The impurity is extremely low. Silver- gray and smooth surface.
?This product is with smooth surface and silver- gray. As the product is produced by submerged arc furnace, its deoxidization ability is high and accurate. Ferrosilicon is the essential deoxidizer and additive in the steelmaking industry, which can significantly improve the strength, hardness and flexibility of steel. It also raises the permeability of steel and reduces the magnetic belt spoilage of depressor steel. General silicon applies to the production of high- quality carbon steel and foundry industry with accordance to the international standard GB2272—87. Special silicon is applicable to high- grade silicon steel production. Low carbon low aluminum ferrosilicon apply to
