Description
Technical field
The invention belongs to technical field of welding materials, be specifically related to a kind of abrasion-proof overlaying welding flux-cored wire.
Background technology
Built-up welding is quick process as a kind of economic of material surface modifying, is applied to each more and more widely
During the manufacture of industrial department part is repaired.In order to play the effect of overlay cladding most effectively, it is desirable to the overlaying method of employing has relatively
Little mother metal dilution, higher deposition rate and excellent overlay properties, i.e. high-quality, efficient, the technique for overlaying of low dilution rate.
The hardfacing materials carbon containing commonly used at present and alloying element are higher, mainly by carbon and chromium, titanium, vanadium,
Niobiums etc. form carbide hard particle, improve the hardness of surfacing layer metal, thus improve its anti-wear performance.But this type of welding material
Owing to phosphorus content is high, the most anti-weld crack ability is poor, and toughness is relatively low.Research finds, reinforcing material surface strength and improvement
The effective way of wearability is to provide case hardness and the obdurability of material, and ideal organizational structure is tough and tensile, continuous print
The particle of high-melting-point, high rigidity, good stability it is uniformly distributed on matrix.Existing CO2The letter of gas shielded flux cored wire overlay-operation
Just, low cost, production efficiency high, but generally there is the problem that powder amount is higher.
Summary of the invention
For the problems referred to above, the present invention researchs and develops one, and powder amount is little, crack resistance good, be suitable for anti-greater impact work

In medicated core used by the present invention, each raw material is marketable material, and particle diameter is 100-300 μm, and its action principle is as follows:
Titanium dioxide: containing the TiO more than 98%2, overheated molten drop is had good protective effect, reduces droplet transfer process
Middle evaporation；TiO2Titanate can be combined into FeO and enter slag, reduce iron oxide fumes；Slag making simultaneously, stably welds electricity
Arc, and improve welding technological properties.Anhydrite: arc stabilizer, has the effect of stable electric arc, can increase the viscosity of slag, and it is overheated to protect
Molten drop, reduces powder amount.Cryolite: simultaneously contain Na, Al stabilising arc element, has stabilising arc effect, reduces the expansion in weld seam simultaneously
Dissipate hydrogen content, improve the anti-crack ability of weld seam.Zircon: be mainly used in slag making, improves the removability of slag of slag.Ferrosilicon and manganese
Ferrum: fully deoxidation, desulfurization, restrains the deoxygenation of carbon, it is to avoid CO (carbon monoxide converter) gas produces, and reduces powder amount.Crome metal, titanium
Ferrum, ferro-niobium, chromium nitride: transition alloy elements in weld seam, formation high tenacity matrix+be uniformly distributed abrasion-resistive hard in a large number
Phase.Iron powder: make weld metal increase, improves deposition efficiency.
The present invention has a following positive beneficial effect:
Wear-resisting welding wire with flux core carbon content of the present invention is low, and (carbon containing hardly in the drug core component in welding wire, carbon source is only H08A steel
Carbon in band, the most extremely low, less than 0.08%), anti-weld crack performance is strong, according to GB GB1225-76 method of testing, sends out dirt
Measure and reduce more than 30% than commercially available flux-cored wire, there is good welding technological properties, all-position welding can be carried out, have the highest
Deposition efficiency, weld layer case hardness is evenly distributed, and average hardness can be in the range of HRC40-56, and impact flexibility is high, has
Well anti-wear performance, impact resistance mill performance is 5-10 times of No. 45 steel, is particularly suitable for anti-greater impact effect wear working condition
Lower use.
