Salzgitter restarts blast furnace after final revamp

Salzgitter says its blast furnace A has been fired up again following a complete modernisation that lasted over 100 days, Kallanishlearns from the German steelmaker.

With the relining, Salzgitter has taken a key step towards securing its pig iron supply within the context of the incremental transformation phase towards low-CO2 steel production by 2033, it adds.

The furnace’s complete overhaul included the renewal of the refractory lining with 3,000 tonnes of carbon bricks and other refractory materials, and a modernisation of the complex process and control technology. Over €100 million ($109m) was invested in the measure, with Pirson Montage AG involved as an essential engineering partner.

Blast furnace A was originally commissioned in 1977 and has been relined several times. The unit has an annual capacity of around 2 million tonnes of pig iron. Salzgitter stated earlier that this will be the last reline of a blast furnace as the company is converting to direct reduced iron (DRI) technology.
