Abstract: The progress of ferrosilicon smelting technology is summarized from the aspects of ferrosilicon smelting principle and new ferrosilicon smelting technology (including new smelting ore furnace and new smelting raw materials).Introduces the application of ferrosilicon in metallurgical field (can be used as deoxidizer,alloying agent,inoculant,nodularizer,reducing agent,etc.),mineral processing industry,hydrogen production industry,electrode materials for lithium-ion batteries,etc.The future development direction of ferrosilicon is prospected,which provides a reference for the wide application of ferrosilicon.

Key words: Ferrosilicon, Smelting, Application, Research progress
