Reshape, boost and roll out
Technological advancement
In order to increase line productivity and eliminate the current limitations of the furnace when transitioning between different products, Fives proposed installing cutting-edge technology to ensure a more balanced flow across the production chain.
CELES EcoTransFlux™ - a transverse flux induction heater - is a very compact system designed for very rapid heating at extremely high temperatures, even for non-magnetic steel grades. This rapid heating technology added to the annealing section will speed up the process and allow for an additional output of more than 16% on certain products. Induction technology is also environmentally friendly, as it significantly reduces NOx and CO2 emissions.
"Arvedi AST has chosen Fives as its technology partner for the project, relying on the company’s undisputed leadership in transverse flux induction heating technology and integrated digital solutions. We firmly believe that the electrification of processes and the implementation of advanced digital solutions, including sophisticated artificial intelligence algorithms, are an integral part of our decarbonization plan for the strategic development of the site," says Gian Luca Gigli, CTO at Arvedi AST.
Significant improvements will also be achieved thanks to a digital solution to control the heating section.
Virtuo™-L, a thermal process solution will be installed to decrease fuel consumption and improve mechanical properties through precise transition management. It’s an industry-proven solution based on predictive modelling that implements a precise control of the furnace to automatically adjust the heating power and improve the temperature transitions of the strip regardless of operator’s shift. The direct benefits are a reduction in coil rejections by more than 5% and better heating management resulting in lower gas consumption.
In addition, an AI-based cooling model will be introduced to regulate the cooling speed of the strip.
“We are proud to collaborate with Arvedi AST in advancing intelligent manufacturing systems and sustainable process innovations that redefine the future of stainless steel production in the plant,” says Steve Decroix, Vice President of Steel Services and Digital Sales at Fives.
Industrial benefits
The introduction of transversal induction technology and digital furnace control will not only increase the plant’s productivity, but also pave the way for long-term operational resilience. Arvedi AST has already benefited from another digital solution from Fives. Eyeron®, an intelligent quality management system, was installed across the entire integrated plant to take quality management to a higher level.
