1.Dab tsi yog qhov dav thiab ntev kam rau ua?
Dav kam rau ua: Feem ntau 0 txog +5 hli (zoo kam rau ua, tsis muaj qhov tsis zoo rau kev tso cai, los xyuas kom meej qhov kev pab cuam ntawm cheeb tsam xav tau). Rau cov kev xav tau siab dua, kev kam rau siab ntawm 0 txog +2 hli lossis ± 1 hli tuaj yeem ua tau.
Ntev Ntev: Feem ntau 0 txog +5 mm. Rau siab precision yuav tsum, kam rau ua ntawm 0 txog +3 hli los yog ± 1.5 hli.
2.Dab tsi yog qhov yuav tsum tau ua rau cov duab raug?
Camber: Hais txog qhov curvature ntawm sab ntug.
Ib txwm precision: Tsawg dua los yog sib npaug rau 3mm ib 2000mm (ie, 1.5mm / m).
High precision: Tsawg dua los yog sib npaug rau 1.5mm ib 2000mm (ie, 0.75mm / m).
Rau qee qhov siab - cov ntawv thov kawg (xws li cov khoom siv hauv tsev), qhov yuav tsum tau nruj dua 0.5mm / m.
Roughness (wavy): Hais txog qhov undulation ntawm daim ntawv nto nyob rau hauv kab rov tav dav hlau.
Qhov kev qhia tshwj xeeb no yog nyob ntawm cov khoom siv raw khoom thiab kev ua haujlwm ntawm lub tshuab flattening. Qhov yuav tsum tau muaj tsawg dua los yog sib npaug li 5 hli ib 'meter'. High- qhov yuav tsum tau ua kom muaj tseeb yuav xav tau tsawg dua lossis sib npaug li 3 hli lossis txawm tias tsawg dua lossis sib npaug li 1.5 hli.
Diagonal deviation: Rau cov nplooj ntawv duab plaub, qhov sib txawv ntawm qhov ntev ntawm ob kab pheeb ces kaum.
Cov kev cai dav dav: Tsawg dua lossis sib npaug li 3 hli rau qhov ntev Tsawg dua lossis sib npaug li 4m; Tsawg dua lossis sib npaug li 5 hli rau qhov ntev> 4m. Qhov kev qhia tshwj xeeb no cuam tshuam qhov tseeb ntawm kev sib dhos thiab vuam tom ntej.
3.Dab tsi yog qhov sib txawv ntawm qhov yuav tsum tau muaj tseeb hauv ntau qhov kev thov?
Kev siv dav dav (xws li cov pa cua thiab cov khoom siv sib xyaw):
Lub teb chaws tus qauv "Ordinary Precision (PT.A)" yog txaus, thiab cov kev cai rau camber thiab unevenness yog kuj so.
Cov khoom siv hauv tsev (xws li cua txias, tshuab ntxhua khaub ncaws, thiab tub yees):
Yuav tsum tau ua kom muaj tseeb dua, feem ntau ua tau raws li lub teb chaws tus qauv "Higher Precision (PT.B)" lossis txawm tias cov tuam txhab nruj dua.
Cov txheej txheem nruj heev uas yuav tsum muaj nyob, nrog camber feem ntau yuav tsum yog <1mm / m thiab qhov tsis sib xws yog <3mm / m kom ntseeg tau tias du thiab zoo nkauj pleasing stamping thiab sib dhos.
Lub tsev qhov rooj thiab qhov rais, hniav panels:
High thickness thiab dav precision yuav tsum tau los xyuas kom meej installation thiab sealing. Cov duab zoo heev yog qhov tseem ceeb kom tsis txhob cuam tshuam qhov tsos.
4.Dab tsi yog yam tseem ceeb cuam tshuam rau Kaiping qhov tseeb?
Raw khoom zoo: Lub thickness uniformity thiab zoo (wrinkle thiab camber) ntawm galvanized raw coil yog qhov tseem ceeb.
Kaiping khoom zoo:
Number of leveling rollers (qhov ntau rollers, qhov zoo dua cov nyhuv leveling).
Cov cuab yeej rigidity, stability, thiab automation tswj theem.
Daim ntawv thov kev soj ntsuam hauv online xws li thickness gauges thiab laser velocimetry.
Kev tswj cov txheej txheem ntau lawm:
Teem uncoiling nro.
Kho lub leveling roller siab.
Qhov sib txawv thiab sharpness ntawm shear hniav.
5.Dab tsi yog tus qauv precision rau flattening galvanized coils?
Thickness kam rau ua: Xa mus rau GB / T 708, tus qauv qib: ± 0.05mm txog ± 0.13mm (siv 1.0-2.0mm ua piv txwv), halved rau qib siab dua.
Dav/Length kam rau ua: Feem ntau 0 txog +5mm, nrog siab -precision kam rau ua ncav cuag 0 txog +2mm.
Camber: Standard qib: Tsawg dua lossis sib npaug li 1.5mm / m, qib siab dua: Tsawg dua lossis sib npaug li 0.75mm / m, nrog cov kev cai nruj dua rau cov khoom siv hauv tsev thiab kev siv tsheb.
Roughness: Feem ntau Tsawg dua lossis sib npaug li 5mm / m, qib siab dua: Tsawg dua lossis sib npaug li 3mm / m.
