Ferro Silicon
Ferro Silicon Size: 10-50mm,20-80mm,50-100mm or customized Packing: 1mt big bags or as per buyer's requirement Ferro Silicon is mainly used as a deoxidizer in the steel making industry, in order to obtain chemical composition of qualified steel and to improve the quality of steel. Also it is used as inoculants and nodulizers in the cast iron industry and as a reducing agent in ferro alloy production. In addition it is used as welding electrode coating in the electrode manufacturing industry.
Ferro silicon 75 Ferro silicon 75 is widely used in steel making and casting. In the steelmaking process, the steel needs to be oxygenated to achieve the ideal high temperature environment, and too much oxygen at a later stage tends to produce more oxides in the steel, which affects the quality of the steel. At the same time, ferro silicon 75 can also effectively promote the fluidity of the steel, improve the absorption rate, reduce the production cost and increase the profit margin of the steel mill.
Uses of ferro silicon 75: (1) Ferro silicon 75 is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferro silicon 75 is used for precipitation deoxidation and diffusion deoxidation. (2)Ferro silicon 75 is used as an inoculant and spheroidizing agent in the cast iron industry. In the production of nodular cast iron, 75 ferro silicon is an important inoculant (helping to precipitate graphite) and nodulizer. (3)Ferro silicon 75 is used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is great, but the carbon content of high-silicon ferro silicon 75 is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a commonly used reducing agent in the production of low-carbon iron alloys in the ferroalloy industry. (4) 75 ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pidgeon method of magnesium smelting. The magnesium in CaO. MgO is replaced, and each ton of metal magnesium will consume about 1.2 tons of ferrosilicon. The production of magnesium metal plays a big role. FERRO SILICON 75 APPLICATION: Ferro silicon 75 is widely used in steel making and casting. In the steelmaking process, the steel needs to be oxygenated to achieve the ideal high temperature environment, and too much oxygen at a later stage tends to produce more oxides in the steel, which affects the quality of the steel. At the same time, ferro silicon 75 can also effectively promote the fluidity of the steel, improve the absorption rate, reduce the production cost and increase the profit of the steel mill. Ferro silicon 75 can also be used as an alternative to inoculants in casting to enhance the formation and increase the number of eutectic pellets. The addition of ferro silicon 75 in the production of ductile iron can effectively prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite. It can effectively improve the fluidity of the iron, thus preventing clogging of the outlet and reducing the tendency of white mouth of the casting. Ferrosilicon composition table.
Element content
Ferrosilicon is a kind of ferroalloy that is composed produced by reduction of silica or sand with coke in the presence of iron. Typical sources of iron are scrap iron or milscale. Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.The usual formulations on the market are ferrosilicons with 60-75% silicon, The remainder is iron, with about 2% consisting of other elements like aluminum and calcium, An overabundance of silica is used to prevent formation of silicon carbide.
Application Ferro silicon 72 75 is widely used as deoxidizer and alloy additive in steelmaking. Ferro silicon powder emits a lot of heat in steel making production, and is used as a heating agent for steel ingot caps to improve the recovery rate and quality of steel ingots. Ferrosilicon can be used as inoculant and nodulizer for cast iron. High silicon content ferrosilicon alloy is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry. Ferrosilicon powder or atomized ferrosilicon powder can be used as coating for welding rod production. Ferrosilicon can be used for high-temperature smelting of magnesium metal. 1 ton of metallic magnesium needs to consume about 1.2 tons of ferrosilicon.
