70 Ferro Silicon Granules

 

70 Ferro Silicon Granules are produced industrially by carbo-thermic reduction of silicon dioxide (SiO2) with C. It is produced by smelting Fe-containing materials and Si-containing materials. Fe is in the form of iron ore, iron or steel scrap, or mill scale and Si is normally in quartzite lumps. These are combined with carbonaceous material such as coal or petroleum coke and a bulking agent such as wood chips. Quartzite is the source of Si in this carbo-thermic process. The smelting of Fe-Si is a continuous process carried out in the electric submerged arc furnace (SAF) with the self-baking electrodes.

All grades of Fe-Si are produced using essentially the same process, but certain additional steps are required to produce higher?purity grades of Fe-Si. Such grades are produced using raw materials containing lower amounts of impurities. In addition, refinement of the liquid Fe-Si to remove unwanted impurities and the addition of special alloying elements occur in the ladles. This further processing to produce higher purity Fe-Si is known as ladle metallurgy. Specialty grade 15 % Fe-Si for dense medium application is typically produced by remelting 75 % Fe-Si with steel scrap in an electric arc furnace and casting into a high?pressure water spray.
