1.Dab tsi yog cov hauv paus ntsiab lus ntawm kev kho cov corrugated zoo li txias -rolled coils? Cov tswv yim tseem ceeb yog dab tsi?
Lub hauv paus ntsiab lus ntawm strip straightening yog kom lengthen qhov "luv" feem ntawm lub sawb dav los yog luv luv "ntev" feem, thaum kawg ua rau qhov ntev ntawm tag nrho cov seem ntau uniform thiab tshem tawm cov kev ntxhov siab nyob rau hauv. Raws li txoj cai no, muaj peb lub tswv yim tseem ceeb:
Lub tswv yim 1: Roll Gap Control (Kho Thaum Lub Sijhawm Rolling): Thaum lub sijhawm dov, qhov sib txawv ntawm qhov sib txawv yog hloov los ntawm kev kho cov qib ntawm dabtsi yog khoov (khoov rolls), txoj hauj lwm ntawm tus ntoo khaub lig-sectional txav (CVC), lossis inclination ntawm cov yob. Qhov no tso cai rau qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov profile ntawm cov khoom tuaj, yog li tswj qhov sib xws ntawm qhov ncab ntawm qhov chaw.
Lub tswv yim 2: Tom ntej Leveling / Rework (Me me Deformation Straightening): Rau dov steel coils, ib theem zeb yog siv los thov me me deformation dov. Los ntawm kev kho cov dov quab yuam thiab dabtsi yog khoov yob quab yuam, cov duab me me yog txhim kho.
Lub tswv yim 3: Stretch bending straightening (ncaj nrog loj deformation): Rau steel coils nrog loj zoo tsis xws luag, ib tug tshwj xeeb stretch bending straightening tshuab (stretch straightening tshuab) yog siv. Nyob rau hauv kev sib koom ua ke ntawm nro thiab rov khoov, tag nrho qhov ntev ntawm cov sawb hlau yog yas txuas ntxiv, yuam kom ncab qhov "luv" ntu, yog li tau txais kev ncaj ncaj.
2.Yuav ua li cas kho ntau hom nthwv dej hauv online thaum lub caij txias dov?
Rau ib qho - ib sab ntug nthwv dej (linear wavy qauv): Kev kho yog ua tiav los ntawm tilting cov yob. Qhov no yuav ua rau me ntsis nce siab ntawm ib kawg ntawm yob thiab txo nws ntawm lwm yam kom them rau qhov sib txawv ntawm elongation ntawm ob sab ntawm lub sawb.
Rau ob -sab nthwv dej lossis nruab nrab nthwv dej (cov qauv wavy thib ob): Kev kho yog ua tiav los ntawm kev khoov yob thiab CVC (txuas ntxiv mus hloov pauv tau) yob txav. Ob chav -sided nthwv dej qhia ntau tshaj elongation nyob rau hauv nruab nrab ntawm lub strip, yuav tsum tau txo nyob rau hauv lub zoo dabtsi yog khoov yob quab yuam los yog ib tug nce nyob rau hauv qhov tsis zoo dabtsi yog khoov yob quab yuam; nruab nrab nthwv dej, hloov pauv, yuav tsum muaj kev nce ntxiv hauv qhov zoo bending yob quab yuam. CVC yob txav tsis tu ncua hloov cov yob yas kom haum raws li qhov xav tau sib txawv.
Rau peb lub hlis twg- nthwv dej lossis cov nthwv dej sib xyaw (siab dua- xaj cov qauv wavy): Cov qauv no yog qhov nyuaj dua thiab nyuaj rau kev tshem tawm tag nrho siv cov txheej txheem ib txwm siv, yuav tsum tau siv segmented yob txias. Los ntawm hauv zos txau cov dej txias rau cov yob, qhov thermal expansion ntawm thaj chaw ntawd tau hloov pauv, yog li zoo - kho qhov yob qhov sib txawv thiab ua tiav kev tswj xyuas meej ntawm cov kab hauv zos.
3.Can steel coil nrog cov wavy uas twb muaj lawm yuav kho siv lub tshuab leveling? Yuav ua li cas yuav ua tau?
Yog, tab sis nws yog tsim nyog rau me ntsis, uniform waviness. Handan Iron thiab Steel Group (Handan Steel) tau muaj kev ua haujlwm zoo dua: lawv siv lub tshuab txias dov theem zeb los ua haujlwm cov phaj corrugated.
Kev tswj qhov tseem ceeb: Lub hauv paus tseem ceeb ntawm kev ua haujlwm rov ua haujlwm yog tswj elongation thiab dov quab yuam. Kev siv lub zog dov tsis tu ncua ua ke nrog kev ntub dej tuaj yeem txhim kho lub phaj zoo. Handan Steel qhov kev paub dhau los qhia tau hais tias los ntawm kev txhim kho cov txheej txheem, thawj - qib tawm los ntawm cov khoom siv rov ua dua tshiab tau maj mam nce los ntawm 20% mus rau 50%, txo qis cov khoom lag luam los ntawm waviness.
Kev txwv: Qhov txo qis hauv qib qis heev (feem ntau<3%), mainly improving mechanical properties and minor plate shape defects. For severe, complex waviness (such as warping or oblique waviness), leveling is difficult to completely eliminate.
4.Dab tsi yog txoj kev kho kom zoo tshaj plaws rau qhov tsis xws luag los yog nyuaj?
Txoj kev zoo tshaj plaws yog stretch bending straightening (stretch straightening). Nws tuaj yeem tshem tawm tsis tau tsuas yog ib qho ntug thiab qhov nruab nrab waviness, tab sis kuj muaj peb - qhov tsis xws luag xws li flaring thiab sickle khoov.
Lub hauv paus ntsiab lus ua haujlwm: Lub tshuab ncab ncab muaj ntau yam kev khoov thiab kev sib tw ncaj nraim, siv qhov nro loj (kwv yees li 1/3 txog 1/2 ntawm cov khoom siv lub zog tawm los) rau lub sawb. Nyob rau hauv qhov nro no, lub sawb rov khoov duav, rov faib nws cov kev ntxhov siab sab hauv thiab ncab qhov ntev tsis txaus kom phim qhov ntev dua, yog li ua tiav qhov ncaj ncaj.
Cov txiaj ntsig zoo heev: Tom qab kev txhim kho thiab siv lub tshuab ncab ncaj, Taigang lub phaj ncaj tau txhim kho los ntawm 15 I-units mus rau 4 I-units, txhim kho phaj zoo zoo.
Kev Siv Tshuab Tshwj Xeeb: Rau cov phaj tuab lossis cov ntu tshwj xeeb uas tsis tuaj yeem siv siab, muaj cov tshuab ncaj nraim. Piv txwv li, lub tshuab straightening los ntawm German tuam txhab KELER muaj ib tug straightening roller bending muaj nuj nqi, tso cai rau lub straightening rollers bulge nyob rau hauv nruab nrab los yog ntawm ob sab, tshwj xeeb stretching tej thaj chaw ntawm cov khoom kom meej tshem tawm ntug los yog nruab nrab waviness.
5.Raws li tus neeg siv qis qis, yuav ua li cas kho tau yog tias qhov txias -rolled coils koj yuav yog wavy?
Slight Wavy Patterns - Kho Cov Txheej Txheem Stamping: Cov qauv me me tuaj yeem ua "flattened" thaum lub sij hawm tsim cov txheej txheem los ntawm kev ntxiv cov hlaws dai thiab kho qhov tsis muaj zog tuav.
Nruab Nrab Wavy Patterns - Siv lub tshuab Precision Leveling: Ntxiv cov txheej txheem precision (flattening) ua ntej uncoiling lossis txiav. Qhov no yog txoj kev ncaj ncees thiab ua tau zoo tshaj plaws. Los ntawm kev kho qhov ntxig thiab txo qis ntawm lub tshuab leveling, feem ntau wavy deformation tuaj yeem tshem tawm tau zoo, muab cov ntawv tiaj tus rau tom qab stamping.
Cov Qauv Wavy hnyav - Rov qab los yog thov: Yog tias tus qauv wavy hnyav heev (xws li ua tau nyuaj - los - tshem tawm "tuag creases" los yog warping loj), qhov zoo tib yam tsis tuaj yeem daws qhov teeb meem, txhais tau tias cov khoom raug muab pov tseg. Hauv qhov no, qhov kev tsis pom zoo yuav tsum raug tsa nrog tus neeg xa khoom kom rov qab los yog thov.
