ferrosilicon ball

The ferrosilicon ball is made by pressing ferrosilicon powder and ferrosilicon granules, and the cost is reduced under the condition of the same composition. Mainly used in steel slag re-smelting pig iron, ordinary casting, etc. Ferrosilicon balls can well increase the furnace temperature, increase the fluidity of molten iron and effectively discharge slag, increase the label, and improve the toughness and cutting ability of pig iron and castings.
