While significant results have been achieved through high-quality lime and dolime dosing in BOF, Carmeuse and strategic partners are always looking to further develop this technology for optimum performance.
Carmeuse has developed value in use models to simulate the real effect of lime quality on process efficiency on the steelmaking process. These simulations show how important lime quality is and the significant effect it has on the steel process efficiency including cost, energy efficiency and steel process CO2 emissions. It has been demonstrated that lime quality has a significant impact on the scope 1 CO2 emissions of the steelmaking process.
Lime injection in the BOF converter has been studied through partnerships with world leading injection technology companies to develop and successfully employ lime injection through modified oxygen top blowing lances.
