PvQ Hlau Hlau Yog Dab Tsi?
Lub raj kub siab zoo (PVQ) Phaj steel yog siv los ua cov hlab siab siab vim nws cov phiaj tawv me me tseem hu ua chrome Moly steel phiaj?.
Ua ntej kev kuaj xyuas cov khoom ntawm PVQ cov qib kawm, ntawm no yog ob peb cov lus siv los piav txog cov khoom ntawm cov hlau, txhais:
Lub zog:Cov Hlau Thauj Tau Ua Npib . steel muaj zog yog qhov kev ntxhov siab uas xav tau rau cov khoom siv kom tawg {}}
Ceeb toom tsis zoo:theem kev cuam tshuam hlau tuaj yeem nqus tau ua ntej kev kho hniav, ntsuas los ntawm kev cuam tshuam charpy sim .
Ductility:Lub peev xwm ntawm cov khoom yuav tsum ncab ua ntej nws ua tsis muaj zog lossis ntsuas qhov ntev ntawm cov khoom siv ncab tau ua ntej nws tawg.
Cov khoom ntawm cov qib PVQ theem tseem ceeb
Thaum muaj ntau cov qib ntawm PVQ Hlau, Astm A516 thiab ASTM A516 thiab cov AFTM A537 feem ntau yog siv rau kev siv nyiaj siab vim lawv qhov sib npaug ntawm lub zog thiab ductility.
ASTM A516
ASTM A516 yog cov pa roj carbon ntau-rau-nruab nrab ntawm cov roj ntsha uas muaj nyob rau hauv plaub qib sib txawv: 55, 60, 65 thiab {7}70.
Piv rau lwm qib, A516 yog ib qib pvq steel, ua rau nws tsim nyog los tsim cov ntaub ntawv nkhaus ntawm ib qho khoom siv tank lossis boiler.
Kom nce lub zog thaum ua kom muaj ntau cov pa roj carbon monoxes tau ntxiv, xws li cov lus qhia, cov lus qhia hauv kab ntawv hauv qab no.
| ASTM A516 | Qib 55 | Qeb 60 | Qib 65 | Qib 70 |
| Pa roj carbon | 0.18-0.26% | 0.21-0.27% | 0.24-0.29% | 0.27-0.31% |
| Tus kws dai txiv manganese | 0.60-1.20% | 0.60-1.20% | 0.85-1.20% | 0.85-1.20% |
| Phosphorus max | 0.025% | 0.025% | 0.025% | 0.025% |
| Sulphur Max | 0.025% | 0.025% | 0.025% | 0.025% |
| Silicon | 0.15-0.40% | 0.15-0.40% | 0.15-0.40% | 0.15-0.40% |
A516 tuaj yeem muab rau hauv ob qho xwm txheej:
Raws li-rolled:Lub phaj yog muab tsis muaj kev kho cua sov . rolled phaj ntawm kev kho cua sov
Qub lawm:Lub phaj tau txais kev kho cua sov hauv lub phaj yog rhuab rau qhov ntsuas kub thiab txias rau txhua lub sijhawm (
A516 cov qib muaj cov txiaj ntsig zoo thiab lub zog ua kom muaj zog lossis tsis muaj zog ntawm cov khoom siv hauv PV ntawm 516.
Lwm cov qib PVQ
Thaum A516 thiab A537 yog cov qib Pvq thiab tuaj yeem siv ntau daim ntawv thov, lwm cov qhab nia PVQ tuaj yeem siv rau cov kev siv vessel tshwj xeeb.
