FAQ
01.Dab tsi yog qhov txawv ntawm CCS Qib A thiab Qib B shipbuilding steel?
Qib B yuav tsum muaj kev ntsuam xyuas qhov cuam tshuam ntawm 0℃nrog qhov tsawg kawg ntawm 27 Joules, thaum Qib A tsis muaj qhov yuav tsum tau muaj kev cuam tshuam (tsuas yog xav tau ntawm +20℃). Qib B kuj tseem muaj cov ntsiab lus ntawm manganese tsawg dua (0.80% vs 0.50%) thiab cov ntsiab lus silicon qis dua (0.35% vs 0.50%). Qib B yog qhov zoo dua rau cov qauv tsim kom ntseeg tau tias muaj kev cuam tshuam toughness ntawm nruab nrab kub.
02.Puas yuav tsum tau preheating rau vuam CCS Qib B daim hlau?
03.Kuv yuav xaiv qhov kev kho cua sov dab tsi?
t Tsawg dua los yog sib npaug li 50mm: Raws li -rolled (AR) lossis tswj-rolled (CR) yog haum rau feem ntau cov ntawv thov.
t > 50mm: Normalized (N) los yog TMCP yog yuav tsum tau los ntawm kev faib cov cai los xyuas kom meej txhua yam khoom zoo ib yam los ntawm tag nrho cov thickness.
04.CCS Qib B puas tuaj yeem siv rau dej hiav txwv- mus rau nkoj?
Yog, tab sis nrog kev txwv. CCS Qib B yog qhov cuam tshuam los ntawm 0 degree, ua rau nws tsim nyog rau cov nkoj ua haujlwm hauv cov dej kub thiab dej hiav txwv. Rau cov nkoj taug kev cov dej hiav txwv txias uas qhov kub poob qis dua 0 degree, CCS Qib D (-20 degree) lossis Qib E (-40 degree) yuav yog qhov kev xaiv tsim nyog.
