ferro silicon 70 is mainly reflected in its effective use of waste silica fume and small particles of silica in the production process of ferroalloy industry. By pelletizing these wastes as a silicon source, 70 ferrosilicon alloys can be produced, which not only solves the problem of waste disposal, but also provides a new source of raw materials for the production of ferroalloys. This method provides an effective way to utilize the waste silica fume and small particles of silica in the production process of the ferroalloy industry, which has important environmental significance and economic benefits.

1.Ferro silicon 70 is special in that it is produced using silica fume and small silica pellets as silicon sources. This method provides an effective way for the ferroalloy industry to utilize, especially for silica fume and small particles of silica that are discarded in the ferroalloy production process. The ferrosilicon 70 alloy produced by this method is not only environmentally friendly, but also cost-effective, making full use of industrial waste and realizing the reuse of resources. In addition, ferrosilicon 70 alloy is used as an indispensable deoxidizer in the steelmaking industry, including but not limited to low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. These uses and properties of ferrosilicon 70 make it one of the indispensable materials in steel production.
