70 Ferrous Silicon Lumps

70 Ferrous Silicon Lumps combines with oxygen to form SiO2 during steelmaking, thus playing a deoxidizing role. Moreover, 70 Ferro Silicon releases a large amount of heat during steelmaking, which is conducive to increasing the temperature of molten steel.Our 70 Ferro Silicon is supplied in sizes 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized as per clients' requirements.

(1) Ferro Silicon 70 is an essential deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.
(2) Ferro Silicon 70 is used as an inoculant and spheroidizing agent in the cast iron industry. In ductile iron production, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizing agent.
(3)Ferro Silicon 70 is used as a reducing agent in ferroalloy production. Not only is there a great chemical affinity between silicon and oxygen, but high silica ferrosilicon has a very low carbon content. Therefore, high silica ferrosilicon (or siliceous alloy) is a kind of reducing agent commonly used in the production of low-carbon ferroalloys in the ferroalloy industry.
(4) Ground or atomized processed ferrosilicon powder in the welding rod manufacturing industry can be used as a coating for welding rods. High silica ferrosilicon can be used in the chemical industry to manufacture products such as silicone.
