Lub nplaim Rockwell Hardness ntawm annealedly carbon hlau feem ntau yog 55 + -3, thiab cov ntawv txias-dov thiab cov ntawv txias feem ntau muaj qhov tuab ntawm 0.1-3 hli thiab dav ntawm 100-2000mm; Ob qho tib si yog ua los ntawm kub-rolled sawb lossis steel phaj. Cov.
CRS yog cov lus luv ntawm lus Askiv txias dov steel, uas yog, cua txias rolled steel. Nws hais txog kev dov cov txheej txheem ntawm cov hlau. Piv txwv li, Q235 tib yam cov roj carbon hlau tuaj yeem muab txias txias, thiab 10 # steel phaj kuj tuaj yeem tuaj yeem dov tau. Nws lub hardness tuaj yeem nyob ntawm tus qauv sib xws raws li cov qauv steel siv. Cov.
Dab tsi yog cov qib ntawm cov ntawv txias-dov-dov dua li Spcc? Cov.
Cov ntawv txias-yog cov tsiaj ntawv luv ntawm cov qauv roj txawv, tseem hu ua cov ntawv txias-dov, thiab qee zaum yuam kev sau ua cov ntawv txias. Lub phaj txias yog ua los ntawm cov qauv carbon txheej txheem steel hlau kub-uas yog ntxiv rau hauv cov hlau nrog cov tuab tsawg dua 4 hli. Cov.
Daim ntawv txias-dov tau muab faib ua: 1/8 nyuaj, 1/4 nyuaj, 1/2 nyuaj thiab tag nrho lub xeev. Feem ntau muaj ob lub ntsiab nyob ntawm hardness nqi: HRB (Rockwell) HV (vickers) raws li hauv qab no: rockwell) hv (vickers) 1/8 nyuaj. Cov.
Pickling Phaj yog lub phaj kub uas tau raug xws li dephosphorization (kev tshem tawm thaum lub ntsej muag kub kom tau txais ib lub phaj steel nrog kev ua tau zoo dua li kub -srods nto. Nws tuaj yeem pom los ntawm nws cov txheej txheem tsim khoom uas nws lub hardness yog kub dov nrog tib qib. Cov.
Muaj qhov tsis muaj qhov sib txawv hauv kev ua kom tawv taub hau ntawm cov khaub thuas txias thiab galvanized. Vim tias galvanized nto tsuas yog plated nrog ib txheej ntawm zinc los ntawm ob peb microns kom txog 20 microns nyob rau substrate. Cov substrates feem ntau txias-dov thiab kub-dov. Lub hardness feem ntau yog nyob ntawm qib ntawm cov khoom, thiab cov qib sib txawv. Cov.
Nqa DC01, DC03 ua piv txwv. DC01 Upper txwv ntawm cov txiaj ntsig lub zog ntawm cov ntawv kom muaj zog 240, tus xov tooj sawv cev rau qib stamping, thiab tus lej loj dua.
Txias-dov daim ntawv yog ua los ntawm kub-rolled coil li cov khoom siv raw, siv nyob rau hauv chav nyob hauv qab no lub recrystallization kub, thiab nws hardness yog li 150hv. Lub tshuab shearing feem ntau yog ua los ntawm cov cuab yeej hlau, nrog lub hardness ntawm HRC55 ~ 58 °, uas tuaj yeem txiav feem ntau ntawm lawv.
