Hauv qab no yog kev tsom xam dav ntawm "S460ML z35 Hollow tshooj" steel hlau, ua ke nrog cov European cov qauv, kev ua tau zoo, thov kev txheeb xyuas thiab kev sib piv:
1. Cov ntsiab lus tseem ceeb thiab cov qauv
Lub npe daws teeb meem:
S460ML: High - Lub zog zoo {{2} nplej cov qauv hlau hauv European txheem (thiab 10025-4).
S: Txheej txheem hlau
Thaum lub thickness yog tsawg dua los yog sib npaug rau 16 hli, qhov tsawg kawg yog 460Mpa.
M: Thermo - tshuab rauj ceev, uas tau hais cov nplej los ntawm cov kev tswj hwm dov thiab tswj cov txheej txheem txias;
L: Tsawg {{- kub} kub qhov xav tau (cuam tshuam lub zog loj dua los yog sib npaug ntawm 27 xyoos).
Z35: Cov qib kev ua tau zoo nyob rau hauv lub thickness kev taw qhia, nrog kev txo thaj chaw ntau dua los yog sib npaug rau Lamellar kua muag (xws li z- kev ntxhov siab ntawm welded pob qij txha).
Tus qauv tiav:
EN 10210 (kub {{{{{{}} tsim welded hollow profiles) lossis en 10219 (txias} Koj xa mus rau en 10025-4 raws li cov khoom siv hauv paus qauv.
2. Tshuaj lom neeg ua haujlwm
Txhawm rau kom muaj zog, kev nruj thiab weldability, cov muaj pes tsawg leeg tau tswj hwm:
Cov pa roj carbon (C tsawg dua li lossis sib npaug rau 0.16%): Txo kev ua kom tawv nqaij tawv thiab txhim kho weldability.
Tsawg sulfur thiab phosphorus (s tsawg dua los yog sib npaug rau 0.005%, txo qis dua lossis muaj sib npaug, kom z {{{} kub todlight.
Microalloying: Ntxiv Niobium (NB), Vanadium (V), thiab titanium (ti) kom rov qab cov nplej thiab txhim kho lub zog.
Feem ntau tivthaiv ntau (WT%):
| Ntsiab lus | C | Si | Mn | P | S | Nb + v + ti |
| Zoo siab | Tsawg dua los yog sib npaug rau 0.16% | Tsawg dua los yog sib npaug rau 0.60% | Tsawg dua los yog sib npaug rau 1.70% | Tsawg dua los yog sib npaug rau 0.025% | Tsawg dua los yog sib npaug rau 0.005% |
Tsawg dua los yog sib npaug rau 0.22% |
3. Cov Cuab Yeej Siv Cov Tshuab thiab Kev Xav Tau
Kev tswj nruj kev sab hauv lub cev hauv en 10160 s3160 S3E4 thiab tseem siv tau los thauj - cov kabmob qauv qauv
| Performance index | Yuav tsum muaj tus nqi | Hais lus |
| Paib lub zog (rov qab) | Ntau dua los yog sib npaug rau 460 mpa (tuab tsawg dua lossis sib npaug rau 16 hli) | Lub zog me me txo qis raws li cov tuab nce (piv txwv li, 40mm tuab ntau dua lossis sib npaug rau 430mpa). |
| Lub zog tensile (RM) | 540-720 mpa | Qhov sib npaug ntawm cov zog siab thiab muaj zog zoo |
| Elongation (a) | Ntau dua los yog sib npaug rau 17% | gauge ntev 5.65 evas |
| Tsawg - kub cuam tshuam toduagness | - 50 Qib cuam tshuam lub zog loj dua los yog sib npaug rau 27J (Charpy V-Itch) | ua kom muaj peev xwm tiv thaiv brittle bracture hauv ib puag ncig txias heev |
| Lub z - kev ua haujlwm | Txo thaj chaw ntau dua lossis sib npaug rau 35% (Z35 qib) | tswj los ntawm ultra -} qis sulfur (tsawg dua los yog sib npaug rau 0.005%) |
| Qhov thaiv kom muaj | En 10160 s3e4 thiab sab saud | Kev tsis zoo sab hauv yog cov tswj hwm nruj me ntsis thiab nws yog qhov haum rau load - cov kabmob qauv qauv |
4. Daim ntawv thov tseem ceeb
Tus qauv ntawm cov ncej qaum polar thiab thaj tsam alpine
Xws li Arctic nkoj, tsawg {{- cov choj kub} kub} kub tev (tseem tswj kev nruj (tseem tswj kom muaj kev nruj ntawm -50 degree)
Hnyav - Luag Haujlwm Welded Tus Qauv
Marine platform nodes, siab xa xov ntawm hydroGower chaw nres tsheb, thiab kab thiab kab ke siab nce vaj tse (nrog lub siab ua kom yooj yim los kua muag).
Zog thiab Cov Khoom Siv Khoom Siv
Liquefied natural gas (LNG) storage tanks and gas transmission pipelines (with low-temperature resistance and pressure-bearing requirements).
Lub ntsiab
S460ML Z35 Hollow profile yog qhov siab-} Kev ua yeeb yam welded qauv raj hauv qab European tus qauv. Nws ua tiav tau zoo - nplej qauv los ntawm kev siv tshuab kub rolling txheej txheem. Ultra - Qhov kub tsis muaj qhov kub ntawm {10℃thiab cov qib z35 tsis kam lees cov kua muag yog nws cov ntsiab lus zoo. Nws yog siv rau cov xwm txheej uas muaj kev xav tau siab heev rau cov khoom siv cov khoom siv, xws li cov roj av engineering, thiab zoo}}} Rose tsev. Piv nrog cov qauv txheej txheem tib yam siv hlau, nws ua ke ua ke lub zog siab thiab qis - kub raws. Piv nrog quenched thiab tempered high- lub zog hlau, nws cov kev ua tau zoo tshaj plaws nyob rau hauv cov nqi tswj tau zoo heev.
