How To Choose Silicon Iron Powder

Judging the quality of ferrosilicon powder by raw materials: The raw materials for ferrosilicon powder come from ferrosilicon slag, but the raw materials for producing ferrosilicon powder still come from the silica used for producing ferrosilicon. The impurity content and particle size of silica are important factors that affect the quality of ferrosilicon powder. Therefore, selecting a good ferrosilicon powder first depends on the quality of the silica used for producing ferrosilicon;
Judging the quality of ferrosilicon powder based on the quality of coke: Coke is also an important factor affecting the quality of ferrosilicon powder. The internal ash content of coke used for producing ferrosilicon powder must be low, and the water content should also be low. This is mainly because if the ash content inside the coke is high, it will affect the sintering of metallurgical materials and affect the permeability of ferrosilicon. If the water content is too high, it will make it difficult to control the temperature in the ferrosilicon furnace and affect the quality of ferrosilicon powder.
