Stahl- und Walzwerk Marienhütte GmbH, with its production site in the heart of Graz, is Austria's only manufacturer of high-quality reinforcing steel. Just rebar made in Austria. Marienhütte produces more than 400,000 tons of reinforcing steel every year. Production is subject to external and in-house monitoring to ensure compliance with the quality standards of national standards in the construction sector. Marienhütte, where 300 employees produce almost continuously in a 4-shift system, has a long tradition in the production of high-quality reinforcing steel and mainly supplies bending shops and precast plants in Austria, Germany, the Czech Republic, Slovakia, Hungary, Slovenia and Croatia.
Marienhütte implements AI solution in steel production
Austrian steelmaker Stahl und Walzwerk Marienhuette Graz has successfully commissioned 'SST Temperature AI' software from Smart Steel Technologies.
The software in question is now integrated online as part of the production process, meaning that temperature control from the electric arc furnace (EAF) to the continuous caster is more precise than before, says SST.
According to SST, process stability is optimized across all stations, minimising temperature buffers and consequently lowering the EAF tapping temperature. The result, claims SST, is permanent energy andCO2 savings as well as increased process stability.
The commissioning of the software took just three months due to an intense collaboration between Marienhuette and SST.
