Dab tsi yog qhov txawv ntawm steel kauj thiab steel sawb?
Hlau kauj thiab steel sawb yog ob qho tib si khoom tsim los ntawm cov hlau, tab sis lawv muaj qee qhov sib txawv tseem ceeb uas paub qhov txawv ntawm ib leeg. Hauv tsab xov xwm no, peb yuav delve tob rau hauv qhov sib txawv no thiab tshawb txog lawv cov yam ntxwv, kev siv, thiab kev tsim khoom.
Steel Coil:
Lub steel kauj yog hais txog cov khoom lag luam tiaj tus, feem ntau ntawm qhov dav thiab tuab. Nws yog tsim los ntawm tsis tu ncua dov ib slab los yog billet los ntawm ib tug series ntawm dov mills kom ua tau raws li qhov xav tau thickness. Tom qab ntawd cov hlau coils raug mob rau hauv qhov loj, nruj nreem kaw los ntawm lub tshuab hu ua coiler lossis reeler.
Hlau Sawb:
Ntawm qhov tod tes, steel sawb yog qhov nqaim thiab sib dua ntawm cov hlau kauj. Nws kuj tseem ua tiav cov txheej txheem dov tib yam, tab sis lub hom phiaj kawg yog kom ua tiav cov tuab tuab dua thiab meej dua. Cov hlau sawb feem ntau raug mob rau hauv cov yob compact, hu ua coils, kom yooj yim ntawm kev khaws cia, kev thauj mus los, thiab kev ua haujlwm ntxiv.
Hlau Chev vs Steel Sawb: **
**1. Loj thiab Dimensions:
Ib qho ntawm qhov sib txawv ntawm cov hlau kauj thiab steel sawb yog nyob rau hauv lawv qhov loj thiab qhov ntev. Steel coils feem ntau dav thiab tuab dua piv rau steel strips. Cov coils tuaj yeem nyob ntawm ob peb ntiv tes mus rau ob peb taw hauv qhov dav, qhov strips feem ntau tsawg dua 12 ntiv tes dav.
2. Thickness:
Lwm qhov txawv ntawm cov hlau kauj thiab steel sawb yog lub thickness ntawm cov khoom. Hlau coils feem ntau tsim nrog ib lub thickness ntawm ob peb millimeters mus rau ob peb centimeters. Ntawm qhov tod tes, steel strips muaj cov tuab tuab, feem ntau ntsuas hauv feem ntawm ib millimeter.
3. Nyhav thiab Ntev:
Vim lawv qhov sib txawv, steel coils yog hnyav dua piv rau steel strips. Qhov hnyav ntawm steel kauj tuaj yeem sib txawv nyob ntawm nws qhov loj thiab tuab, txij li ob peb puas kilograms mus rau ob peb metric tons. Conversely, steel strips kuj sib zog, ua rau lawv yooj yim mus lis thiab thauj.
Qhov ntev ntawm steel kauj lossis sawb tuaj yeem sib txawv raws li qhov yuav tsum tau ua thiab cov neeg siv khoom tshwj xeeb. Ob leeg steel coils thiab strips tuaj yeem txiav rau qhov ntev raws li daim ntawv thov xav tau.
4. Nto tiav:
Qhov nto tiav ntawm steel kauj thiab steel sawb kuj tuaj yeem sib txawv. Steel coils feem ntau muaj ib tug du thiab ci tiav vim yog dov thiab annealing txheej txheem lawv undergo. Qhov kev ua tiav no yog qhov tsim nyog rau cov ntawv thov uas zoo li tseem ceeb, xws li hauv kev lag luam tsheb.
Hlau strips, ntawm qhov tod tes, tej zaum yuav muaj ntau yam ntawm cov khoom tiav, suav nrog zeb tiav, pickled thiab oiled, galvanized, los yog coated nrog lwm yam khoom. Kev xaiv ntawm qhov chaw tiav yog nyob ntawm daim ntawv thov npaj thiab cov khoom xav tau ntawm cov hlau sawb.
5. Daim ntawv thov:
Hlau coils thiab steel strips pom siv nyob rau hauv ntau yam lag luam thiab kev siv. Txawm li cas los xij, lawv cov ntawv thov tshwj xeeb feem ntau txawv vim lawv cov yam ntxwv sib txawv. Cia peb tshawb txog qee qhov kev siv rau txhua tus:
Steel Coil Applications:
- Kev tsim cov hlau loj loj thiab cov khoom siv
- Automotive kev lag luam (lub cev vaj huam sib luag, chassis, thiab lwm yam)
- Kev tsim kho kev lag luam (ru tsev, cladding, thav duab, thiab lwm yam)
- Lub zog sector (pipelines, tso tsheb hlau luam, transformers, thiab lwm yam)
- Cov khoom siv hauv tsev (qhov cub, tub yees, thiab lwm yam)
Daim ntawv thov Steel Strip:
- Precision engineering (caij nplooj ntoos hlav, ntxhua khaub ncaws, bearings, thiab lwm yam)
- Kev lag luam hluav taws xob (transformer laminations, circuit breakers, thiab lwm yam)
- Kev lag luam ntim khoom (hlau pluaj, ntsaws ruaj ruaj, thiab lwm yam)
- Automotive kev lag luam (cov khoom me me, cov khoom siv hluav taws xob, thiab lwm yam)
- Kev lag luam textile (loom reeds, heddles, thiab lwm yam)
6. Cov txheej txheem tsim khoom:
Thaum ob qho tib si steel coils thiab steel strips yog tsim los ntawm cov txheej txheem dov, qee qhov sib txawv muaj nyob hauv lawv txoj kev tsim khoom.
Hlau Coil Manufacturing:
- Initial processing: Cov khoom pib nrog melting hlau, ua raws li cov txheej txheem refining kom ua tiav qhov xav tau muaj pes tsawg leeg thiab zoo.
- Nruam casting: Cov hlau molten yog cam khwb cia rau hauv cov pwm loj hu ua slabs lossis billets.
- Kub dov: Cov slabs / billets yog reheated thiab dhau los ntawm ib tug series ntawm dov mills kom txo tau cov thickness thiab nce qhov dav.
- Txias thiab coiling: Cov kab hluav taws kub dov tau txias sai, ces coiled rau hauv cov yob loj siv lub coiler lossis reeler.
- Kev khaws cia thiab kev thauj mus los: Cov coiled steel coils tau muab khaws cia rau hauv lub tsev rau khoom lossis thauj mus rau cov neeg siv khoom kom ua haujlwm ntxiv lossis siv.
Steel Sawb Manufacturing:
- Zoo sib xws pib ua thiab nruam casting ib yam li hauv steel coil manufacturing.
- Kub dov: Cov slabs / billets yog dov ntawm qhov kub siab dua kom ua tiav cov hlau ntsuas nyias.
- Txias dov: Cov kub-dov strip yog txo qis hauv thickness los ntawm txias dov mills. Cov txheej txheem no imparts meej thickness tswj thiab txhim kho nto tiav.
- Annealing: Cov khaub thuas-kuav los tiag strip yog annealed kom tshem tawm cov residual stresses thiab txhim kho txhua yam khoom.
- Recoiling: Cov sawb annealed yog recoiled rau hauv me me coils kom yooj yim tuav thiab cia.
- Kev ua haujlwm ntxiv: Cov hlau strips tuaj yeem ua cov txheej txheem ntxiv xws li txheej txheej, galvanizing, lossis pleev xim, nyob ntawm seb cov khoom xav tau thiab kev siv.
Hauv kev xaus,thaum steel coil thiab steel sawb yog ob qho tib si ua los ntawm cov hlau, lawv txawv ntawm lawv qhov loj, tuab, qhov hnyav, nto tiav, kev siv, thiab kev tsim khoom. Hlau coils yog dav, tuab, thiab hnyav dua, thaum steel strips yog nqaim, nyias, thiab sib dua. Qhov saum npoo ntawm cov coils feem ntau yog du thiab ci, whereas strips tuaj yeem muaj ntau yam tiav. Ob leeg muaj ntau yam kev siv hauv kev lag luam uas vam khom cov khoom tshwj xeeb ntawm txhua hom. Kev nkag siab txog qhov sib txawv no yuav pab xaiv cov khoom siv hlau tsim nyog rau cov kev cai tshwj xeeb.
