Description
Technical field
The invention belongs to the cored wire technology fields that purified steel process uses, and in particular to a kind of vanadium nitrogen aluminium alloy cored
Line.
Background technology
Alloy of vanadium nitride is a kind of novel alloy additive, can substitute production of the vanadium iron for micro alloyed steel.Nitridation
Vanadium alloy makes an addition in steel the comprehensive mechanical performances such as intensity, toughness, ductility and the thermal fatigue resistance that can improve steel, and has steel
There is good solderability.In the case where reaching same intensity, addition vanadium nitride saves vanadium addition 30%-40%, thereby reduces into
This.Alloy of vanadium nitride can be used for structural steel, tool steel, pipe line steel, in reinforcing bar and cast iron.It is low that alloy of vanadium nitride is applied to high intensity
Effective vanadium, nitrogen microalloying can be carried out at the same time in steel alloy, promotes the precipitation of carbon, vanadium, nitrogen compound in steel, more effectively sends out
Wave sedimentation reinforcing and Grain refinement.
It is relatively low due to adding in the rate of recovery in molten steel with block-shape morphology directly by alloy of vanadium nitride, it leads in the prior art
If molten steel vanadium, nitrogen alloying are realized by the method that core-spun yarn is fed into molten steel.This method is block or spherical nitridation
Vanadium alloy is crushed with physical method, then packs into core-spun yarn with iron sheet or sheetmetal, and alloy of vanadium nitride forms the sandwich layer of core-spun yarn, iron
Skin or sheetmetal form the crust of core-spun yarn；Then above-mentioned core-spun yarn by Yarn feeding device is fed in the molten steel in ladle, makes steel
Liquid vanadium, nitrogen alloying.This kind of method vanadium, the nitrogen alloying element rate of recovery are higher, and vanadium recovery exists in 88%-95%, nitrogen recovery
70%-90%.But this kind of method has the following disadvantages：Vanadium recovery is still relatively low, the fluctuating range of vanadium recovery and nitrogen recovery
It is larger, influence the stability of product quality；When the mobility of slag is poor, core-spun yarn is subject to slag during molten steel is fed
Drag effect it is larger, often occur broken string or card line.It is used in addition, Chinese patent 200610020447.0 discloses one kind
Realize molten steel vanadium, the core-spun yarn of nitrogen alloying, which includes steel crust and the sandwich layer made of alloy of vanadium nitride.The bag
Cored wire in actual use, is also present with the above problem.
The content of the invention
The technical problem to be solved by the present invention is to provide it is a kind of improve vanadium recovery be used to implement molten steel vanadium, nitrogen and aluminium
The vanadium nitrogen aluminium alloy core-spun yarn of alloying.
The present invention is solves to adopt the following technical scheme that solve above-mentioned technical problem, a kind of vanadium nitrogen aluminium alloy core-spun yarn,
The vanadium nitrogen aluminium alloy core-spun yarn is made of the sandwich layer of steel band wrapper layer and package in the inner, it is characterised in that the sandwich layer is grain size
Vanadium nitrogen Al alloy powder less than 2mm, the vanadium nitrogen Al alloy powder are made of the element that following weight percent matches：
V 50%-60%；
N 3%；
Fe≤0.3%；
Si≤0.3%；
C≤0.15%；
O≤0.2%；
Surplus is Al.
Further preferably, the vanadium nitrogen Al alloy powder is made of the element that following weight percent matches：
V 56%；
N 3%；
Fe 0.3%；
Si 0.3%；

O 0.2%；
Al 40.05%。
The vanadium nitrogen aluminium alloy core-spun yarn of the present invention is when refining some specific alloys of titanium alloy, high-temperature alloy base as member
Plain additive enhances anticorrosive, high temperature resistance, and effectively improves intensity.
Specific embodiment
The above of the present invention is described in further details by the following examples, but this should not be interpreted as to this
The scope for inventing above-mentioned theme is only limitted to following embodiment, and all technologies realized based on the above of the present invention belong to this hair
Bright scope.
