Nyob rau hauv lub ntiaj teb no ntawm steel manufacturing, cov ntsiab lus "kub-dov coil" thiab "txias dov kauj" yog nquag ntsib. Ob hom khoom hlau no ua haujlwm sib txawv thiab tsim los ntawm cov txheej txheem sib txawv, ua rau muaj kev hloov pauv hauv lawv cov khoom, kev siv, thiab nqi. Nyob rau hauv no blog, peb yuav delve rau hauv lub tsom xam ntawm qhov sib txawv ntawm kub-dov coil thiab txias-dov coil khoom, nrog rau ib tug tshwj xeeb tsom rau specifications, pricing, thiab qhia txog txoj kev.
Dab tsi yog Kub Rolled thiab Cold-Rolled Coils?
Ua ntej peb tshawb nrhiav qhov sib txawv, nws yog ib qho tseem ceeb kom nkag siab tias cov kub dov thiab txias dov yog dab tsi.
Kub Rolled Coils : yog tsim los ntawm cov cua sov hlau saum toj no nws qhov kub thiab txias recrystallization, uas tso cai rau nws kom yooj yim zoo li tus thiab tsim. Cov txheej txheem no ua rau cov khoom uas feem ntau yog thicker thiab muaj ib tug ntxhib deg tiav. Lub thickness ntau rau kub-dov coils yog feem ntau ntawm 1.2 hli mus rau 25.4 hli.
Cold-Rolled Coils : ntawm qhov tod tes, yog tsim los ntawm kev ua cov khoom kub-kuav los tiag ntawm chav tsev kub. Cov txheej txheem no txhim kho lub zog thiab qhov chaw tiav ntawm cov hlau, ua rau cov khoom lag luam thinner nrog lub ntsej muag du. Lub thickness ntau rau txias-dov coils feem ntau yog nruab nrab ntawm 0.3 hli mus rau 3.5 hli.
Qhov sib txawv tseem ceeb ntawm Cov Kub Rolled thiab Cold-Rolled Coils
1. Specification Thickness
Ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws ntawm cov kub dov thiab txias dov yog lawv cov tuab. Raws li tau hais ua ntej, cov coils txias dov feem ntau yog thinner, xws li ntawm 0.3 hli mus rau 3.5 hli, thaum kub-dov coils tuaj yeem ua tuab dua, xws li 1.2 hli txog 25.4 hli. Qhov sib txawv ntawm qhov tuab no ua rau cov coils txias txias dua rau cov ntawv thov uas xav tau qhov tseeb thiab nruj dua, xws li cov khoom siv tsheb thiab cov khoom siv.
2. Nto tiav
Qhov saum npoo ntawm qhov kub-dov coils feem ntau yog ntxhib thiab tej zaum yuav muaj nplai los ntawm cov txheej txheem cua sov. Nyob rau hauv sib piv, txias-kuav los tiag coils muaj ib tug du thiab ci ntsa iab nto vim lub txias ua hauj lwm txheej txheem, uas kuj yuav pab tshem tawm tej deg imperfections. Qhov sib txawv ntawm qhov chaw tiav no tuaj yeem yog qhov tseem ceeb rau cov ntawv thov uas qhov zoo nkauj thiab qhov zoo ntawm qhov chaw tseem ceeb.
3. Mechanical Properties
Cold-dov coils feem ntau pom muaj zog dua thiab hardness piv rau kub dov coils. Cov txheej txheem ua haujlwm txias ua rau cov khoom muaj zog thiab tensile lub zog ntawm cov hlau, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom zoo dua qub. Kub-dov coils, thaum yooj yim rau kev ua hauj lwm nrog vim lawv malleability, tej zaum yuav tsis muab tib theem ntawm lub zog.
4. Nqe
Thaum nws los txog rau tus nqi, cov khaub thuas dov coils feem ntau yog kim dua li cov coils kub. Qhov sib txawv ntawm tus nqi no tuaj yeem raug ntaus nqi los ntawm kev ua haujlwm ntxiv thiab tuav yuav tsum tau ua rau cov khoom txias-dov. Cov neeg tsim khoom thiab cov neeg siv khoom yuav tsum xav txog tus nqi no thaum xaiv cov hom coil tsim nyog rau lawv cov kev xav tau tshwj xeeb.
5. Cov ntawv thov
Kev siv cov kub-kuav los tiag thiab txias-kuav los tiag coils txawv heev vim lawv cov khoom sib txawv. Kub-dov coils feem ntau yog siv rau hauv kev tsim kho, kev tsim nkoj, thiab cov tshuab hnyav, qhov muaj zog thiab kav ntev yog qhov tseem ceeb. Cold-dov coils, ntawm qhov tod tes, feem ntau yog siv rau hauv kev tsim cov khoom siv, cov khoom siv tsheb, thiab cov khoom siv, qhov tseeb thiab qhov zoo ntawm qhov chaw yog qhov tseem ceeb.
Yuav ua li cas kom paub qhov txawv thiab txheeb xyuas cov khoom kub-kuav los tiag thiab txias-dov
Kev txheeb xyuas seb cov khoom siv hlau puas yog kub-dov los yog txias-dov tuaj yeem ua tau los ntawm ntau txoj hauv kev:
- Kev soj ntsuam pom: Kub-dov coils feem ntau muaj qhov ntxhib, nplaig, thaum txias-dov coils muaj qhov du, ci ntsa iab. Kev tshuaj xyuas qhov muag pom tau yooj yim feem ntau tuaj yeem muab qhov qhia ceev ntawm hom coil.
- Kev Ntsuas Thickness: Raws li tau hais dhau los, cov coils txias dov feem ntau yog nyias dua li cov coils kub. Kev ntsuas lub thickness tuaj yeem pab txheeb xyuas hom coil.
- Magnet Test: Cold-rolled steel feem ntau sib nqus ntau dua li cov hlau kub-dov vim nws cov ntsiab lus carbon ntau dua. Cov hlau nplaum tuaj yeem siv los ntsuas cov khoom sib nqus ntawm cov hlau.
- Mechanical Testing: Kev ntsuas tensile tuaj yeem muab kev nkag siab rau cov khoom siv kho tshuab ntawm cov hlau, pab kom paub qhov txawv ntawm cov khoom kub-dov thiab txias-dov.
