  • Society, Materials, and the Environment: the Case of Steel
    metals Review Society, Materials, and the Environment: The Case of Steel Jean-Pierre Birat IF Steelman, Moselle, 57280 Semécourt, France; [email protected]; Tel.: +333-8751-1117 Received: 1 February 2020; Accepted: 25 February 2020; Published: 2 March 2020 Abstract: This paper reviews the relationship between the production of steel and the environment as it stands today. It deals with raw material issues (availability, scarcity), energy resources, and generation of by-products, i.e., the circular economy, the anthropogenic iron mine, and the energy transition. The paper also deals with emissions to air (dust, Particulate Matter, heavy metals, Persistant Organics Pollutants), water, and soil, i.e., with toxicity, ecotoxicity, epidemiology, and health issues, but also greenhouse gas emissions, i.e., climate change. The loss of biodiversity is also mentioned. All these topics are analyzed with historical hindsight and the present understanding of their physics and chemistry is discussed, stressing areas where knowledge is still lacking. In the face of all these issues, technological solutions were sought to alleviate their effects: many areas are presently satisfactorily handled (the circular economy—a historical’ practice in the case of steel, energy conservation, air/water/soil emissions) and in line with present environmental regulations; on the other hand, there are important hanging issues, such as the generation of mine tailings (and tailings dam failures), the emissions of greenhouse gases (the steel industry plans to become carbon-neutral by 2050, at least in the EU), and the emission of fine PM, which WHO correlates with premature deaths. Moreover, present regulatory levels of emissions will necessarily become much stricter.

Abstract The iron and steel industry accounts for 5 % of worldwide CO2 emissions. With 13 MtCO2eq annually, TATA Steel, which employs the traditional blast furnace – basic oxygen furnace steel making route, is one of the largest single point emitters in the Netherlands (and EU). Given the role of steel in present and future society, decarbonizing the steel industry is of paramount importance for a CO2 net-zero society.

The end goal is that of highlighting the steelworks’ main hot spots and identifying potential options for environmental improvement. The development for such an analysis is based on a Life Cycle Assessment (LCA) of steel production with a cradle to casting plant gate approach that covers the stages from raw material extraction to solid steel slab production. The inventory results have highlighted the large solid waste production, especially in terms of slag, which could be reused in other industries as secondary raw materials. Other reuses, in accordance with the circular economy paradigm, could encompass the energy waste involved in the steelmaking process. The most burdening lifecycle phases are the ones linked to blast furnace and coke oven operations.

  • PPT Engineeringcompany Has Been Designing and Developing The
    METALLURGY PT Engineering company has been designing and developing the program of electro-hydraulic systems Pin metallurgy ever since 1976, practically since its founding. Since then, until the present day, the company has been constantly improving its design solutions in order to bring them into line with the latest requirements of technology, quality and reliability. Manufacturing of electro-hydraulic systems for process equipment for production of coke in metallurgical plants is the most important segment of PPT Engineering’s presence in metallurgy. Electro-hydraulic systems for coke machines are designed to provide sequential movement of mechanisms on pertaining machines during one work cycle on a coke battery. The task is accurate positioning of cylinders as actuation elements of mechanisms, which are designed for large external loads. The specific feature of electro-hydraulic systems for coke equipment is 20 to 25 individual actuation systems on one machine with central hydraulic suplly, whereby the desired flow and pressure, being the basic parameters of actuation systems, are provided for each mechanism. Electro-hydraulic systems are installed in the following plants: • In cold and hot rolling mills for production and transport of sheet metal, profiles, wire, rods, beams, pipes, elbows etc. (furnaces, traction benches for pipes, winders, shears, presses...) • For blast furnace serving (drilling machine, manipulator and hydrostatic clay gun) • For serving in coke ovens (dosing coaches, coke pusher cars, door extractors, coke guide cars and coke quenching cars and locomotive for hauling wagons for coke quenching) Some of the most importand references are: • Manufacturing of hydraulic blocks for Dave McKoy company, for the requirements of Železara (Ironworks) Smederevo • Manufacturing of complete hydraulic system for roll stand no.

  • Riduzione Diretta Use of Dri/HBI in Ironmaking and Steelmaking Furnaces
    Riduzione diretta use of drI/HBI in ironmaking and steelmaking furnaces c. di cecca, S. Barella, c. Mapelli, A. F. ciuffini, A. Gruttadauria, d. Mombelli, E. Bondi The iron and steel production processes are characterized by a considerable environmental impact. The reduction of this impact, in particular emissions, is the target of modern society; this goal can be achieved through process optimization. The two main production processes, the blast furnace one and the one from electric arc furnace, are of different specificities and therefore different levers are present in order to decrease the amount of pollutants in the atmosphere. The adoption of pre reduced iron charge for these processes seems to be a good operating practice. A further reduction of pollutants linked to the coke oven batteries can be carried out thanks to the reduction of loaded cast iron within the converter. The decrease of the hot charge means that a lower amount of coal is consequently required. The electrical cycle, due to its structure, has a lower environmental impact, but the maximization of the process yield is a desirable objective for the purpose of a reduction of the environmental impact and economic optimization of such a steel cycle. The direct-reduced iron (DRI), due to its operative flexibility, is a suitable element to achieve this target.

Received: 19 October 2018; Accepted: 21 November 2018; Published: 27 November 2018 Abstract: Recently, increasing attention has been paid to alternative ironmaking processes due to the desire for sustainable development. Aiming to develop a new direct reduction technology, the paired straight hearth (PSH) furnace process, the carbothermic reduction of ore-coal composite pellets in a tall pellets bed was investigated at the lab-scale in the present work. The experimental results show that, under the present experimental conditions, when the height of the pellets bed is 80 mm (16–18 mm each layer, and 5 layers), the optimal amount of carbon to add is C/O = 0.95. Addition of either more or less carbon does not benefit the production of high quality direct reduced iron (DRI). The longer reduction time (60 min) may result in more molten slag in the top layer of DRI, which does not benefit the actual operation. At 50 min, the metallization degree could be up to 85.24%. When the experiment was performed using 5 layers of pellets (about 80 mm in height) and at 50 min duration, the productivity of metallic iron could reach 55.41 kg-MFe/m2·h (or 75.26 kg-DRI/m2·h).
