Abstract To make reasonable use of converter sludge and reduce the concentration of harmful elements in iron making process,the utilization of converter sludge by rotary hearth furnace was studied. Converter sludge had little effect on the quality of green balls,but it could increase the strength of dry balls,which could reduce the cracking and pulverization of pellets during transport and preheating process. The basicity and carbon content of raw materials were the key factors affecting the quality of metallized pellets,which were significantly affected by converter sludge. However the metallization rate and strength can be guaranteed by control the basicity between 0.75-0.85 and the mass percent of carbon between 11%-12%. The proportion of converter sludge was gradually increased from 8% to 24% during the industrial testing. The basicity and carbon content were adjusted by controlling the ratio of each raw material,and metallized pellets could meet the needs.

Key words： converter sludge rotary hearth furnace metallized pellet basicity carbon mass percent
