Abstract:

Abstract Several samples of dusts from steel and coke plants (collected mostly with electro filters) were subjected to the investigation of content of mineral phases in their particles. Additionally, sample of bog iron ore and metallurgical slurry was studied. Next, the magnetic susceptibility of all the samples was determined, and investigations of iron-containing phases were performed using transmission Mössbauer spectrometry. The values of mass-specific magnetic susceptibility χ varied in a wide range: from 59 to above 7000 × 10−8 m-3·kg−1. The low values are determined for bog iron ore, metallurgical slurry, and coke dusts. The extremely high χ was obtained for metallurgical dusts. The Mössbauer spectra and X-ray diffraction patterns point to the presence of the following phases containing iron: hematite and oxidized magnetite (in coke and metallurgical dusts as well as metallurgical slurry), traces of magnetite fine grains fraction (in metallurgical dusts), amorphous glassy silicates with paramagnetic Fe3+ and Fe2+ ions, traces of pyrrhotite (in coke dusts), α-Fe and nonstoichiometric wüstite (in metallurgical slurry), as well as ferrihydrite nanoparticles (in bog iron ore). For individual samples of metallurgical dusts, the relative contributions of Fe2+/3+ ions in octahedral B sites and Fe2+ ions in tetrahedral A sites in magnetite spinel structure differs considerably.

Abstract:

The coke reactivity is one of the major evaluation indexes of coke. But there is still no clear statement on the reaction temperature as well as the way of reaction. In order to have a further understanding on the process of coke solution loss reaction in the blast furnace, the present paper studied the coke reactivity at different temperatures and finally found out the reaction rules and constraints in different zones of the blast furnace.

Abstract:

Macerals in coal are of different types: reactive and inert. These macerals are differ in their physical and chemical properties. Column flotation method has been used to separate the reactive macerals in a non-coking coal. The enriched coal is then characterized in order to understand the changes in the coking potential by different techniques. It is then used in making of metallurgical coke by proper blending with other coals. Enriched coal enhance the properties of metallurgical coke. This shows a path of utilization of non-coking coal in metallurgical coke making.

Abstract:

At foundry coke production, introduction into a coal burden comparatively small amount of non-sintering carbonaceous additives is one of effective methods of the coke mechanical, physical and chemical properties intended control. A review of industrial tests on coal burdens coking with different thinning additives, carried out at coking plants of Western Siberia and the Urals, presented. Coke dust of coke dry quenching facility was used as additives, as well as oil-coke and semi-coke fines, and rubber crumb. Under industrial conditions of JSC “Altaj-koks” and JSC “Koks” coke dust of coke dry quenching facility was tested as a thinning additive. After introduction into the burden of 1.6–3.0% of coke dry quenching facility dust, the coarseness and mechanical strength of foundry coke increased. The industrial burden coking with oil-coke fines was accomplished at JSC “Altajkoks” Nos 1 and 2 coke-oven batteries. Oil-coke fines in the amount of 5% was added to a burden (у = 15–16 mm) without change of coking regime (the period of coking is 15–16 h). Strength of foundry coke (М40) increased by average 0.5%, of BF coke – by 1.2%, ash content decreased by 0.3%, sulfur content increased by 0.03–0.06%, reaction ability decreased by 19% (rel.). At the OJSC “Gubakhinsky koks” it was determined by industrial tests, that it is possible to produce a metallurgical coke, meeting requirements of non-ferrous metallurgy, providing up to 5% of oil-coke fines are added instead of the same amount of low-sintering coals. VUKHIN’ studies showed, that still higher effect in improving foundry and BF coke quality can be reached by introducing into the coal burdens “modified” oil coke up to 50% as a coking additive. During industrial tests at JSC “Altaj-koks” semi-coke fines were introduced into production burden instead of KCH coal in the amount of 3–7%. At its utilization a burden crushing degree decreased down to 76.5%, dust content (class 0.5–0 mm) decreased down to 39.1%, its bulk density increased up to 780 kg/m3 . At that the coke mechanical strength corresponds to that for coke made of industrial burden, and its coarseness increased. Results of successful industrial tests of foundry coke made of burdens with coke dry quenching facility dust and oil coke fines at smelting in cupola gray cast iron and malleable cast iron.

Abstract:

Charcoal is an interesting reducing agent because it is produced from biomass which is renewable and does not contribute to global warming, provided that there is a balance between the felling of timber and growth of trees. Biocarbon is a promising alternative to fossil reductants for reducing greenhouse gas emissions and increasing sustainability of the metallurgical industry. In comparison to conventional reductants (i.e., petroleum coke, coal and metallurgical coke), charcoal has a low density, low mechanical properties and high CO2 reactivity, which are undesirable in ferroalloy production. Densification is an efficient way to upgrade biocarbon and improve its undesirable properties. In this study, the deposition of carbon from methane on three types of charcoal has been investigated at 1100 °C. CO2 reactivity, porosity and density of untreated and densified charcoal were measured, and results were compared to metallurgical coke. Surface morphology of the charcoal samples was investigated by using scanning electron microscopy (SEM). SEM confirmed the presence of a deposited carbon layer on the charcoal. It was found that the CO2 reactivity and porosity of charcoals decreased during the densification process, approaching that of fossil fuel reductants. However, the CO2 reactivity kept higher than that of metallurgical coke.

Abstract:

Metallurgical coke in the blast furnace provides a permeable matrix through which reducing gases may ascend and molten materials descend. A lack of permeability will inevitably lead to a poor gas distribution and result in a reduction of the furnace output and efficiency.A decrease in the permeability of the carbonaceous coke matrix arises when changes induced by the blast furnace environment occur in the properties of the material and effect the matrix voidage by causing a reduction of coke strength. A major influence of change within the blast furnace is the presence of recirculating alkali, particularly potassium, which is known to induce considerable microstructural changes (enhanced localised ordering), within the metallurgical coke. These microstructural changes lead to structural weakening as a consequence of a variety of factors:-

Abstract:

At present, the excess capacity in China’s coke industry can be deployed to utilize some low-rank coal, replacing coking coal with potential economic gains, energy efficiency, and environmental benefits. This study presents a life cycle analysis to model these potential benefits by comparing a metallurgical coke technical pathway with technical pathways of gasification coke integrated with different chemical productions. The results show that producing gasification coke is a feasible technical pathway for the transformation and development of the coke industry. However, its economic feasibility depends on the price of cokes and coals. The gasification coke production has higher energy consumption and CO2 emissions because of its lower coke yield. Generally speaking, using gasification coke to produce F-T oils has higher economic benefits than producing methanol, but has lower energy efficiency and higher carbon emissions.

A new method of the estimation of influence of the iron ore materials and coke metallurgical properties on the efficiency of blast furnace smelting is developed. It consists in the following stages: the laboratory tests with the definition of the iron ore materials and coke metallurgical properties; the analytical study of the influence of these characteristics on the efficiency of blast furnace smelting using by mathematical models; the experimental industrial and industrial tests. The developed methodological basis allows to obtain improved criteria for evaluating the metallurgical characteristics of the raw materials and to explain the mechanism of their effect on the reaction of the direct and indirect recovery in the blast furnace. Therefore it allows to formulate recommendations to improve the blast furnace smelting technology.

Abstract:

The blast furnace coke plays four roles as exothermic agent, reducer, carburizer and framework. The former three roles can be played by other fuels, but the role as framework still can’t be played by other fuels by now. In order to ensure its skeleton role, it must be sure that the coke has enough high-temperature strength. This research uses KSJ decarbonizing electric furnace, drum-I and high temperature compressive testing machine to furthest simulate the coke’s actual actions in the blast furnace. The research indicates that comparing with the reactivity and strength index after reaction of coke GB4000-1996, the blast furnace coke’s high temperature compressive strength under a certain temperature and a certain carbon loss rate can give a more comprehensive evaluation of the quality of coke.

Abstract:

Six different particle size distribution (Gates–Gaudin–Schuhmann (GGS), Rosin–Rammler (RR), Lognormal, Normal, Gamma, and Swebrec) models were compared under different metallurgical coke grinding conditions (ball size and grinding time). Adjusted R2, Akaike information criterion (AIC), and the root mean of square error (RMSE) were employed as comparison criteria. Swebrec and RR presented superior comparison criteria with the higher goodness-of-fit and the lower AIC and RMSE, containing the minimum variance values among data. The worst model fitting was GGS, with the poorest comparison criteria and a wider results variation. The undulation Swebrec parameter was ball size and grinding time-dependent, considering greater b values (b > 3) at longer grinding times. The RR α parameter does not exhibit a defined tendency related to grinding conditions, while the k parameter presents smaller values at longer grinding times. Both models depend on metallurgical coke grinding conditions and are hence an indication of the grinding behaviour. Finally, oversize and ultrafine particles are found with ball sizes of 4.0 cm according to grinding time. The ball size of 2.54 cm shows slight changes in particle median diameter over time, while 3.0 cm ball size requires more grinding time to reduce metallurgical coke particles.

Abstract:

During the research, rolled scale and gas cleaning slimes from oxygen-converter workshop No. 1 of JSC “EVRAZ ZSMK” were used as iron-oxide-containing materials. Semi-coke from brown coals of the Berezovskoye deposit of the Kansko-Achinsk basin (temperature of semi-coking is 750 °C), coke fines of PJSC “Coke” and dust from coke dry-quenching plant of JSC “EVRAZ ZSMK” were used as carbon reducing agents. Total iron, FeO and Fe2 O 3 oxides amount to 73.3, 75.5 and 20.9 % in scale, 41.2, 4.7 and 53.7 % in sludge, respectively. Sludge also contains 4.3 % of total carbon and 20.6 % of CaO. Brown-coal semi-coke, coke fines and coke dust contains carbon and volatiles 94.05 and 9.5 %, 97.50 and 2.1 %, 97.47 and 1.6 % on dry ashless weight, respectively. For metallization of furnace charges with composition: scale, slime–semi-coke, coke fines, dust with addition of 10 % water-soluble binding–molasses, strong unroasted briquettes were pressed. Metallization modes of analyzed charge compositions were thermodynamically predicted and technologically determined. Metallization degree and metal iron content at usage of brown-coal semi-coke were found to be 97.5 and 90.2 % for scale, 97.5 and 71.3 % for sludge; of coke fines: 70.7 and 61.9 % for scale, 68.9 and 48.4 % for sludge; of coke dust: 72.1 and 62.6 % for scale, 69.2 and 48.2 % for sludge. The possibility of achievement the metallization degree of 97.0 – 98.0 % was established for briquetted charge from scale – brown-coal semi-coke with 92.0 – 93.0 % of total iron, 89.8 – 90.6 % of metallic iron, 2.8 – 3.2 % of FeO, 0.06 – 0.08 % of S, 0.016 – 0.018 % of P, 1.7 – 1.9 % of C, 1.0 – 1.2 % of CaO and 0.25 – 0.35 % of MgO at 1173 K and duration of 40 min.

Abstract:

AbstractIn this paper, the effects of temperature and atmosphere on the gasification reaction of ferro-coke were investigated in consideration of the actual blast furnace conditions. Besides, the microstructure of the cokes was observed by scanning electron microscope (SEM). It is found that the weight loss of ferro-coke during the gasification reaction is significantly enhanced in the case of increasing either the reaction temperature or the CO2 concentration. Furthermore, compared with the normal type of metallurgical coke, ferro-coke exhibits a higher weight loss when they are gasified at the same temperature or under the same atmosphere. As to the microstructure, inside the reacted ferro-coke are a large amount of pores. Contrary to the normal coke, the proportions of the large-size pores and the through holes are greatly increased after gasification, giving rise to thinner pore walls and hence a degradation in coke strength after reaction (CSR).
