Some Factors Influencing Iron Ore Fired Pellet Quality

The .paper examines some variables which influence the quality of iron ore pellets, and which may be modified to meet the specific requirements of blast furnaces and direct reduction processes. Quality parameters defining pellet physical strength, size structure and reduction behavior considered important by the operators of blast furnaces and direct reduction processes are listed. Laboratory results are used to illustrate how feed preparation, and pellet chemistry car1 be altered to meet these specific quality criteria and some aspects of the economic impact of quality demands on the pelletizing operation are discussed.
