Smelting steps of ferrosilicon alloy

The smelting steps of ferrosilicon alloy are as follows:
1. Select raw materials such as silica, blue carbon or coke, and iron oxide scale; Crush and clean the silica for later use; Set aside the blue carbon sieve powder or crush the coke and sieve the powder for backup;
2. According to the composition content of the raw materials and the type of ferrosilicon alloy to be produced, ingredients and mixtures are made in the proportion of 200kg of silica, 120-130kg of blue carbon or coke, and 38-65kg of oxide scale;
3. Continuous batching according to the proportion described in step 2, mixing evenly and then feeding into the submerged arc furnace, and smelting according to conventional smelting conditions and operations; During the feeding operation, make the oxide scale located in the triangular part of the electric furnace or the upper part of the furnace material;
4. Pouring out of the furnace;
5. Produce ferrosilicon alloy. Ferrosilicon is an important raw material for steel smelting, and the quality of ferrosilicon affects the quality of steel
