SUMMARY:New MgO and Al203 slag-making process management at Celsa UK toward a more sustainable and efficient EAF steelmaking process: Calculations and industrial results
DESCRIPTION:Celsa group and Celsa UK are a recognized leader in scrap recycling and in sustainability. The scrap recycling paves the way to EAF slag-making process challenges due to scrap quality volatility in general and to Al2O3 slag content management in particular. 
Together Celsa UK and Lhoist implemented  a cost-efficient slag making process managing the inconvenience of High  and variable Al2O3 content of the EAF slag. The key lever was introducing  dolime as a MgO source input to control and regulate the slag viscosity. Based on theoretical approach and calculations,  a Al2O3 and MgO management  of the EAF slag-making process was defined. This process was implemented and tested industrially at Celsa UK  bringing positive impacts on material recovery, refractory wear, energy yield, CO2 emission intensity in particular.
This paper will describe the theoretical approach and calculations as well as will present and discuss the industrial results of the new EAF slag-making management at Celsa UK leading to a more sustainable and cost efficient EAF process.
