Commercial Metals Company opened a 63,000-square-foot addition to its facility in Mesa, Ariz. The expansion will allow the company to produce hot-rolled, spooled steel rebar from mostly recycled scrap metal. The electric-arc furnace (EAF) micro-mill, which opened in 2009, uses a continuous technology and is the first of its type to be successfully operated in the U.S., according to CMC. More than 450,000 tons of scrap metal are recycled each year into steel bar products at CMC Steel Arizona for use in construction and fabrication. The facility produces straight and spooled rebar in a range of sizes and lengths.
The Timken Company acquired Diamond Chain Company, a supplier of high-performance roller chains for industrial markets, from Amsted Industries. Indianapolis, Ind.-based Diamond Chain has manufacturing operations in the U.S. and China and employs approximately 370 people. The company uses enhanced heat-treatment processes that help pins maintain rigidity in the most challenging environments. Diamond Chain also utilizes laser fabrication to drastically cut manufacturing times for custom-made chain attachments.
Epiroc, a productivity provider for the mining and infrastructure industries, held a groundbreaking ceremony for a new heat-treatment plant for rock drills in Örebro, Sweden. The 1,400-square-meter facility, which will be able to run 24 hours a day due to automation, is expected to be up and running by late 2020. The plant was designed for energy efficiency. For example, residual heat will be recycled internally to heat buildings.
The ExOne Company announced a material collaboration with Sandvik Additive Manufacturing, a division in the global engineering Sandvik Group. The material collaboration will focus on qualifying and optimizing Sandvik’s Osprey metal powders with ExOne’s binder-jetting machines. It will include studying powder and binder interactions; developing 3D machine process settings; and creating post-processing heat treatments for various materials, including stainless steels, tool steels and nickel alloys.
Dr. Valery Rudnev presented the 77th Woodside Lecture May 13 in Livonia, Mich. His presentation focused on recent theoretical and practical novelties in induction heat treatment. Common mispostulations associated with induction heating and frequently overlooked metallurgical subtleties were also discussed.
Family-owned heat-treatment company GalvanoTechnik of Lombardy, Italy, expanded its portfolio to include Nitreg-controlled nitriding, Nitreg-C nitrocarburizing and ONC in-process oxidation treatments. The company invested in a compact Nitrex system configured to process 23.5-inch-diameter x 35.5-inch-high workloads that weigh up to 1,300 pounds. The system complies with the temperature-uniformity requirements of AMS 2750E and meets the specifications of ASM 2759/10, which make it possible to consistently achieve the required metallurgical and mechanical properties for controlled nitriding.
SECO/WARWICK Group’s subsidiary based in Meadville, Pa., has been awarded a major contract to build and commission a specialized aluminum solution heat-treating furnace for a U.S. manufacturer. The furnace, which is AMS 2750-compliant and Nadcap-capable, will be engineered to load, heat treat, quench and discharge with minimal operator assistance. It will be used to heat treat products for automotive, aerospace and medical applications.
HP and Siemens expanded their strategic alliance to help customers transform their businesses with industrial additive manufacturing (AM). Siemens and HP will incorporate systems and software innovations including overall product lifecycle management (PLM), AM factory optimization, industrial 3D printing and data intelligence, manufacturing execution and performance analytics.
Nucor Corp. announced a capital investment that will add vacuum degassing to its engineered bar capabilities at its mill in Darlington, S.C. Adding this capability will enable the mill to produce engineered bar products meeting some of the most stringent quality specifications in the industry. The vacuum degassing system is expected to begin operations in late 2020. According to Nucor, the investment wlll position it to better serve customers in the southeastern U.S.
The Aluminum Association released “The Aluminum Agenda: A Policy Roadmap for a Competitive U.S. Aluminum Industry,” which lays out principles and policy goals for a sustainable U.S. aluminum sector in the 21st century. The document was developed in consultation with aluminum companies spanning the entire industry value chain.
