Tenova started up what it says is the most productive electric-arc furnace (EAF) in history at Acciaieria Arvedi in Cremona, Italy, in September 2020. The Consteel EAF replaced an existing Consteel furnace that was originally installed in 2008. It has a tapping size of 300 metric tons and is designed to reach a power-on time of 37 minutes with a charge mix including up to 30% HBI or other scrap substitutes. The EAF has a 9.1-meter-diameter shell and is continuously fed by a 4-meter-wide slip-stick conveyor. It is also equipped with a state-of-the art automation package.
Danieli received an order from Russian steelmaker OMK for a direct reduction plant that will include an electric-arc furnace (EAF) and direct reduced iron (DRI) technology. Part of a new melt shop at the Vyksa Steel Works, it will produce 2.5 million tons per year of slabs, seamless pipe and rail wheels. According to Danieli, it will be the largest single-module direct reduction plant in Russia. The facility will utilize Danieli’s Energiron DRI technology, which allows the processing of a wide range of iron-oxide pellet qualities and includes ultra-low-NOx burners.
Liberty Steel Group (LSG), part of GFG Alliance, acquired the strategic French steel assets of France Rail Industry business (Hayange) and the Ascoval steelworks. Hayange, located in Moselle, manufactures a range of steel rails for nationally significant infrastructure clients, including France’s national rail operator and the operator of Paris’ metro system. The site, which employs around 430 people, produces over 300,000 metric tons of rail per year. Ascoval, based in Saint-Saulve in northern France, has approximately 270 employees. The plant uses electric-arc furnace (EAF) technology and has the capability to produce 600,000 metric tons of steel blooms, billets and other forged products annually from recycled scrap metal. Ascoval will use recycled steel to supply Hayange, creating an integrated French GREENSTEEL rail business.
Commercial Metals Company (CMC) announced plans to build a $300 million micro-mill in Mesa, Ariz. According to CMC, the facility will be the first in the world to produce merchant-bar-quality (MBQ) products through a continuous-continuous production process. It will allow CMC to more efficiently meet West Coast demand for rebar and MBQ products. The micro-mill, CMC’s third such facility, is expected to start up in early 2023 and employ approximately 185 people. It will achieve an estimated nominal annual capacity of 500,000 tons, including 150,000 tons of merchant product.
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.
American Resources Corp. announced the expansion of its wholly owned subsidiary, American Metals LLC, and the selection of its currently owned Deane Mining facility in Letcher County, Ky., as its initial rail load-out and logistics location for processed metals. American Metals is expanding its current metal-recovery business and will aggregate, process and transport used steel to be recycled and sold to traditional and electric-arc-furnace (EAF) steelmaking facilities. The company will utilize the existing infrastructure at its Deane Mining facility, which has the ability to haul and aggregate metal from a range of locations.
Air Liquide signed a long-term agreement with Steel Dynamics Inc. (SDI) to supply gaseous oxygen, nitrogen and argon to SDI’s electric-arc furnace (EAF) steel mill in Sinton, Texas. To support the agreement, Air Liquide plans to invest over $100 million to install an air-separation unit (ASU) on its Gulf Coast pipeline network in Ingleside, Texas, and extend its pipeline network to SDI’s site.
GFG Alliance (GFG) will add an electric-arc furnace (EAF) and a direct reduced iron (DRI) facility to Whyalla, its South Australian-based steelworks. The EAF will utilize the latest technology for energy optimization, and the DRI facility will produce low-emission Greensteel from GFG’s South Australian magnetite resource and domestic steel scrap. These investments, along with previously announced plans for a new rolling mill to be built by Danieli, are part of GFG’s updated Whyalla Greensteel Transformation Plan.
JM Steel announced that it will be part of Steel Dynamics’ new flat-roll steel mill in Sinton, Texas – a move that will substantially expand JM Steel’s footprint over the next two years. The facility, scheduled to be operational in June 2021, will have an estimated annual capacity of 3.0 million tons and include next-generation electric-arc furnace (EAF) technology. JM Steel's facility has plans to include three slitting lines capable of producing 30,000 tons of steel per month. It will also include two roll-forming lines and a stamping press capable of producing 260,000 bolts per month to serve mining markets in Mexico, Honduras, Costa Rica, Chile and Peru.
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.
