Abstract
A fragile NiCuSi alloy for alloying molten steel contains Ni (35-46 wt.%), Cu (35-46) and Si (8-20). It features good brittleness and control of harmful impurities (such as P, S, Pb, Sn and Zn).
Description
Technical field
The present invention relates to a kind of alloying agents of making steel usefulness, particularly a kind of frangible nickel-copper-silicon alloy.
Background technology
Produce nickeliferous and/or copper bearing steel, during as stainless steel, pipe line steel, all will in molten steel, add metallic nickel and/or metallic copper.Traditional nickel that is used for alloying and/or copper generally are metal nickel plate or copper coin.Along with the development of steel-smelting technology, the automatization feeding equipment that has automatic weighing and adding apparatus is widely used among the steel mill.Traditional nickel plate and copper coin be not owing to size is suitable for this kind equipment greatly, thereby need carry out nickel plate, copper coin, and Jian cuts, break process.Because nickel and copper have good toughness and ductility, thereby specific equipment need be set they are processed into fritter, this certainly will strengthen steel-making cost.If providing a kind of is easy to broken nickel-copper alloy then can eliminates above-mentioned shortcoming.In addition, because nickel and copper are expensive metal, should produce described nickel-copper alloy with the nickel and the copper that reclaim as far as possible, the surplus of the harmful element in the control alloy is again an essential difficult problem that solves.
Summary of the invention
The object of the present invention is to provide a kind of frangible nickel-copper-silicon alloy that is used for the molten steel alloying, it contains (weight %):
Ni：35～46％，Cu：35～46％，Si：8～20％。
Described nickel-copper-silicon alloy also comprises (weight %):
C smaller or equal to 0.10%, the P smaller or equal to 0.05%, S, Sn, the Pb smaller or equal to 0.3% and smaller or equal to 0.3% the Zn and the Fe of surplus smaller or equal to 0.5% smaller or equal to 0.04%.
As previously mentioned, metallic nickel and copper and alloy thereof are difficult for fragmentation owing to having good toughness and ductility, in order to improve the fragility of nickel-copper alloy, can make this alloy contain 8～20% Si.The Ni-Cu alloy that contains 8～20%Si has good fragility, can use simple method, as hand bumping with its fragmentation.In addition, Si is a deoxidant element commonly used in the steelmaking process, contains Si in the alloy, and the molten steel that carries out alloying with this alloy is not had any disadvantageous effect.
For satisfying the requirement of steel-smelting technology standard, the reply detrimental impurity is controlled, and the detrimental impurity that is included in the Ni-Cu-Si alloy of the present invention comprises, S, P, Pb, Sn and Zn.Yet the content that needs only them is controlled at (weight %) respectively:
S≤0.04％，P≤0.05％，Pb≤0.3％，Sn≤0.5％，Zn≤0.3％。
Just can satisfy the requirement of steel-smelting technology standard.
The smelting technology step of Ni-Cu-Si alloy of the present invention is as follows:
1, prepares burden according to the target composition;
2, will meet ratio of components, mainly be place induction furnace to melt through nickel and copper that recovery gets;
3, treat to add ferrosilicon behind the furnace charge fine melt;
4, the impurity such as silt particle that bring with the removal raw material with lime and fluorite slag making;
5, behind the accurate adjustment composition alloy is poured out;
6, be broken into the granularity that needs after the cooling by hand.
Ni-Cu-Si alloy of the present invention has good fragility, can be broken into required granularity by hand at an easy rate, to satisfy the requirement of automatization feeding equipment.
Ni-Cu-Si alloy of the present invention owing to selecting materials, when preparing burden harmful element carried out effective control, makes its content can satisfy the requirement of steel-smelting technology standard.
Further specify the present invention below by embodiment.
Embodiment
According to target composition is prepared burden with the nickel and the copper that reclaim, and controls the content of harmful element wherein by chemical analysis;
With above-mentioned nickel and the copper of induction furnace fusing, until its fine melt;
Add ferrosilicon, make the content of Si meet the requirement of target composition, when adding ferrosilicon with 4: 1 lime and fluorite slag making, with removal impurity;
The Chemical Composition of stirring, analysis and accurate adjustment alloy treats that alloy ingredient comes out of the stove after qualified;
After treating the cooling of above-mentioned alloy, it is broken into≤granularity of 50mm with iron hammer.
The composition of above-mentioned alloy is (weight %):
Ni:39%, Cu:40%, Si:9.1%, Pb:0.16%, Zn:0.12%, Sn:0.36%, C:0.08%, P:0.02%, S:0.035%, Fe: surplus.
Above-mentioned alloy is used for the alloying of pipe line steel, and this alloy adds with automatic feeding device.The pipeline molten steel that carries out alloying with this alloy meets the technical specifications of pipe line steel fully.
Claims (2)
1, a kind of nickel-copper-silicon alloy that is used for steelmaking alloy, it contains (weight %):
Ni：35～46％，Cu：35～46％，Si：8～20％。
2, the nickel-copper-silicon alloy that is used for steelmaking alloy as claimed in claim 1, it also contains (weight %): C≤0.10%, P≤0.05%, S≤0.04%, Sn≤0.5%, Pb≤0.3%, the Fe of Zn≤0.3% and surplus.
