Dab tsi yog qhov cuam tshuam ntawm qhov chaw thauj khoom ntawm cov cua sov xaim ntawm cov cua sov hlau
Qhov saum npoo ntawm cov cua sov xaim yog hais txog tus nqi hluav taws xob sib koom los ntawm cov cua sov xaim hauv ib cheeb tsam, cim nrog lub cim ω, thiab chav tsev yog W / cm2.
Rau qhov kub thiab txias tsis kam rau cov cua sov, thaum lub hwj chim zoo ib yam, qhov chaw thauj khoom tau raug xaiv ntau dua, uas txhais tau hais tias qhov loj ntawm cov hluav taws xob xaiv hluav taws xob tuaj yeem me dua thiab cov khoom siv tau txais kev cawmdim. Txawm li cas los xij, qhov kev thauj khoom nto yog inversely proportional rau lub neej kev pab cuam ntawm cov cua sov hlau. Yog tias qhov chaw thauj khoom raug xaiv siab dhau lawm, lub neej kev pabcuam yuav tsis tsuas yog txuag cov ntaub ntawv tab sis cov ntaub ntawv pov tseg. Yog li ntawd, kev xaiv kom raug ntawm qhov chaw thauj khoom yog qhov tseem ceeb rau kev siv cov khoom siv electrothermal.
Kev xaiv ntawm qhov chaw thauj khoom yog cuam tshuam nrog cov khoom siv hluav taws xob cua sov, kev qhia tshwj xeeb, qauv, kev ua haujlwm kub, thiab cov cua kub dissipation. Nws kuj tseem cuam tshuam nrog cov huab cua nyob ib puag ncig cov cua sov hlau, cov khoom siv ntawm cov khoom txhawb nqa, thiab qhov zaus ntawm cua sov thiab cua txias thaum siv. Qhov tso cai saum npoo ntawm cov cua sov hlau cov ntsiab lus siv nyob rau hauv industrial resistance furnaces thiab civil electric heaters yog txawv heev vim siv sib txawv. Yog li ntawd, nws yog tsis yooj yim sua kom muab ib tug universally siv tus nqi.
Kev kho annealing ntawm 800 alloy feem ntau yog nyob nruab nrab ntawm 982-1038 degree , thiab lub hom phiaj tseem ceeb yog los kho cov nplej. Kev kho cua sov ntawm 800H thiab 800AT feem ntau yog ua los ntawm 1121-1177 degree . Ntxiv nrog rau lub hom phiaj ntawm softening cov khoom, lwm yam yog kom loj hlob grain ntawm cov khoom thiab txhim kho cov creep kuj thiab kev nyuaj siab puas ntsoog kev ua tau zoo. Inconel600 muaj lub zog zoo heev thiab kev ua haujlwm yooj yim. Nws yog tsuas yog siv nyob rau hauv corrosive ib puag ncig. Nws muaj oxidation kuj nyob rau hauv ib puag ncig mus txog 1177 degrees, tshav kub thiab corrosion resistant alloys, thiab muaj zoo kuj rau intergranular corrosion, kev nyuaj siab corrosion cracking thiab kub halogen corrosion. ; Anti-oxidation kev ua tau zoo, kub thiab txias ua kev ua tau zoo, tsis tshua muaj kub txhua yam kev ua tau zoo, txias thiab kub qaug zog ua haujlwm. Nws muaj lub zog siab ntawm 650 degree, zoo formability thiab vuam yooj yim. Feem ntau siv nyob rau hauv chav cav, dej rhaub, nuclear fais fab nroj tsuag txias; caustic soda thiab VCM ntau lawm; pulp thiab ntawv kev lag luam.
(1) Raws li ASME tus qauv, nws muaj lub zog tsim muaj zog thaum thov ntawm 899 degree;
(2) Lub raj siv tau ntawm qhov kub thiab txias hauv qab 982 degree;
(3) Tseem muaj oxidation tsis kam ntawm 1038 degree;
(4) Ua rau chloride ion corrosion.
Daim ntawv thov feem ntau ntawm 800 alloy yog cov ntawv siv kub kub, xws li cov khoom siv hluav taws xob, petrochemical hloov kho, hydrocracking yeeb nkab fittings, superheated chav kho cov cuab yeej hauv cov pa hluav taws xob thiab cov chaw tsim hluav taws xob nuclear. Cov ntsiab lus siab ntawm chromium thiab npib tsib xee ua rau 800 series alloys muaj kev tiv thaiv zoo rau oxidation thiab carbonization.
