Powder injection times for hot metal desulfurisation have been dramatically cut by up to 50% at Corus Scunthorpe by the modernisation of the plant using Twinjection technology which introduces two powder streams into the hot metal down a single refractory lance. Lower sulphur levels can now be achieved using co-injection of lime and magnesium in a fraction of the previous injection times.
This allows Corus to increase the proportion of low sulphur steels that can be made through the plant and makes it possible, should the need arise, to cope with higher incoming hot metal sulphur level without reducing production rates.
