The simplex algorithm was adopted to solve this model. Four kinds of imported iron ores, two kinds of Chinese iron ore concentrates, and two kinds of fluxes were selected to verify both the model and the algorithm. The results confirmed the possibility of considering both chemical compositions and high-temperature characteristics of iron ores in the optimization model. This model provides a technical roadmap to obtain a precise mathematical correlation between the lowest cost and the grade of iron in sinters based on the condition of given raw materials, which can provide a reference to adjust the grade of iron in the sintering process for enterprise.展开更多

By using burden calculation andsimulating production under different situations, it is demonstrated that the technology can providethe relevant information in product quality and cost etc. for decision-makers. The technology hasbeen used to guide production of the Sinter Shop since 2000, and a remarkable achievement has beenobtained.展开更多
