Optimal proportioning of iron ore in sintering process …
Proportioning is an important part of sintering, as it affects the cost of sintering and the quality of sintered ore. To address the problems posed by the complex raw material information and numerous constraints in the sintering process, a multi-objective optimisation model for sintering proportioning was established, which takes the proportioning cost and TFe …
