Q370R Siab Hlais Hlua Hlau Hlau

 

Q370r yog ib qib tshwj xeeb ntawm cov phaj steel siv hauv kev tsim cov boilers thiab cov hlab ntsha siab. Nws yog tus yam ntxwv los ntawm nws lub zog siab, kev nruj heev, thiab weldability, ua kom nws haum rau kev siv nrog kev kub siab thiab kub. Cov hlau feem ntau yog ib txwm ua thaum lub sijhawm kev tsim khoom thiab undergoes ultrasonic kuaj kom paub tseeb tias qhov zoo.

Q370r steel phaj yog boiler thiab siab hlab ntsha phaj.
Cov Qauv Txheej Txheem Executive: GB713.
"Q" sawv ntsug rau kev paib muaj zog muaj zog (MPA), thiab r sawv rau cov hlab ntsha.
Tus txheej txheem qib siab yog 15mnnbr.

Petrochemical Kev Lag Luam: Nyob rau hauv hydrogenation reactors, q370 daim hlau uas withst nrho cov hydrogen siab ntawm 20mpa thiab qhov kub ntawm 350 degree. Lawv cov hydrogen corrosion yog 30% siab dua xyoo 16mnr, thiab lub neej pabcuam lub neej yog txuas ntxiv rau ntau tshaj 15 xyoos.

Nuclele Found: The reactor pressure vessels of nuclear power plants adopt this material. Under the working conditions of 300°C and 15.5MPa, after 100,000 hours of service verification, the creep rupture strength retention rate is >90%, thiab nws muaj hluav taws xob hluav taws xob zoo.

Kev lag luam fais fab: Q370r steel daim hlau tau siv nyob rau hauv lub nruas ntawm fais fab nroj tsuag boilers. Ntawm qhov kub ntawm 540 degree, ntev- lub zog ncav cuag 220mpa, uas yog ob zaug ntawm Q245R steel daim hlau, ntsib cov kev cai ntawm cov kev xav tau.

Cov Machinery hnyav: Cov ntaub ntawv no yog siv rau kev kub siab - bearing cov khoom siv ntawm cov xovxwm loj thiab cov khoom siv hydraulic. Nyob rau hauv lub zog ruaj khov, lub neej qaug zog tau nce los ntawm 50%, thiab qhov cuam tshuam tsis kam ua tau raws li qhov yuav tsum tau ntawm API 620 tus qauv.

 

 

Qhov Zoo

Siab dua muaj zog dua Q345R, nrog kev ua tau zoo ntawm tus nqi, tsim nyog rau hloov cov khoom siv txawv teb.

Cov tshuab ua kom zoo los ntawm microalloying (NB / V / ti) txhawm rau txhim kho qis qis - kub nruj.

 

TSHAJ TSHAJ

Ntsuab Smelting: Txo cov roj carbon sib npaug (CEQ) thiab txhim kho vuam ib puag ncig ua si.

Ntsej Muag ntse Tshaj Tawm: tau txais i -}} pab tau ultrasonic kev sim ultrasonic txhawm rau txhim kho kev lees paub tus nqi.

 

Cov Ntaub Ntawv Pom Zoo Xaiv

Q370r yog qhov zoo rau nruab nrab- kub siab, qis} kub, tab sis nruj zog ua haujlwm nrog kev tsim nyog.

Rau cov tsis muaj zog dua (xws li> 400 degree), nws tuaj yeem hloov kho mus rau 18mnmonbr lossis 13mnnimor.
