Ferrosilicon aluminum

Si - Al - Fe is a compound strong deoxidizer.

Grade: FeAl52Si5/FeAl37Si20and etc.
Size: Lump/Grain/Powder

Si-al-fe alloy is a kind of deoxidizer used in steelmaking. It is an effective new technology to improve the quality of steel, reduce the cost and save aluminum by improving the inclusions and reducing the content of gas elements in liquid steel. According to the raw material treatment method, there are two kinds of ore reducing agent, directly into the furnace after batching and first through mass treatment and then into the furnace.

Silicon Aluminum Iron Use

Silicon aluminum and iron in the steelmaking industry can improve some of the mixed with some stuff, but also reduce the gases in the molten steel element, has the very good products, to improve the quality of steel can improve steel quality can also reduce the cost, and can save use of new technology of aluminum so well suited for use in steelmaking, and also got a very wide range of applications. Continuous casting steel deoxidation requirements, the practice has proved that it not only meets the requirements of steel deoxidation, but also has the desulfurization performance and has the advantages of heavy, strong penetration and so on.

Si-al-ferroalloy is a strong deoxidizer and a reducing agent in the production of other metals and alloys. It is also used in thermite welding, the manufacture of heating agents and explosives.
