Layer is distributed a large amount of fine cracks.During under arms, grinding roller is once by shock loading, and crackle easily extends also
It is linked to be netted, causes overlay cladding spalling failure.Fall block peeling off is the topmost failure mode of this type of grinding roller, will cause
Grinding machine stops production and keeps in repair, and has had a strong impact on its production efficiency and product quality.Therefore, a kind of deposited metal hardness of exploitation
Height, wearability are good, and the production efficiency improving grinding machine is had significantly by the resurfacing welding material with excellent impact resistance
Meaning.
Summary of the invention
It is an object of the invention to provide a kind of chromium-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire, this medicated core
Welding wire uses 98%Ar+2%O2Gas shielded welding, its welding technological properties is excellent, and the hardness of overlay cladding is high
(more than HRC59), wearability is good, it is adaptable to grinding roller, the composite manufacturing by hard surfacing of mill and repair online.
Another object of the present invention is to provide the preparation method of a kind of described flux-cored wire.
For achieving the above object, the present invention is by the following technical solutions:
A kind of chromium-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire, by external carbon steel band and the medicated powder of its parcel
Composition, wherein, medicated powder accounts for the 38.0%-42.0% of welding wire gross weight, the ratio of each component is: high-carbon in this medicated powder

0.3%-0.8%, B 0.02%-0.1%, Fe surplus.
The chromium of the present invention-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire, its phosphorus content is less than high-carbon high-alloy
Cast iron, belongs to high-carbon steel category, reduces the tendency of hardenability of overlay cladding, it is to avoid overlay cladding forms micro-crack；Add simultaneously
Add titanium elements and form granular carbonization titanium, with block chromium carbide complex intensifying overlay cladding.Although the carbon content of overlay cladding
Relatively low, but the existence of granular carbonization titanium improves the hardness of overlay cladding, and reduce its peeling tendency, do not improving
On the premise of overlay cladding phosphorus content, it is ensured that the hardness of overlay cladding reaches more than HRC59, and overlay cladding flawless,
Improve its anti-strip ability, the service life of grinding roller can be extended.
The chromium of the present invention-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire is by carbonization in built-up welding deposited metal
The hardening constituent such as titanium, chromium carbide improves hardness and the wearability of deposited metal.Owing to titanium is active element, welding
Journey easily aoxidizes, causes the titanium elements in medicated powder to be difficult to be transitioned into built-up welding deposited metal, it is therefore desirable to pass through formula
Technology solves this technical barrier, to ensure Ti content in deposited metal.The present invention is by adding silicon in welding wire medicated powder
Calcium alloy, the calcium constituent that in welding process, scaling loss is more active, to reduce the oxidization burning loss of titanium elements, improves the mistake of titanium
Cross coefficient；And the oxidation product of titanium elements (titanium oxide) also can join with the oxidation product (silicon oxide) of element silicon
Close slag making, improve quality of weld seam molding.Additionally, the flux-cored wire of the present invention uses neutral protective gas
(98%Ar+2%O2) welding, the amount of oxidation loss of titanium elements relatively uses oxidizing gas (100%CO2) notable
Reduce；The O of 2% is added in argon2, it is for increasing arc stability, and improves the forming quality of weld seam.
For the production technology of chromium-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire, its external steel band is low
Carbon steel band, in order to ensure the production technology of welding wire, needs the strict technical parameter controlling external steel band.Resisting of steel band
Tensile strength is too low, will cause the deflection of drawing welding wire process not, easy heap silk in production, and welding wire easily reverses, will
Cause electric arc in welding process to rotate with the torsion of welding wire, reduce arc stability, deteriorate quality of weld seam molding.
The tensile strength of steel band is too high, and elongation percentage is too small, will cause drawing welding wire difficulty, fracture of wire easily occurs in drawing process,
Production process is discontinuous, and yield rate is low.The tensile strength of the external carbon steel band that the present invention uses is not less than 270MPa,
Elongation percentage is not less than 40%, raw to realize the high-efficiency and continuous of chromium-titanium intensified high-carbon high-alloy steel abrasion-proof overlaying welding flux-cored wire
Produce.
The preparation method of the flux-cored wire of the present invention is: made by the external steel band of thickness 0.3mm, width 16mm
U-shaped, in U-lag add medicated powder, after U-lag heals up, carry out successively φ 4.32mm, φ 3.51mm, φ 2.87mm,
φ 2.34mm, φ 1.97mm five passage continuous drawing tube reducing, obtain the flux-cored wire that specification is φ 2.0mm.
The flux-cored wire of the present invention, takes into account built-up welding deposition efficiency and the advantage of gas shielded welding, i.e. welding wire has flue dust
Few, splash little, the feature of the gas shielded welding such as flexible operation, and gage of wire specification is relatively big (φ 2.0mm), its
Built-up welding deposition efficiency is significantly higher than the gas protection wire (φ 1.2mm) of regular size.
The invention have the benefit that
The flux-cored wire welding technological properties of the present invention is excellent, and arc stability, spatter are little, quality of weld seam molding
Good, the metallurgical imperfection such as flawless, pore, slag inclusion.
