How To Prevent Ferrosilicon From Powdering?

1. The thickness of the ferrosilicon ingot should not be too thick to reduce the degree of segregation of silicon content in the ferrosilicon.
2. Strictly control the silicon content of ferrosilicon, not too low. Control the aluminum, phosphorus and calcium content of ferrosilicon. For this purpose, better raw materials must be used, especially high-ash coke cannot be used to reduce the aluminum and phosphorus content. In order to reduce the calcium content of ferrosilicon, the addition of lime should be minimized during smelting. .
3. Ferrosilicon should be stored in a warehouse and protected from rain.
