  • Strong signal sent to customers and partners
  • Defined step within the context of SALCOS® - Salzgitter Low CO2 Steelmaking

With the relining of Blast Furnace A now commencing, the Salzgitter Group is taking a key operational step towards securing its hot metal base within the context of the incremental transformation phase towards low-CO2 steel production by 2033.
In the course of a construction phase lasting around 100 days, Blast Furnace A will be completely overhauled - relined, as it is referred to in the steel industry. Among other things, the refractory lining will be renewed and the complex process and control technology modernized. The tapping of the "furnace sow" marked an important initial step, in which the remaining pig iron was drained from the blast furnace hearth.
Just over 100 million euros will be invested in this complex construction project which is involving the company Pirson Montage AG as an essential partner.
The supply of primary materials to internal processing plants and sister companies during the construction phase has been guaranteed thanks to the pre-production of slabs.
As Ulrich Grethe, Chairman of the Management Board of Salzgitter Flachstahl GmbH, explained the relining: "This investment sends out a strong signal that we will continue to be a reliable partner for our customers in the transformation phase that will extend up to 2033. In pursuing SALCOS® - Salzgitter Low CO2 Steelmaking, we are pioneering industrial transformation. The defined approach involving investment in the existing operations and the simultaneous construction of the new process route is a unique selling point in the steel industry."
Gerd Baresch, Managing Director Technology Salzgitter Flachstahl GmbH, commented as follows: "We are gradually abandoning the blast furnace route and have already started to install the process route for new aggregates such as the direct reduction plants and the electric arc furnaces. Accordingly, we will be decommissioning one of our blast furnaces as early as 2026. By pursuing this approach within the framework of SALCOS® , we are ensuring that the Salzgitter steel location and its jobs will be fit for the future."

Blast furnace A went was commissioned in 1977 and has been relined several times. The blast furnace has an annual capacity of around 2 million tons of pig iron.
