1. Dab tsi yog 20mog steel yeeb nkab?
20mog yog molybdenum alloy seamless boiler boiler boiler gb / t 5310 thiab tau cais ua tus lej Suav, cua sov {} {tsis kam hlau. Nws lub npe txhais tau tias:
"20": Cov ntsiab lus ntawm cov pa hluav taws xob ntawm kwv yees li 0.17% -0.24% (siab me ntsis dua 15mog, ua rau muaj zog dua);
"MO": 0.40% {- 0.55% molybdenum yog ntxiv rau txhim kho cov siab kub siab;
"G": Boiler -} Tshwj xeeb (thawj zaug ntawm Suav Pinyin rau "Gu").
Nws yog feem ntau siv nyob rau hauv superheaters thiab steab piping hauv high {{0} pa taws cog boilers. Nws ua haujlwm nyob rau hauv qhov kub ntawm 450℃-580 degree, muab cov kub siab tshaj li 15mog.
2. Dab tsi yog cov tseem ceeb ua tau zoo ntawm 20mog?
High - kub lub zog: tensile lub zog ntau dua los yog sib npaug rau 420 MPA, zoo dua li 20G);
Nkag los tiv thaiv: molybdenum inhibits carbide agration, ua rau nws tsis tshua muaj kev puas tsuaj thaum ntev {}-}}} kub kev pab;
Weldability: preheating rau 180 degree- 250 kev kho kom sov (xws li tempering tshav kub (xws li tempering) yuav tsum tau txo qis kev ntxhov siab.
3. Dab tsi yog qhov txawv ntawm 20mog thiab 15mog?
Cov ntsiab lus carbon: 20mog muaj cov ntsiab lus carbon ntau dua (0.17% -0.24% vs {}}} pa's lub zog tab sis me ntsis qis weldability;
Muaj feem xyuam Kub: 20mog muaj qhov kub siab tshaj plaws ntawm 580 degree, thaum 15mog yog haum rau qhov kub qis dua 550 degree;
Tus nqi sib txawv: vim lawv cov muaj pes tsawg leeg zoo sib xws, ob tus kwv tij sib thooj, tab sis 20mog feem ntau siv hauv siab dua- parameter units.
4. Dab tsi yog cov ntawv thov ntawm 20mog? Kev Lag Luam Fais Fab: High {- sov superheaters thiab cov chav dej tseem ceeb rau ultra- siab boilers;
Petrochemical Kev Lag Luam: Siab - kub tawm cov khoom thiab hydrogenation reactor piping;
Cov kev tshwj xeeb: Cheebtsam feem ntau yuav ua rau muaj kev caij cermal (vim nws tau ua haujlwm hnyav ua rau nkees nkees).
5. Kuv yuav tsum xav li cas thaum mus yuav 20mog?
Cov ntaub ntawv pov thawj: Txheeb xyuas cov GB / T 5310-2017-2017 Zoo daim ntawv pov thawj kom ntseeg tau tias cov ntsiab lus molybdenum tau raws li tus qauv.
Yuav Tsum Tau Ua: Ultrasonic Qhov khuam kom nrhiav kom (UT) thiab siab - Tensile Kev Ntsuas Kub Tensile tau pom zoo.
Lwm Txoj Kev: Yog tias qhov ntsuas kub qis dua 450 degree, 15mog yuav suav tau tias txo tus nqi.
