Zitsulo zopitilira kutentha
Malinga ndi mawonekedwe osiyanasiyana, zitsulo zosakanizika zimagawika zitsulo zotsutsana ndi kukana kwa oxidation monga momwe ma oxidation amagwirira ntchito ndi mphamvu yotentha ndi matenthedwe akuluakulu {{0}
① kukana ma oxide oxide kukana zitsulo zambiri mu kaboni kwambiri wa kaboni kwambiri, monga mtundu wa alungu wa a Austitic, Mfungula, kulumikizana ndi chitola, etc {{5 {{5} komanso kumeta, kotentha ndi kuzizira komanso kuwotcherera {16}
Chitsulo cha antioxide chimagwiritsidwa ntchito pogwira ntchito nthawi yayitali pamtunda wautali, koma mphamvu, etch {{}
② Mphamvu yamafuta amphamvu imatha kugawidwa m'magulu atatu:
{{{0}<0.2%; Cr and Si improve the oxidation resistance of steel; Cr, Mo (W) are soluble in ferrite and enhance the recrystallization temperature, thus increasing the creep limit of the matrix; Cr, Mo, V (Ti) strengthen the dispersion.
Mawonekedwe otetezedwa: kuyamwa kwabwino (95 ~ 1050 digiri) kenako 100
Manambala achitsulo wamba ndi 15 crmo, 12cr1Mov, 25cr2Mova, onjezerani magwiridwe antchito, kutentha kwamphamvu, 550℃mphamvu . mtundu uwu umagwiritsidwa ntchito popanga zomera zamagetsi zokhala ndi ma digirii, zotupa zina, etc {{12 {
B . machitidwe a marntic mphamvu zitsulo ndi: Pansi (wapakati) kaboni, WC {1 {1}%} 4%; Mu zigawo za Aloy zomwe zili ndi, cr yayitali zimagwiritsidwa ntchito kukonza mankhwala a oxidation; Kr, W, mo, v, (ti, nb) ndi zinthu zina zomwe zimapangitsa kuti zinthu zisinthe ndikubala; W, mom amathanso kuchepetsa mkwiyo.
Makhalidwe a kutentha ndi: mankhwala abwino kwambiri + Kutentha kwambiri digiri ya 100 Pamwamba pa Kutentha Kwachitsulo, ndipo moyenera
Chiwerengero chodziwika bwino ndi 1crl3, 2cr13,1crlmov, 1crl2w {{14crl { Kutentha kwake kumatha kukhala pakati pa 55 {{30} ndi 600 digiri, ndi matenthedwe okwera kwambiri kuposa ma 100 digicav, zomwe zili zoyenera kupanga masamba a Turbine, momwemonso Yotchedwa tsamba chitsulo {26}
C {. ndipo ili ndi cr cr, yi teal wamba. Kr, W, Mo; Kr, W, mo ndi ti.
Makhalidwe a kutentha chithandizo ndi: Kutentha kwa njira yothetsera digiri ya 1000 pambuyo pozizira, ndikukhazikitsa mphamvu yolimbitsa thupi Austetitic ndi Diffision Previptated Alsiptated Carbide (4cr14nil4w2w2w2w2w steel) {{12}
Nambala yodziwika bwino ndi 1crl8NI ndi 4crl4Neil4w2w2w2w, ndipo kutentha kwa chitsulo ya chitsulo {{10} kukana {{12}
Kutentha kwa ma antioxidant kutentha kwa 1crl8ti9ti Ultra-High Couler Boiler pansi pa 650 degree, chitoliro champhamvu cha Steam Turbine, chitoliro champhamvu kwambiri
