Abstract

Pelletizing of iron ore fines is an important process used to produce high quality of raw materials for the subsequent reduction processes in the ironmaking industries. The process involves the production of green pellets and subsequent induration on a traveling grate furnace to promote inner partial melt and agglomeration which confer physical and metallurgical proprieties appropriated to the subsequent reduction processes. The pellets are produced with addition of charcoal to improve efficiency in the reduction processes. The lignin coal from sugarcane straw is an alternative source to replace the charcoal or coke in the self reduction of pellets. This work focused on the influence of biomass on the chemical kinetics parameters inner agglomerate pellet structure under industrial process conditions of the travelling grate furnace due hot gas flows within the pellets.
