Ferrosilicon 75% HP (High Purity) is an alloy which is produced by combining around 75% of Silicon and 25% of iron. This product is manufactured from selected raw material with high purity degree and rigorous quality control, which guarantees wide homogeneity among lots. This grade is used in the production of grain-oriented electrical steel as well as steels requiring low level of Aluminum, Carbon, Calcium, titanium, boron and other residual elements. This product is used in grades of steel where high purity, low residual input are required. Destined to the production of electrict transformer scores, power generators and other electrict equipment. High Purity 75%Ferro Silicon is used in the fabrication of special steel, among them, the guided and non-guided grain silicon, applied in the fabrication of transformer cores, power generators and other electric equipment. The raw materials are selected and classified according to their physical-chemical characteristics. These raw materials are properly weighed and sent to the reduction process in Electric Submerged Arc Furnaces. Inside the Electric Furnaces, chemical reactions of reduction of quartz and iron source by coal occur through insertion of the heat source. Electric power is introduced into the Electric Oven via a carbon-based electrode.
