Seco Warwick CAB furnace enables auto parts maker to cut costs, control brazing quality
Source:
Seco Warwick, Meadville, Pa., has delivered and commissioned the first-ever vacuum purging semi-continuous Active Only CAB furnace for a North American automotive aftermarket manufacturer. It is the company’s first furnace of any type, and simultaneously its largest capital equipment investment to date.
The new semi-continuous Active Only CAB furnace, equipped with vacuum purging in the loading and unloading chamber, is one of its kind in the industry. It allows for the reduction of nitrogen consumption and cost, and it provides extraordinary control of brazing atmosphere quality. This applies in particular to heat exchangers with joints brazed in a closed space. Vacuum purging allows for the perfect removal of oxygen from these spaces before brazing, which cannot be achieved by traditional purging.
Many business owners are starting to figure out that not all services should be outsourced. One such industry group is automotive aftermarket manufacturers, who, with Seco Warwick technology, gain an opportunity to rein in their costs by saving money on outsourcing, as well as reduction of nitrogen expenses. The new furnace allows customers to braze their own heat exchangers, control their own quality, and manage their production schedules more reliably to improve deliveries to their customers.

Nucor to invest $1.35 billion for new mill producing 1.2 million tons of steel plate per year
Source:
Nucor Corp., Charlotte, N.C., announces that it will build its new state of the art steel plate mill in Brandenburg, Kentucky, located along the Ohio River southwest of Louisville. The company will invest approximately $1.35 billion to build the mill, which will be capable of producing 1.2 million tons per year of steel plate products. The plate mill will employ more than 400 full-time teammates at an average annual salary of $72,000, and is expected to be fully operational in 2022, pending permit and regulatory approvals.
"This strategic investment will enable us to build a clear market leadership position in the U.S. plate market. Kentucky is an excellent location for this mill, right in the center of America's largest plate consuming region," says John Ferriola, Chairman, CEO & President of Nucor Corporation. "Our acquisition of the Gallatin sheet mill in Ghent, Kentucky, five years ago has been a tremendous success, and we are pleased to add a second mill in the state."
The new plate mill will significantly strengthen Nucor's plate product portfolio, giving the company the ability to produce 97 percent of the products demanded in the domestic plate market, including the specialty higher-margin products. The mill will produce cut-to-length, coiled, heat-treated, and discrete plate ranging from 60 to 160 inches wide, and in gauges from 3/16 of an inch to 14 inches. The selected location on the Ohio River will give Nucor logistical advantages in sourcing raw materials and serving customers throughout the Midwest. Nucor currently operates plate mills in North Carolina, Alabama, and Texas.
Nucor has two additional major investment projects underway at its Gallatin sheet mill in Kentucky. Nucor Steel Gallatin's new galvanizing line will be operational during the second quarter of this year. And, its project to increase Gallatin's hot rolled coil capacity at expanded widths of up to 73 inches is expected to come online during 2021. The new plate mill and the projects at Nucor Steel Gallatin represent more than $2 billion in investments in the state of Kentucky.

Russian scientists research steel-vanadium-steel laminate for next-gen nuclear reactors
March 24, 2019
Source:
Materials scientists from the Russian National University of Science and Technology (NUST MISIS) announce that they have developed a unique steel-vanadium-steel sandwich material that is able to withstand temperatures of up to 700°C, hard radiation exposure, mechanical stress, and chemical exposure for a long period of time. The material was designed to be used in the shells of nuclear reactor cores.
“The ferritic steel provides corrosion resistance, and the vanadium alloy (V-4Ti-4Cr) provides heat resistance and radiation resistance sufficient to withstand the effects of the ultra-rigid environments of a nuclear reactor," says Aleksandra Baranova, research co-author, post-graduate student of NUST MISIS Department of Metallurgical Science and Physics of Strength.
The maximum operating temperatures of the fuel element shells in the new generation reactors reach 550 to 700°C. Sodium, the liquid metal coolant, acts outside. The loads created are much higher than those that the core shells of existing reactors can withstand.
To close the nuclear fuel cycle in a new generation fast neutron reactor, new structural materials that can provide a higher fuel burn-out are needed. These materials should withstand damaging radiation doses of up to 180-200 dpa (displacements per atom), instead of the maximum 100-130 dpa, that are typical for existing materials.
The researchers say that fabrication problems were solved by the use of complex deformation processes and heat treatment of three-layer billets. The process includes hot co-extrusion (pressing), radial forging, and joint rolling. As a result, a "transition zone" is formed at the boundary of the components, and the alloys diffuse into one another, which provides a high-strength bond.
The research team has reportedly managed to create a prototype of the core shell, which is a monolithic three-layer tube. Laboratory tests are said to show high mechanical strength of the composite at operating temperatures of up to 700°C. In the near future, the team plans to begin long-term studies for radiation resistance.

GE Aviation’s Catalyst turboprop engine wins award for 3D-printed design
Source:
GE Aviation, Auburn, Alabama, announces that it has been recognized by Aviation Week with a Laureate Award in the Business Aviation category for the GE Catalyst program’s innovative work with additive manufacturing design and implementation.
GE’s Catalyst is the first clean-sheet turboprop engine for the Business and General Aviation market in more than 30 years. It includes more printed components than any production engine in aviation history. More than 800 conventionally manufactured parts have been reduced to 12 additive parts on the engine.
The GE Catalyst engine was chosen by Textron to power the new Cessna Denali and is currently going through certification testing. GE’s work on its newest turboprop has been a worldwide collaboration. It includes 22 GE Aviation facilities in Europe with teams located in the Czech Republic, Poland, Germany, and Italy, as well as 1800 engineers.
“For more than six decades, Aviation Week editors have annually awarded Laureates to great achievers in aerospace and aviation,†said Aviation Week Network Editorial Director Joe Anselmo. “GE Aviation and this year’s winners exemplify the spirit and innovations that are transforming our industry to meet the challenges of tomorrow.â€
Additive components reduce the Catalyst’s weight by five percent while contributing a one percent improvement in specific fuel consumption. Thanks to additive manufacturing, the Catalyst program has benefited with a reduction of cycle time, as well as fewer first article inspections, less inventory, fewer defect opportunities, and a reduction in tooling costs.
In addition, GE Aviation is said to be planning a $50 million expansion to its Auburn additive manufacturing capabilities. Increased capacity will allow the high-volume production of a new jet engine component, the 3D-printed bracket for the GEnx-2B engine program. GE has already invested more than $100 million in its Auburn operation, which began producing the additively manufactured fuel nozzle tip for the LEAP jet engine in 2015. As of October 2018, some 30,000 of these parts had been produced.
