L&L Special Furnace Co. shipped a front-loading box furnace to an aerospace manufacturer located in the southeastern United States. The state-of-the-art-facility will be opening soon, and it will be a central part of a heat-treating center for aerospace and military components. The highly uniform furnace has working dimensions of 60 inches wide x 60 inches high x 60 inches deep. There are a series of castable piers and an alloy grid that supply a very stable work platform for various part sizes and configurations.
Tenova LOI Thermprocess received an order from Belgium’s E-MAX group that includes engineering, supply, erection and commissioning of a twin-chamber melting furnace and a melting and casting furnace for the production upgrade and modernization of the E-MAX Kerkrade plant. Commissioning is scheduled for the beginning of 2022. E-MAX delivers sustainable, high-quality aluminum profiles to various sectors of the aluminum market. The Dutch branch in Kerkrade is the central operation plant in the E-MAX group for the production of extrusion billets.
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.
Andritz received an order from Thyssenkrupp rothe erde (Xuzhou) Ring Mill Co. Ltd. to supply eight chamber forging furnaces for its plant in Xuzhou, China. Thyssenkrupp rothe erde manufactures slewing bearings and seamless rolled rings used in applications ranging from industrial machinery, automotive engineering and aerospace facilities to wind turbines and tunnel-boring machines. Andritz’s scope of supply includes engineering, manufacturing, electrical equipment and automation software. The furnaces will include low-NOx burners that will minimize emissions and fuel consumption. Start-up is scheduled for the first quarter of 2022.
Solar Manufacturing shipped an external-quench vacuum furnace to a West Coast aerospace manufacturer. The furnace has an all-metal hot zone, load capacity up to 10,000 pounds and a maximum operating temperature of 2400°F. It also includes a 2-bar quench system optimized for argon with a 150-HP quench motor and variable-frequency drive. The AMS 2750F-compliant furnace, which has a work zone measuring 48 inches wide x 48 inches high x 72 inches deep, will be primarily used for vacuum heat treating investment castings.
Nucor Steel Florida safely started on schedule in December 2020 by melting, casting and rolling in endless mode from the first heat. Located in Frostproof, Fla., the minimill has a rated capacity of 380,000 shtpy and will produce rebar ranging from 0.37-1.4 inches (9.5-35.8 mm) in straight bars up to 60 feet and spooled coils up to 5 tons. Danieli’s MIDA casting and rolling technologies significantly reduce the overall CO2 emissions due to the absence of a reheating furnace. Nucor Steel Florida will allow the company to satisfy the regional demand of steel rebar and recycle the scrap available in the area.
ArcelorMittal and Nippon Steel Corp. executed a definitive agreement to invest approximately $775 million to build an electric-arc furnace (EAF) at AM/NS Calvert, a joint venture between the companies located in Calvert, Ala. The EAF is scheduled to start operation in the first half of 2023. AM/NS Calvert currently produces steel-sheet products by processing semi-finished products (slabs) procured from domestic and overseas suppliers. The new EAF will enable the facility to manufacture the slabs necessary to produce its steel-sheet products. This, in turn, will enable AM/NS Calvert to shorten lead time in slab procurement, improve its productivity through utilization of self-manufactured high-temperature slabs and increase the domestic procurement ratio of slabs. The EAF will have a capacity of 1.5 million metric tons per year.
AVS Inc. (AVS), a manufacturer of custom vacuum and pressure furnaces, announced the successful transfer of ownership from Steven Levesque to Jacob (Jake) Krashan. Since 1984, Levesque had committed his life’s work to the design, development and construction of quality vacuum and pressure furnaces. In 2005, he became CEO, president and owner. Levesque now confidently leaves Ayer, Mass.-based AVS in the capable hands of Krashan, a long-term employee who was promoted to COO in 2015. He became CEO, president and owner on Nov. 20, 2020.
The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) awarded nearly $4 million in grants to help accelerate the adoption of new measurement methods and standards to advance U.S. competitiveness in metals-based additive manufacturing (AM). According to NIST, these projects will improve U.S. manufacturers’ ability to use metals-based additive manufacturing to make high-quality, innovative and complex products at high volume. Through its own research and with these grants, NIST is addressing barriers to adoption of additive manufacturing, including surface finish and quality issues, dimensional accuracy, fabrication speed, material properties and computational requirements.
