Kub Rolled Steel vs Cold Rolled Steel
Rolling yog txheej txheem hlau uas siv cov txheej txheem ntawm cov chais los hloov cov duab, txhim kho qhov sib xws, thiab / lossis txhim kho cov khoom siv ntawm cov khoom. Rolled steel encompasses ob lub ntsiab: kub dov steel thiab txias dov hlau, txhua yam qhia txawv cov yam ntxwv haum rau ntau yam kev siv. Kev nkag siab txog qhov tsis sib xws ntawm ob hom no yog qhov tseem ceeb thaum xaiv cov khoom siv hlau tsim nyog rau ib qhov project, vim tias lawv cuam tshuam rau kev ua tau zoo.

Kev Taw Qhia rau Kub Rolled Steel
Kub dov hlauhais txog cov hlau uas tau dhau los ua cov txheej txheem dov ntawm qhov kub siab tshaj nws qhov chaw recrystallization (feem ntau yog 1700 degree F lossis siab dua). Cov txheej txheem no txhim kho cov khoom tsim thiab ua haujlwm tau zoo piv rau cov hlau nyoos, ua kom yooj yim tuav hauv cov txheej txheem tom ntej.
Cov txheej txheem kub dov pib nrog lub voj voos hlau loj uas hu ua billet. Thaum xub thawj, lub billet yog rhuab thiab compressed rau hauv ib tug loj yob. Thaum tseem kub, nws dhau los ntawm ib ntu ntawm cov rotating rollers kom ncav cuag qhov xav tau qhov ntev. Nyob rau hauv daim ntawv hlau ntau lawm, cov dov hlau yog ces raug mob rau hauv coiled yob thiab tso cai rau txias. Rau lwm cov ntawv thov kev tsim khoom, cov khoom ua tiav raug txiav rau hauv cov teev teev thiab ntim raws li.
Qhov zoo ntawm Kub Rolled Steel
Kub dov steel muab ntau cov txiaj ntsig kev tsim khoom, suav nrog:
1. Tus nqi qis: Kub dov hlau feem ntau yog siv nyiaj ntau dua li cov hlau txias txias vim tias yuav tsum tau ua kom txo qis.
2. Txhim kho kev ua haujlwm: Qhov kub siab thaum lub sij hawm kub dov ua rau ntau dua formability thiab yooj yim ntawm shaping rau cov khoom ua tiav.
3. Cov kev ntxhov siab tsawg kawg nkaus: Los ntawm kev ua kom txias txias thaum lub sij hawm kub dov, cov hlau tuaj yeem ua rau nws cov qauv zoo, txo qhov kev ntxhov siab sab hauv.
Kev siv ntawm Kub Rolled Steel
Vim nws txoj kev xav kom qis me ntsis thaum lub caij txias, kub dov hlau feem ntau yog siv rau hauv cov ntawv thov uas qhov kev tswj cov duab tsis tseem ceeb. Common siv muaj xws li:
1. Cov khoom siv ua liaj ua teb
2. Automotive qhov chaw (piv txwv li, ncej thiab log rims)
3. Cov khoom siv tsim kho (piv txwv li, I-beams)
4. Cov khoom siv hauv kev tsheb ciav hlau (xws li cov tsheb ciav hlau thiab cov tsheb ciav hlau)

Kev Taw Qhia rau Cold Rolled Steel
Cold dov hlauyog hais txog kub dov hlau uas tau ua tiav ntxiv los txhim kho nws qhov loj me thiab cov khoom siv kho tshuab. Nyob rau hauv cov txheej txheem txias dov, txias kub dov hlau yog dhau los ntawm cov chais ntxiv ntawm chav tsev kub. Raws li cov khoom siv tsis yog kub thiab malleable, ib qho kev txiav txim siab siab dua yog qhov tsim nyog los tsim nws raws li qhov xav tau. Txawm hais tias cov txheej txheem no yuav siv zog ntau dua thiab kim dua piv rau cov kub dov, nws ua rau muaj kev tiv thaiv zoo dua thiab zoo dua.
Qhov zoo ntawm Cold Rolled Steel
Nyob rau hauv kev sib piv rau kub dov steel, txias dov steel muaj ntau yam txiaj ntsig, suav nrog:
1. Enhanced zog:Cold dov hlautuaj yeem nthuav tawm txog li 20% lub zog ntau dua li kub dov hlau, ua rau nws tsim nyog rau cov ntawv thov kev ntxhov siab.
2. Superior nto finishes: Cov khoom siv thiab cov khoom siv tes ua los ntawm txias dov hlau feem ntau muaj qhov du thiab ci ntsa iab uas tsis muaj xeb thiab nplai.
3. Ntau dua precision: Tsis zoo li kub dov steel, txias dov steel tuav nws qhov ntev tom qab txheej txheem tsim. Cov yam ntxwv no ua rau kev tsim cov khoom muaj meej heev uas yuav tsum muaj tsawg heev kom tsis muaj kev ua haujlwm thib ob.
Kev siv ntawm Cold Rolled Steel
Cold rolled steel pom tau siv ntau zaus hauv cov ntawv thov kom nruj dua kev ua siab ntev thiab ua tiav qhov zoo tshaj plaws. Feem ntau cov khoom thiab cov khoom muaj xws li:
1. Aerospace cov qauv
2. Cov khoom siv hauv tsev
3. Hlau rooj tog
4. Sawb, rods, tuav, thiab ntawv
5. Mechanical Cheebtsam
Qhov sib txawv tseem ceeb ntawm Kub Rolled Steel thiab Cold Rolled Steel
Raws li tau hais, qhov sib txawv ntawm qhov sib txawv ntawm cov hlau kub kub thiab txias dov hlau nyob hauv qhov kub ntawm kev ua haujlwm. Kub dov steel undergoes dov saum toj no cov khoom lub recrystallization kub, thaum txias dov hlau yog dov hauv qab no kub. Ntxiv nrog rau qhov sib txawv tseem ceeb no, muaj ntau qhov sib txawv ntawm ob qho khoom siv, suav nrog:
1. Nto zoo: Kub dov hlau feem ntau muaj cov npoo ntxhib thiab qhov chaw uas yuav tsum tau decarburization lossis lwm yam kev kho mob rau kev siv hauv kev ua haujlwm tom ntej. Conversely, txias dov hlau feem ntau boasts ib tug ci ntsa iab thiab du nto, ua rau nws haum rau tam sim ntawd siv nyob rau hauv ntau lawm.
2. Khoom hardness: txias dov ua rau cov hlau muaj zog dua thiab hardness piv rau cov hlau uas ua los ntawm kub dov.
3. Kev ntxhov siab sab hauv: Kev txhim kho lub zog thiab qhov tawv tawv tau qhia los ntawm cov txheej txheem txias dov kuj ua rau muaj kev ntxhov siab ntau dua. Cov kev ntxhov siab no yuav tsum tau muab tshem tawm ua ntej ua haujlwm ntxiv kom tsis txhob muaj peev xwm warping hauv qhov kawg lossis cov khoom lag luam.
