Cov neeg siv khoom feem ntau nug peb txog qhov sib txawv ntawm kub dov steel thiab txias dov hlau.Muaj qee qhov sib txawv ntawm ob hom hlau no.Qhov sib txawv ntawm kub dov hlau thiab txias dov steel muaj feem xyuam rau txoj kev uas cov hlau no ua tiav ntawm lub zeb, thiab tsis yog cov khoom specification lossis qib.Kub dov hlau yuav tsum dov cov hlau ntawm qhov kub thiab txias, qhov twg txias dov hlau yog ua tiav nyob rau hauv txias txo mills qhov twg cov khoom yog txias tom qab annealing thiab / los yog tempers dov.
Kub Rolled Steel
Kub dov yog txheej txheem zeb uas suav nrog dov cov hlau ntawm qhov kub thiab txias (feem ntau ntawm qhov kub siab tshaj 1700 ° F), uas yog siab dua cov hlau qhov kub ntawm recrystallization.Thaum cov hlau yog siab tshaj qhov kub ntawm recrystallization, nws tuaj yeem tsim thiab tsim tau yooj yim, thiab cov hlau tuaj yeem ua rau ntau qhov ntau thiab tsawg.Kub dov hlau feem ntau pheej yig dua li cov hlau txias vim qhov tseeb tias nws yog feem ntau tsim yam tsis muaj kev ncua sij hawm, thiab yog li ntawd cov hlau tsis tas yuav tsum tau reheating (raws li nws yog nrog txias dov).Thaum cov hlau txias tawm nws yuav ntsws me ntsis yog li muab kev tswj tsawg dua ntawm qhov loj thiab cov duab ntawm cov khoom tiav thaum piv rau txias dov.
Kev Siv: Cov khoom kub dov zoo li kub dov steel tuav yog siv nyob rau hauv vuam thiab kev tsim kho kev lag luam los ua railway lem thiab I-beams, piv txwv li.Kub dov hlau yog siv nyob rau hauv cov xwm txheej uas cov duab meej thiab kev zam tsis tas yuav tsum tau ua.
Txias Rolled Steel
Cold rolled steel yog qhov tseem ceeb kub dov hlau uas tau muaj kev ua haujlwm ntxiv.Cov hlau tau ua tiav ntxiv hauv cov tshuab txo qis, qhov twg cov khoom yog txias (ntawm chav tsev kub) ua raws li annealing thiab / lossis tempers dov.Cov txheej txheem no yuav tsim cov hlau nrog ze dua qhov ntev kam rau ua thiab ntau yam ntawm cov khoom tiav.Lub sij hawm Cold Rolled yog siv yuam kev rau tag nrho cov khoom, thaum ua tau cov khoom npe yog hais txog cov dov ntawm cov ntawv tiaj tus dov thiab cov khoom coil.
Thaum xa mus rau cov khoom lag luam bar, lo lus siv yog "txias tiav", uas feem ntau muaj cov duab txias thiab / lossis tig, sib tsoo thiab polishing.Cov txheej txheem no ua rau cov ntsiab lus siab dua thiab muaj plaub qhov zoo:
Kev kos duab txias ua rau kom muaj txiaj ntsig thiab muaj zog tensile, feem ntau tshem tawm cov kev kho cua sov ntxiv.
Tig tau tshem ntawm qhov chaw tsis zoo.
Sib tsoo nqaim qhov qub me me kam rau ua ntau yam.
Polishing txhim kho qhov chaw tiav.
Tag nrho cov khoom txias muab qhov zoo tshaj plaws saum npoo tiav, thiab zoo dua nyob rau hauv kam rau ua, concentricity, thiab straightness thaum piv rau kub dov.
Cov kab txias tiav lawm feem ntau nyuaj rau kev ua haujlwm nrog ntau dua li kub dov vim muaj cov pa roj carbon ntau ntxiv.Txawm li cas los xij, qhov no tsis tuaj yeem hais txog cov ntawv txias dov thiab cov ntawv kub dov.Nrog rau ob yam khoom no, cov khoom txias dov muaj cov ntsiab lus carbon tsawg thiab nws feem ntau yog annealed, ua rau nws softer dua kub dov ntawv.
Siv: Txhua qhov project uas kam rau ua, qhov chaw saum npoo, concentricity, thiab ncaj yog qhov tseem ceeb.
