1.Dab tsi yog lub luag haujlwm tseem ceeb ntawm lub coil core (los yog steel coil spindle)?
Xyuas kom ntau lawm: ruaj khov uncoiling thiab rewinding ntawm cov khoom xws li dov mills, galvanizing kab, thiab annealing furnaces.
Kev ruaj ntseg thiab kev thauj mus los: Ua haujlwm raws li kev txhawb nqa thiab kev ntxhov siab thaum lub sij hawm hoisting, stacking, thiab tsheb thauj mus los, bearing hnyav hnyav ntawm steel coils lawv tus kheej.
2.Dab tsi yog lub zog ntawm lub hauv paus tseem ceeb tiv thaiv thaum khaws cia thiab kev thauj mus los?
Compression/Radial Pressure: Thaum steel coils yog stacked tiaj tus ("ntev-"), cov tub ntxhais ntawm lub hauv qab kauj yog compressed los ntawm qhov hnyav ntawm coils saum toj no.
Bending Stress: Thaum steel coils raug muab tso rau upright ("standing") thiab hoisted siv C-hooks los ntawm cov tub ntxhais, cov tub ntxhais ua zoo li ib tug nqaj, bearing lub dabtsi yog khoov quab yuam tsim los ntawm qhov hnyav ntawm tag nrho cov kauj.
3.Dab tsi yog qhov tseem ceeb cuam tshuam rau kev thauj khoom -cov kabmob muaj peev xwm ntawm cov tub ntxhais yob?
Cov ntaub ntawv tseem ceeb: Cov tub ntxhais hlau: Feem ntau, muaj zog, rov siv tau. Muaj zog load-cov kabmob muaj peev xwm. Fiber core: Siv rau cov yob sib zog (xws li qee cov aluminium coils, nyias steel coils), tus nqi qis, rau kev siv ib zaug. Tsawg heev load-cov kabmob muaj peev xwm.
Core phab ntsa thickness: Qhov no yog ib qho tseem ceeb tshaj plaws. Cov phab ntsa tuab dua, qhov muaj zog tiv thaiv compression thiab khoov. Feem ntau steel tub ntxhais phab ntsa thicknesses li ntawm ob peb millimeters mus rau ntau tshaj kaum millimeters, thiab zoo correlated nrog lub luj ntawm steel kauj.
Core puab txoj kab uas hla: Muaj qee cov qauv puab diameters hauv kev lag luam, xws li 508mm (20 nti) thiab 610mm (24 nti). Qhov loj dua lub puab lub cheeb, cov hlau ntau dua yuav siv tau rau cov tub ntxhais (phab ntsa thickness yuav thicker), thiab lub zog load- bearing peev feem ntau yog.
4.Dab tsi yog kev lag luam- qauv kev coj ua thiab "tus qauv"?
Cov Qauv Tsim Qauv: Cov kws tshaj lij cov tuam txhab muab cov kev nyab xeeb siab tshaj plaws - cov kabmob muaj peev xwm rau cov cores ntawm cov qauv sib txawv (sab hauv kab × phab ntsa thickness × ntev) raws li cov qauv ntawm cov khoom siv tshuab. Qhov no yog qhov ncaj tshaj "tus qauv."
Stacking Layer Limits: Txhawm rau kom muaj kev nyab xeeb, muaj cov kev cai nruj txog cov txheej txheem ntawm cov pav ca -ntev steel coils uas tuaj yeem muab tso rau hauv warehouses thiab logistics. Feem ntau:
Heaviest steel coils (e.g., >10 tons): Feem ntau stacked hauv 1 txheej.
Nruab nrab- hnyav steel coils: Stacked nyob rau hauv ntau tshaj 2 txheej.
Lub teeb steel coils: tuaj yeem muab tso rau hauv 3 txheej, tab sis nws yuav tsum tau ua kom ntseeg tau tias cov tub ntxhais hauv qab thiab lub hauv paus muaj peev xwm txaus- cov kabmob muaj peev xwm.
Txhua yam dhau 3 txheej yog txwv tsis pub, vim tias qhov siab ntawm cov tub ntxhais hauv qab nce exponentially.
Safety Factor: Thaum tsim cov load- bearing peev xwm ntawm cov tub ntxhais, ib tug loj kev nyab xeeb yam (piv txwv li, 3-5 zaug) yog qhia kom muaj kev ruaj ntseg nyob rau hauv cov xwm txheej tsis tau xav txog xws li dynamic impacts (xws li, swaying thaum hoisting).
5.Dab tsi yog qee cov lus qhia ua haujlwm nyab xeeb?
Clear Labeling: Qhov hnyav yuav tsum tau qhia meej meej ntawm daim ntawv lo ntawm cov hlau kauj. Qhov zoo tshaj plaws, cov tub ntxhais tseem yuav tsum muaj kev thauj khoom -cov kabmob cim.
Zoo Lifting:
Siv ntsug C-hooks rau nqa, vim qhov no yog qhov kev ntxhov siab tshaj plaws- tus phooj ywg txoj hauv kev rau lub hauv paus.
Thaum siv cov hlua hlau rau kev nqa los ntawm cov tub ntxhais, cov ces kaum yuav tsum tau muab ntsia kom tiv thaiv cov hlua hlau los ntawm kev txiav cov phab ntsa sab hauv ntawm cov tub ntxhais.
Kev Txhaum Cai Zoo:
Ua tib zoo ua raws li cov txheej txheem stacking txwv.
Thaum stacking kab rov tav, nplooj siab ntoo blocks los yog kev txhawb nqa yuav tsum tau siv ntawm cov khaubncaws sab nraud povtseg los xyuas kom meej kev sib raug zoo ntawm lub sab sauv thiab sab cores thiab tsis txhob ncaj qha compression ntawm steel sawb.
Lub hauv paus yuav tsum ruaj thiab qib.
Tshawb xyuas qhov tseem ceeb: Ua ntej nqa, tshuaj xyuas cov tub ntxhais kom pom qhov flattening, tawg, lossis deformation loj. Yog tias pom muaj kev puas tsuaj, nres siv tam sim ntawd.
