70% Ferro Silicon

70% Ferro Silicon is a large group of alloys of the Fe-Si system and is intended primarily for deoxidation and alloying of steel. It is widely used in the foundry industry for the production of iron and steel castings. Pieces of 70 Fesi should be free of slag, sand, and other materials, both on the surface and in the fracture. Only the presence of an oxide film and traces of non-stick materials are allowed.

Packaging Details: packed in water-proof plastic woven bag, 1000kg per bag or as your requirements.
Delivery Time: Within 15 days after receipt 30% T/T in advance.
Remark: Chemical composition and size can be optimized by the customers' requirements

The main benefit of FeSi 70 is its deoxidizing effect (i.e. it reduces metals from their oxides), but it also helps prevent carbon loss. In addition, ferrosilicon is used in electrode coatings and in the production of silicon, hydrogen and magnesium. Ferrosilicon is produced either in a blast furnace or in an electric arc furnace by reducing quartz sand (SiO2) with coke in the presence of iron. The melt is poured out of the furnace and solidifies into a flat sheet. After cooling, this sheet is crushed using appropriate equipment and then further processed in a crusher. The resulting size distribution ranges from fine dust particles to centimeter-sized pieces. FeSi is screened into different size grades for further use.
