1.What yog lub hauv paus ntsiab lus ntawm kev tiv tauj nrhiav kev siv thev naus laus zis thiab nws ua haujlwm li cas?
Cov ntaub ntawv deformation yog kis tau los ntawm sensors hauv kev sib cuag nrog cov sawb nto. Cov piv txwv ib txwm yog "kev kho tshuab ntsuas cov menyuam":
Lub hauv paus ntsiab lus: Sawb tsis xwm yeem tau hloov pauv mus ua feeb ntawm cov menyuam theem ntawm cov menyuam. Ib qho kev hloov chaw (xws li lub tshuab hloov pauv sib txawv) mounted ntawm cov menyuam sau lub teeb liab, thiab ib qho algorithm yog siv los laij cov sawb puab kev sib txawv.
Nta: Cov qauv yooj yooj yim thiab tus nqi qis, tab sis raug rau cov roj stains (feem ntau siv nyob rau hauv qis {} ceev} {precision dov cav).
2.Qhov dab tsi yog cov hom nquag ntawm tsis -}}}} Hu tau mus nrhiav tau Technology?
Cov kev kuaj xyuas kho qhov muag muaj xws li kev ntsuas laser scanning thiab CCD cov duab.
Txoj kev ntsuas laser scanning siv ib qho "kev nrhiav network" ntawm ntau cov hlua transmitters thiab txais. Tsis nyob rau hauv lub strip thaiv lossis hloov cov laser ntawm txoj kev hais tawm. Tus tau txais kev hloov teeb liab hloov los laij cov nthwv dej txoj haujlwm thiab amplitude. Lub CCD txoj kev xav siv lub siab- ceev lub yees duab los ntes cov kab npoo thiab tshawb xyuas cov duab uas tau lees paub lus (xws li ntug kev pom).
Nta: Kev Nrhiav Kom Tau Kom Loj (Yoj Qhov Siab Nrhiav tau accur±ောင်း expectiony tuaj yeem ncav cuag ± 0.01 hli) thiab cov lus teb sai (ntsuas zaus tuaj yeem tshaj 1000zz). Nws yog tsim nyog rau high- ceev, siab {{4 4}} precotive colling (xws li ntaub ntawv kho tshuab thiab khoom siv).
Eddy kev sim tam sim no: Siv EDDY tam sim no cuam tshuam ntawm sawb (cov khoom siv coj) thiab cov khoom siv tshawb xyuas. Thaum cov sawb khoov, qhov kev hloov pauv ntawm kev deb ntawm lub coil ua rau eddy kev siv tam sim no hloov. Lub coil voltage teeb liab yog tom qab ntawd siv rau infer sawb puab.
Nta: tsis muaj kev cuam tshuam los ntawm lub teeb lossis roj ntawm sawb saum npoo, nws yog qhov haum rau cov pa hluav taws xob (xws li txias dov nrog siab emulsion siab). Txawm li cas los xij, nws yog qhov tsawg dua rau tsis - Cov ntaub ntawv (xws li coated sawb). Kev sim ua kev ntxhov siab ncaj qha cuam tshuam txog kev ntsuas tus qauv ntawm kev ntsuas kev ntxhov siab sab hauv ntawm cov sawb. (Sawb cov qauv tsis xws luag yog qhov tseem ceeb ntxhov siab sib txawv ntawm cov kab sib txawv ntawm cov sensor, los ntawm kev txhim kho micro sensor, uas yog hloov pauv mus rau cov ntaub ntawv cov ntaub ntawv.
Nta: Nws tuaj yeem cuam tshuam ncaj qha rau cov sawb's "intrinsic tsis xws luag" (zam kev cuam tshuam "cuav" ntawm kev sim sab nrauv). Txawm li cas los xij, lub sensor yog qhov nyuaj rau nruab thiab yog yooj yim cuam tshuam los ntawm kev nro hloov pauv.
3.Qhov yog cov kev faib tawm thiab cov yam ntxwv ntawm yob khoov tshuab li cas?
Kev faib tawm yob, yob dabtsi yog muab faib ua "Nruab Nrab Kev Kho Mob, haum rau kev kho kom zoo dua qub, haum rau rau 6- cov mills siab).
Nta: Cov lus teb ceev (kev kho kom haum siv txiaj ntsig tsis pub dhau 0.5- 1 thib ob) thiab kev ua haujlwm yooj yim. Nws yog tus txheej txheem thev naus laus zis rau cov colling txias colling, tshwj xeeb tshaj yog plaub - High thiab rau-siab Mills.
4.Qhov cov ntawv teev npe ntawm cov menyuam ua haujlwm li cas?
Cov ntawv thov raug suav nrog "Intermediate yob traverse" hauv - high rolling mills. Nruab nrab yob yog feem ntau tsim nrog tapered xaus. Thaum hla kev, cov tapered feem "zam" sawb strawb, txo cov zog yob ntawm ntug thiab li suppressing ntug ripples. Traverse kuj txo cov yob ntug kev hnav (tsis sib xws ntug tuaj yeem exacerbate phaj qauv tsis xws luag).
Ua ke nrog yob dabtsi yog: traviant feem ntau kho cov ntug {}}}}}} Ua ke, ob txoj hau kev tuaj yeem hais txog 80% ntawm cov phaj uas tsis xws luag (xws li ntug ripples, chaw ripples, thiab peb hlis tom qab).
5.Txoj kev tswj hwm yob qaij thiab nruj?
Cov menyuam tilting: kho lub kaum sab xis nruab nrab ntawm cov xim sab sauv thiab cov quag yob ntawm ib qho) kom hloov lub zog dov hla txoj hlua ntawm strip. (Piv txwv li, yog tias ntug yoj ntawm sab laug ntawm sawb, qaij txoj hlua khi kom nqaim lub yob sab laug thiab txo cov ncab ntawm sab laug.)
Nta: Haum rau kev kho "ib qho {{{{0} ated ib yam nkaus yog tsawg dua los yog sib npaug nrog 0.5 degree), thiab nws yuav tsum tau siv ua ke nrog yob dabtsi yog khoov.
Nro tswj: kho cov sawb lub zog dov (rub lub zog ntawm sab pem hauv ntej thiab nram qab qhov kev faib tawm) Txhawm rau hloov pauv kev ntxhov siab hauv sawb (Tension tuaj yeem "flatten" me vuag). Yog tias muaj me nruab nrab -}}}}}}}}}}}}}}} nrawm tuaj yeem thov cov nro ntawm txoj hlua ntawm cov nthwv dej. Txawm li cas los xij, ntau dhau ntawm cov nro tuaj yeem ua rau kev tawg paj tawg, yog li nws tsuas yog siv los ua kev ntsuas ntxiv (feem ntau yog nrog yob dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog khoov dabtsi yog).
