Cov khoom sib piv: 304, 321, 310S, Incoloy800 thiab Ceramic rhaub Tubes
Muaj siab- kub tubular tso cua sov txais ntau cov ntaub ntawv sheath npog zoo tib yam stainless hlau, siab -kub stainless hlau, npib tsib xee-raws li alloy thiab cov ntaub ntawv ceramic, nrog rau txhua qib muaj qhov tshwj xeeb kub hloov pauv thiab cov yam ntxwv ua haujlwm. Kev xaiv cov khoom dig muag yam tsis muaj kev sib piv ua haujlwm yuav ua rau cov nqi khib nyiab lossis qhov kub tsis txaus. Kev txheeb xyuas cov khoom zoo thiab cov xwm txheej uas siv tau tuaj yeem muab qhov kev xaiv raug rau qhov siab -kub cua sov cov dej num, thiab cov ntaub ntawv ua haujlwm ntawm cov thermocouple tuaj yeem txheeb xyuas qhov sib txawv ntawm txhua yam khoom hauv qhov sib xws.
304 stainless hlau yog tus nqi tshaj plaws - cov khoom siv yooj yim siv rau kev ua haujlwm kub hauv qab 450℃. Cov pa roj carbon monoxide no muaj qhov sib npaug ntawm kev ua haujlwm thiab kev tiv thaiv corrosion ntawm qhov nruab nrab thiab qis, nrog tus nqi qis thiab siv dav rau cov cuab yeej ziab khaub ncaws thiab qis - cua sov cua sov. Cov kev ua haujlwm tsis zoo yog pom tseeb hauv qhov kub siab - qhov chaw kub: tsis zoo siab - kub oxidation tsis kam, yooj yim deg tev thiab grain ciam corrosion saum toj no 450 degree, kiag li tsis tuaj yeem hloov mus rau nruab nrab thiab ultra-cov txheej txheem kub kub.
321 stainless hlau yog optimized rau nruab nrab- kub qhov xwm txheej mus txog 600 degree, nrog cov ntsiab lus zoo hauv kev tiv thaiv -intergranular corrosion kev ua tau zoo. Cov khoom titanium ntxiv rau hauv cov khoom siv mis kho cov pa roj carbon atoms, inhibits siab -kub carbide nag lossis daus ntawm cov ciam teb nplej, thiab daws qhov sib txawv micro- tawg tsis ua haujlwm ntawm cov hlau tsis zoo tib yam nyob rau hauv thermal cycling. Nws yog qhov tsim nyog rau nruab nrab - cov khoom siv cua sov nrog kev pib ua haujlwm thiab kaw thiab pom tseeb qhov hloov pauv, tab sis qhov siab - kub oxidation kuj tseem tsis txaus rau kev ua haujlwm siab tshaj 500℃rau kev ua haujlwm ntev -.
310S stainless hlau yog lub hauv paus siab - cov khoom kub resistant rau kev lag luam ultra- kub kub, ruaj khov ua haujlwm kub txog li 800℃. Lub siab chromium-nickel alloy qauv tsim ib ntom ntom tiv thaiv- oxidation zaj duab xis ntawm qhov kub thiab txias, tiv taus huab cua oxidation thiab thermal yaig. Tus nqi sib npaug thiab kev ua tau zoo ua rau 310S yog cov khoom siv dav tshaj plaws rau 500-800℃siab-kub qhov cub, tshuab ziab khaub ncaws thiab cua sov tshuab, dhau los ua cov khoom siv yuav tsum tau ua rau txhua qhov kev lag luam ntau tshaj 500℃.
Incoloy 800 npib tsib xee-raws li alloy yog siab -kawg customized khoom rau siab heev- kub ua hauj lwm kub mus txog 850℃. Qhov sib txawv ntawm cov khoom siv hlau tsis muaj steel cia siab rau saum npoo los tiv thaiv- oxidation zaj duab xis, npib tsib xee-raws li cov alloys muaj qhov siab tshaj -kub creep tsis kam thiab cov qauv ruaj khov, tsis muaj cov qauv softening thiab mus tas li deformation nyob rau hauv ntev - lub sij hawm ultra- kub load. Nws feem ntau yog siv rau kev ua haujlwm siab -cov cuab yeej muaj tseeb uas xav tau ntev- lub sij hawm tsis muaj kev cuam tshuam siab - qhov kub thiab txias kev ua haujlwm thiab cov txheej txheem ruaj khov nruj.
Ceramic cua sov raj yog tshwj xeeb rau ultra- siab heev- qhov kub thiab txias txog li 1200℃. Cov ntaub ntawv hlau yuav raug oxidation hnyav thiab cov txheej txheem tsis ua haujlwm siab tshaj 850 degree, thaum siab - cov ntaub ntawv purity ceramic muaj ultra- kub tsis kam, zoo rwb thaiv tsev kev ua tau zoo thiab tshuaj inertness. Ceramic tubes tswj cov cua sov ua haujlwm ruaj khov hauv ultra- qhov kub thiab txias qhov cub thiab cov khoom siv thermal tshwj xeeb, rhuav tshem qhov ntsuas kub ntawm cov hlau cua sov.
Cov khoom siv hierarchical sib piv raws li qhov kub thiab txias yog qhov tseem ceeb ntawm - qhov kub thiab txias xaiv. Qhov tseeb ntawm cov khoom siv kom tsis txhob muaj kev ua haujlwm pov tseg thiab kev ua siab ntev tsis txaus. Professional material selection schemes combined with graded watt density control and thermocouple temperature monitoring can achieve optimal operational performance and economic benefits for high-temperature heating systems.
