior of CaCO_3 from the solution was analyzed by using conventional X-ray with small angle diffraction analysis, and was confirmed that the distribution evaluation was possible for the particles with up to the diameter of about 10μm.

    後方電子散乱法(EBSD)は主に多結晶体結晶粒の方位測定・解析に用いられている。本研究ではEBSDが持っ高分解能で結晶構造を確定できるもう一つの特性を生かして微少領域の物質同定を行う表面分析手法のための基盤技術の確立を目的とした。従来の表面分析法のほとんどが測定点の相対的な元素比を測定するもので、複雑な化学式を持つ物質の同定は困難である。本研究ではEBSDが持つ測定点での菊池パターンに基づき構造情報が得られる特性を生かし、EBSDを方位測定でなく、微少領域における物質構造同定に用いる技術の開発をおこなった。 その有効性を実証するためEBSDを用いて、これまで困難であった鋼中に存在する初期生成微少介在物(0.1μm程度)の準安定相も含む物質同定をおこない、溶融Fe-Ti合金に存在する100nm程度のまでにいたる微少介在物の評価を行い。TiNや」各種Ti酸化物の同定が可能なことを実証した。また溶融Fe-Ti-O合金のTi-O脱酸平衡の正確な熱力学パラメーターを求めるには溶融合金を保持しているルツボと溶融合金界面に生成してる平衡Ti酸化物相を決定する必要があるがその厚さは数μであり、従来のX線解析などでは困難であった。しかし、本研究に於いてEBSDを適用することにより、その正確なTi酸化物相の同定が可能となり、その測定に基づき書くTi濃度に対応する信頼性の高い溶融Fe-Ti-O合金のTi-O脱酸平衡の各種熱力学的パラメーターを提案した。 高品位鋼の製造には介在物の制御技術が重要である。介在物の生成条件や特性を正確に把握するためには、生成機構を詳細に解明する必要がある。しかし介在物制御に重要な初期生成介在物の情報、例えば準安定相の存在、0.1μm程度の微少介在物内の組成分布や構造などはこれまで明確にされてこなかった。しかし本研究で確立したEBSD法を用いることにより微少介在物組成を評価する事が可能となることを実証した。

    地球表面の約70%を占める海には、地球上で最もCO_2固定能力が高い、海洋植物プランクトンが生在しており、炭酸ガスの削減・固定化を考える上では、キーとなる生物である。しかしながら、世界の海域の大部分では、海洋植物プランクトンが増殖する際に必要な栄養元素が極端に不足している。海洋植物プランクトンを増殖させ、CO_2の削減・固定をはかるためには、りん、珪素、鉄などの栄養元素がバランスよく存在する必要がある。一方、年間約100万トンが埋め立てに使用されている鉄鋼プロセスの副成品である鉄鋼スラグは、りん酸、珪酸、酸化鉄を豊富に含むイオン性結晶であり、植物プランクトンの増殖に必要な栄養元素の供給源として用いることができると考えられる。しかし、鉄鋼スラグには、クロムなどの重金属やフッ素が含まれている場合があり、これら有害な元素の溶出防止、安定化方法の確立が早急に望まれる。 プランクトンの成長・増殖を促進させるために有用成分を海水中へ加える際には、海水への有害成分の溶出各元素の添加技術が重要課題となる。H14-16年度の科学研究費では、スラグ中結晶相の水溶液中での安定性が、栄養成分溶出挙動に大きく影響することがわかり、海水への成分溶出挙動メカニズムを解明しつつある。本成果を応用して、H17-18年度に製鋼スラグから有害元素が溶出しいような安定化技術の開発を行う。 H18年度は、複合結晶相からの海水中への成分溶出試験、鉄鋼スラグからの成分溶出試験を行い有害元素の溶出挙動を調査し、有害元素の化合物相が完全に安定・無害化されていることを確認した。

    植物プランクトンの増殖にはさまざまな塩類や元素が必要であり、それらの成分がバランスよく海水に溶存しているときに、植物プランクトンの増殖効率は高くなる。大部分の種類の海洋植物プランクトンは、単細胞とみなせ、夏場などの好気象条件下では、一日で1,2回細胞分裂を起こし、極めて早く増殖するのが特徴である。そのときプランクトンが体内に取り込む栄養素は、元素比でFe:P:Si:N:C:O=0.001:1:15:16:106:212(Redfield's ratio)である。すなわち、鉄を海水中に1モル供給し、これを全てプランクトン増殖に利用できたとすると、その体内にCO_2を106000モル吸収できることになる。しかし、実際の海洋においては、海域により、増殖のために必要な栄養元素が極端に不足しており、それらの貧栄養素の供給が律速となり、増殖するのが困難となっている。 プランクトンの成長・増殖を促進させるために有用成分を海水中へ加える際には、海水への各元素の添加技術が重要課題となる。本研究では、鉄鋼スラグからの栄養成分溶出挙動およびメカニズムを解明し、海水中の栄養元素が適正な濃度比で存在させるような技術開発をおこなう。また、製鋼スラグから有害元素が溶出しないような安定化技術の開発を行う。 複合結晶相からの海水中への成分溶出試験 平成16年度は、複合結晶相を人工的に合成し、人工海水中への溶出試験を行った。海水中有害元素濃度およびpHの経時変化を測定し、海水中への成分溶出速度および飽和溶解度を測定した。また、複数の結晶相がスラグ中に存在した条件での、有害元素の溶解挙動を明らかにした。
