12Cr1MoV siab siab boiler rajtau tsim los ntawm thawj 12xm steel (0.5% Cr-Mo-V) mus rau 12x1m (1% Cr-Mo-V) steel los ntawm kev nce cov ntsiab lus Cr.Cov tshuaj muaj pes tsawg leeg ntawm12Cr1MoV Alloy Seamless Steel Tubeyog qhov yooj yim, tag nrho cov ntsiab lus alloy tsawg dua 2%, thiab nws muaj cov txheej txheem zoo heev thiab lub cev muaj zog.Tam sim no, nws tau teev nyob rau hauv seamless steel yeeb nkab qauv rau kev kub siab boiler nyob rau hauv Tuam Tshoj (GB5310-2008).Cov qib steel zoo sib xws tau siv dav hauv txawv teb chaws suav nrog ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Lub Tebchaws Yelemees), thiab lwm yam.
Tam sim no,12Cr1MoV Seamless Steel Yeeb Nkabyog dav siv nyob rau hauv Superheater, header thiab lub ntsiab chav conduit ntawm kev kub siab, ultra-siab siab thiab subcritical fais fab chaw nres tsheb boilers nyob rau hauv tsev thiab txawv teb chaws.Cov hlau no tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thiab boiler hauv Tuam Tshoj txoj kev lag luam fais fab.
Tam sim no,12Cr1MoV Seamless Steel TubeFeem ntau yog siv nyob rau hauv cov nram qab no yam:
(1) Feem ntau yog siv rau cov yeeb nkab superheater, cov yeeb nkab cua, cov yeeb nkab tseem ceeb, cov yeeb nkab reheater thiab lwm qhov ntawm cov khoom siv boiler, tshwj xeeb tshaj yog nyob rau hauv high-pressure thiab ultra-high-pressure boiler, 12Cr1MoVG tsis tshua muaj alloy kub-resistant steel yog dav siv.
(2) Mas siv rau lub ntsiab ncej,] impeller, rotor, fastener (bolt thiab txiv ntseej), lub tog raj kheej, nozzle chamber, lubricating valve, diaphragm thiab ib co hniav ntaub ntawv ntawm chav turbine.
(3) Feem ntau yog siv los txo qhov kub thiab txias ua haujlwm ntawm rotor thiab hniav hauv lub cav roj kub txog li 550 ℃, txhawm rau nthuav dav daim ntawv thov ntawm cov hlau tsis tshua muaj hluav taws kub-resistant hlau hauv lub cav roj.
(4) tuaj yeem siv los tsim cov roj turbine rotor, impeller, fastener thiab lwm qhov chaw nrog kev ua haujlwm kub hauv qab 570 ℃.
(5) Feem ntau yog siv rau kev tsim hluav taws xob cov yeeb nkab, cov khoom siv hluav taws xob thiab lwm cov kav dej kub hauv cov khoom siv tshuaj lom neeg thiab roj av.
