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 ua rau cov cua sov, thaum lub hwj chim zoo ib yam, qhov chaw thauj khoom 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.
Incoloy 800 alloy yog Ni-Fe-Cr alloy siv los tiv thaiv oxidation thiab carbonization. Nws cov ntsiab lus npib tsib xee nce mus txog 32 feem pua, uas ua rau 800 alloy muaj kev tiv thaiv zoo rau chlorine-induced stress corrosion cracking thiab nag lossis daus ntawm σ theem ua rau cov hlau nkig. 800 alloy kuj zoo heev nyob rau hauv uniform corrosion kuj. Nyob rau hauv lub xeev kev kho mob, 800H thiab 800AT muaj zoo heev creep thiab kev nyuaj siab rupture zog. Lub 800 series alloys yeej ib txwm zoo ib yam, tshwj tsis yog tias cov ntsiab lus carbon hauv 800H siab dua me ntsis (0.05-0.10 feem pua), thiab 1.00 feem pua Al ntxiv rau Ti yog ntxiv rau 800AT. 800 alloy feem ntau siv tau txog 593 degree. 800H thiab 800AT feem ntau yog siv ntawm qhov kub siab tshaj 593 degree, uas yuav tsum tau muaj kev xav tau siab rau creep thiab kev nyuaj siab corrosion cracking.
