Daim phiaj hlau feem ntau muab faib ua peb hom raws li lawv tuab: Cov paib tuab (saum toj kawg nkaus ({4 m m mm) thiab nyias daim hlau (hauv qab 3 hli).
Hais txog ntawm phaj ua txheej txheem, cov phiaj roj khib nyiab tuaj yeem muab faib ua lub cev txias thiab kub dov. Kub dov ib leeg tuaj yeem tsim cov hlau roj carbon hlau ntawm txog li 1.2mm thiab stainless hlau daim hlau ntawm txog 2 hli. Thinner daim hlau yog tsim los ntawm txias dov, annealing thiab tempering dov.
Txias-Rolled Hlau Daim Hlau
Txias-dov daim hlau siv rau cov seem uas yuav tsum muaj qib loj ntawm cov khoom siv thaum lub sijhawm ua tiav, thiab yuav tsum tsis muaj wrinkles, kab nrib pleb, thiab lwm yam. Cov phiaj txheem sib txawv ntawm cov phiaj hlau siv rau ntau qhov chaw. Piv txwv li, cov qauv rau cov phiaj hlau txhais lus Japanese tau muab faib ua peb pawg. Thawj qeb (SpCC) yog dog dig-rolled steel daim hlau, uas ib txwm dov los ntawm cov hlau npau npau. Cov qeb thib ob (SPCD) yog cov phaj hlau rau dov, thiab cov qeb thib peb (SPCEN lossis SPCEN) yog txias-dov hlau daim hlau rau kev sib sib zog nqus duab.
Yav dhau los, Rimmed Steel tau txwv rau tsis tseem ceeb stamping ntu vim nws cov kev sib cais loj, tsis ruaj khov, thiab kev laus rhiab. Yog tias txhuas-tua cov hlau yam tsis muaj kev laus, tus nqi yuav 10-20}}% siab dua cov hlau rimmed. Yav dhau los, daim tawv nqaij dhau los ua kom tawg txias tau siv los ua kom muaj kev laus ntawm cov phiaj xwm steel, tab sis qhov tseeb nws tsuas yog ncua qhov tshwm sim ntawm kev laus. Txhua lub teb chaws tau kawm cov txheej txheem txhim kho tshiab. Cov xoob xoob me me steel phaj (OCA) tsim los ntawm Tebchaws Meskas yog ib qho kev sib tw ntawm cov cua sov uas muaj dej ntim thiab hydrogen. Txij li cov annealing hauv cov huab cua no tuaj yeem tshem tawm cov kev daws teeb meem thiab sib txuas ua ke rau hauv cov hlau, nws suppresses cov laus rhiab heev thiab txuas ntxiv mus muag cov hlau phaj. Nyob rau tib lub sijhawm, vim kev loj hlob ntawm cov nplej recrystallized, cov cheebtsam ntawm {111} kev sib sau ua lead ua ke sib txuas rau saum npoo ntawm cov hlau phaj nce. Raws li cov kev tshawb fawb ntawm Arma Steel tuam txhab hauv Tebchaws Meskas, qhov no muaj feem xyuam rau kev txhim kho cov phiaj yas, uas txhim kho cov qauv siv hluav taws xob yas ntawm 84%. Nyob rau hauv xyoo tsis ntev los no, ua ke annealing steel daim hlau (UAD) tau tsim los ntawm cov xoob xoob cov phiaj hlau. Qhov no yog rau weld ntau coils ntawm cov phaj hlau rau hauv ib coil thiab nruab lawv nyob rau hauv ib qho kev pab tshwj xeeb anuralburization. Nws qhov zoo dua yog tias nws tsis tshua kim tshaj cov xoob chev annealing. Cov paib hlau kho nyob rau hauv txoj kev no tau tshaj tawm nyob rau hauv khaub ncaws txias-rolled steel rau ncab.
Kub-Rolled Steel Daim Hlau
Cov txheej txheem tsim khoom yog yooj yim dua txias-rolled steel daim hlau thiab tus nqi kuj qis dua. Txawm li cas los xij, kev paub txawv teb chaws ntseeg tias cov txheej txheem kub kub tsuas yog tsim nyog rau tsim cov hlau hlau nrog ntau dua 1.6 hli, thiab nws tsis yog nyiaj txiag rau cov hlau thinner. Lub saum npoo zoo thiab sab qhov tseeb ntawm cov phaj kub tsis yog qhov zoo li cov phiaj txias-dov. Ntxiv rau hauv ncej ntev ntev teeb liab, hla kev sib tw, kub-rolled steel cov phiaj rau cov plhaub npog nrog lub zog tsis muaj zog thiab cov dej qis. Tus qub yog 3-5 nkauj tuab hlau phaj, thaum lub tom kawg yog siv rau nruab nrab thiab nyias daim hlau. Kev siv kub-rolled rhawv phiaj hauv cov tsheb feem ntau cov phiaj tuab. Nyob rau hauv lub cub kub style txheem rau lub tsheb tsim los ntawm kev sib koom tes ntawm nqaj thiab cov log, thiab sph yog lub tshuab kub kub
Tsis ntev los no, ntau thiab ntau dua kub-dov steel daim phiaj txawv teb chaws tau dov siv txuas txuas ntxiv steel hlau tau txhim kho thiab ruaj khov. Coiled kub-dov steel daim hlau tseem muaj dav siv.
