Mu makina opangira moto ndi zonyamulira zamafakitale otentha kwambiri,ma rollers a silicon carbide (SiC)Ndi zinthu zapamwamba kwambiri zomwe zimagwira ntchito bwino kuposa ma rollers achikhalidwe a alumina ceramic ndi alloy. Opangidwa kuti azipirira kutentha kwambiri, kupsinjika kwa makina ndi mlengalenga wowononga wa ng'anjo, amapereka kulimba kwapadera, kukhazikika kwa mawonekedwe ndi kukana kuwonongeka, zomwe zimapangitsa kuti akhale zida zofunika kwambiri pa ma rollers amakono ndi mizere yopanga. Kwa opanga padziko lonse lapansi omwe akufuna kuchepetsa nthawi yogwira ntchito, kuchepetsa ndalama zosamalira ndikuwonjezera mtundu wa malonda, ma rollers a SiC ndi chisankho chabwino kwambiri pa ntchito zotentha kwambiri.
Ma Silicon carbide rollers amagwiritsidwa ntchito kwambiri m'mafakitale ofunikira kwambiri. Makamaka, amagwira ntchito m'makampani opanga zinthu zadothi, amathandizira kupanga matailosi, ziwiya zaukhondo ndi ziwiya za patebulo m'malo oyaka moto mu uvuni pa kutentha kwa 1350℃ -1450℃, amakhala owongoka popanda kupindika kapena kuipitsidwa kuti achepetse zolakwika za malonda. Ndi ofunikanso popanga magalasi, kunyamula magalasi athyathyathya ndi magalasi bwino panthawi yopopera ndi kupanga kuti asakhwime. Ntchito zina zofunika kwambiri zimaphatikizapo kutentha kwa zitsulo zonyamula zitsulo zolemera, komanso gawo latsopano la mphamvu pa ma electrode a batri a lithiamu-ion ndi sintering ya ceramic yamagetsi, chifukwa cha zinthu zawo zoyera komanso zosadetsa.
Pali mitundu iwiri ya SiC roller yomwe imagwirizana ndi mafakitale omwe ali ndi kusiyana kwakukulu: SiC yobwezeretsedwanso (RSiC) ndi SiC yolumikizidwa ndi reaction-bonded (RBSiC), iliyonse yopangidwa kuti igwirizane ndi mikhalidwe inayake yogwirira ntchito.
Ma SiC Roller opangidwanso amapangidwa pogwiritsa ntchito kutentha kwambiri popanda gawo lomangirira, zomwe zimapangitsa kuti SiC ikhale yoyera. Amakhala ndi kutentha kwambiri kwa nthawi yayitali mpaka 1600℃, kukana kutentha kwambiri komanso kuipitsidwa konse, oyenera kugwiritsa ntchito zinthu zadothi zapamwamba, zipangizo zamagetsi ndi mphamvu zatsopano komwe kuyera ndi kulekerera kutentha kwambiri ndikofunikira. Ali ndi mphamvu yochepa yamakina koma kukhazikika kwa kutentha kwambiri sikunafanane.
Ma Reaction-Bonded SiC Rollers amapangidwa ndi gawo laling'ono lomangirira la silicon, lomwe limapereka kuchuluka kwakukulu, mphamvu yamphamvu yamakina komanso magwiridwe antchito abwino onyamula katundu wolemera. Amapangidwira kugwiritsidwa ntchito kwa nthawi yayitali pa 1350℃-1450℃, kutentha kofala kwambiri mu uvuni, ndi otsika mtengo komanso osawonongeka kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri pa matailosi a ceramic a tsiku ndi tsiku, magalasi wamba komanso mizere yonse yopanga zitsulo.
Mitundu yonse iwiri ya ma roller a SiC ili ndi ubwino waukulu: kusintha pang'ono kutentha kwambiri, kukhuthala kwamphamvu kwa okosijeni ndi kukana dzimbiri, komanso moyo wautali wa ntchito kuposa ma roller achikhalidwe, zomwe zimachepetsa ndalama zosinthira ndi zogwirira ntchito kwambiri.
Timapereka ntchito zonse za SiC roller zomwe zimagwirizana ndi zosowa zanu zenizeni. Gulu lathu limakuthandizani kusankha pakati pa magiredi obwezeretsanso ndi ogwirizana ndi reaction kutengera kutentha kogwirira ntchito, katundu ndi bajeti, kenako limasinthira miyeso yofunika kwambiri: mainchesi akunja/mkati, kutalika konse komanso kogwira ntchito, kuphatikiza kukonza bwino malekezero kuphatikiza khosi, mipata ndi malekezero oyenda kuti agwirizane bwino ndi uvuni wanu.
Pamene kupanga mafakitale kukusintha kukhala njira zogwira mtima kwambiri zogwiritsira ntchito kutentha kwambiri, ma silicon carbide roller amakhalabe njira yabwino kwambiri yopangira zinthu zokhazikika komanso zotsika mtengo. Ndi magwiridwe antchito odalirika komanso kusintha kosinthika, zimathandiza kukonza magwiridwe antchito ndikukweza mpikisano wazinthu. Ngati mukufuna ma SiC roller apamwamba kapena upangiri waukadaulo, gulu lathu la akatswiri limapereka chithandizo chokwanira cha zinthu, kapangidwe ndi chithandizo chogulitsa pambuyo pogulitsa kuti chikwaniritse zosowa zanu zonse zotumizira zinthu zotentha kwambiri.
