Factors affecting the quality of ferrosilicon:
The factors affecting the quality of ferrosilicon are the goodness of the raw material, and the impurities in ferrosilicon often originate mainly from the ash carry-over of petroleum coke. Mineral heat furnace for the production of ferrosilicon can provide a temperature of 5000 ~ 8000K, which is used for the production of ferrosilicon aluminum oxide and other oxides to provide thermal and power conditions, raw materials in the aluminum oxide is reduced to ferrosilicon in the remaining some of the slag into the furnace.
In the production process of ferrosilicon 75, the aluminum content is generally between 1.5% -2.5%, the use of ferrosilicon refining technology can reduce the aluminum content of ferrosilicon, can be reduced by 0.1% so as to produce low aluminum ferrosilicon. The factors affecting the quality of ferrosilicon in the production of ferroalloys are diversified, and the good and bad raw materials directly affect the quality of ferrosilicon.
