A rotating basket cathode improved the TiO₂-reduction efficiency by 6.5-fold and accelerated the electrolysis of molten CaCl₂-CaO at 1173 K in an Ar atmosphere. Promoting dissolution of the CaO byproduct and mass transfer near the cathode was effective for TiO₂ reduction and α-Ti deoxidation. The reduction efficiency can be predicted by optimizing the rotational speed and pulse rotation.

The mini blast furnace process is an efficient route to produce pig iron based on the burden with granulated charcoal. New, improved technologies have recently been introduced in the mini blast furnace process, such as pulverized charcoal and gas injections, new burden materials, and peripheral devices that improve the overall process efficiency. In this paper, we revise the new injection possibilities and discuss new aspects for further developments. The analysis is carried out with a comprehensive multiphase multicomponent mathematical model using mass, momentum, and energy conservation principles coupled with the rate equations for chemical reactions, multiphase momentum, and heat exchanges. We analyze new technological possibilities for the enhancement of this process as follows: (i) a base case of pulverized charcoal injection with industrial data comparison; (ii) a set of scenarios with raceway injections, combining pulverized charcoal with hydrogen-rich fuel gas, replacing granular charcoal in the burden; (iii) a set of scenarios with hydrogen-rich gas injection at the shaft level, replacing reducing gas in the granular zone of the reactor; and the possible combination of both methodologies. The simulated scenarios showed that a considerable decrease in granular charcoal consumption in the burden materials could be replaced by combining a pulverized charcoal injection of 150 kg/tHM and increasing rich gas injections and oxygen enrichment values, decreasing the specific blast injection and granular charcoal. The productivity of the mini blast furnace process was increased for all scenarios compared with the reference case. We review the aspects of these operational conditions and present an outlook for improvements on the process efficiency.

A liquid metal electrochemically deposited in CaCl2 or its chloride melts serves as an effective reductant for active metal oxides. Although a very low oxygen concentration can be achieved at a considerably high electrolysis efficiency, the existence of small amount of water impurity in molten chlorides, which is very difficult to detect, causes low electrolysis efficiency. In this study, to clarify the morphological and thermal characteristics of a cathodic electrode in a slightly hygroscopic LiCl–KCl–CaCl2 melt, we simultaneously performed electrochemical measurements and thermal measurements using an ultrafine thermocouple inserted inside a Mo electrode (i.d. 1.57 mm). Concomitantly, changes in the electrode interface were recorded at 500-μs intervals using a synchronized high-speed digital camera. Despite the small amount of water included in the system, the measured heat absorption was much smaller than thermodynamically predicted, which suggested that the generated hydrogen decreased the purity of the liquid alloy electrodeposited on the cathode surface possibly through hydride formation. By using the synchronized thermal measurement, it was possible to trace the change in the electrodeposition pattern of impurity water quickly and sensitively, which was difficult to determine in only the electrochemical potential-current response.

From the viewpoints of the limited deposit of natural resources and the protection of global environment, utilization of iron scrap is strongly requested. For estimating the effectiveness of the moving bed type scrap melting furnace, a two-dimensional mathematical model has been proposed, which considered transport phenomena of heat, mass and momentum together with melting and chemical reactions in the furnace for iron scrap melting. Numerical simulation was conducted to investigate in-furnace phenomena and effects of operating conditions on the process stability. According to the numerical results, the blast preheating was very effective for reducing coke consumption, because the coke rate can be reduced to 200 kg/t when it preheated to 673 K without oxygen enrichment. As the results, the process characteristics such as distributions of gas concentration, temperature and velocity have been obtained; they are useful to evaluate the performance of the iron scrap melting furnace and to improve the operations leading to less energy consumption and more iron scrap melting.

The multiple injection of carbonaceous materials and oxygen enrichment in the blast furnace has received especial attention in the recent years due to its possibility of considerably decrease in coke rate and increase of the productivity. This paper introduces a modeling of the co-injection of pulverized coal and natural gas into the blast furnace through the tuyere. This model treats the blast furnace as a multi-phase reactor and five phases are treated simultaneously: gas, lump solids (iron ore, sinter, pellets and coke), pig iron, molten slag and pulverized coal. Conservation equations for mass, momentum, energy and chemical species are solved simultaneously based on the finite volume method. Firstly pulverized coal is simulated and afterwards only natural gas is investigated and compared with the all coke operation. Finally, the combined practice is suggested in order to improve the actual blast furnace operation. The simulation results have contributed to better understanding the blast furnace phenomena with multiple injectants, and supported new improvements in the furnace operation. The results obtained in this investigation have shown the possibility of considerable advances in the actual blast furnace operation such as increase in productivity, lower silicon content in hot metal and decrease of the coke and slag rates. In addition, the total amount of the greenhouses in the off gas is decreased, which contributes to make the blast furnace process cleaner.

The blast furnace process is a multi-phase chemical reactor whose main purpose is to reduce iron oxides producing hot metal. In the actual blast furnace operation several phases simultaneously interact with one another exchanging momentum, mass and energy. In this paper a three-dimensional multiphase mathematical model of the blast furnace is presented. This model treats the blast furnace process as a multiphase reactor in which all phases behave like fluids. Five phases are treated by this model, namely, gas, lump solids (iron ore, sinter, pellets and coke), pig iron, molten slag and pulverized coal. Conservation equations for mass, momentum, energy and chemical species for all phases are solved based on the finite volume method. In the discretized momentum equations, the covariant velocity projections are used, which is expected to give the best coupling between the velocity and pressure fields and improve the convergence of the calculations. This is a new feature of the present model regarding to the numerical procedures applied to the blast furnace modeling, which emphasizes its originality. In addition, gas and solid phases are treated as continuous phases possessing a pressure field and the SIMPLE algorithm is applied to extract the pressure field and ensure mass conservation. Hot metal, slag and pulverized coal are treated as discontinuous phases consisting of unconnected droplets. For such phases, momentum conservation is used to calculate the fields of velocity while the continuity equations are used to calculate the phase volume fractions. This model was applied to predict the three-dimensional blast furnace operation and predicted temperature distributions and operational parameters like productivity, coke rate and slag rate presented close agreement with the actual measured ones in the blast furnace process.

This paper introduces a modeling of the co-injection of pulverized coal, pre-reduced iron ore and flux into the blast furnace through the tuyere. This model treats the blast furnace as a multi-phase reactor. The pulverized coal and pre-reduced fine ore/flux have different chemical and thermophysical properties, thus these materials are treated as separate phases. Therefore this model considers six phases: gas, lump solids (iron ore, sinter, pellets and coke), pig iron, molten slag, pulverized coal and pulverized iron ore/flux. Conservation equations for mass, momentum, energy and chemical species are solved simultaneously based on the finite volume approach. Two operational practices are investigated. One is the injection of pre-reduced fine iron ore and pulverized coal, and the other is the co-injection of pre-reduced fine ore, flux and pulverized coal. The simulation results have contributed to better understanding the blast furnace phenomena with multiple injectants, and supported new improvements in the blast furnace operation. With this model, the injection of pulverized iron ore and flux together with pulverized coal has been proved to be possible at high rates keeping stable blast furnace operation. Moreover, the silicon content can be lowered and the furnace productivity can be largely increased.

Surface temperatures of metals subjected to transferred arc plasma impingement in 100 % argon and Ar-H2 (90 : 10 and 70 : 30 by volume) mixed gas arc plasmas are predicted based on a combined mathematical model of the arc plasma and the metal bead. The numerical simulation involves solution to conservation equations of mass, momentum, energy, and current continuity of the arc plasma and the target metals of Nb and Ta. An increase in hydrogen content of the introduced gas resulted to higher surface temperatures as well as an increase in the size of the molten pool. Predicted threshold arc current that causes an onset of melting is in good agreement with experiment.

In this study, we investigated the growth process of M7C3 carbide by a Confocal Laser Scanning Microscope. Fe-C-Cr alloy was prepared using an arc furnace. The composition was determined to be Fe:C:Cr=55:5:40(wt%). From the results of XRD and EPMA, the Fe-C-Cr alloy contained M₇C₃ carbide in the internal structure. In condition of two cooling rates 60°C/min and 30°C/min observed with a Confocal Laser Scanning Microscope. Corners of the Hexagonal structure grew in the preferred orientation direction of M₇C₃ carbide at 60°C/min. After the growth of preferred orientation direction, the M₇C₃ carbide formed to connect between the corners. At a cooling rate of 30°C/min, M₇C₃ carbides grew in oblique direction to the observation area. At the beginning, the structures were hidden in the fluid. But the structures started to grow, the shape of the hexagon became eventually. After the melting experiment, the samples were observed by Optical Microscope and Scanning Electron Microscope. As a result, since hexagonal structure arose a difference in height between the outside and the inside. M7C3 carbides grew from the outside in the solidification process.

Mass and heat transfer to a liquid film formed on the circumferential surface of a rotating cylinder which is immersed into a liquid bath was studied. Liquid flow rate passing over the rotating cylinder was measured under various immersing depths and rotating speeds. The average velocity of the liquid film was much slower than the circumferential speed of the rotating cylinder. The gas absorption rate to the liquid film was measured. The absorption rate under cylinder rotation case was much higher than that in the fixed case, and it increased with the increase in the rotation speed. The mass transfer coefficient increased up to three times in the tested conditions. These results suggested that the mass transfer rate could be controlled by the cylinder rotation.

Energy cascade utilization from higher temperature to lower temperature processes is necessary to establish a sustainable society. Latent heat storage (LHS), the heat is stored by using the latent heat of phase change material (PCM), is one of the key methods. However, a solidification layer of PCM on the heat exchange wall blocks the heat transfer, in consequence, it takes a long time to release the stored heat. Authors proposed a new concept for rapid heat exchange for LHS, "Scraping Solidified Layer of PCM on the heat transfer wall", which, heat transfer tube is rotated, and solidified PCM on the tube is continuously removed by fixed blade. In this study, laboratory scale setup (PCM weight: 1 kg) was developed, and the effects of rotation rate on the heat transfer rate and the heat utilization ratio were examined experimentally. The results showed that the heat release rate during rotation is accelerated by more than 100 times compared with the rate without rotation.

We conducted new chemical engineering experiments by using analgebraic calculator. Data collecting equipment and variety sensors can be connected to thecalculator. The recording method of experimental data could be changed from manual toautomatic by the calculator. As a result, the complicated experimental procedure becamesimple and the experimental data range was expanded. In addition, the students were able tomake new analytical or measurement instruments by themselves, combining both the algebraiccalculator and the sensors. The introduction of the algebraic calculator could expand thecontent of chemical engineering experiments.

The utilization of Green Hydrogen in the ironmaking and steelmaking process is to contribute to the reduction of CO2 emission in Japan. In this study, the main purposes are to clarify the possibilities for two cases, the first case is the use of hydrogen in the present blast furnace processes, and the second case is the future hydrogen furnace without coke. The mathematical model of the blast furnace was developed for clarifying the effect of hydrogen. Using this simulation model, it was found that the limit of hydrogen injection into blast furnace was about 40%. The hydrogen gas system can inject a larger amount of gas which is important factor for increasing the productivity. The metallic iron obtained by hydrogen reduction is close to a pure iron with low inclusions, which is predicted by thermodynamic analysis. The experiment was performed to clarify the result of thermodynamics. It was confirmed that high purity iron was obtained.

平成12年度の実績は以下の通り。昨年までに現行製鉄業における各種プロセスの最新操業データを入手したのち、プロセスの物質収支の確認に着手し、ほぼその流れをつかむことに成功した。さらに、修正エンタルピー法に基づき製鉄所内全体のエンタルピーフローを明らかにした。今年度は整理された操業データに基づき、現行および省エネ前のデータに基づきエクセルギーフローを計算する事が可能となり、一部着手することができた。これらの計算は関連するすべての物質の温度依存性を考慮した熱力学データを組み込んだ計算機プログラムを開発して、大規模計算を行うことにより可能とした。さらに昨年度は得られたデータに基づき、現行の鉄鋼業がかかえる問題点、すなわちエクセルギーが大きく消費されている場所と量に注目して、新システムを考察し、予備的実験を行った。すなわち、高炉スラグ(酸化物多元系融体、1600℃を有するものの現在すべて廃棄されている。)や転炉排ガス(CO-CO2系燃焼排ガス、1600℃の超高温で排出されるがその回収方法は不十分。)などエクセルギーが大きく消費されている部分に着目してそれらを減少させるプロセスを基礎的に検討した。さらにこれらの結果を受けて、本年度はセメントおよび鉄鋼業の共生の可能性を検討した。その結果、スラグ廃熱使うならば、セメント産業で行われている石灰石の熱分解を行える十分な能力を有しており、その量は1000万トン程度にのぼることが明らかとなった。

Brazilian cooperative researchers studied physico-chemical properties of dusts generated in both BF ironmaking and EAF processes. For the former which does not contain zinc, cold bonded pellets having carbonaceous materials, produced from the dust are reported to have enough strength and reducibility as well as no swelling and broken out therefore being proved as sound raw materials for both gas reduction and smelting reduction processes. For the EAF dust which contains considerable quantity of the complex spinel of (Zn, Fe, Mn)Fe_2O_4, strength and reducibility have been studied. As the results, abnormal swelling was found to occurs when it was heated to 1060C, 95%Zn was removed when it was heated over 1200C, and about 70% Zn was vaporized as ZnO and concentrated in dust when it was processed in smelting reduction. The crude zinc obtained can be used as raw materials for zinc smelting. Cooperative researchers in Japanese side are developing a coke filter process for the separation of zinc from iron. In this method, zinc contained in the EAF dust as complex spinel structure can be evaporated in coke moving bed heated over 1000 C and recovered as liquid zinc in a condenser. On the other hand iron is reduced in the coke bed in solid state and discharged together with coke and recovered in conventional or smelting reduction ironmaking processes. Behavior of over micron particles has been studied in our lab. resulting in high efficiency separation by using a coke packed bed. However, EAF dust contains high quantity of sub micron particles. In this study, we investigated filtration of such sub micron particles by using a cold model of the coke filter process. However, complete result has not yet obtained. In addition, a fundamental study has been made on the recovery of thermal energy from molten slag together with uniformly sized fine slag particles applying chemical reaction. Atomization of wax was studied by using a quasi-hot model of a rotating cup-atomizer and atomization of high temperature molten slag has also tested. Fine particles of considerably uniform size (about 0.7mm) were obtained for wax atomization and fine particles were also obtained for slag pulverization, which provided a positive basis for developing a practical process.

本研究は、高付加価値材料を製造する際の出発素材として注目されている粒度・形態が均一に制御された金属あるいはセラミックスの超微粒子を、溶融金属に反応性プラズマを照射して発生させる製造法において、超微粒子生成過程における超微粒子の粒度・形態を支配する因子を明らかにするとともに、微粒子の発生速度・成長速度を反応速度論的に把握することを目的として行われた。ここでは窒化チタンを対象に、発生容器内を窒素で置換した後に、試料台上で溶解させた数十gのボタン状金属チタンに、種々のプラズマ条件(電圧,電流,ガス供給量等)に設定した反応性プラズマを照射することによって超微粒子を発生させた。しかし、微粒子発生速度を反応速度論的に解析する際に必要となる試料温度,周囲の伝熱および物質移動環境の各プラズマ条件による変化を実験時に把握することが困難であった。そこで、反応性(アーク)プラズマ照射時の試料容器内の状況を数値解析により把握するための数学モデルの作成を行った。本数学モデルは、試料容器内の流動および熱と物質の移動状態を表現するため、連続の式,運動量保存式,電熱方程式,物質保存式および乱流エネルギーとその消散率の保存式から構成され、これらの方程式を連成して解いている。現在のところ実際のプラズマ条件での解析には至っていないが、プラズマト-チ直下ではガス流速が大きく、伝熱速度および物質移動速度が大きくなっているのに対して、試料台の周辺,ト-チ側部およびガス流出口付近での流速が非常に遅くなっていること、また、ト-チ側部には循環流が形成されており、発生した超微粒子の補集時には注意を要することが示唆された。現在、実際のプラズマ条件下での数値解析について検討を継続しており、今後その結果を踏まえて実験結果の速度論的な整理,検討を行う予定である。
