Abstract
The invention discloses a nickel-copper alloy. The nickel-copper alloy comprises the following components in percent by weight: 34-37% of Ni, 49-53% of Cu, 6-9% of Si, 0-0.3% of C, 0-0.1% of P, 0-0.2% of S and the balance of Fe. The particle size of the alloy is 10-50 mm and the melting point is 1200-1300 DEG C. The nickel-copper alloy has low melting point, good diffusion performance in molten steel, deoxidation effect and good technological practicability, and is easy to crush.
Description
Technical field
The invention belongs to metallurgical technology field, be specifically related to a kind of make a match corronel of usefulness such as the plain addition agent of gold dollar of steel-making that is applicable to.
Background technology
Along with the development of society, every profession and trade comprises that to high temperature steel, weathering steel and steel alloy freight container plate, sheet material steel and band steel etc. get demand and day by day obviously increase.Alloy of the present invention then is a novel alloy addition of smelting above-mentioned steel grade.Because copper and mickel all has very strong toughness, hand breaking is difficulty very.Existing Alloying Treatment technology all is after electrolytic copper and electrolytic nickel are cut into piece, by high hopper adding molten steel, and makes the stokehold Alloying Treatment.Above technology has some deficiency at least: the one, make the alloy additive with electrolytic copper and electrolytic nickel, and wasted electric energy and auxiliary material in electrolytic copper and the electrolytic nickel production process, will promote the production cost of steel-making enterprise; The 2nd, because single nickel element fusing point is high, the diffustivity that gets 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; Three through caked electrolytic copper of cutting and electrolysis nickel block, must in two high hoppers, store respectively, and will have two covering devices to control respectively, and not only the stokehold support equipment is complicated for this, and operation is also cumbersome.And the present invention just can fundamentally overcome the deficiency of above-mentioned prior art.
Technical scheme
Technical problem to be solved by this invention provides a kind of novel alloy addition corronel.This alloy addition has low melting point, high diffusibility ability, has both deoxidation effect, is easy to fragmentation, makes things convenient for premium propertiess such as flushing and casting.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is following:
Corronel of the present invention comprises following component in percentage by weight:
Ni 34-37％；
Cu 49-53％；
Si 6～9％；
C 0～0.3％；
P 0～0.1％；
S 0～0.2％；
The Fe surplus;
Above-mentioned alloy granularity is 10-50mm, and fusing point is 1200-1300 ℃.
Beneficial effect: corronel of the present invention, its tool fusing point low (1200-1300 ℃), the diffusion in molten steel is good; Have both deoxidation effect; Be easy to fragmentation, the technology practicality is good.
Embodiment
According to following embodiment, can understand the present invention better.Yet, those skilled in the art will readily understand that the described content of embodiment only is used to illustrate the present invention, and the present invention that should also can not limit in claims to be described in detail.
Embodiment 1:
With 0.5t middle frequency furnace and every batch of total throwing amount is that 500kg is an example.
1, preparation of the present invention is subsequent use by following weight batching earlier:
(1) copper 225kg;
(2) nickel 75kg;
(3) 75 ferrosilicon 90kg;
(4) steel scrap 110kg.
2, step of preparation process of the present invention is following:
(1) adds steel scrap intensification fusing;
(2) add the ferrosilicon fusing;
(3) add the nickel fusing;
(4) add copper material and treat that it melts the back fully and stirs slagging-off;
(5) ingot bar of coming out of the stove;
(6) broken pack (particle diameter 10～50mm).
3, the check of the corronel that obtains through above-mentioned prepared by above-mentioned batching requires as follows:
(1) quality inspection of corronel and examination should meet the regulation of GB/T3650;
(2) nickel content is measured by the regulation of GB/T223.23-1994;
(3) copper content is measured by the regulation of GB/T223.18-1994;
(4) silicone content is measured by the regulation of GB/T223.60-1997;
(5) other elements are measured by GB5686.
Through the check, final finished chemical ingredients (weight percentage) as follows:
Ni 35％；
Cu 50％；
Si 8％；
C 0.2％；
P 0.1％；
S 0.1％；
The Fe surplus.
Above-mentioned alloy granularity is 10-50mm, and fusing point is 1260 ℃.
Test Example: the present invention is very convenient with the adz-eye hammer hand breaking; On probation showing adopted the artificial directly addition method of ladle through steel mill, and be easy and simple to handle.
Claims (1)
1. corronel is characterized in that it comprises following component in percentage by weight:
