1.Dab tsi yog qhov kev tiv thaiv tseem ceeb tshaj plaws thaum ntim khoom txias -rolled coils?
Tiv thaiv xeb: Txias-cov coils muaj qhov du heev thiab tsis muaj txheej txheej, ua rau lawv tsis tshua muaj xeb. Thaum lub sij hawm ntim, nws yog ib qho tseem ceeb los xyuas kom meej cov hlau kauj yog nruj nreem qhwv nrog xeb- ntawv pov thawj thiab cov khoom tsis muaj dej, tsim kom muaj qhov chaw kaw ib ntus. Cov ua tau -nyob rau hauv vapor-theem xeb-cov ntaub ntawv tiv thaiv tawm xeb-cov pa tiv thaiv uas ua raws li qhov chaw, tiv thaiv oxidation.
Tiv thaiv kev puas tsuaj rau cov khoom siv hlau: steel coils hnyav heev; txawm tias qhov sib txawv me ntsis tuaj yeem ua rau muaj kev sib txhuam ntawm cov khaubncaws sab nraud povtseg, ua rau cov pob dub lossis khawb. Kev ntim khoom yuav tsum xyuas kom meej tias cov coils sab hauv thiab sab nrauv, nrog rau cov coils lawv tus kheej, tsis txhob xoob lossis hloov pauv thaum nqa thiab thauj.
2.Vim li cas thiaj yuav tsum tau siv lub kaum tiv thaiv thaum ntim txias - dov coils? Lawv txoj haujlwm yog dab tsi?
Kev Tiv Thaiv Hlau Straps: Ntim cov hlua steel (bundles) ua kom muaj kev nruj nruj thaum nruj. Yog tsis muaj lub kaum tiv thaiv, cov npoo ntse ntawm cov hlua hlau tuaj yeem kos ncaj qha rau hauv lossis ua rau cov npoo ntawm cov hlau kauj, ua rau burrs lossis indentations. Cov khoom puas no feem ntau yuav tsum tau txo qis lossis tshem tawm.
Cov hlua tiv thaiv: Cov npoo ntawm steel coils yog ntse heev. Thaum lub sij hawm thauj thiab kev vibrations, tsis muaj lub kaum tiv thaiv, txoj hlua khi yuav raug txiav los ntawm cov npoo ntawm lub kauj, ua rau nws tawg thiab ua rau muaj kev nyab xeeb. Corner protectors feem ntau yog txoj cai -angled thiab haum nyob ib ncig ntawm lub ntug sab nrauv ntawm lub steel kauj, cia lub strapping mus hla tus nto ntawm lub kaum protector, tiv thaiv ob lub steel kauj thiab lub strapping nws tus kheej.
3.Dab tsi yog qhov kev txiav txim siab txog tus lej ntawm cov ntawv khi thiab txoj kev (circumferential vs. radial)?
Radial strapping (perpendicular mus rau axis): Qhov no yog txoj kev strapping ntau tshaj plaws, feem ntau yog siv 3-5 straps. Nws ua zoo li ob peb txoj hlua khi kom ruaj ntseg steel kauj, feem ntau tiv thaiv kev hloov pauv ntawm interlayer thiab lub cev qhuav dej thaum dov lossis sab-ntev. Rau cov coils dav dua, cov xov tooj ntawm cov hlua radial yuav tsum tau nce ntxiv.
Circumferential strapping (piav mus rau lub axis, dhau ntawm cov tub ntxhais): Txoj kev no feem ntau yog siv ua ke nrog radial strapping. Nws lub luag haujlwm tseem ceeb yog ua kom ruaj khov ntawm cov hlau kauj rau lub hauv paus kev txhawb nqa ncej (bracket) lossis ntoo thaiv, tiv thaiv lub kauj los ntawm dov rov qab thaum thauj.
Lub hauv paus ntsiab lus tseem ceeb: Cov hlua khi yuav tsum tau muab faib ua symmetrically, thiab cov locking buckles (cov pob qij txha) yuav tsum muaj kev ruaj ntseg thiab nyiam dua sab hauv los yog tib txoj kev kom tsis txhob snagging thaum nqa.
4.Dab tsi yog qhov yuav tsum tau tshwj xeeb rau kev ntim khoom txias - dov coils nrog precision nto qhov yuav tsum tau (xws li automotive panels)?
Kev ntim khoom tsis sib cuag: Lub nplhaib sab hauv siv lub tes tsho daim ntawv rau kev txhawb nqa, thiab lub nplhaib sab nraud yog tag nrho qhwv nrog cov duab los qhia / yas tiv thaiv vaj huam sib luag, kom ntseeg tau tias tsis muaj cov hlua lossis cov khoom tawv ncaj qha rau ntawm cov hlau strips.
Kev huv huv sab hauv: Cov ntaub ntawv ntim khoom (xeb- ntawv pov thawj, yas zaj duab xis) yuav tsum muaj plua plav-dawb thiab halogen-dawb kom tsis txhob muaj tshuaj lom neeg nrog cov phaj hlau nyob rau hauv siab - qhov kub thiab txias ib puag ncig, uas tuaj yeem ua rau pob dawb lossis xeb.
Nqus los yog Inert Gas Filling: Rau kev xa tawm lossis dej hiav txwv- cov khoom thauj khoom thauj, nqus lossis ntim nrog cov cua qhuav / nitrogen yuav ua nyob nruab nrab ntawm lub ntim sab hauv thiab sab nrauv kom txo qis oxygen thiab noo noo hauv ntim.
Kev Tswjhwm nruj nruj: Txhua lub pallets ntoo yuav tsum tau ua kom qhuav thiab fumigation kev kho kom tsis txhob muaj cov evaporation ntawm noo noo los ntawm ntoo nws tus kheej los ntawm kev ua rau cov hlau kauj mus xeb.
5.Tom qab ntim, yuav tsum tau ceev faj dab tsi thaum lub sij hawm sau npe thiab txheej txheem stacking?
Ntshiab thiab ruaj ntseg Labeling: Ib daim ntawv lo ruaj ntseg uas muaj cov ntaub ntawv xws li cov khoom, specifications, hnyav, thiab lub cub tawg batch tooj yuav tsum tau affixed los yog dai rau ntawm lub ntim txheej. Daim ntawv lo yuav tsum tsis muaj dej tsis zoo thiab tsis yooj yim detached, qhov zoo tshaj plaws muab tso rau hauv qhov chaw so rau sab nrauv ntawm lub ntim kom tsis txhob khawb thaum nqa. Rau kev xa tawm coils, kev saib xyuas kuj yuav tsum tau them rau qhov tseeb ntawm cov cim xa khoom thiab cov lus xav tau.
Stacking Limits: Txawm tias thaum ntim, txias -rolled coils tsis tuaj yeem muab tso ua ke tsis tas li. Feem ntau, lub ntsiab coil (loj coil) tuaj yeem muab tso rau hauv ib txheej nkaus xwb, lossis ntau tshaj ob txheej, thiab lawv yuav tsum tau ua raws vertically siv cov khoom siv los tiv thaiv -slip ntoo pads. Kev sib tsoo ntau dhau tuaj yeem ua rau cov hauv qab coils deform vim lub ntiajteb txawj nqus, thiab tej zaum yuav ua rau lub ntim thiab cov hlua sab hauv puas.
Lifting Iav Matching: Lub ntim tsim yuav tsum xav txog txoj kev nqa (piv txwv li, C-hooks, kab rov tav lifting iav). Yog hais tias cov coils xav tau ntsug nqa, cov hlua ncig yuav tsum muaj zog txaus los tiv thaiv lub zog shear tseem ceeb thaum tig.
