1.What yog cov yam ntxwv tseem ceeb ntawm cold-} rolled steel?
Zoo heev nto zoo
Cov txheej txheem txias txias tshem tawm cov txheej txheem siab siab - qhov kub thiab txias oxidation, ua rau muaj kev du, txawm tias saum npoo. Dawb ntawm cov hlau oxide nplai ("dub nplai") nquag ntawm- Laminating, thiab vuam) yam tsis muaj kev tshem tawm ntxiv lossis xeb. Nws yog tsim nyog tshwj xeeb rau cov ntaub ntawv uas yuav tsum tau ua kom zoo nkauj (xws li cov cuab yeej siv hauv tsev thiab tsheb).
Siab sab downensional qhov tseeb
Lub txias dov lub zeb zeb lub ruaj khov rolling siab siab tso cai rau kev tswj hwm ntawm cov hlau lub thickness sib txawv (feem ntau tsawg dua lossis sib npaug ntawm ± 0.02 hli). Nws cov tiaj tiaj tiaj tiaj tshaj li ntawm kub kub- rolled steel, ntsib kev ua haujlwm uas xav tau ntawm cov khoom siv hluav taws xob (xws li cov cuab yeej siv hluav taws xob (xws li cov cuab yeej siv hluav taws xob (xws li cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob (xws li cov cuab yeej siv hluav taws xob).
Muaj Zog Cov Khoom Siv Hluav Taws Xob
Chav {{0 - kub rolling ua cov "ua haujlwm hnyav" nyhuv ntawm cov hlau. Lub zog tensile, tawm los dag zog, thiab siv lub zog ntawm Q235}}}}}}} {9} {rolled steel yog kwv yees li 370-500MPA, tab sis cov txiaj ntsig lub zog ntawm cov hlau txias-rolled steel yog siab dua). Txawm li cas los xij, ductility yog txo me ntsis (qhov no yuav tsum tau hloov kho los ntawm "annealing" txheej txheem). Nqaim tuab ntau yam
Txias -} rolled steel yog feem ntau thinner Kub - rolled hlau, ntawm qhov tod tes, feem ntau yog tuab dua 3mm thiab haum rau cov ntawv phaj tuab.
Du puab puab
Tom qab dov tawm, tus hlau phaj undergoes flatenening ntawm daim tawv nqaij -}}}}}}}}}} Kev tsis xws luag xws li Camber thiab Tsw. Qhov no txo kev deformation thaum lub sijhawm txiav thiab khoov, ua kom muaj kev ruaj ntseg siab.
2.Qhov cov ntaub ntawv tseem ceeb thiab cov kev faib tawm ntawm cov khaub thuas- rolled daim hlau?
Tsawg -} paab carbon txias - cov ntsiab lus tsawg dua los yog sib npaug rau 0.25%, zoo vuam. Siv hauv cov khoom siv hauv tsev, cov tswv yim tsheb kho tsheb, thiab cov khoom siv tau txais khoom (xws li cov ntawv xa khoom).
High - Lub Zog Txias-}} rolled steel xws li manganium, nws muaj lub zog siab thiab lub zog loj. Siv Kev Siv Tsheb, Chassis Cheebtsam, thiab cov qauv txheem rau kev siv tshuab.
Mob khaub thuas zoo tib yam - rolled steel (Oxidation Txheej (Oxidation Txheej), muaj tus nqi qis, thiab siv rau cov txheej txheem zais cia.
Galvanized txias - rolled steelized (hluav taws xob galvanized (siv rau cov khoom siv hauv tsev sab nraum zoov thiab tsheb npog sab nraum zoov.
3.Qhov dab tsi yog qhov tseem ceeb ntawm qhov txawv ntawm txias - rolled thiab kub- rolled daim hlau?
Rolling Kub: Txias dov lub phaj ntawm chav tsev kub (tsawg dua los yog sib npaug nrog 500 degree), tsis muaj oxidizing cua sov; Kub lub phaj ntawm qhov kub kub (ntau dua lossis sib npaug nrog 900 degree, billet xeev), muaj cua sov
Cov phiaj xwm zoo: Cov paib muab rhaub yog tus thiab tsis muaj oxide nplai thiab tuaj yeem siv ncaj qha; Kub cov paib yog ntxhib thiab muaj oxide nplai (cov tawv nqaij dub) thiab xav tau kev xaiv.
Qhov tseeb ntawm qhov tseeb: Siab rau cold - rolled daim hlau (me me thickness sib txawv, zoo nkauj zoo); Tsawg rau kub - rolled daim hlau (loj thickness hloov kev hloov pauv, nquag mus rau laim ntoom)
4.Qhov twg yog cov chaw thov cov khoom siv ntawm cov hlau txias steel?
Kev Lag Luam Hauv Tsev: Tub Yees Sab Panels / Rov Qab Lub Housings / Lub Tshuab Ntxhua Khaub Ncaws, Microwave Cub Tso Tsheb Hlau, thiab lwm yam.
Kev Lag Luam Automotive: Lub qhov rooj, Hoods), Khoom Siv Hluav Taws Xob (Khoom Sib Nrauj Kab (xws li roj yeeb nkab nkhaus).
Kev lag luam hluav taws xob: Cov ntaub ntawv computers, ntsiav tshuaj txawb / ntsiav tshuaj, tshuab luam ntawv lub tsev (precision qhov ntev yuav tsum tau).
Kev tsim kho thiab rooj tog zaum: sab hauv phab ntsa panels rau cov rooj ua ntej, cov rooj tog zaum steel (khoom ntim, cov hlau ua kom zoo nkauj.
Cov Khoom Kho Vajtse: Cov neeg siv khoom siv kho vajtse (xws li txiab thiab riam cov pob khoom siv), cov gaskets, thiab cua txias (tawv {rolled hlau).
5.Qhov twg yog qhov kev ceev faj txog kev siv khaub thuas- rolled steel?
Rust kev tiv thaiv: dog dig txias - rolled steel tsis muaj ib tug xeb thiab yog kev tiv thaiv kom noo thiab xeb. Nws yuav tsum muab cia rau hauv ib puag ncig qhuav thiab zam nrog dej, acids, lossis alkalis. Yog tias raug rau ncua sijhawm tom qab kev ua, nws yuav tsum tau pleev xim kom sai lossis galvanized.
Ua cov kev haum: cua txias txias- rolled steel muaj tsis tau bent fortensully (li nws yog nquag mus tawg). Xaiv cov muag muag lossis semi- cov qhab nia nyuaj raws li kev yuav tsum tau ua. Zam cov ces kaum ntse thaum khoov los tiv thaiv kev ntxhov siab.
Kev siv vuam: Tsawg {{-}} rolled steel cape tuaj yeem welding welding thiab chaw vuam. Txawm li cas los xij, tom qab vuam, tshem tawm weld shag thiab thov ib qho repaint los tiv thaiv cov xeb ib puag ncig. Ua ntej vuam siab - lub zog txias - rolled steel yog sib xws yog sib xws (kom tsis txhob muaj weld weld muaj zog).
Xaiv qhov loj me: "Ua haujlwm hnyav" ntawm txias - rolled steel tuaj yeem ua rau ntug dej me ntsis tom qab txiav. Ib qho me me npoo npoo (feem ntau 0.1-0.2mm) yuav tsum raug tso cai thaum tsim chaw.
