Certain components of ferrosilicon are sometimes exposed to water or air humidity is too high during storage. At the same time, the content of aluminum, calcium and phosphorus impurities is high. After a certain period of time, ferrosilicon will pulverize. In severe cases, it may even burn. Phenomenon.
Ferro Alloy Supplier
Improper amounts of aluminum, phosphorus and calcium in ferrosilicon will all contribute to powdering of ferrosilicon. When the aluminum and phosphorus contents increase to a certain value at the same time, this ferrosilicon is prone to powdering in air with high humidity. Some data point out that the phosphorus content in ferrosilicon is less than 0.04% and the aluminum content is less than 3%, so it is not easy to cause powdering.
Low carbon ferrosilicon Supplier
In ferrosilicon, the temperature of FeSi, FeSi2 and other silicon and iron compounds decreases and the volume expands, causing ferrosilicon to pulverize. Ferrosilicon containing aluminum forms aluminum hydroxide and generates gas when it meets water, which is the main reason for the powdering of ferrosilicon.
