The article presents the results of development of an information modeling system for movement of charge layers and melt accumulation in a blast furnace well. The work is based on mathematical models reflecting modern ideas on the course of physico-chemical phenomena of blast furnace melting and technological features of the blast furnace process. The use of such system makes it possible to determine and visualize the configuration of layers of iron ore materials and coke according to the working space height, taking into account a given ore load in equal-sized annular zones of the blast furna

Significant amounts of dust from the processing of cast iron in the furnace can be considered as by-products for the technological flow from the agglomeration, having an adequate chemical and structural composition. Blast furnace dust contains significant amounts of metals and non-metals that can be recovered by various processing methods. The transformation of these recyclable materials for reuse into metal producing units is essential not only for the conservation of mineral resources but also for the protection of the environment.

The mechanism of capture of metal drops by the slag melt was investigated using blast furnace slag as an example. The role of the viscosity of the blast furnace slag in reducing iron loss at the output from the blast furnace is shown. Reducing the viscosity of slags contributes to the rapid settling of small drops of cast iron in the slag volume. It is noted that the CaO/SiO2 ratio is an important parameter that changes the viscosity of blast furnace slag. To ensure the minimum viscosity of blast furnace slag, it is necessary to establish the optimal chemical composition of the slag, in partic

The control of blast furnace hearth lining is of critical importance in ensuring efficient and safe operation of blast furnace production process. Hearth lining plays a fundamental role in protecting the blast furnace walls from high temperatures and chemically aggressive slag melt. Early detection of high wear areas allows planning of preventive maintenance, thereby minimizing downtime and lost productivity. Furthermore, it contributes to the efficient use of resources by optimizing the replacement of damaged lining sections, thus avoiding unnecessary expenditure on preventive measures. The p

The aim of the work is to develop physicochemical bases for predicting the technological properties of finite blast furnace slags, algorithmic and software for the subsystem for diagnosing the slag regime of blast furnace smelting. Based on experimental data on the properties of natural finite blast furnace slags, predictive models for calculating the viscosity of the final slag at a temperature of 1400-1550 °C were improved by including in the model structure an integrated slag melt index of the parameter Δe, which reflects the individual effect.

The blast furnace is a large metallurgical vertical furnace for smelting cast iron and ferroalloys. The principle of the blast furnace operation is the continuity of the metallurgical process during the whole period of its operation up to the regular overhaul, which is performed on average once every ten years. The total service life of the blast furnace can exceed one hundred years. The blast furnace is of a mine type: it is periodically charged from above with ore, coke and other components, gas being fed from below.

Abstract Using coals to produce coke, a fuel and reducing agent for metallurgical processes, is the second-largest application of coals, though small compared to the electricity market. Many bituminous coals soften, swell, and then resolidify when heated. The product is metallurgical coke, used worldwide in blast furnaces to produce iron. Producing a tonne of iron today requires only one-third the amount of coke used years ago, thanks to improvements in furnace technology. In the furnace, coke must react readily with the air blast, generate temperatures high enough to melt iron and slag, and y

Bloomery forges could not produce cast items such as hollowware, potash kettles, or the hammerheads and anvil bases artisans needed for their forges. With a blast furnace, an ironmaker could both increase the scale of iron smelting and provide customers with iron castings. However, in colonial times a furnace required an investment of over £3,000, while a fully equipped bloomery forge cost only about £500. Additionally, blast furnace proprietors had to assemble a workforce at least ten times larger than they would need for a bloomery, provide a continuous supply of ore and fuel over a period o

Salisbury’s particular combination of natural resources allowed iron- making to continue for nearly 200 years from its 1736 start. In the first hundred years of mining and smelting, the district’s entrepreneurs had established a place for themselves in the national market for high-quality iron products while they managed their mineral, waterpower, and forest resources to meet the demands of expanded production. Each resource offered different challenges. An ironmaker could cut wood without thought of replacement or could manage woodland for sustained yield. As miners dug deeper for ore, they h

Then a new generation of entrepreneurs with both artisanal and managerial skills began making and selling sophisticated products to distant as well as local customers.

Coke oven gas (COG) is a by-product of the coke making process. In the steelmaking industry, COG is often injected along with natural gas as fuel into blast furnace to replace coke for cost reduction. For an integrated steel plant, NG is always more expensive than COG. Especially, NG is purchased externally, and COG is generated internally. To lower the total fuel cost, the operators always try to maximize COG usage and only use NG as supplement for thermal control.
