Production of Ferro-Silicon – IspatGuru

 · The cast material is removed from the moulds when it has cooled down to a level where the material strength is high enough to be removed and stacked in piles for further cooling. After cooling and solidification, the Fe-Si is crushed and screened to produce the required lump sizes. In the process of crushing, some fines are generated.
