Jubilee weekend for Europe's biggest blast furnace

This weekend, Schwelgern blast furnace No. 2 in Duisburg/Germany is going to produce its 70 millionth t of hot metal. This record will be obtained within the first furnace campaign which started in autumn 1993.

Europe´s biggest blast furnace with a hearth diameter of 14.9 m has been supplying the two BOF melt shops Bruckhausen and Beeckerwerth for 19 years with an average hot metal amount of around 12000 t/d.

Featuring 42 tuyères and 4 tapholes BF 2 has been processing almost 19000 t of iron ore and up to 4000 t of coke. It has also been delivering high-value by-products, such as, around 3300 t of blast furnace slag/day as a basis for cement manufacture, and around 12 million m³ top gas per day for use in the mill's energy network.

"Blast furnace 2 has an extremely sophisticated design in terms of its refractory lining and furnace cooling system, and it's still state-of-the-art today," Wolfgang Wiese, head of the Schwelgern blast furnace plant, told STEEL GRIPS online. "The first reline is scheduled for summer next year, and the preparations are already in full swing."
