Cold dov hlau
Cold Rolled Steel yog dab tsi?
Cold dov hlau yog qhov tseem ceeb kub dov hlau uas tau dhau los ntawm kev ua haujlwm ntxiv. Thaum kub dov hlau tau txias lawm, nws yuav rov qab - dov nyob rau hauv chav tsev kub kom ua tau raws nraim qhov ntev thiab zoo dua nto qualities.
Txias "dov" steel feem ntau yog siv los piav txog ntau yam ntawm cov txheej txheem ua tiav, txawm hais tias technically "txias dov" tsuas yog siv rau cov nplooj ntawv uas tau txais compression ntawm cov menyuam. Cov ntaub ntawv hlau uas rub, xws li cov tuav lossis cov raj, yog "kos," tsis dov. Lwm cov txheej txheem txias txias muaj xws li tig, sib tsoo, thiab polishing- txhua qhov yog siv los hloov cov khoom kub kub uas twb muaj lawm rau hauv cov khoom ua kom zoo dua qub.
DC01 yog cov pa roj carbon tsawg thiab txias dov steel siv, yog tus qauv kev lag luam European tus qauv EN 10130 tus qauv, sib npaug rau sab hauv gb GB699 tsim cov khoom zoo carbon steel 10 # steel, cov ntsiab lus carbon yog kwv yees li 0.10%, lub hom tuaj yeem siv rau kev ua haujlwm yooj yim, xws li khoov, embossing thiab kos duab.
DC03 qib rau txhua yam ntawm deformation muaj kev sib sib zog nqus zoo heev. Lub hom phiaj yog tsim rau kev sib sib zog nqus nqus, xws li kev luam ntawv nyuaj molding.
DC04 qib yog ib qho ntawm DC qib ntawm kev sib sib zog nqus nqus hlau series. Lub hom yog haum rau txhua hom deformation, muaj qhov zoo sib sib zog nqus nqus. Haum rau kev tsim cov kev xav tau siab ntawm DC04.
DC05 qib rau txhua yam ntawm deformation muaj kev sib sib zog nqus zoo heev. Qhov sib sib zog nqus kos duab zoo yog tsim rau cov kev xav tau siab dua.
DC06 qib rau txhua yam ntawm deformation muaj kev sib sib zog nqus zoo heev. Daim duab sib sib zog nqus tshwj xeeb yog tsim rau kev tsim cov kev xav tau zoo tshaj plaws, yog siab - zoo, qis decarburization ntawm IF steel, titanium alloy. Qhov no yog vim li cas DC06 qhov nyuaj, tshwj xeeb tshaj yog tsim rau kev sib sib zog nqus nqus thiab ncab, xws li phab ntsa, lub lauj kaub roj thiab hauv pem teb.
DC07 qib rau txhua yam ntawm deformation muaj kev sib sib zog nqus zoo heev. Hom kev sib sib zog nqus tob tob no rau molding qib siab xav tau, yog siab - zoo, qis decarburization ntawm IF steel, titanium alloy. Qhov no yog vim li cas DC07 tshwj xeeb tshaj yog tsim rau kev sib sib zog nqus nqus thiab tensile hardware, xws li phab ntsa, lub lauj kaub roj thiab hauv pem teb.

FAQ
1. Dab tsi yog txias -rolled steel? "Cold Rolled Steel" txhais li cas?
Txias- dov steel yog hais txog cov hlau ua tiav los ntawm cov txheej txheem dov ntawm chav tsev kub. Nws muaj qhov ua tiav qhov siab, qhov siab qhov tseeb, thiab cov khoom siv kho tshuab zoo heev, thiab feem ntau yog siv rau hauv tsheb, khoom siv hauv tsev, rooj tog zaum, thiab cov tshuab tsim khoom lag luam.
2. Dab tsi yog qhov txawv ntawm txias-rolled steel thiab kub-rolled steel?
Txias dov yog ua tiav ntawm chav tsev kub, ua rau muaj qhov tseeb dua qhov tseeb thiab lub ntsej muag smoother, haum rau cov khoom uas xav tau kev pom zoo thiab qhov tseeb. Kub dov yog ua tiav ntawm qhov kub thiab txias, uas ua rau muaj zog dua, tab sis lub rougher nto. Txias- dov steel feem ntau kim dua li kub- dov steel.
3. Dab tsi yog qee cov qib ntawm txias-rolled steel?
Cov qhab nia sib txawv hauv cov txheej txheem sib txawv suav nrog:
EU / EN cov qauv: DC01, DC03, DC04, DC05, DC06
DIN cov qauv: St12, St13, St14
JIS Japanese qauv: SPCC, SPCD, SPCE, SPCF, SPCG
ASTM Asmeskas cov qauv: A1008, A1011
4. Puas tuaj yeem txias- dov steel siv rau kev kos duab sib sib zog nqus?
Yog lawm, tab sis cov qib yuav tsum raug xaiv raws li.
Piv txwv li: DC01 yog haum rau kev sib sau, DC03 rau nruab nrab forming, thiab DC04/05/06 rau kev sib sib zog nqus nqus thiab ultra- kos duab tob.
