By using a surfacing welding layer of the invention, the vanadium-reinforced wear-resistant submerged-arc surfacing flux-cored welding wire has the characteristics of uniform rigidity distribution, high wearing resistance and the like, and has good welding process performance.
Description
Technical field
The present invention relates to a kind of vanadium-reinforced wear-resistant submerged-arc surfacing flux-cored welding wire, belong to technical field of welding materials.
Background technology
Flux-cored wire is that alloying element (powder medicine core) is wrapped in sheetmetal the flux-cored wire that forms through being drawn into different-diameter.
Flux-cored wire forms the alloy solder layer with the property such as wear-resistant, corrosion-resistant and high temperature resistant after welding fusing.Flux-cored wire submerged-arc welding occupies an important position in reparation and composite manufacturing, is widely used in the compound position of the mechanical structured members such as high wear resistance of mechanical engineering structure.
The wear-resisting welding wire with flux core that built-up welding is at present repaired generally all contains the alloying elements such as carbon, chromium, silicon, manganese, seldom or hardly contains carbide.
It is generally acknowledged, reinforcing material surface strength and the effective way of improving wearability are to provide case hardness and the obdurability of material, and comparatively desirable layer institutional framework is the particle of equally distributed high-melting-point on tough and tensile, continuous matrix, high rigidity, good stability.The wearability of built-up welding layer is mainly decided by kind, distribution and the Area Ratio of carbide.Contained chromium in wear-resisting powder medicine core forms double carbide (Cr, Fe) with carbon and iron in weld deposit process
7C
3The hexagonal prism structure, its case hardness is HV1200～1800, the hardness ratio front surface of side is slightly low.This shows, the existing flux-cored wire of repairing for built-up welding far can not satisfy the roll of steel plant, the demand that the composite manufacturing of the coal-grinding roller of firepower electrical plant and engineering excavation machinery etc. and maintenance are reproduced etc.
Summary of the invention
The present invention is intended in powder medicine core, by adding v element, and vanadium in the built-up welding molten pool metal with the preferential combination of carbon, form the core of the non-spontaneous nucleation of vanadium carbide, and remarkable crystal grain thinning, and because vanadium carbide can separately exist in hardfacing alloy, play the effect of wear-resisting particle, wearability is further improved, and a kind of vanadium-reinforced wear-resistant submerged-arc surfacing flux-cored welding wire is provided.
The present invention realizes that the technical scheme of its purpose is:
A kind of vanadium-reinforced wear-resistant submerged-arc surfacing flux-cored welding wire comprises the mild steel cored solder wire and is located at the interior powder medicine core of described cored solder wire; The component of described powder medicine core is: high carbon ferro-chrome, vanadium iron, deoxidier and iron powder; The filling rate of described powder medicine core in described cored solder wire is characterized in that in 30～50% scopes:
The weight percentage of described each component of powder medicine core is (%):
High carbon ferro-chrome 30～55;
Vanadium iron 8～20;
Iron powder 25～55;
In 2 kinds of metallic elements of deoxidier silicon and manganese a kind or 2 kind 3～8.
The Main Function of each component is in above-mentioned drug core component:
High carbon ferro-chrome: its composition is 62.0～72.0%Cr ,≤6.0%C, and remaining is Fe.By its transition alloy elements in the hardfacing alloy.
Vanadium iron: its composition is 35.0～50.0%V, and remaining is Fe.Preferentially be combined with carbon in the built-up welding layer by it and form vanadium carbide hard, wear-resistant phase.
Deoxidier: be ferrosilicon or ferromanganese or ferrosilicon and ferromanganese.The ferrosilicon composition is 40.0～47.0%Si, and remaining is Fe; The ferromanganese composition is 75.0～85.0%Mn, and remaining is Fe.By the deoxidation of described deoxidier, increase intensity and the hardness of overlay cladding.
Iron powder: replenish alloying element to hardfacing alloy.
The filling rate of above-mentioned powder medicine core in cored solder wire can according to actual operation requirements and operating mode, be adjusted between 30%～50%.
Describe and to understand by above given technical scheme and the effect of each component of powder medicine core, the present invention is owing to adopting this carbide of vanadium, in built-up welding high temperature molten bath carbon preferential with vanadium reaction generation VC hard phase, and can even dispersion be distributed in hardfacing alloy, thereby when crystal grain thinning improves obdurability, improve the hardness of overlay cladding, strengthened anti-wear performance, realized purpose of the present invention.
In technique scheme, the present invention advocates that described mild steel cored solder wire is the H08A steelwork, or the H10 steelwork.But be not limited to this.Result of the test shows phosphorus content at the mild steel product below 0.2%, all can be used for preparing cored solder wire of the present invention.
In technique scheme, described deoxidier is a kind or 2 kinds in silicon and 2 kinds of metallic elements of manganese.Silicon and manganese are all that wherein the deoxidizing capacity of silicon is higher than manganese than the strong deoxidier lower than aluminium.If adopt the silicomanganese combined deoxidation, its deoxidation effect is more desirable.For this reason, the present invention is recommended.Here should be noted that SiO
2The deslagging situation of-MnO product in hardfacing alloy.
After technique scheme is implemented, its result on trial shows: flux-cored wire welding technological properties of the present invention is good, the overlay cladding case hardness is evenly distributed, average hardness is in HRC42～65 scopes, wearability is 10-30 times of Q235 carbon steel, and have the strong and alloying uniformity coefficient advantages of higher of anti-pore ability, realized original intention of the present invention.
