Ultrasonic additive manufacturing (UAM) combines a unique room-temperature metal deposition process with the ease of traditional CNC milling. A patented ultrasonic print head is integrated into three-axis mills to create a hybrid additive-subtractive process.
JSW Steel plans invest approximately $1 billion to ramp up the production capacity at its Vijayanagar plant in Karnataka, India, to 18 million metric tons per year from the current 12 million metric tons per year. A current expansion project, which will raise production at the plant from 12 to 13 million metric tons per year, includes the revamp and capacity upgrade of blast furnace-3 to improve hot metal availability. The company will also modify and enhance the capacity of its melt shop, its flat and long products mills and allied facilities to utilize the additional hot metal output. This project will be complete by March 2020.
SECO/WARWICK received an order from a U.S. manufacturer of flat-rolled aluminum sheet for a sow and T-bar preheat furnace system to achieve maximum product quality, energy savings and melt safety. The furnace offers optimum airflow management and a heating system that promotes efficient heat transfer throughout the work. It includes a patented movable baffle system and fixed base airflow spacers for maximum heat transfer to varying height loads. The system is PLC-controlled with remote I/O and dual operator-interface control stations.
Tenova LOI Thermprocess received an order from Fonderie Pandolfo for the delivery and installation of a twin-chamber melting furnace (TCF). This order will double the Italian company’s production rate. The TCF, with a capacity of 65,000 tons/year, is designed for aluminum scrap recycling. In order to cover a broad range of scrap, it combines pre-treatment and melting in one furnace.
High-temperature furnaces must withstand high temperatures that melt materials, such as titanium, without damage. Usually made of graphite, these furnaces frequently cause contamination with reactive carbon, which can cause damage to the manufactured products. Fully metallic furnaces and heating elements made of suitable materials, on the other hand, are a clean solution.
Kobe Steel Ltd. announced that its U.S. subsidiary, Kobelco Aluminum Products & Extrusions Inc. (KPEX) will invest approximately $42 million to increase the production capacity of its plant in Bowling Green, Ky. This investment, which is expected to create about 90 new jobs, will help meet the growing demand for automotive extrusions and fabricated products in the U.S. Plans call for new equipment to go into mass production in the first half of 2020. When the expansion is completed, KPEX will have two melting furnaces and two extrusion presses. Production capacity will increase to 1,000 tons per month, from the current 500 tons per month.
Commercial Metals Company (CMC) completed the acquisition of 33 rebar fabrication facilities and four steel mills in the U.S. (located in Knoxville, Tenn.; Jacksonville, Fla.; Sayreville, N.J.; and Rancho Cucamonga, Calif.) from Gerdau S.A. for $600 million. The mills have a combined annual mill rolling capacity of 2.5 million tons. CMC now has approximately 7.2 million tons of global melt capacity.
JSW Steel (USA) Inc. selected Tenova to supply melt-shop technology for its melt-and-manufacture contiguous plate and pipe facility in Baytown, Texas. The greenfield melting facility will include a Consteel Evolution EAF, two ladle metallurgy furnaces and a twin vacuum tank degasser for the production of high-quality steel slabs that will feed the new “plate mill of the future.”
