Factors Affecting The Quality Of Ferrosilicon

The quality of ferrosilicon is influenced by the quality of raw materials, and the impurities in ferrosilicon are often mainly brought in by the ash of petroleum coke. The submerged arc furnace used to produce ferrosilicon can provide a temperature of 5000~8000K, which provides heat and power conditions for oxides such as aluminum oxide used in the production of ferrosilicon, and the aluminum oxide in the raw material is reduced to silicon Some of the remaining iron goes into the slag. In the production process of ferrosilicon 75, the aluminum content is generally between 1.5% and 2.5%. Using ferrosilicon refining technology can reduce the aluminum content in ferrosilicon, which can be reduced by 0.1% to produce low aluminum ferrosilicon. The factors affecting the quality of ferrosilicon in ferroalloy production are diverse, and the quality of raw materials directly affects the quality of ferrosilicon.
