PROCESS OF CONTROLLING THE FE++ CONTENT OF SINTERED IRON ORE

摘要

AbstractA process for controlling the quality of sintered ironore in which the Fe++ content of the sintered ore is regulatedby controlling the recycled-fines feed rate. The recycled-finesfeed rate, determined by a prior art recycled-fines balance con-troller, is modified by a desired fines withdrawal rate generatedin an Fe++ content controller as the difference between theactual Fe++ content of the sintered ore and a desired content.In a preferred form, the difference between the recycled-finesfeed rate and the desired fines withdrawal rate is also appliedto the Fe++ content controller.
