How to prevent ferrosilicon pulverization?

In order to prevent ferrosilicate pulverization, the following three points should be noted:

1. The thickness of ferrosilicon ingot is not easy to be too thick, in order to reduce the segregation degree of ferrosilicon.

2. Strictly control the silicon content of ferrosilicon, not too low.Control ferrosilicon aluminum, phosphorus and calcium content, so to use better raw materials, especially can not use high ash coke, in order to reduce aluminum, phosphorus content, in order to reduce the calcium content of ferrosilicon, smelting should be as far as possible to reduce the addition of lime.

3.Ferrosilicate should be stored in the warehouse, strictly protected from rain.
