Kub Rolled Coil
Kub-dov coil yog cov khoom siv hauv kev lag luam steel. Nws yog tsim los ntawm cov txheej txheem kub kub dov thiab muaj cov yam ntxwv ntawm tus nqi qis, siab zog, thiab kev ua haujlwm zoo. Nws yog dav siv hauv kev tsim kho, tshuab, tsheb, nkoj tsim thiab lwm yam.
Basic txhais
Kub dov kauj (HRC) yog hais txog cov khoom siv hlau uas txuas ntxiv dov saum toj ntawm qhov ntsuas kub ntawm recrystallization (feem ntau> 900 ° C) los ntawm billets (xws li slabs lossis billets) thiab thaum kawg curled.
Qhov sib txawv ntawm cov khaub thuas dov kauj: Kub dov coil tsis yog txias dov, qhov saum npoo yog ntxhib, qhov tseeb qhov tseeb yog qhov tsawg, tab sis lub zog siab thiab cov ductility yog qhov zoo, uas yog tsim rau kev tsim cov khoom tsim.
Cov yam ntxwv tseem ceeb
| Yam ntxwv | Kub dov kauj | Cold dov kauj |
| Cov txheej txheem ntau lawm | Kub kub dov (> 900 ° C) | Qhov kub thiab txias dov (kev ua haujlwm txias) |
| Nto zoo | Oxide nplai, ntxhib | Smooth, siab precision |
| Lub zog | Tsawg (tab sis zoo toughness) | High (ua haujlwm hardening) |
| Nqi | Tsawg | Siab |
| Daim ntawv thov | Cov khoom siv, cov kav dej, cov khoom siv tsheb | Precision qhov chaw, khoom siv hauv tsev, automotive panels |
3. Cov txheej txheem ntau lawm
Cua sov: Lub steel billet yog rhuab mus rau 1100 ~ 1250 ° C kom soften nws.
Rough rolling: Ua ntej tsim los ntawm lub siab-siab dov zeb.
Tiav dov: Tswj lub thickness rau lub hom phiaj loj (xws li 1.2 ~ 20mm).
Coiling: Tom qab dov, nws yog dov rau hauv ib lub kauj hlau (feem ntau yog 1 ~ 2 meters nyob rau hauv txoj kab uas hla).
Txias: Kev ua kom txias lossis tswj kom txias (xws li txheej txheem TMCP).
Feem ntau specifications
Thickness: 1.2 ~ 25mm (ntau 2.0 ~ 6.0mm).
Dav: 600 ~ 2200mm (hom 1250mm, 1500mm).
Khoom siv: Q235B (dawb carbon steel), SS400 (Japanese standard), A36 (American txuj), S355JR (European standard).
Mechanical zog: tensile zog 300 ~ 500MPa, yield zog 200 ~ 400MPa.
Cov chaw ua haujlwm tseem ceeb
Kev tsim kho kev lag luam: H-beam, steel qauv, choj, steel bar.
Machinery manufacturing: engineering machinery, mining khoom, siab nkoj.
Automotive kev lag luam: ncej, log hub, chassis qauv.
Pipeline kev lag luam: welded yeeb nkab, kauv yeeb nkab (xws li API 5L pipeline steel).
Shipbuilding kev lag luam: nkoj phaj, bulkhead qauv.
Lub tuam txhab muab qhov tseem ceeb rau qhov zoo ntawm cov khoom, nqis peev ntau hauv kev qhia txog cov cuab yeej siv siab heev thiab cov kws tshaj lij, thiab tawm mus ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom hauv tsev thiab txawv teb chaws.
Cov ntsiab lus tuaj yeem faib ua roughly faib rau hauv: tshuaj muaj pes tsawg leeg, yield zog, tensile zog, tej yam khoom, thiab lwm yam
Nyob rau tib lub sijhawm, lub tuam txhab tseem tuaj yeem ua tiav kev tshawb nrhiav qhov tsis zoo hauv online thiab annealing thiab lwm yam kev kho cua sov raws li cov neeg siv khoom xav tau.
