1. Puas tuaj yeem txias -cov coils tiag tiag siv los ua cov khoom siv?
Yog lawm, txias- dov coils yog cov khoom siv dav dav thiab paub tab rau kev tsim cov khoom siv.
Txias-cov ntawv yob steel yog siv dav hauv cov khoom siv hauv tsev, chassis, thiab txee kev lag luam. Lawv feem ntau yog siv los tsim cov khoom siv sawv ntsug, lub tshuab sawv ntsug, thiab cov txee sawv, cov khoom siv ncaj qha txiav txim siab qhov ruaj khov thiab ua haujlwm ntev ntawm cov cuab yeej.
Hauv cov ntawv thov tshwj xeeb, txias-rolled coils muaj keeb kwm ntev ntawm kev siv rau cov khoom muag. Piv txwv li, lub tshuab ntxhua khaub ncaws thiab cov khoom siv txhawb nqa sab hauv rau cov tub yees hauv kev lag luam khoom siv hauv tsev yog cov ntawv siv txias- dov steel.
2. Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv txias -rolled coils rau cov khoom siv hauv paus?
✅ Qhov zoo
Tus nqi zoo: Txias-cov ntawv yob steel yog tus nqi pheej yig, muab tus nqi zoo- ua tau zoo. Tus nqi ntawm cov khaub thuas zoo tib yam - dov steel yog kwv yees li ib nrab ntawm cov hlau tshwj xeeb, txo cov nqi tsim khoom.
Kev Ua Haujlwm Zoo Tshaj Plaws: Txias- cov hlau dov yog yooj yim los txiav, khoov, stamp, thiab vuam, ua rau nws zoo tagnrho rau kev tsim cov hauv paus uas xav tau cov duab nyuaj. Qhov no ua rau muaj kev ua haujlwm siab thiab tsim nyog rau kev tsim khoom loj.
High Dimensional Accuracy: Vim yog chav tsev kub dov, txias- cov ntawv hlau dov muaj qhov zoo ntawm qhov raug (xws li thickness kam rau ua) thiab nto flatness, ua tau raws li qhov yuav tsum tau ua ntawm precision sib dhos.
Zoo Nto Zoo: Lub npoo du ntawm qhov txias txias - cov ntawv yob steel ua rau lawv zoo tagnrho substrate rau tom qab kho nto xws li tha xim thiab electroplating, uas ua rau lub ntsej muag zoo dua.
Qhov tsis zoo
Corrosion Resistance tsis zoo: Qhov no yog qhov tsis zoo tshaj plaws ntawm cov ntawv txias -rolled steel. Yog tsis muaj kev tiv thaiv kev kho mob, txias- dov steel yog qhov cuam tshuam rau xeb hauv qhov chaw ntub dej.
Yuav Tsum Tau Kev Kho Hniav: Vim nws qhov tsis haum rau xeb, tag nrho cov khaub thuas- cov ntawv yob steel siv rau hauv paus yuav tsum tau kho saum npoo, xws li electrostatic hmoov txheej lossis txau; txwv tsis pub, cov khoom lag luam lifespan yuav luv luv.
Daim ntawv thov txwv: Nws tsis muaj zog xeb ua rau nws tsis haum rau sab nraum zoov, av noo, lossis ntev -lub sij hawm corrosion- cov khoom siv hluav taws xob tiv taus. Hauv cov cheeb tsam no, galvanized steel lossis stainless hlau raug pom zoo.
3: Vim li cas ho xaiv txias- dov steel ntawv piv rau lwm cov ntaub ntawv?
Rau cov cuab yeej siv nyob rau hauv ib puag ncig sab hauv tsev, qhov twg tus nqi yog ib qho kev txhawj xeeb, thiab qhov twg cov txheej txheem tha xim muaj feem cuam tshuam, cov ntawv txias -rolled steel yog tus nqi siab heev - kev xaiv zoo. Yog tias lub hauv paus yuav tsum raug rau huab cua ntub rau lub sijhawm ntev, galvanized steel ntawv lossis stainless hlau yuav tsum tau muab qhov tseem ceeb.
4. Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov khoom siv thiab ua tiav lawv?
Thaum siv cov khoom txias- dov coils los tsim cov cuab yeej siv, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
Kev xaiv khoom siv:
Qib Xaiv: Cov qib siv feem ntau yog SPCC (kev lag luam-qib txias- dov steel ntawv). Rau cov hauv paus uas yuav tsum tau ua kom yooj yim stamping lossis ncab, SPCD, uas muaj cov qauv zoo dua, tuaj yeem xaiv.
Thickness Requirements: Lub thickness tsim nyog yuav tsum tau xaiv raws li qhov hnyav lub hauv paus xav tau dais thiab cov qauv tsim. Feem ntau thickness ranges ntawm 1.0mm thiab 3.0mm.
Standard Requirements: Tuam Tshoj muaj ib tug tshwj xeeb lub teb chaws tus qauv rau txias- dov steel ntawv thiab strips rau cov khoom siv hauv tsev (GB/T 30068-2025), uas qhia meej meej cov kev cai.
Kev Siv Tshuab:
Stamping thiab dabtsi yog khoov: Txias- cov nplooj ntawv steel yog zoo tagnrho rau stamping thiab dabtsi yog khoov, tso cai rau kom ua tau zoo fabrication ntawm lub hauv paus duab.
Welding Performance: Txias-cov ntawv hlau yob muaj qhov zoo weldability. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov vuam yuav ua rau lub ntsej muag xeb - pov thawj txheej; yog li ntawd, cov chaw welded yuav tsum raug xeb tom qab- pov thawj kev kho mob.
Kev kho deg (Critical):
Yuav tsum tau: txhawm rau tiv thaiv xeb, tag nrho cov khaub thuas- dov steel puag yuav tsum tau kho saum npoo, xws li electrostatic hmoov txheej lossis pleev xim. Qhov no yog kev coj ua hauv kev lag luam.
Sijhawm: Kev kho deg yuav tsum tau ua tom qab tag nrho cov txheej txheem machining (stamping, dabtsi yog khoov, vuam) ua tiav kom ntseeg tau tias tag nrho cov hlau raug npog.
5. Dab tsi yog kev lag luam kev lag luam? Dab tsi yog qhov kev cia siab rau txias- cov ntawv yob steel hauv cov khoom siv hauv paus?
Daim ntawv thov txias- dov steel coils hauv cov khoom siv hauv paus yog qhia txog qhov sib txawv ntawm qhov sib txawv, nrog rau qhov chaw ua lag luam tag nrho raug nyem los ntawm qib siab dua - cov ntaub ntawv qib.
Tsawg-kev ua lag luam kawg tseem siv: Tam sim no, daim ntawv thov ntawm cov khaub thuas zoo tib yam- dov steel hauv cov khoom siv hauv tsev tau raug compressed rau hauv qis- tus nqi- ntxiv cov khoom, xws li cov hauv paus qis- kawg tshuab ntxhua khaub ncaws thiab cov khoom txhawb nqa sab hauv ntawm kev nkag - theem cov tub yees. Hauv cov cheeb tsam no, tus nqi yog thawj qhov kev txiav txim siab.
High-kev ua lag luam kawg raug hloov pauv: Raws li cov khoom siv hauv tsev hloov pauv mus rau qib siab- kawg thiab cov khoom ntse, cov kev xav tau siab dua tau muab tso rau ntawm cov khoom siv. Piv txwv li, qhov yuav tsum tau ua siab ntev rau cov hlau hauv siab -kawg cov khoom siv hauv tsev tau nce mus rau ± 0.005mm, thaum qhov tseeb ntawm cov khaub thuas zoo tib yam -rolled steel tsuas yog ± 0.02mm, uas nyuaj rau kev sib ntsib. Qhov no tau ua rau txias- dov steel tau maj mam hloov los ntawm siab-cov ntawv ua haujlwm galvanized, xim- cov ntawv coated, lossis siab dua-zoo tshwj xeeb txias- dov steel hauv siab- khoom kawg.
Cov khoom siv kho dua tshiab yog qhov sib txawv: kev tsim khoom siv hauv tsev yog tsim los ntawm lub teeb yuag thiab siab corrosion kuj. Yuav kom ua tau raws li cov kev cai tshiab no, cov tuam txhab lag luam tau pib txais cov ntaub ntawv tshiab ntxiv. Piv txwv li, Baosteel tau tsim cov xim pleev xim rau -dawb txhuas-zinc- cov khoom siv hlau nplaum siv rau hauv cov cua txias sab nraum zoov chassis, hloov cov txheej txheem "kub-dip galvanizing + spraying" txheej txheem. Handan Iron thiab Steel Group kuj tau ua tus thawj coj hauv kev nthuav qhia aluminium-zinc-magnesium coated steel los xij rau hauv cov khoom siv hauv tsev.
