Developing and testing new steel alloys will be up to 100 times faster in the Industry 4.0 (US)

Chemical analysis of steel – Dr James McGettrick of Swansea University, with an X-ray Photoelectron Spectrometer. This analyses the extra nanolayers which are added on top of steel, for example to improve adhesion or resistance to corrosion.

Developing and testing new steel alloys will be up to 100 times faster, allowing new products to reach market more quickly, thanks to £7 million of funding announced for a ‘virtual factory’ being developed by Swansea University, in partnership with Tata Steel and WMG, at the University of Warwick. Steel is the most widely used structural material in the world.It is at the heart of major manufacturing sectors such as the car industry, construction, packaging and defence. It is indispensable for national infrastructure such as transport, communications and energy, and for high-tech uses in energy-positive buildings to wind turbines and electric vehicles. “This project is a huge boost for innovation as it massively speeds up the development of new alloys.It means steel producers can deliver new and betterContinue reading

POSCO, Korea’s largest steelmaker, has valued the importance of talented people for the past five decades since its founding in 1968. Its management philosophy is devoted to nurturing talented individuals. To enhance job competency of its employees, POSCO has operated a training institute since 1969 while the group was busy constructing its steel mill. To strengthen its competitiveness, POSCO recently announced it will spend 45 billion won ($40.45 billion) over the next five years and hire an additional 20,000 employees by 2023. POSCO said creating 20,000 jobs is a 190 percent increase compared to the steel maker’s recruiting performance of the past five years, in which it hired about 7,000 employees. “As POSCO has valued the importance of talented individuals since its founding, the recruitment plan is to secure a growth engine for the group in the era of the Fourth Industrial Revolution,” the steelmaker said. POSCO said hiring moreContinue reading

ArcelorMittal vend ses aciers en ligne (FR)

Lancée en janvier 2018, la plateforme E-Steel permet au géant de la métallurgie de vendre 20 % de ses produits en France online.

Au départ, seule l’agence ArcelorMittal de Colomiers, qui a lancé le concept en 2017, et sept autres agences en France (Caen, Langon, La Roche-sur-Yon, Reims, Rennes, Rouen et Savigny-le-Temple) avaient mis leurs stocks à disposition des clients via un site d’e-commerce. Tubes carrés en inox, poutrelles en acier, barres plates en aluminium, tôles, plaques : l’éventail des produits était large. Six mois après son lancement, ArcelorMittal vient de tirer un premier bilan de cette nouvelle façon de vendre de l’acier. Et il est positif, selon le Continue reading

NASA Welding Technologies Could Revolutionize Workboat Fabrication (US)

Solid-State Welding Processes Being Developed for NASA Manufacturing Programs Could Significantly Reduce Workboat Fabrication Costs

Whether it is for a tug boat, cargo vessel, or an offshore supply ship, much of the workboat fabrication industry is located along the Southern Coast of the U.S. But a visit to any one of the workboat facilities in that area (or any other in the country) would reveal antiquated and archaic fabrication processes used seventy years ago. The workboat manufacturing process is very expensive, labor intensive, and has not really changed since World War II. Perhaps it is time to go back to the drawing board and redesign the workboat manufacturing process from the ground up so that new solid-state welding processes and other aerospace technologies being developed at NASA’s Marshall Space Continue reading

Steel Giants Dofasco and Algoma Bet on Artificial Intelligence to Disrupt The Steelmaking Industry (US)

A full ladle of liquid steel, seen here at the ArcelorMittal Dofasco plant in Hamilton, weighs about 318 tonnes, and can be heated to about 1,600 C. Dofasco wants to fully automate its ladle metallurgy process – the stage when trained operators manually add the ‘secret sauce’ to liquid steel before it is cast into numerous grades of steel slabs for construction, car-making and packaged goods. Instead, digital sensors could consistently determine the precise temperature at which to add the right ingredients to produce the desired grade of steel

Dofasco wants to improve its ladle metallurgy process, a key step in steel-making, while Algoma eyes the potential to automate product development. In both cases, the companies look to artificial intelligence and machine learning to help them set new, world-beating standards of efficiency, quality, energy savings and generate as-yet unimagined innovations.

Steel-making is a science but still relies on experienced human operators at key stages of production. But what if “smart” technology replaced manual tasks with digital sensors that consistently update information and reveal insights impossible to detect with the trained eye – or brain ?  Answering the “what if” question is a top priority for Canadian steel giant ArcelorMittal Dofasco as it strives to compete globally. To speed the hunt for answers – when Canadian steel already is under siege from U.S. tariffs in a burgeoning global trade war – the Hamilton-based manufacturer hopes to join forces with innovative startups, university researchers and even a competitor, Essar Steel Algoma Inc., to promote a new generation of manufacturing.

“Traditionally, the research and development of a product in steel-making is a slow process, In future,  Algoma could apply self-learning algorithmic models to assess multiple variables at once – beyond the capacity of any experienced technician. As a result, the product development cycle could take just 15 days to two or three months.”

Pramod Shukla, chief operating officer of Algoma, in Sault Ste Marie, Ont

In future, he says, Algoma could apply self-learning algorithmic models to assess multiple variables at once – beyondContinue reading
