Abstract: Two methods to obtain a proper iron ores matching scheme were put forward. Sinter quality simulating model and optimizing iron ores matching model were built by using BP neural network technology and genetic algorithms technology, respectively. In addition, the software of optimizing matching ores system model was developed using a mixing programming mode of Visual C++ 6.0 development tool and Matlab programming language. The results show that the sinter quality simulating model has good generalization and self-adaptation abilities. Moreover, this model has a high predictive hit-ratio. The predictive hit-ratio for tumbler strength, abrasion strength and screen index are 90%, 86.67% and 83.33%, respectively. The optimizing iron ores matching model can give the best iron ores matching scheme, which makes the cost lower and the quality of sinter good. The optimizing iron ores matching model has a good optimizing effect. The software of optimizing matching ores system model has some advantages such as good practicability, as well as powerful functions of storage, calculation, prediction and optimization. Key words: sintering; optimization iron ores matching; model of sinter quality; optimizing iron ores matching model
