This appointment is regarded as the founding of what is now the Institute of Iron and Steel Technology. Among the 260 years of TU Freiberg's history, approximately 150 years have been dedicated to pioneering research and teaching in ferrous metallurgy, establishing the institute as a center of innovation in this field.</p><p>Today, the Institute of Iron and Steel Technology is one of the few institutions in Europe, along with <i>RWTH Aachen</i> (Germany), <i>MU Leoben</i> (Austria), <i>KTH</i> (Sweden), the <i>University of Oulu</i> (Finland), <i>TU Delft</i> (Netherlands), and <i>KU Leuven</i> (Belgium), which still provide extensive education and research in iron and steel technology. It has become a trusted partner of German and European industry, contributing significantly to advances in climate-neutral steel production, greenhouse gas reduction, and the circular economy. The institute offers specializations in ferrous metallurgy through its German diploma and master's programs in <i>Materials Science and Technology</i>. Since 2018, it has expanded its offerings to include English-language master's programs in <i>Metallic Materials Technology</i> and <i>Technology and Application of Inorganic Engineering Materials</i>, enhancing its international reach.</p><p>The Institute of Iron and Steel Technology is equipped with two technical facilities: a melt shop and a heat treatment shop, as well as three laboratories specializing in metallography, analytical methods, and thermophysical properties. The melt shop features a variety of advanced equipment, including vacuum induction melting and casting furnaces, high- and medium-frequency induction furnaces, an electroslag remelting unit, atomization systems for metal powder production, and a cold crucible induction furnace. In 2018, the Vacuum Induction Melting furnace (VIM12) was upgraded with a vacuum casting chamber and a casting simulator, enabling simulations of conditions in continuous casting molds. In 2020, the H<sub>2</sub> retort for reducing iron oxide carriers was upgraded with precision balances and gas mass spectrometers. Further advancements followed in 2022, with the addition of EIGA (Electrode Inert Gas Atomization) technology to the VIGA (Vacuum Inert Gas Atomization) unit, allowing refractory metals to be atomized at temperatures up to 2400 °C.

Steel production from iron ore is energy intensive and emits approximately double the amount of carbon dioxide per ton of steel produced. On the other hand, the carbon dioxide emission intensity for steel production from recycled scrap is only about 0.35 tons of carbon dioxide per ton of steel. Hence, crude steel production through the scrap route is gaining momentum. However, the steel production from iron ore is expected to keep growing as many countries have their per capita steel consumption well below the world average. This calls for the global steel community to explore the possibilities of modifying the existing processes as well as to look for novel process routes that can make steel production more sustainable. India, being the second largest steel producer in the world now, has drawn a roadmap to drive the steel industry towards the net zero target by 2070. Steel plants, globally, including those in India, are actively looking for sustainable solutions. Further, digital tools such as AI/ML are also being leveraged to improve the existing steel production practices. Keeping these in focus, the 4th International Conference on Science and Technology of Ironmaking and Steelmaking (STIS-2022) was organized by the Centre of Excellence in Steel Technology (CoEST), Department of Metallurgical Engineering and Materials Science, Indian Institute of Technology Bombay at IIT Bombay from 13th–16th December 2022. The conference was supported by the Indian Institute of Metals (IIM) and the Association of Iron and Steel Technology, USA (AIST). This series of conferences, an Indian initiative, provides a platform for the global steel community consisting of academicians, researchers, industrial experts, technology providers, students, etc. to discuss and deliberate on innovative approaches and solutions.</p><p>There were 115 presentations during the conference. In addition, two panel discussions were also organized: 1) Digitalization in the steel industry and 2) Decarbonization of the steel industry. The conference had an active participation from the academia as well as the steel industry. The presentation topics spanned from agglomeration of iron ore to continuous casting. The authors submitted short manuscripts which were reviewed by a pool of leading researchers in the field. The reviewed short manuscripts were published in the conference proceedings. Based on the reviewers’ feedback, a few authors were invited to submit full manuscripts to be considered for publication in the Steel Research International. These manuscripts were reviewed and considered for publication in the Steel Research International as per the standard reviewing practice of the journal.

It is widely known that the flow of molten steel through a shroud, with or without inert gas injection, can influence the flow behavior in the tundish and, consequently, the hydrodynamic performance. However, large throughput rates may promote refractory wear, slag entrainment, and large tundish eye, which are known to seriously impair steel cleanliness, implying a severe need for optimization of the inert gas injection rate into the ladle shroud. In this study, two distinct reduced scale slab-casting tundishes (from different plants) with scale factors of 0.35 and 0.40 fitted with various flow modifiers are considered. Experiments are performed considering gas-to-liquid loading ratios of 10, 20, and 30%. An improved tundish hydrodynamic performance is observed during the experiments, which is validated with numerical modeling results using ANSYS Fluent 2021R1. Although gas injection to the shroud certainly enhances the hydrodynamic performance of tundishes, the effect fades away beyond 20% of the gas-to-liquid loading ratio, regardless of the tundish design, capacity, and different flow modifiers used.</p>","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
