Nucor Corp. selected SMS group for the supply of a single-strand continuous caster for ultra-wide and thick slabs. Designed for an annual capacity of 1.45 million tons, it will be a core element of the production chain of Nucor’s new plate mill in Brandenburg, Ky. The companies say the casting machine will be one of the largest of its kind worldwide. The caster will produce slabs 8-12 inches (200-305 mm) thick up to 124 inches (3,150 mm) wide. Slab lengths will vary from 104 to 600 inches (2,642 to 15,240 mm).
Andritz received an order from Steel Dynamics Inc. for the supply of key process equipment for the existing continuous galvanizing line (CGL) at its Columbus, Miss., plant. The scope of supply includes engineering and delivery of a new direct-fired furnace, differential rapid jet cooling and after pot coolers. The project will be implemented during the fourth quarter of 2020. Andritz will also supply the model-predictive advanced furnace control for the complete furnace sections as well as the automation and electrical equipment.
L&L Special Furnace Co. Inc. shipped a floor-standing box furnace to a high-tech aerospace and associated components manufacturer located in the southeastern U.S. The furnace, which has a work zone measuring 120 inches wide x 48 inches high x 72 inches deep, will be used for processing aerospace parts and various thermal applications. It has a temperature gradient of ±20°F from 1100-2150°F using eight zones of temperature control with biasing to balance any differential in temperature gradients.
GE Additive entered into a five-year cooperative research and development agreement (CRADA) with the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL). The agreement focuses on processes, materials and software to drive industrialization and encourage the broader adoption of additive-manufacturing (AM) technology. The agreement supersedes an existing CRADA in place since 2012 between ORNL and GE Additive Arcam EBM. ORNL purchased its first Arcam EBM system in 2009. Since that time, ORNL and the Arcam EBM teams have worked together to create opportunities for companies in multiple U.S. manufacturing sectors to adopt electron-beam melting (EBM) technology.
Alfa Romeo Racing, operated by Sauber Motorsport AG, selected Quintus Technologies as its hot isostatic pressing (HIP) partner. The Formula One team invested in a press with proprietary URQ technology, which allows heat treatment and cooling to be combined in a single process, known as high-pressure heat treatment (HPHT). HPHT and HIP are used for the consolidation and densification of metal, producing a maximum theoretical density, ductility and fatigue resistance in high-performance materials. This makes it ideal for ultrahigh-performance automotive applications.
Danieli has been selected to supply equipment for Nucor’s new greenfield plate steel mill in Brandenburg, Ky. Danieli will supply an electric-arc furnace (EAF) melt shop and plate/steckel mill, as well as an electrical and automation package provided by Danieli Automation. The EAF will be equipped with all modern mechatronic devices to improve its performance and safety. Danieli will also supply secondary metallurgy equipment, including a twin-station LMF and a twin-station VTD equipped with mechanical pumps. Both units will include with the latest automation and process models to ensure precise chemistry and temperature control.
The ExOne Company and Global Tungsten & Powders Corp. (GTP) entered into a collaboration to advance tungsten-based metal 3D printing using binder jetting. Binder jetting is a 3D-printing process that uses a digital file to inkjet a bonding agent into a bed of powder particles, creating a solid part one layer at a time. The new ExOne-GTP collaboration focuses on the development of two metal matrix composites: cemented carbide (WC-Co), a material with very high hardness and toughness that is widely used for the production of cutting tools and wear-resistant parts; and copper-tungsten (CuW), which is used in applications where high heat resistance, high electrical and thermal conductivity, and low thermal expansion are needed.
Markforged opened a 25,000-square-foot manufacturing facility in Billerica, Mass, that will enable the company to more than double its production capacity, support increased demand for its metal and carbon-fiber 3D printers and create new jobs. The new facility will support the fabrication of all Markforged materials that are used by companies in the aerospace, automotive and manufacturing fields. It currently hosts 35 members of staff. Markforged expects to add another 25 hires in the coming years.
Danieli Olivotto Ferrè started up a tube roller-hearth annealing furnace at Tenaris Tamsa in Veracruz, Mexico. The furnace is designed to treat steel tubes coming from cold or hot processing with a maximum throughput of 5 tons/hour. It is able to perform different heat-treatment cycles, including normalizing, annealing, tempering and stress relieving. The pipe to be treated has an OD range from 15-120 mm, thickness from 1.5-20 mm and length up to 16 meters (52.5 feet).
Delta H supplied a dual-chamber aerospace heat-treating (DCAHT) system to Sintavia, a Hollywood, Fla-based provider of additive-manufacturing services. The furnace features dual chambers operable to 1200°F and 500°F with precision control and temperature uniformity and a roll-away stainless steel quench tank. The DCAHT system qualifies as Class 2 (+/-10°F) per AMS 2750E and includes all controls, data-acquisition technology and spare-parts package to be in full compliance with all aerospace pyrometry standards, including Nadcap.
