How to choose ferrosilicon powder 

How to choose ferrosilicon powder:

Raw materials to judge the quality of ferrosilicon powder: the raw materials of ferrosilicon powder come from ferrosilicon slag, but the raw materials for making ferrosilicon powder are still derived from the silica stone that makes ferrosilicon, and the impurity content and particle size of silica are important factors affecting the quality of ferrosilicon powder, so the selection of good ferrosilicon powder must first look at the quality of silica used to make ferrosilicon;

Coke quality to judge the quality of ferrosilicon powder: coke is also an important factor affecting the quality of ferrosilicon powder, coke used to produce ferrosilicon powder, the internal ash must be low, the content of water should be less, this is mainly because if the ash content inside the coke is high, it will affect the sintering of metallurgical materials Affect the permeability of ferrosilicon, and if the content of water is too high, it will make it difficult to control the temperature in the ferrosilicon powder furnace affecting the quality of ferrosilicon powder.
