1.Qhov txheej txheem tseem ceeb yog dab tsi?
Cold Rolling (Thawj Cold Rolling) → Intermediate Annealing → Thib Ob Cold Rolling → Final Annealing / Kub Rolling
Thawj Txias Rolling: Ua tiav thawj zaug thickness thiab ua hauj lwm hardening.
Intermediate Annealing (Critical Step): Tshem tawm kev ua hauj lwm hardening los ntawm thawj qhov txias dov los ntawm recrystallization annealing, rov qab kho cov khoom yas thiab tsim cov xwm txheej rau tom ntej thib ob txias dov.
Thib ob Cold Rolling: Ntxiv thinning thiab hardening ntawm lub annealed mos substrate.
Kev kho cua sov kawg: Nyob ntawm qhov kev ua tau zoo kawg ntawm cov khoom (xws li, hardness, lub zog, toughness), qhov kawg annealing tej zaum yuav tsum tau, los yog me ntsis tempering tej zaum yuav tsim nyog los tswj cov ntawv zoo thiab nto tiav.
2.Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov scenarios thiab lub hom phiaj?
Tau txais Cov Lus Qhia Tshwj Xeeb Tshwj Xeeb (Ultra-thin strip):
Thaum lub hom phiaj tuab yog qis dua qhov kev txwv ntawm cov pa ib zaug - dhau lub tshuab txias txias (piv txwv li, tsawg dua 0.15mm, lossis txawm tias qis dua mus rau qib 0.05mm), ob chav txias dov yog ib txoj hauv kev zoo. Thawj qhov txias dov yog ua rau qhov nruab nrab tuab, ua raws li kev sib xyaw ua ke, thiab tom qab ntawd ultra-thin dov yog ua tiav siv lub tshuab precision.
Tsim Ultra-High Strength los yog Cov Khoom Ua Haujlwm Tshwj Xeeb:
Los ntawm kev tswj hwm qhov txo qis ntawm ob txheej txheem txias dov thiab cov txheej txheem nruab nrab / kawg ntawm kev sib tsoo, cov nplej ua kom zoo thiab kev tswj kom zoo tuaj yeem ua tiav, ua rau muaj zog dua (piv txwv li, ultra- siab zog steel daim hlau) lossis cov khoom sib nqus tshwj xeeb (xws li, cov txheej txheem tsim khoom ntawm qee cov khoom siv hluav taws xob) piv rau ib zaug {{5}dhau txias dov.
Txhim kho Surface Quality los yog Sheet Shape:
Rau cov khoom uas tsis tshua muaj siab yuav tsum tau rau saum npoo tiav los yog daim ntawv zoo (xws li, ib co siab -kawg zoo nkauj panels, steel rau hluav taws xob Cheebtsam), annealing tom qab thawj txias dov thiab ib tug thib ob lub teeb dov tuaj yeem txhim kho qhov smoothness thiab flatness.
Kev tsim khoom yooj yim thiab me me -batch customization:
Qee qhov xwm txheej, ua kom dav dav - specification semi- cov khoom tiav (ib zaug -lub sij hawm txias- dov annealed coils) hauv Tshuag thiab tom qab ntawd rov- dov lawv raws li cov neeg siv khoom tshwj xeeb tuaj yeem txhim kho qhov hloov pauv ntawm lub koom haum tsim khoom.
3.Dab tsi yog cov teeb meem tseem ceeb thiab teeb meem uas peb ntsib?
Cov Khoom Siv Plasticity Txwv: Txawm hais tias cov khoom yas ntawm cov khoom siv rov qab los tom qab thawj zaug txias dov annealing, nws feem ntau qis dua qhov kub - dov raw cov ntaub ntawv. Tus nqi txo thaum lub sij hawm thib ob txias dov txheej txheem xav tau kev tswj kom meej; txwv tsis pub, cov teeb meem xws li strip breakage thiab ntug cracking muaj feem ntau.
Thickness thiab Performance Uniformity Control: Raws li qhov no yog "kev ua haujlwm thib ob," qhov yuav tsum tau ua rau zeb tswj precision (AGC), kev tswj cov txheej txheem yob, thiab cov txheej txheem lubrication yog siab dua kom ntseeg tau cov tuab tuab thiab kev ua haujlwm ntawm cov txheej txheem nyias nyias.
Surface Quality Risks:
Kev sib kis: Nruab nrab annealing thiab khaws cia / thauj cov txheej txheem tuaj yeem ua kom pom qhov paug paug (oxidation, roj, plua plav). Kev tu kom nruj yog qhov tseem ceeb ua ntej dov thib ob; txwv tsis pub, qhov tsis xws luag yuav raug nias rau saum npoo.
Roll Marks: Cov kev xav tau siab heev yog muab tso rau ntawm qhov chaw zoo thiab flatness ntawm cov yob. Txhua feeb yob nto qhov tsis xws luag yuav rov ua dua ntawm cov khoom nto.
4.Qhov no puas yuav nce nqi?
Cov txheej txheem ntxiv annealing, tu, thiab dov cov txheej txheem nce lub zog siv, lub sijhawm ua haujlwm, thiab cov khoom siv coj los ua, uas ua rau cov nqi tsim khoom ntau dua piv rau kev ua kom txias txias tas mus li, uas cuam tshuam rau ib qho txheej txheem.
Tus nqi tawm los yuav txo qis vim yog strip breakage thiab xaus -txiav thaum lub sij hawm ua haujlwm thib ob.
5.Dab tsi yog qhov kev ceev faj rau qhov txias txias thib ob ntawm qhov txias -rolled coils?
Rau cov khaub thuas zoo tib yam - cov ntawv dov thiab cov khoom siv strip nrog cov qauv tuab thiab cov kev xav tau ua haujlwm, ib qho txuas ntxiv ib zaug - txheej txheem txias dov yog qhov kev xaiv zoo tshaj plaws thiab kev lag luam.
Thaum cov khoom xav tau ntau tshaj qhov peev xwm ntawm cov txheej txheem ib txwm ua (xws li nyias nyias, ultra- lub zog siab, lossis cov khoom tshwj xeeb), ob-theem txias dov txheej txheem dhau los ua ib qho tseem ceeb ntawm txoj hauv kev.
