Abstract
A NiCuSiFe alloy prepared from Ni and Cu contained waste through resmelting contains Ni (25-60 wt%), Cu (25-60), Si (8-15), impurity (less than or equal to 0.2) and Fe (the rest), and can also be used as additive for smelting refractory steel, high-weatherability steel and other alloy steel. Its advantages are low smelting point, high dispersity and deoxidizing effect in molten steel and low cost.
Description
Technical field
The invention belongs to alloy technology.Being specifically related to a kind of is raw material with the secondary resource (waste material) that contains nickel and copper, the NiCuSiFe alloy that adopts remelting process to smelt.
Background technology
Along with the development of society, all trades and professions comprise that for high temperature steel, anti-Hou Gang and steel alloy the demand of freight container plate, sheet material steel and band steel etc. day by day obviously increases.NiCuSiFe alloy of the present invention then is an alloy addition of smelting a kind of novelty of above-mentioned steel grade.Because nickel and copper all have very strong toughness, and hand breaking is very difficult.Existing Alloying Treatment technology, all be with electrolytic nickel and electrolytic copper after cutting into piece, add molten steel by gravity flow in the high hopper, and make the stokehold Alloying Treatment.This stokehold Alloying Treatment of prior art, have following some deficiency at least: the one, make the alloy additive with electrolytic nickel and electrolytic copper, electric energy and auxiliary material in electrolytic nickel and the electrolytic copper production process have been wasted, and electrolytic nickel and electrolytic copper cost an arm and a leg, the resource anxiety, the production cost of using that then will promote steel-making enterprise; The 2nd, because single nickel element fusing point height, the diffustivity that enters in the pending molten steel is poor, in order to improve the uniform solid solubility of nickel in steel, and must fully stir, and has increased the difficulty of flushing and casting; The 3rd, through cutting caked electrolytic nickel and electrolysis copper billet, must in two high hoppers, store respectively, and will have two covering devices to control respectively, this is stokehold support equipment complexity not only, and operation is also cumbersome.And a kind of NiCuSiFe alloy is provided, just can fundamentally overcome the deficiency of above-mentioned prior art.If prepare NiCuSiFe alloy, then remain a kind of serious waste, and the production cost of prepared NiCuSiFe alloy certainty is very high with electrolytic nickel and the composite remelting of electrolytic copper.This is worthless equally.
Summary of the invention
Silicon is a kind of reductor.The deoxidizing capacity of silicon is between manganese and titanium.And the smelting of aforementioned high temperature steel, anti-Hou Gang and steel alloy except the deoxidation of molten steel purification is required, is not asked by it the content of silicon.Why nickel, copper and silicon will be put together, and produce the NiCuSiFe alloy additive, this is in order to realize that alloy is easy to fragmentation and reduces alloy melting point, improves the dual purpose of the diffusion of nickel in molten steel.
Purpose of the present invention is based on above-mentioned consideration, and make improvements at prior art, and provide a kind of low melting point, high diffusibility energy, have both deoxidation effect, be easy to fragmentation, make things convenient for flushing and casting, and be raw material with secondary resource (useless nickel, copper scrap), the NiCuSiFe alloy of taking remelting process to produce is to overcome the deficiency of prior art.
The object of the present invention is achieved like this, and it contains nickel, copper, silicon and iron, and unavoidable impurities such as carbon, phosphorus, sulphur, and their weight percentage is (%):
Nickel 25～60;
Copper 25～60;
Silicon 8～15;
Unavoidable impurities summation≤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 NiCuSiFe alloy of the present invention is (%):
Nickel 25～45;
Copper 25～45;
Silicon 10～15;
Carbon≤0.10;
Phosphorus≤0.03;
Sulphur≤0.03;
Iron surplus.
The NiCuSiFe alloy of above-mentioned preferred weight percentage has very high general usability.It is applicable to the stokehold alloy treatment of present fast-selling steel grade, is the present stage alloy addition expected of iron and steel enterprise.
And the weight percentage of each component of a kind of typical NiCuSiFe alloy of the present invention is (%):
Nickel 38～42;
Copper 38～42;
Silicon 10～12;
Carbon≤0.10;
Phosphorus≤0.03;
Sulphur≤0.03;
Iron surplus.
The NiCuSiFe alloy of above-mentioned typical weight percentage especially when the content of silicon is 12%, because of the fusing point that it had is special low good with the crushing performance spy, and has more practical value.
After last art technical scheme of the present invention is implemented, the fusing point that it had low (1100～1160 ℃), the diffusion in molten steel is good; Have both deoxidation effect; Be easy to fragmentation, the technology practicality is good; Adopting the secondary resource remelting to produce and characteristics such as production cost is low, is conspicuous.Compared with the prior art, the present invention has outstanding characteristics and marked 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:

Useless red copper material (as the copper scrap line) 160Kg of cupric more than 95.5%;
No. 75 ferrosilicon 67Kg;
Steel scrap 52Kg;
2, reparation technology process of the present invention is carried 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) add useless red copper material in batches, treat that it all stirs slagging-off in the fusing back;
(5) ingot bar of coming out of the stove;
It is (6) broken that (particle diameter is 10～100mm).
By above-mentioned batching and the NiCuSiFe alloy produced via above-mentioned technological process, the Chemical Composition through chemically examining it is (weight percentage %):
Nickel 40.56;
Copper 30.18;
Silicon 9.85;
The total amount 0.195 of unavoidable impurities such as carbon phosphorus sulphur;
Iron surplus.
The test example: the present invention is very convenient with the adz-eye hammer hand breaking; Show through steel mill is on probation, adopt the artificial directly addition method of ladle, convenience simple to operation; The recovery rate of nickel and copper is all more than 98.5%.
