Abstract
A SGBaCaMnMgFe alloy for smelting steel is prepared from Si (20-60 wt.%), Ba (15-35), Ca(1-16), Mg (1-16), Mn (1-50) and Fe (rest) through conventional carbon reduction method or resmelting method.
Description
Technical field
The present invention relates to a kind of alloy, relate in particular to a kind of silicon barium calcium manganese magnesium iron Alloy And Preparation Method that is used for deoxidation in steel making and alloying, belong to field of metallurgy.
Background technology
The patent No. be ZL 03111473.3 patent disclosure a kind of silicon calcium barium calcium manganese iron alloy that is used for deoxidation in steel making and alloying, this alloy can make steel liquid deoxidation and one step of alloying finish, also have simultaneously certain deoxidation and sweetening effectiveness, but it is to be overcome that this alloy in use exists following defective to have: the ability of its deoxidation and desulfurization has much room for improvement, and exists the mechanical property of more impurity, steel also to have much room for improvement in the steel of being smelted.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of alloy that a kind of deoxidation and sweetening effectiveness are good, can improve the steel mechanical property is provided.
Technical problem to be solved by this invention realizes by following technological approaches: a kind of alloy that is used for deoxidation in steel making and alloying, make by following raw materials by weight percent:
Silicon (Si) 20～60%, barium (Ba) 5～35%, calcium (Ca) 1～16%, magnesium (Mg) 1～16%, manganese (Mn) 1～50%, surplus is Fe and inevitable impurity.
Be preferably: silicon (Si) 30～50%, barium (Ba) 10～25%, calcium (Ca) 1～10%, magnesium (Mg) 1～10%, manganese (Mn) 5～40%, surplus is Fe and inevitable impurity.
More preferably: silicon (Si) 35%, barium (Ba) 12%, calcium (Ca) 4%, magnesium (Mg) 4%, manganese (Mn) 15%, surplus is Fe and inevitable impurity.
Added the magnesium of 1～30wt% in the alloy of the present invention, the magnesium chemically reactive is strong, very strong with the binding ability of oxygen in the steel and sulphur, can form stable compound, deoxidation effect is stable, fluctuation is little, is significantly improved so the deoxidation of alloy of the present invention is compared with existing silicon calcium barium calcium manganese iron alloy with sweetening power; In addition, magnesium still has the effect of the uniformity coefficient that improves the steel crystal structure, crystal grain thinning, reduction inclusion total amount, so the steel that adopt alloy of the present invention to smelt have good comprehensive mechanical performance.
The following ore of the optional usefulness of the used raw material of the present invention: silica (SiO
2＞98%), lime (CaO＞82%), barite (BaCO
3＞91%), rhombspar (MgO＞16%), manganese ore (containing Mn45～60%), firm bits.
Alloy of the present invention can adopt conventional carbon reduction method or heavy molten method preparation.
Carbon reduction method: raw material dropped in proportion reducing and smelting forms in the hot stove in ore deposit, reductive agent is coal and coke.
Heavy molten method: silicon calcium barium calcium manganese iron and magnesium are heated remelting form in middle frequency furnace.
Further illustrate beneficial effect of the present invention by the following examples, it should be understood that these embodiment only are used for the purpose of illustration, never limit the scope of the invention.
