Cov chaw tsim khoom puas tuaj yeem muab cov qauv dawb ntawm DC03 kauj?
A: Feem ntau cov chaw tsim khoom tuaj yeem muab cov qauv dawb, tab sis tus neeg yuav khoom feem ntau yuav tsum tau them tus nqi thauj khoom kom yooj yim rau kev kuaj xyuas cov khoom zoo.
Dab tsi yog qhov cuam tshuam ntawm grain loj ntawm DC03 kauj ntawm nws qhov kev ua tau zoo?
A: Ib qho loj npaum li cas zoo heev yuav ua rau cov khoom muaj zog, cuam tshuam rau vuam thiab kev ua haujlwm; tsim nyog nce cov qoob loo tuaj yeem txo cov tawv nqaij thiab txhim kho cov khoom siv plasticity thiab weldability.
Puas yog DC03 coil xav tau kev kho cua sov tom qab stamping?
A: Feem ntau, cov khoom siv stamped tsis xav tau kev kho cua sov, vim tias lawv cov khoom siv kho tshuab ua tau raws li qhov yuav tsum tau ua. Rau siab -precision los yog tshwj xeeb load- cov khoom siv bearing, annealing tuaj yeem siv los tshem tawm cov kev ntxhov siab.
Yuav ua li cas deg corrosion ntawm DC03 coil yuav tsum tau ua?
A: Tsawg corrosion tuaj yeem raug tshem tawm los ntawm kev sib tsoo lossis pickling; Txawm li cas los xij, corrosion hnyav tuaj yeem cuam tshuam rau cov hlau thickness thiab lub zog. Nws raug nquahu kom ntsuas thiab txo qis cov kauj lossis hloov nws kom tsis txhob cuam tshuam cov khoom tiav.
Dab tsi yog qhov sib txawv ntawm DC03 kauj thiab DC04 kauj? A: DC04 muaj lub zog qis zog (tsawg dua los yog sib npaug rau 210MPa) thiab siab dua elongation tom qab tawg (Ntau dua lossis sib npaug rau 38%), ua rau nws muaj ntau tshaj li DC03. DC03 yog qhov tsim nyog rau nruab nrab- nyuaj molding, thaum DC04 tuaj yeem ua cov txheej txheem ua haujlwm nrog cov kev xav tau ntau dua deformation.
