| Abstract Scope |
Steel produced from an electric arc furnace is refined in the secondary steelmaking process such as the ladle metallurgical furnace, to remove harmful impurities such as sulfur. Slag optimization is fundamental to steelmaking, as poor slag practices reduce steel quality and refractory life, increasing production downtime and costs. There could be a trade-off between the slag desulfurization capacity and slag chemical neutrality in relation to the refractory lining. This work aims to optimize a ladle furnace slag to protect refractory lining and simultaneously maintain the slag’s desulfurization capacity, taking into account stringent steel quality requirements. A systematic thermodynamic evaluation is carried out to optimize slag basicity and viscosity as a function of process parameters in a dynamic industrial context, the details of which are discussed in the present work. |
