Low aluminum ferro silicon smelting

The production of low-aluminum ferro silicon is based on natural silica as raw material, using metallurgical coke as a reducing agent and adding a certain amount of iron-containing material to smelt in a submerged thermal electric furnace. The iron-containing materials in the production of low-aluminum ferro silicon are all carbon steel scraps, and the amount added in the production process is less than that of silica and coke, but the particle size of the steel scraps is difficult to guarantee, and the final result cannot guarantee the steel scraps in the furnace. The distribution of the resistance value in the furnace is uniform, resulting in uneven distribution and frequent fluctuation of the resistance value in the furnace, and it is difficult to stabilize the consistency of the electrode and alloy composition. A new method for smelting low-aluminum ferro silicon that can reduce power consumption and coke consumption. A new method for smelting low-aluminum ferro silicon: all iron-containing materials composed of oxides such as Fe2O3, Fe3O4 and FeO are used to replace steel scraps. Form the smelting charge. In the process of smelting low-aluminum ferro silicon, the area of the furnace mouth automatically sinking material is enlarged, and the sinking material is uniform. Because the electrode is deeply inserted into the furnace material, the operation of the furnace mouth low material line is ensured. , the heat loss is small. Compared with the prior art, the method uses iron oxide material instead of steel scraps to smelt low-aluminum ferro silicon, which has the effect of significantly reducing power consumption, coke consumption and the like than using steel scraps to smelt low-aluminum ferro silicon.
