Liberty Steel Group, part of GFG Alliance, announced that it made a non-binding indicative offer (NBIO) as part of a thyssenkrupp-led process to acquire the steel activities of thyssenkrupp. Liberty Steel, a global steel and mining business, has 30,000 employees in more than 200 locations on four continents. A possible combination of Liberty Steel and thyssenkrupp Steel would create a group well positioned to tackle the challenges faced by the European steel industry.
Cleveland-Cliffs Inc. entered into a definitive agreement with ArcelorMittal S.A. pursuant to which Cleveland-Cliffs will acquire substantially all of the operations of ArcelorMittal USA LLC and its subsidiaries for approximately $1.4 billion. Upon closure of the transaction, Cleveland-Cliffs will be the largest flat-rolled steel producer in North America, with combined shipments of approximately 17 million net tons in 2019.

ArcelorMittal announced its intention to build an electric-arc furnace (EAF) steelmaking facility at AM/NS Calvert in Alabama. Once completed, the planned facility will be capable of producing 1.5 million tons of steel slabs annually for the hot-strip mill. It will also produce a broad spectrum of steel grades required for Calvert’s end-user markets. Construction is expected to take 24 months, and the new facility is anticipated to create 300 new jobs.
SMS Concast will supply two eight-strand billet casters for Yongfeng Lingang’s newly built basic oxygen furnace (BOF) steelmaking plant in Linyi City, China. The two casters will have a combined production capacity of approximately 2.6 million tons per year of steel bars. Both casters will have a radius of 10.25 meters (33.6 feet). While the first caster will produce on eight strands right from the beginning, the second one will initially be equipped with seven strands but prepared for the addition of an eighth strand in the future. Both machines will cast billets of 165 mm (6.5 inches) square.
Unavoidable by-products of the steelmaking process, nonmetallic inclusions in steel have been a focus of the industry for over a century.

Researchers at Carnegie Mellon University’s (CMU) Center for Iron and Steelmaking Research are bringing computer-vision and machine-learning techniques to the study of inclusions, hoping to increase the efficiency of inclusion analysis and gain new insights.
Ovako, together with Linde Gas AB, conducted a full-scale trial using hydrogen to heat steel before rolling. The trial was performed with good results in one of the company’s pit furnaces at the Hofors rolling mill in Sweden. This historic development for the steel industry proves that carbon dioxide emissions from rolling can be eliminated provided the right financial support and infrastructure are in place.
Cleveland-Cliffs Inc. successfully completed the acquisition of AK Steel Holding Corp., integrating North America’s largest producer of iron-ore pellets downstream into the production of value-added steel and specialty manufactured parts for the automotive industry. The combined company will be led by Chairman, President and CEO Lourenco Goncalves. It combines mining, pelletizing, direct-reduction, EAF steelmaking, BF/BOF steelmaking, highly technologically developed finishing mills and automated manufacturing of auto parts.
Jingye Group, a Chinese steelmaker, acquired British Steel’s facilities in the U.K. and the Netherlands, a move that will secure approximately 3,200 jobs. Jingye will invest approximately $1.5 billion in the business. Initiatives include: the development of an electric-arc furnace (EAF) in Teesside; the construction of a new 250-MW power plant to serve the Scunthorpe site; investment in the rolling mills to produce high-quality steel products; the construction of a new rebar line; and enhancing the current rail mill.
Saarstahl AG successfully commissioned a new five-strand billet caster at its steel plant in Völklingen, Germany. The caster, supplied by SMS Concast, a member of SMS group, is designed for a nominal annual production of 850,000 tons and the casting of 180-mm-square billets. According to SMS Concast, the casting machine at Saarstahl is the first caster in the world designed with mechanical soft reduction (MSR) technology for a billet cross section of 180 mm (7 inches) square. It produces billets in a wide range of steel grades, including bearing steel, spring steel, cold-heading and free-cutting steels.
United States Steel Corp. plans to reduce greenhouse-gas-emissions intensity across its global footprint by 20%, as measured by the rate of carbon dioxide (CO2) equivalents emitted per ton of finished steel shipped, by 2030 based on 2018 baseline levels. This target will apply to U.S. Steel’s global operations. The company plans to achieve this goal through multiple initiatives, including the development of electric-arc furnace (EAF) steelmaking at its Fairfield Works and at Big River Steel, in which U.S. Steel recently acquired a minority interest with an option to acquire the remainder over the next four years.
