United States Steel Corp. executed a non-exclusive memorandum of understanding (MOU) with Equinor US Holdings Inc., an affiliate of Norway-based Equinor ASA. Under the MOU, the companies will study the potential for carbon capture and storage (CCS) and hydrogen development in the tristate region of Ohio, Pennsylvania and West Virginia. Hydrogen-based steel processes and CCS are among the more promising and sustainable technologies currently being developed.
Bull Moose Tube Co. (BMT), a Caparo Bull Moose subsidiary, announced plans to build a 350,000-ton-per-year pipe and tube mill on Steel Dynamics’ new Sinton, Texas, flat-rolled campus. The facility will produce sprinkler pipe and hollow structural sections (HSS) using steel from SDI’s plant. According to BMT, the mill will make product ranging in size from 4 to 14 inches square, 5 to 18 inches round, up to 80 feet long and thicknesses ranging from .187 to .750 inch. It will also expand BMT’s geographic footprint and allow the company to better serve customers in the Southwest, West Coast and Mexico markets. Company officials said they anticipate an early 2023 mill start-up.
Automation within forges and heat-treating facilities often consists of individually controlled processes for individual pieces of equipment, such as furnace heating or press operation cycles. Individual processes can be controlled at a Level I protocol. Full cell automation consolidates these automated steps and implements a central Level II control system, which is designed using a combination of Windows services and model-view-controller (MVC) architecture.
SECO/WARWICK will deliver two vacuum furnaces to Flansch-Tech, a specialist in aluminum and steel forging, in Budapest. According to SECO/WARWICK, one of the vacuum furnaces will be the largest in Hungary. The Vector with horizontal charge loading is equipped with a 15-bar nitrogen cooling gas-pressure system and a production work area of 900 mm wide x 900 mm high x 1,200 mm long). It will be used for the heat treatment of tool steels – mostly dedicated to hardening and tempering – and will allow Flansch-Tech to process larger parts.
Commercial Metals Company (CMC) announced that the Maricopa County Air Quality Department granted it an operating air permit, enabling the company to begin construction of its third technologically advanced micro-mill and the second at its Mesa, Ariz., site. According to CMC, the facility will be the first micro-mill in the world to produce merchant bar and rebar, and it will employ the latest in environmentally friendly steelmaking technology. The plant’s capability to directly connect to an on-site renewable-energy source, which CMC says is a first in North America, will further enhance the low emissions and efficient energy consumption of the micro-mill process.
Tenaris plans to restart activity at its two plants in Pennsylvania: the Koppel melt shop and Ambridge seamless pipe mill. The plant in Koppel – the company’s first domestic steel shop – is finalizing an investment announced in 2020 to upgrade its steel bar size capabilities while also incorporating additional improvements in safety and automation. Tenaris has since increased its investment to include the revamping of existing cranes used to feed the furnace with scrap metal and a new production management system to improve process control at the steel shop. The more than $15 million investment is projected to be completed in May with production to start up in June.
Ovako Steel’s 2018 investment in a vacuum tank degassing (VTD) facility is a critical development for the Smedjebacken mill. Removal of hydrogen by a state-of-the-art vacuum process now enables Ovako to address the needs of forgers that require high-performance, reliable and cost-effective steel for demanding applications such as those in the automotive industry.
Nucor Corp. will build a new tube mill on the site of its Nucor Steel Gallatin sheet mill in Kentucky. This location will allow the company to take advantage of investments made to expand capacity of the Gallatin mill and add a galvanizing line. The $164 million project is expected to be in operation by the middle of 2023 and create more than 70 new full-time jobs. The tube mill will have the capacity to produce approximately 250,000 tons annually of hollow structural section (HSS) steel tubing, mechanical steel tubing and galvanized solar torque tube. The Gallatin County site puts the facility near expanding solar markets in the United States and the largest consuming regions for HSS steel tubing.
Boston Metal raised $50 million in Series B funding, positioning the company to accelerate industrial-scale deployments of its molten oxide electrolysis (MOE) technology toward emissions-free steel. The company’s MOE technology uses electricity to transform metals from a raw oxide form into high-purity molten metal products, facilitating CO2 emissions-free steel production from a wide array of iron ores in a potentially more efficient, less costly and more sustainable approach.
