Last of three LD (BOF) converters from Primetals Technologies starts up at SSAB in Finland

Print

In September, the last of three LD (BOF) converters supplied by Primetals Technologies commenced

operation at the Raahe, Finland works of SSAB Europe Oy. The first converter was started up in October

2015, the second one in May 2016. With almost unchanged space requirements, the new converters

have a larger reaction volume. The maintenance-free Vaicon Link 2.0, which will be used as the

converter suspension, minimizes stress caused by heat-induced deformation and has a longer useful life.

A blowing lance tip geometry adjusted to the new converter geometry, bottom stirring and a slag stopper

improve the metallurgical properties of the steel produced. A new refractory concept will ensure long

converter lining campaign.
