Parameters of submerged arc furnace (SAF) for ferroalloy can be divided into equipment parameters and smelting parameters. After the determination of the equipment parameters, how to optimize the smelting parameters of SAF is the key problem. This paper first analyzes the nature of smelting parameters optimization of SAF, and points out the design formula can not be directly used to describe the relation between smelting parameters. Finally, it introduces Westly and Jaccard formulas of smelting parameters, and demonstrates that Westly formula can not be used to...
