Description
Technical field
The utility model is related to a kind of sinking roller of anti-zinc erosion.
Background technology
Sinking roller is the critical component of hot-galvanizing equipment.Traditional sinking roller is main based on ferrous materials, but due to iron
The low melting point Fe5Zn21 and FeZn13 intermetallic compound (being commonly called as cadmia) of porosity and looseness can be formed in zinc liquid and zinc is floated to
In liquid, its resist melt liquid zinc corrosion is very poor, therefore service life is shorter, need to often change, and has a strong impact on normally entering for production
OK.
Sinking roller is one of visual plant on hot galvanizing line, needs for sinking roller to be integrally immersed in fusing in production
In zinc liquid, and rotated with the dragging of galvanized sheet.In galvanizing process, aluminium, iron, zinc alloy element can be attached to roll surface
On, form uneven dross, i.e. dry slag；In addition, zinc liquid often can be deposited in the middle of roller in roller operation process, do not flow
Dynamic zinc liquid comes in contact with roller, similarly produces zinc-iron alloy to be attached to roller surfaces.Above-mentioned phenomenon with the time passage
And aggravate, strip is produced arch bag, projection, so as to have a strong impact on the product quality of galvanized sheet.For drawbacks described above, this area skill
Art personnel need the sinking roller for providing a kind of anti-zinc erosion badly, prevent sinking roller from being corroded by liquid Zn, improve the quality of sinking roller,
Extend the service life of sinking roller.
Utility model content
The purpose of this utility model is to provide a kind of sinking roller of anti-zinc erosion, prevents sinking roller from being corroded by liquid Zn,
The quality of sinking roller is improved, extends the service life of sinking roller.
To achieve the above object, there is provided following technical scheme：A kind of sinking roller of anti-zinc erosion, including roller and be welded and fixed
In the roll shaft at two ends, the roller includes cylindrical base, and described matrix surface is provided with the V-shaped structure at least one cross section
Helicla flute, described matrix surface spraying Fe-Al intermetallic compounds layers, the Fe-Al intermetallic compounds layers surface is coated with
Protective coating, the material of the protective coating is ZrB2In mixed with graphite ceramic composite.
Preferably, the Fe-Al intermetallic compounds layers are FeAl3、Fe2Al3, FeAl and Fe3One kind or number in Al
Kind.
Preferably, the thickness of the Fe-Al intermetallic compounds layers is 50~80 μm.
Preferably, the thickness of the protective coating is 20~40 μm.
Preferably, described matrix surface is provided with the helicla flute of the V-shaped structure of two sliver transvers sections.
Preferably, two helicla flutes are uniformly distributed on described matrix surface.
Preferably, the roller is solid construction.
The utility model provides a kind of having the beneficial effect that for sinking roller of anti-zinc erosion：The utility model makes sinking roller surface
Dry slag delivers to the end of sinking roller along the hand of spiral of helicla flute, it is to avoid form uneven dross on the surface of sinking roller, no
Product quality is improve only, the replacing number of times of sinking roller is greatly reduced, raw material has been saved；While Fe-Al intermetallic compounds
Layer has good anti-zinc erosion ability, because the fusing point of Fe-Al intermetallic compounds layers is less than 1200 degree, is easier to use thermal jet
The method of painting forms coating, and liquid Zn can be also resisted in the state of other sealing materials are not used；Additionally, protective coating has
Case hardness, good abrasion resistance properties, the liquid zinc corrosion of resistance to melting performance, heatproof oxidation performance higher, substantially increases sinking
The anti-zinc erosion ability of roller, improves the quality of sinking roller, extends the life-span of sinking roller.
