Abstract
The invention discloses a kind of flux-cored wire, be made up of crust and medicine core, crust is mild steel, and medicine core is the 14~22% of the flux-cored wire quality, composition that medicine core contains and its account for flux-cored wire gross mass percentage it is as follows：TiO21.6~5.0%, SiO20.4~1%, Mn1.0~3.0%, Si0.2~0.4%, Al2O30.10~0.20%, CaCO30.10~0.20%, CaF20.21~0.41%, Cr0.6~1.4%, Mo0.8~2.0%, Ni3~6%, V0.05~0.10%, Re0.01~0.02%, Al0.15~0.35%, Fe surplus.Flux-cored wire provided by the invention has high intensity, toughness, good crack resistance.
Description
Technical field
The present invention relates to flux-cored wire technical field.A kind of it is more particularly related to flux-cored wire.
Background technology
Flux-cored wire is also referred to as flux cored wire or, can be by adjusting the alloying component species and ratio of medicinal powder, easily
The welding material of various different purposes (wear-resisting, high-strength, heat-resisting, anti-corrosion, low temperature resistant etc.) is designed on ground, because its alloying component
Adjustment that can be flexible, can not smelt and roll so many kinds of flux-cored wire are solid welding wires.Medicine core weldering simultaneously
The characteristics of silk is due to product structure, welding technological properties and welding efficiency compare solid core welding wire, and stick electrode is advantageously.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantages of at least will be described later.
In order to realize according to object of the present invention and further advantage, there is provided a kind of flux-cored wire, by crust and fill out
Fill and formed in the outer intracutaneous medicine core, it is characterised in that the crust is mild steel, and the medicine core quality is welded for the medicine core
The 14~22% of yarn quality, composition that the medicine core contains and its account for the flux-cored wire gross mass percentage it is as follows：
TiO21.6~5.0%, SiO20.4~1%, Mn 1.0~3.0%, Si 0.2~0.4%, Al2O30.10~
0.20%, CaCO30.10~0.20%, CaF20.21~0.41%, Cr 0.6~1.4%, Mo 0.8~2.0%, Ni 3~
6%, V 0.05~0.10%, Re 0.01~0.02%, Al 0.15~0.35%, Fe surplus.
Preferably, ZrO is also contained for described flux-cored wire, the medicine core2, account for the hundred of the flux-cored wire gross mass
Divide than being 0.1~0.5%.
The present invention comprises at least following beneficial effect：Flux-cored wire high intensity provided by the invention, high tenacity and good
Cracking resistance.
Further advantage, target and the feature of the present invention embodies part by following explanation, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
Embodiment 1
A kind of flux-cored wire, by crust and it is filled in the outer intracutaneous medicine core and forms, the crust is mild steel, described
Medicine core quality is the 14~22% of the flux-cored wire quality, the composition and its account for the total matter of the flux-cored wire that the medicine core contains
The percentage of amount is as follows：
TiO21.6~5.0%, SiO20.4~1%, Mn 1.0~3.0%, Si 0.2~0.4%, Al2O30.10~
0.20%, CaCO30.10~0.20%, CaF20.21~0.41%, Cr 0.6~1.4%, Mo 0.8~2.0%, Ni 3~
6%, V 0.05~0.10%, Re 0.01~0.02%, Al 0.15~0.35%, Fe surplus.
The medicine core also contains ZrO2, the percentage for accounting for the flux-cored wire gross mass is 0.1~0.5%.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
In specific details and shown here as the embodiment with description.
