Abstract
The silicon-aluminium-barium-strontium-iron alloy for deoxidizing steel has chemical components including Si25-40, Al20-30, Ba6-15, Sr4-10 and Fe for the rest. The silicon-barium-strontium-iron alloy is smelted into the silicon-barium-strontium-iron alloy by one-time smelting, and the silicon-aluminum-barium-strontium-iron alloy is smelted into the silicon-aluminum-barium-strontium-iron alloy by adding aluminum and iron for two times, is used for steelmaking deoxidization, and has the effects of grain refinement and aluminum saving.
Description
The present invention relates to metallurgy, be specially a kind of iron alloy that deoxidation in steel making uses and preparation method thereof.
It is 89109528.4 a kind of complex deoxidizer for steelmaking si-al-ba-fe that Chinese patent CN1052901A discloses application number.The chemical ingredients of this alloy is Si22-28%, Al30-40%, Ba3-12%, Fe surplus.Though the original compound deoxidant of ferrosilicoaluminum that uses of this alloy has performance and the joint aluminium effect that reduces the non-metallic inclusion total amount, changes inclusion shape, size and distribution, the performance of its crystal grain thinning is not ideal enough; In addition, its aluminum content is still more than 30%.
The object of the present invention is to provide a kind of steel-making alloy reductor and preparation method thereof that has crystal grain thinning and aluminum content is further reduced.
Alloy reductor provided by the invention increases Preparation of Metallic Strontium except that containing the Si-Al-Ba-Fe composition.Concrete chemical ingredients (weight ratio) is: Si25-40%, Al20-30%, Ba6-15%, Sr4-10%, Fe surplus.
The preparation method of alloy reductor of the present invention is first by raw material weight proportioning quartzite 20-45%, barite 5-15%, and lazurite 5-20%, iron filings 1-5%, Wingdale 0.5-5%, fluorite 0.5-2%, coke 20-35% smelts silicon-barium-strontium-iron alloy in the hot stove in ore deposit; And then with this silicon-barium-strontium-iron alloy secondary smelting in induction furnace becomes silicon-aluminum-barium-strontium-iron alloy with aluminium and iron.
With the reductor of silicon-aluminum-barium-strontium-iron alloy do smelting U71Mn steel provided by the invention, with the si-al-ba-fe reductor comparison (under the consumption same case) of original use, high-melting-point Al in the steel
2O
3Inclusion content reduces to 0.0016% by original 0.0018%; Autstenitic grain size accounts for 75%, 8 grade by original 7 grades and accounts for 25% and bring up to 7 grades and account for 25%, 8 grade and account for 75%.Obviously, the performance of its crystal grain thinning obviously improves; Simultaneously, the content of aluminium further reduces in the iron alloy of the present invention, further saves aluminium 5-10% on the basis of Si-Al-Ba-Fe reductor.
Embodiment 1
Prepare burden by weight percentage: quartzite (contains SiO
2More than 99%) 35%, barite (contains BaSO
4More than 85%) 10%, lazurite (contains SrSO
4More than 80%) 15%, iron filings 5%, Wingdale 4%, fluorite 1%, coke 30% is smelted into silicon-barium-strontium-iron alloy in the hot stove in adding 1800KVA ore deposit, then by this alloy 50%, aluminium 22%, the ratio of components batching of iron 28%, secondary smelting becomes Si25% in induction furnace, Al20%, Ba6%, Sr4%m, the silicon-aluminum-barium-strontium-iron alloy of Fe45%.
Embodiment 2
Processing step is identical with embodiment 1, and only ratio of components is a quartzite 38%, barite 12%, lazurite 15%, iron filings 3%, Wingdale 1.5%, fluorite 0.5%, coke 30%; Silicon-barium-strontium-iron alloy 58% during secondary smelting, aluminium 27%, and iron 15% finally can obtain Si30%, Al25%, Ba10%, Sr30%, the alloy of Fe27%.
Embodiment 3
Processing step is identical with embodiment 1, and only ratio of components is a quartzite 40%, barite 14%, lazurite 16%, iron filings 1%, Wingdale 0.5%, fluorite 0.5%, coke 28%; Silicon-barium-strontium-iron alloy 65% during secondary smelting, aluminium 32%, and iron 3% finally can obtain Si40%, Al30%, Ba15%, Sr10%, the alloy of Fe5%.
Claims (2)
1, be used for the silicon-aluminum-barium-strontium-iron alloy of steel-deoxidizing, it is characterized in that, its chemical ingredients (weight ratio) is Si25-40%, Al20-30%, Ba6-15%, Sr4-10%, Fe surplus.
2, as the preparation method of the said silicon-aluminum-barium-strontium-iron alloy of claim 1, it is characterized in that, press earlier raw material weight proportioning quartzite 20-45%, barite 5-15%, lazurite 5-20%, iron filings 1-5%, Wingdale 0.5-5%, fluorite 0.5-2%, coke 20-35% smelts silicon-barium-strontium-iron alloy in the hot stove in ore deposit; And then this alloy become silicon-aluminum-barium-strontium-iron alloy with aluminium and iron secondary smelting.
