Dab tsi yog txias -rolled steel?
Txias-rolled steel yog hais txog cov hlau ua tiav los ntawm kub- dov steel coils ua raw khoom, los ntawm ntau cov txheej txheem dov ntawm chav tsev kub (hauv qab qhov kub ntawm recrystallization). Piv nrog rau cov kub-rolled steel, txias-rolled steel undergoes thib ob dov thiab nto tiav kev kho mob, uas ua rau muaj ntau dua dimensional raug, superior mechanical zog, thiab ib tug smoother thiab finer nto zoo.
Core Advantages ntawm Cold Rolled Steel
| Qhov zoo | Kev piav qhia |
|---|---|
| Zoo heev Surface Quality | High deg smoothness thiab zoo tag, haum rau painting, plating, txheej thiab lwm yam txheej txheem kho deg. |
| High Dimensional Precision | Tight thickness kam rau ua thiab superior flatness, kom ntseeg tau muaj zog applicability rau precision manufacturing industries. |
| Zoo Formability | Zoo tagnrho rau stamping, dabtsi yog khoov, sib sib zog nqus daim duab thiab lwm yam txheej txheem, raws li complex ib feem tsim yuav tsum tau. |
| Uniform Mechanical Properties | Refined grain qauv ua kom ruaj khov lub zog, plasticity thiab siab cov khoom sib xws. |
| Eco-Tus phooj ywg qis- Cov khoom siv carbon | Cov ntsiab lus tsis tshua muaj cov pa roj carbon monoxide pab txhawb kev tsim khoom ntsuab, ua raws li kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov. |
2025 Cold Rolled Steel Nqe
Tseem ceeb:steel coil cov nqi hloov pauv txhua hnub nrog cov khoom seem, hluav taws xob, nqi tariffs, thiab cov khoom lag luam hauv cheeb tsam. Cov duab hauv qab no yog nruab nrab ntawm -2025 kev lag luam ntsuas kev lag luam sib sau ua ke los ntawm kev lag luam nqe lus ceeb toom - siv lawv rau kev siv nyiaj txiag thiab kev sib tham, tsis yog cov lus hais ruaj khov. Qhov tseeb ex-mill lossis FOB tus nqi yuav txawv ntawm zeb, kom muaj nuj nqis, chaw nres nkoj xa khoom thiab nqe lus cog lus.
| Thaj tsam | Mid-2025 qhia tus nqi (USD / metric tonne) | Sau ntawv / qhov chaw |
|---|---|---|
| Teb Chaws Asmeskas (CRC chaw ntau) | ~ 1,050 - 1,130 USD / MT | Teb Chaws Asmeskas txias- dov qhov chaw nyob nruab nrab-2025 tshaj tawm ntawm ~ 1,057–1,130 USD / MT. Cov nqi tuaj yeem siab dua rau cov ntawv pov thawj kos duab zoo coils. |
| Northern / Western Europe (CRC ex-mill) | ~ 900 – 1,050 USD / MT (≈ € 820 – € 960) | European ex-mill CRC indices varied; cov nqi hluav taws xob thiab hluav taws xob hluav taws xob ua rau muaj kev hloov pauv hauv cheeb tsam. Siv cov ntsuas hauv cheeb tsam Fastmarkets rau kev taug qab txhua lub lim tiam. |
| Tuam Tshoj (hauv tsev CRC chaw, RMB hloov dua siab tshiab) | 3,700–4,000 RMB/MT (~520–560 USD/MT) | Suav chaw nyob hauv tsev rau txias-cov ntawv dov tau tshaj tawm nyob rau hauv 3,700–3,980 RMB / MT thaj tsam nruab nrab -September 2025 (cov chaw hauv zos). Tus nqi xa tawm nyob ntawm qhov chaw nres nkoj, qib thiab qhov ntau. |
Yuav ua li cas nyeem cov kab no
Teb Chaws Asmeskas kev lag luam tau pom CRC ntau dua ib nrab ntawm -2025 vim yog cov nqi hauv tsev thiab kev txiav txim siab nqi se; Cov nqi European txav nrog cov nqi hluav taws xob thiab cov khoom seem; Tuam Tshoj qhov chaw hauv tsev feem ntau qis dua tab sis cov nqi xa tawm, kev ua haujlwm, thiab kev thauj mus los ntxiv rau tus nqi xa khoom. Rau kev sib piv RFQ meej, thov ex- ua haujlwm thiab FOB xaiv thiab suav nrog cov ntawv pov thawj thiab cov chav kawm saum npoo kom ntseeg tau cov txiv apples -rau-apples quotes.
FAQs
Q: Cov qib DC puas tuaj ua ntej-galvanized?
A: EN 10130 npog cov khoom tsis muaj coated; Galvanized variants yog muab raws li EN 10152 (DC + ZE). Qhia kom meej txheej txheej thiab tom qab- kho thaum yuav tsum tau muaj kev tiv thaiv corrosion.
Q: Kuv yuav ua li cas thiaj ua tau zoo sib xws ntawm cov coils?
A: Yuav tsum tau MTCs, nug mills rau cov txheej txheem tswj cov ntaub ntawv (annealing lub sij hawm), thiab khaws ntau qhov ntau thiab tsawg coherent rau kev khiav ntau lawm. Xav txog qhov khoob ntawm tib tus naj npawb cua sov rau qhov tseem ceeb.
Q: Dab tsi kam rau ua yog raug rau 0.8 hli thickness?
A: Tolerances nyob ntawm zeb thiab thickness band; EN cov qauv txhais cov thickness ntau npaum li cas - qhia rau ntawm PO thiab thov daim ntawv ua siab ntev rau zeb.
Q: Ua li cas txias -rolling cuam tshuam cov khoom sib nqus?
A: Txias dov me ntsis nce cov txiaj ntsig thiab lub zog thiab tuaj yeem ua kom cov hlau nplaum permeability anisotropy; qhia cov kev cai sib nqus yog tias tsim nyog rau cov khoom siv hluav taws xob.
