Abstract

The present invention discloses Ni-Si-Fe alloy which is prepared by remelting a secondary resource, namely nickeliferous waste material, which belongs to alloying technology. The Ni-Si-Fe alloy comprises components and weight percent contents thereof as follows: 50% to 70% of Ni and 8% to 16% of Si; besides, the total quantity of impurities, such as C, P, S, etc. is smaller than or equal to 0.20%, and the rest is Fe. The present invention has the characteristics of low melting point, good diffusion performance in molten steel, deoxidation effect, easy fragmentation, good technologic practicability, low preparation cost, convenient on-the-spot operation, etc. Therefore, the Ni-Si-Fe alloy is a substitute for alloy additive electrolytic nickel for smelting Ni and Si containing stainless steel at present.

Description

NiSiFe alloy
Technical field
The invention belongs to alloy technology, specifically be a kind of NiSiFe alloy of producing with the useless nickel remelting of secondary resource.
Background technology
NiSiFe alloy is steel mill's nickeliferous siliceous stainless alloy addition of smelting in short supply at present.
Prior art is done to add the nickelalloy processing to molten steel, be to adopt the stripping and slicing electrolytic nickel, via high hopper under the control of control device, the method that in molten steel, adds.And still following so far by manually adding the stripping and slicing electrolytic nickel in minority steel mill, molten steel is done to add the nickelalloy processing.Take a broad view of the method for the interpolation electrolytic nickel Alloying Treatment of prior art, at least exist following some deficiency: the one, adopt electrolytic nickel to make the alloy additive, owing to the low-temperature high-toughness of nickel is difficult to broken, have to take the cut mechanically method, it is standby that electrolytic nickel is cut into plate, and this has just increased trouble to steel-making enterprise; The 2nd, because electrolytic nickel costs an arm and a leg, the resource anxiety, and promoted the production cost of steel-making enterprise; The 3rd, electrolytic nickel fusing point height, the diffusion in molten steel is poor, and has increased the difficulty of flushing and casting to Alloying Treatment.And a kind of NiSiFe alloy additive is provided, just can fundamentally overcome the deficiency of above-mentioned prior art.Certainly prepare NiSiFe alloy with the composite remelting of electrolytic nickel, then remain a kind of serious waste, and the production cost of prepared NiSiFe alloy is inevitable very high.This is worthless equally.
Summary of the invention
Silicon is a kind of reductor.Silicon also is the fusing point that nickeliferous siliceous stainless alloy addition, particularly silicon can effectively reduce NiSiFe alloy simultaneously, and improves the diffustivity of nickel in molten steel; And can allow NiSiFe alloy be easy to fragmentation, improve its technology practicality; Simultaneously, silicon can be brought into play its deoxidation, purification function again in molten steel.
Purpose of the present invention is based on above-mentioned consideration, make improvements at prior art, and a kind of low melting point is provided, the high diffusibility energy has both deoxidation effect, be easy to fragmentation, make things convenient for flushing and casting, and be raw material with secondary resource (waste nickel material such as nickel screen, the useless angle of nickel plate material etc.), the NiSiFe alloy of taking remelting process and producing is to overcome the deficiency of prior art.
The object of the present invention is achieved like this, and it contains nickel, silicon and iron, and unavoidable impurities such as carbon, phosphorus, sulphur, and their weight percentage is (%):
Nickel 50~70;
Silicon 8~16;
Unavoidable impurities total amount≤0.20 such as carbon phosphorus sulphur;
Iron surplus.
Because further improve technology practicality of the present invention and obtain more ten-strike of coml, the weight percentage of each component of the preferred NiSiFe alloy of the present invention is (%):
Nickel 50~65;
Silicon 8~12;
Unavoidable impurities total amount≤0.20 such as carbon phosphorus sulphur;
Iron surplus.
The NiSiFe alloy of above-mentioned preferred weight percentage, it has very strong general usability.It is a kind of alloy addition that can satisfy the stokehold Alloying Treatment of present fast-selling steel grade.
And the present invention is in order to reduce its fusing point to greatest extent and to improve its crushing performance, and in the hope of further improving practical value of the present invention, the weight percentage of each component of a kind of typical NiSiFe alloy of the present invention is (%):
Nickel 55~60;
Silicon 10~12;
Unavoidable impurities total amount≤0.20 such as carbon phosphorus sulphur;
Iron surplus.
In the typical weight percentage composition of the invention described above, when its silicon content was 1 2%, fusing point then of the present invention can be reduced to 1180 ℃.
The present invention has fusing point low (1180 ℃~1240 ℃), and the diffusion in molten steel is good; Be easy to fragmentation, the technology practicality is good; Have both deoxidation effect; Adopting the secondary resource remelting to produce and characteristics such as production cost is low, is apparent.Compared with the prior art, the present invention has outstanding characteristics and obvious improvement.
Embodiment
With 0.5t middle frequency furnace and every batch of total charging capacity is that 500Kg is an example.
1, the elder generation that produces of the present invention is standby by following weight batching:
Nickeliferous useless nickel material (as nickel screen) 290Kg more than 95%
No. 75 ferrosilicon 67Kg
Steel scrap 143Kg
2, preparation process of the present invention carries out as follows:
(1) adds steel scrap intensification fusing;
(2) add useless nickel and it is melted as early as possible;
(3) in melting process, add ferrosilicon;
(4) treat that furnace charge all melts the back and stirs, removes the gred;
(5) ingot bar of coming out of the stove;
It is (6) broken that (particle diameter is 10~100mm).
By above-mentioned batching and by the Chemical Composition of the prepared NiSiFe alloy of above-mentioned processing step is (weight percentage %):
Nickel 55.03;
Silicon 9.96;
Unavoidable impurities total amounts 0.180 such as carbon phosphorus sulphur;
Iron surplus.
The test example: fragmentation of the present invention is very light; Show that adopt the artificial directly addition method convenience simple to operation of ladle, the recovery rate of nickel reaches more than 98.5% through steel mill is on probation.
