    Negative effect from low coke rate operation at cohesive zone is obvious because it makes thinning of coke slit thickness. Correct knowledge about gas permeability of cohesive layer is becoming more and more important. In order to precisely understand cohesive behaviour, a softening and melting simulator under rapid heating and quenching conditions was applied for clarify a determinant factor of gas permeability behaviour. To focus on softening and melting behaviour, granulated slag particle bed layer without iron oxide was prepared as packed bed sample layer can show softening and melting. The packed bed slag samples in graphite crucible were rapidly heated up to 1200°C, and then gradually heated up to 1500°C with 10°C/min under inert gas atmosphere and 0.1 MPa load. Gas pressure drop and shrinkage degree of the sample layer were measured during the softening and melting test, and quenched sample was made at certain temperature when the maximum gas pressure drop was measured. The CT observation of the quenched sample provided 3D shape information of gas path shape in sample packed bed. Gas pressure drop was estimated with fanning’s equation with the gas path information. The estimation values were shown positive correlation with measured maximum pressure drop. The CT observation also gave triple line length among molten slag, graphite, and gas. Combination the triple line length and molten slag surface tension could use for evaluation of static force balance when maximum pressure drop obtained.

  • Effect of Gangue Distribution on Compressive Strength of Iron Ore Granules Reviewed International journal

    #Ginichiro Sato, @Tatsuya Kon, @Ko-ichiro Ohno

    ISIJ International   63 ( 10 )   1619 - 1625   2023.10   ISSN:09151559 eISSN:13475460

    <p>In recent years, the gangue component in iron ore deposits has increased owing to the increasing scarcity of high-grade iron ore. Such high levels of gangue causes a loss in strength of the granules used in the sintering process and a decrease in operating efficiency. In this study, the granule strength is compared by applying two types of samples, namely commercial iron ore and the gangue-free iron ore prepared from reagents, to both nuclear ore and fine ore granules. The experimental results confirm that gangue components have little effect on the wet compressive strength. However, the dry compressive strength increases with the addition of gangue in the fine ore. Granules of gangue-free fine ore exhibit significantly lower compressive strength. These results are attributed to the difference in the Coulomb repulsion force caused by the zeta potential of the fine ore.</p>

    Eulerian–Lagrangian numerical scheme is applied for analysing packed-bed-structure constructions involving non-spherical solids, such as metallurgical cokes and ferrous ores, and the high-temperature softening characteristics of such beds. 3D scanning is applied for determining the coke and ore shapes, and a multi-sphere discrete element method is used as the functional scheme for non-spherical solid-particle motion tracking. The transient deformation behaviour of the softening ore is simulated using the advanced discrete element method, and the gas permeability characteristics exhibited by the ore shapes in the ironmaking process are discussed. Based on this model, cases with varied softening behaviour represented by the joint spring coefficient are investigated and the effect of the ore-softening behaviour on the gas permeability is evaluated. It is established that the pathway of the passing rivulet depends upon the softening-ore deformation behaviour.

  • Effect of H2 concentration on carbon deposition reaction by CO–H2 gas mixture at 773 K to 973 K Reviewed International journal

    Language:English   Publishing type:Research paper (scientific journal)  

    CO–H2 gas mixture is often used for gas-based DRI process where carbon deposition reaction and Fe3C metal dusting play negative roles for a stable reduction operation. Fe3C decomposition leads to the formation of iron particles which is a catalyst for carbon fiber deposition. Because of the parallel occurrence of these reactions, kinetic analysis of them would be complicated. In the present study, to simplify the kinetic analysis, quantitative analysis of carbon fiber deposition was conducted by using thermobalance. A powdery iron sample was prepared by reduction of Fe2O3 with 100vol%H2 at 673 K. Carbon deposition on the iron sample was investigated under flowing 100%CO, 90vol%CO-10vol%H2, 75vol%CO-25vol%H2, 50vol%CO-50vol%H2, 25vol%CO-75vol%H2 and 10vol%CO-90vol%H2 gas mixtures at 773 K, 873 K and 973 K. Results showed that amount of the deposited carbon in the CO–H2 gas mixture are larger than that in the pure CO gas. The largest amount of deposited carbon was obtained in 75vol%CO-25vol%H2 gas mixture at 873 K. According to SEM observations and weight change measurements, carbon was deposited in fiber shape on the iron surface and amount of it was increased linearly with an increase in sample’s weight change. The rate constant of carbon fiber deposition was calculated considering Rideal mechanism with focusing on elementary reaction steps. It was found that the rate constant of the hydrogen-oxygen reaction step was the largest indicating a significant effect of hydrogen on promoting carbon deposition 773 K and 873 K. This would be due to the removing oxygen from CO by hydrogen on the iron catalyst.

    Currently, low reducing agent operation of blast furnace is actively investigated in order to reduce CO2 emission. However, low reducing agent operation accelerates coke wear, resulting in the decrease in the void fraction in the blast furnace. Particularly, at the dripping zone, the decrement in the void fraction increases the hold-up amount of liquid burden. As a consequence, the gas permeability at the dripping zone becomes lower dramatically. In the present paper, we have focused on the effect of thermophysical properties of molten slags on the gas pressure drop and the liquid hold-up, the measures of the gas permeability, in the counter-current region of gas-liquid flow. It has been considered from the results of hold-up experiments and/or simulations that the surface tensions of molten slags and their contact angles against carbonaceous materials are the most significant properties for the gas pressure drop as well as the liquid hold-up. The previous studies with respect to their properties have been reviewed for the slag compositions and the temperatures close to those at the dripping zone.

    The gasification removal behaviour of phosphorus from high-phosphorus iron ore is theoretically and experimentally studied in the temperature range of 400–900 °C under H2 reducing and N2 atmospheres. In the first step, thermodynamic analysis is conducted to reveal the gasification and reaction behaviours of common phosphorus compounds, namely P4O10, FePO4, AlPO4, Ca2P2O7, and Ca3(PO4)2. The results indicate that P4O10, FePO4, and AlPO4 under H2 reducing atmosphere and P4O10 under a N2 atmosphere can be removed by gasification, and the influence of the interaction between the vaporized gases and iron ore should be investigated. Therefore, dephosphorization experiments are performed on simulated iron ores containing P4O10, FePO4, or AlPO4. For the sample containing P4O10, ferric phosphates and iron phosphides are formed under the N2 and H2 reducing atmospheres, respectively, and their formation rates decreases with decreasing temperature, becoming almost stagnant at 400 °C. Moreover, it is confirmed that FePO4 and AlPO4 cannot be removed even when pure H2 is introduced.

    <p>Slag foaming is a phenomenon caused by the generation of CO bubbles due to the reaction between iron oxide in slag and carbon in pig iron. The purpose of this study is to explore the controlling factors of slag foaming by observing the bubble formation behavior caused by the chemical reaction between iron oxide and Fe-C alloy in slag. 0.06 g of Fe-C alloy was charged to the bottom of the BN crucible, and 6.0 g of slag (SiO<sub>2</sub>:CaO:Fe<sub>2</sub>O<sub>3</sub> = 40:40:30) was charged on top of it. The crucible was placed in an infrared image heating furnace, and the temperature was rapidly raised to 1370°C at a rate of 1000°C/min in a N<sub>2</sub> stream, then held for a predetermined time and rapidly cooled. After rapidly cooling, the internal structure of the sample was observed using a high-resolution X-ray CT device. The spherical equivalent volume is calculated based on the number of bubbles observed and their equivalent circle diameter, and the relationship between the volume ratio of small bubbles in the slag volume and the distance from the bottom of the crucible is calculated, and the bubble density and volume ratio are calculated. It was suggested that the value tends to increase as the distance from the bottom of the crucible increases.</p>

  • Effect of FeO concentration in sinter iron ore on reduction behavior in a hydrogen-enriched blast furnace

    Ohno, K; Maeda, T; Kunitomo, K; Hara, M

    Japan started the national project “COURSE 50” for CO2 reduction in the 2000s. This project aimed to establish novel technologies to reduce CO2 emissions with partially utilization of hydrogen in blast furnace-based ironmaking by 30% by around 2030 and use it for practical applications by 2050. The idea is that instead of coke, hydrogen is used as the reducing agent, leading to lower fossil fuel consumption in the process. It has been reported that the reduction behavior of hematite, magnetite, calcium ferrite, and slag in the sinter is different, and it is also considerably influenced by the sinter morphology. This study aimed to investigate the reduction behavior of sinters in hydrogen enriched blast furnace with different mineral morphologies in CO—CO2—H2 mixed gas. As an experimental sample, two sinter samples with significantly different hematite and magnetite ratios were prepared to compare their reduction behaviors. The reduction of wustite to iron was carried out at 1000, 900, and 800°C in a CO—CO2—H2 atmosphere for the mineral morphology-controlled sinter, and the following findings were obtained. The reduction rate of smaller amount of FeO led to faster increase of the reduction rate curve at the initial stage of reduction. Macro-observations of reduced samples showed that the reaction proceeded from the outer periphery of the sample toward the inside, and a reaction interface was observed where reduced iron and wustite coexisted. Micro-observations revealed three layers, namely, wustite single phase in the center zone of the sample, iron single phase in the outer periphery zone of the sample, and iron oxide-derived wustite FeO and iron, or calcium ferrite-derived wustite ‘FeO’ and iron in the reaction interface zone. A two-interface unreacted core model was successfully applied for the kinetic analysis of the reduction reaction, and obtained temperature dependent expressions of the chemical reaction coefficients from each mineral phases.

    <p>Negative effect from low coke rate operation at cohesive zone is obvious because it makes thinning of coke slit thickness. Correct knowledge about gas permeability of cohesive layer is becoming more and more important. In order to precisely understand cohesive behaviour, a softening and melting simulator under rapid heating and quenching conditions was applied for clarify a determinant factor of gas permeability behaviour. To focus on softening and melting behaviour, granulated slag particle bed layer without iron oxide was prepared as packed bed sample layer can show softening and melting. The packed bed slag samples in graphite crucible were rapidly heated up to 1200°C, and then gradually heated up to 1500°C with 10°C/min under inert gas atmosphere and 0.1 MPa load. Gas pressure drop and shrinkage degree of the sample layer were measured during the softening and melting test, and quenched sample was made at certain temperature when the maximum gas pressure drop was measured. The CT observation of the quenched sample provided 3D shape information of gas path shape in sample packed bed. Gas pressure drop was estimated with fanning's equation with the gas path information. The estimation values were shown positive correlation with measured maximum pressure drop. The CT observation also gave triple line length among molten slag, graphite, and gas. Combination the triple line length and molten slag surface tension could use for evaluation of static force balance when maximum pressure drop obtained.</p>

    低炭素高炉操業すなわち炭材比、コークス比の大幅低減時には、コークス層厚が低減し炉内の通気性、通液性の変化が予測され、これにより固気液の流れ、接触状況が一変し、生産性の低下を招くことが懸念される。低コークス比操業では従来の半径方向のガス、液の流れ制御などの技術では諸問題に対応できないことが予測される。今後、極限的な低炭素高炉を実現するために、予熱、還元、溶融の要素現象に関し、新しい概念に基づく基礎的なアプローチを検討する。
