Kev tsim kho cov khoom siv hluav taws xob kheej kheej rau kev lag luam cia.
Kev loj hlob ntawm hnyav- cov tshuaj chemical reactors.
Yuav tsum tau kuaj xyuas dab tsi rau P690Q?
Cov kev tshuaj ntsuam xyuas muaj xws li tshuaj ntsuam xyuas, ntsuas tensile, kuaj qhov cuam tshuam, thiab kuaj ultrasonic. Rau cov ntawv thov siab, ntxiv tsis yog -kev sim ua kom puas tsuaj thiab ntawv pov thawj yuav tsum tau. TS EN 10025-6 Kev ntsuas yuav tsum tau ua kom ntseeg tau tias kev ua raws cai thiab kev nyab xeeb.
P690Q ua haujlwm li cas ntawm qhov kub thiab txias?
P690Q ua tau zoo heev ntawm qhov kub thiab txias vim nws quenched thiab tempered microstructure. Nws tuav cov kev cuam tshuam zoo thiab tiv thaiv cov pob txha tawg, ua rau nws tsim nyog rau kev siv txias - cheeb tsam xws li offshore platforms thiab Northern infrastructure project.
Thickness cuam tshuam li cas P690Q cov khoom?
Raws li thickness nce, yam tsawg kawg guaranteed tawm los thiab tej yam khoom yuav txo me ntsis. Cov phaj tuab kuj xav tau kev tswj cov vuam nruj dua thiab siab dua qhov kub ua ntej. Cov neeg tsim qauv yuav tsum xav txog qhov tuab -Txoj kev sib txawv ntawm cov khoom sib txawv tau teev tseg hauv EN 10025-6.

1. P690Q steel yog dab tsi?
P690Q yog lub siab - lub zog steel qauv tau teev tseg hauv EN 10025-6. Tus "P" qhia txog lub hom phiaj siab, "690" yog hais txog qhov tsawg kawg nkaus tawm lub zog hauv MPa, thiab "Q" txhais tau tias quenched thiab tempered. Nws yog tsim los rau kev siv lub luag haujlwm hnyav uas xav tau lub zog siab, toughness, thiab weldability zoo raws li qhov xav tau kev pabcuam.
2. Tus qauv tswj hwm P690Q steel li cas?
P690Q tau teev tseg raws li European tus qauv EN 10025-6, uas npog siab -yield-strength structural steels nyob rau hauv lub quenched thiab tempered mob. Cov txheej txheem no txhais cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg txwv, cov khoom xa tuaj, thiab cov kev xeem yuav tsum tau ua kom ntseeg tau zoo thiab ua haujlwm zoo.
3. Qhov siab tshaj carbon sib npaug (CEV) ntawm P690Q yog dab tsi?
Qhov siab tshaj plaws carbon sib npaug tus nqi (CEV) rau P690Q feem ntau txwv rau ib ncig ntawm 0.65, nyob ntawm thickness. Kev tswj hwm CEV pab ua kom muaj peev xwm weldability thaum tuav lub zog siab. Tsawg CEV qhov tseem ceeb txo qhov kev pheej hmoo ntawm qhov txias txias thaum vuam.
4. Dab tsi thickness ntau yog muaj rau P690Q?
P690Q daim hlau feem ntau muaj nyob rau hauv cov thickness xws li los ntawm ob peb millimeters mus txog 150 hli, nyob ntawm tus tsim cov hlau. Cov cuab yeej cuab yeej cuab tam sib txawv me ntsis nrog cov tuab, thiab cov neeg yuav khoom yuav tsum paub meej tias muaj thiab ua raws li qhov tshwj xeeb thickness ntau yam.
5. P690Q puas tuaj yeem tsim txias?
Cold forming ntawm P690Q yog ua tau tab sis txwv vim nws lub zog siab. Loj dua dabtsi yog khoov radii yuav tsum tau muab piv rau qis dua - lub zog steels. Kev deformation txias heev tuaj yeem ua rau tawg lossis poob ntawm qhov tawv, yog li kev tsim cov haujlwm yuav tsum ua raws li cov chaw tsim khoom pom zoo thiab cov qauv tsim nyog.
6. P690Q puas tuaj yeem raug nplaim taws txiav lossis txiav ntshav?
Yog lawm, P690Q tuaj yeem yog nplaim taws txiav lossis txiav ntshav, tab sis cov txheej txheem tsim nyog yuav tsum ua raws. Preheating thiab tswj cua txias yog pom zoo rau cov phaj tuab kom tsis txhob muaj ntug tawg. Txiav ntug tej zaum yuav xav tau kev sib tsoo ua ntej vuam kom ntseeg tau tias muaj suab nrov pob qij txha.
