Factors affecting the quality of ferrosilicon

Factors affecting the quality of ferrosilicon:

The influencing factor of the quality of ferrosilicon is the quality of raw materials, and the impurities in ferrosilicon are often mainly derived from the ash of petroleum coke. The ore furnace used for the production of ferrosilicon can provide a temperature of 5000 ~ 8000K, which provides thermal and dynamic conditions for oxides such as aluminum trioxide used for the production of ferrosilicon, and the aluminum trioxide in the raw material is reduced to the remaining part of the ferrosilicon and enters the slag. In the production process of ferrosilicon 75, the content of aluminum is generally between 1.5% and 2.5%, and the use of ferrosilicon refining technology can reduce the content of aluminum in ferrosilicon, which can be reduced by 0.1% to produce low aluminum ferrosilicon. The factors affecting the quality of ferrosilicon in the production of ferroalloys are diverse, and the quality of raw materials directly affects the quality of ferrosilicon.

The above are some suggestions, I hope to help you!
