In order to be able to meet the demand for rolled products with a reduced CO2 footprint now, work is currently underway at Salzgitter Flachstahl to reduce CO2 emissions in steel production using the resources already available in the group. The steel production process using the electric arc furnace used at Peiner Träger GmbH in Peine has the advantage over the classic blast furnace route that the input material used for slab production consists of 100% scrap. In close teamwork between Peiner Träger and Salzgitter Flachstahl, a concept was developed in the second half of 2020 to supply SZFG with Peiner slabs made of electrical steel in order to be able to produce flat steel with a significantly reduced CO 2 footprint. After the casting equipment for slab production had been upgraded, the first slabs were delivered to Salzgitter as early as November 2020.
In order to enter environmentally friendly, low CO2 steel production based on Peiner slabs, a selection of grades was developed between Peiner Träger and Salzgitter Flachstahl, with which a selected segment of flat steel production can already be served. Due to the metallurgical focus of PTG's electric steelworks on long steel products, it is currently not possible to fully implement the Salzgitter Flachstahl product range. Both soft and some micro-alloyed steels are currently produced from Peiner slabs. As part of the process and product launch, newly produced PTG grades are inspected after each production step in Salzgitter and only passed on to the next process step after they have been approved.
The first low CO2 products are already being processed by the customer, and the knowledge gained so far will be used to gradually expand the range of qualities of the low CO2 production route presented here
