SUMMARY:Development of technology to use industrial wastes in EAF
DESCRIPTION: In these day, Carbon Neutrality is important issue in the world. And iron&steelmaking industry is also undergoing process change to achieve carbon neutrality. The biggest change is process transitions from BF-BOF to DRI-EAF. In case of BF-BOF process, They can produce from normal grade of steel to AHSS grade steel. But this process need to generate a plenty of CO2 emission, 1.85tCO2/steel ton.[1,2]. On the other hands, DRI-EAF process is also possible to produce from normal to AHSS, But this process CO2 emission is just half of BF-BOF, 0.97tCO2/steel ton. In other words, producing steel using an EAF is more effective in terms of CO2 emission compared to BF-BOF process. And by using DRI in EAF, They are able to produce high grade steel. 
 EAF technology is developing from 1968 to 2010 in the direction of saving EAF energy consumption. The use of industrial wastes in EAF technology is important part in terms of diversifying raw materials for EAF in the future, and this technology can meet another jump up in saving EAF energy consumption. And using industrial wastes also decrease CO2 emission. In this study, I share some case of using industrial wastes in EAF especially Al dross. In case of Al dross, we put the Al dross in EAF with Fe powder and Na2CO3. Fe powder aim to increase density of Al dross product and Na2CO3 is for stabilizing P2O5 activity coefficient in slag. In this paper, we share our experience of using industrial waste in EAF and we also share our future works related to use wastes.
