Salzgitter is investing a triple-digit million euro sum in a new walking beam furnace and waste gas heat utilisation system at the hot strip mill at its Salzgitter Flachstahl unit.
Tenova Italimpianti was assigned with the realisation of the project, Kallanish hears from the German steelmaker.
“With the new furnace, we will be reducing our energy requirements for slab heating in the hot flat steel area by up to 30%. This is another significant step towards reducing the CO2 footprint of flat steel products,” says Thomas Routschek, operations director at Salzgitter Flachstahl.
Hot combustion gases are generated when slab is heated in the walking beam furnace. The associated thermal energy is converted into steam in an exhaust gas heat recovery system. The DSD Power company was commissioned with the construction of the heat recovery system.
The new walking beam furnace will also enable the use of hydrogen, Salzgitter adds.
Thanks to its high energy efficiency, the project is being funded by German development bank KfW. The installation and commissioning of the new furnace is scheduled for 2028 completion.
