Description
Technical field
The invention belongs to technical field of welding materials, and in particular to a kind of abrasion-proof overlaying welding flux-cored wire.
Background technology
A kind of economic and quick process of the built-up welding as material surface modifying, more and more widely applied to each
During the manufacture of industrial department part is repaired.In order to most effectively play the effect of overlay cladding, it is desirable to the overlaying method of use have compared with
Small base material dilution, higher deposition rate and excellent overlay properties, i.e., high-quality, efficient, low dilution rate technique for overlaying.
The hardfacing materials that are commonly used are carbon containing and alloying element is higher, mainly using carbon and chromium, titanium, vanadium,
Niobium etc. forms carbide hard particle, to improve the hardness of surfacing layer metal, so as to improve its wear-resisting property.But such welding material
Since phosphorus content is high, often anti-weld crack ability is poor, and toughness is relatively low.The study found that reinforcing material surface strength and improvement
The effective way of wearability is to provide the case hardness and obdurability of material, and ideal institutional framework is tough and tensile, continuous
The good particle of high-melting-point, high rigidity, stability is uniformly distributed on matrix.Existing CO2The letter of gas shielded flux cored wire overlay-operation
Just it is, at low cost, production efficiency is high, but the problem of generally existing powder amount is higher.
The content of the invention
In view of the above-mentioned problems, the present invention researchs and develops, a kind of powder amount is small, toughness is high, the CO of resistance to 600 DEG C of high temperature wears2
Gas protects weldering abrasion-proof overlaying welding flux-cored wire.
For solution more than technical problem, the invention is realized by the following technical scheme：
A kind of abrasion-proof overlaying welding flux-cored wire, including crust and medicine core, medicine core includes the raw material of following mass percent：Titanium
White powder 5-10%, feldspar 2-8%, ice crystal 1-5%, zircon 2-5%, rare earth silicon 2-8%, ferromanganese 5-10%, crome metal 30-50%, tungsten
Iron 8-20%, surplus are iron powder.
Preferably, the medicine core includes the raw material of following mass percent：Titanium dioxide 5-8%, feldspar 3-6%, ice crystal 3-
4%th, zircon 3-4%, rare earth silicon 4-7%, ferromanganese 6-8%, crome metal 35-42%, ferrotungsten 9-16%, surplus are iron powder.
It is furthermore preferred that the medicine core is made of the raw material of following mass percent：Titanium dioxide 7%, feldspar 5%, ice crystal 3%,
Zircon 4%, rare earth silicon 5%, ferromanganese 7%, crome metal 40%, ferrotungsten 12%, iron powder 17%.
Abrasion-proof overlaying welding flux-cored wire of the present invention is drawn into straight by the uniformly mixed medicine core powder of H08A steel bands package through rolling
Footpath be 1.6-2.4mm flux-cored wires, filling rate（Medicine core accounts for the percentage of flux-cored wire gross weight）For 20-40%.
The content of rare earth of rare earth silicon described above is 30-33wt%, silicone content 30-35wt%.
Each raw material is marketable material in medicine core used in the present invention, and grain size is 100-300 μm, and action principle is as follows：
Titanium dioxide：Contain the TiO more than 98%2, there is good protective effect to the molten drop of overheat, reduce the droplet transfer
It evaporates in the process；TiO2Titanate can be combined into FeO and enters slag, reduces iron oxide fumes；Welding is stablized in slag making simultaneously
Electric arc, and improve welding technological properties.Feldspar：Arc stabilizer plays an important role of to stablize electric arc, can increase the viscosity of slag, protect
Hot melt drop, reduces powder amount.Ice crystal：Simultaneously containing Na, Al stabilising arc element, there is stabilising arc effect, while reduce in weld seam
Diffusible hydrogen content improves the anti-crack ability of weld seam.Zircon：It is mainly used for slag making, improves the removability of slag of slag.Rare earth silicon and
Ferromanganese：Abundant deoxidation, desulfurization, stablize electric arc, restrain the deoxygenation of carbon, CO gas is avoided to generate, and reduce hair dirt
Amount.Rare earth silicon plays an important role of that crystal grain thinning is made, promotes the high hard phase disperse educt of stability simultaneously, hence it is evident that raising toughness and resistance to
High temperature grinds performance.Crome metal, ferrotungsten：The transition alloy elements into weld seam form high tenacity matrix+be largely uniformly distributed height
The good anti-abrasive hard tissue of temperature stability.Iron powder：Increase weld metal, improve deposition efficiency.
The present invention has following positive beneficial effect：
Wear-resisting welding wire with flux core carbon content of the present invention is low（Hardly carbon containing in drug core component in welding wire, carbon source is only
Carbon in H08A steel bands, thus it is extremely low, less than 0.08%）, anti-weld crack performance is strong, according to national standard GB1225-76 test sides
Method, powder amount reduce more than 30% than commercially available flux-cored wire, have good welding technological properties, can carry out all-position welding, have
There is very high deposition efficiency, welding layer case hardness is evenly distributed, and average hardness can be in the range of HRC50~60, impact flexibility
There is height good high temperature resistant to grind performance, and high temperature resistant mill performance is 10-20 times of No. 45 steel, is especially suitable for resistance to 600 DEG C of high temperature mill
It is used under damage operating mode.
