Abstract

The invention discloses a micro carbon micro phosphorus aluminum manganese iron alloy used as steel-making deoxidizer. The composition of the alloy in weight percent contains 49-58% of aluminum, 1-4% of manganese, 38-50% of iron, less than 0.6% of silicon, less than 0.06% of carbon, less than 0.02% of phosphorus and less than 0.02% of sulphur. The alloy has good deoxidizing effect, and is especially suitable for deoxidization of low carbon, low manganese and low phosphorus steel types. Meanwhile, the impurity content of the alloy is very low, structure organization is more compact, air holes are less, and non-chalking period is longer, etc.

Description

technical field [0001] The invention relates to an aluminum-manganese-ferroalloy and a production method thereof, which is a steelmaking deoxidizer containing higher aluminum and lower manganese, carbon and phosphorus, and belongs to the field of iron and steel metallurgy. Background technique [0002] Deoxidation is an important process step in the production process of steel. Generally, ferrosilicon, pure aluminum or aluminum alloys are used as deoxidizers to reduce the oxygen content in molten steel from about 0.08% to about 0.005-0.01. Almanganese ferroalloy is a common composite deoxidizer. The aluminum content of traditional aluminum manganese ferrocomposite deoxidizers is 20-30%, and the manganese content is 30-60%. The aluminum content is limited, making this series of deoxidizers The agent does not have enough aluminum to increase the acid-soluble aluminum content of the steel. [0003] CN1614037A discloses a high-aluminum ferromanganese composite deoxidizer, alth...
