Development of Agglomeration Process to Utilize the Ferromanganese Fines in Steel Making Process

摘要

An agglomeration process is developed to utilize FeMn fines of 98%, respectively. Compressive strength was 55 MPa and density was 5200 kg/m~(3). Usability of FeMn briquettes along with the FeMn lumps was evaluated in lab as well as in the plant. The results of lab test revealed tha FeMn briquettes dissolved faster than lumps. Improvement in Mn recovery was also observed in case of FeMn briquettes. Preliminary cost analysis indicated significant saving in alloying cost in steel making by use of briquettes made of low cost fines.
