Silicon Carbide Beam Redefining Kiln Support Systems

Kufotokozera Kwachidule:

Miyala ya silicon carbide (SiC) ndi zinthu zapamwamba zopangidwa ndi ceramic zopangidwa kuchokera ku zipangizo za silicon carbide zoyera kwambiri kudzera mu reaction bonding, sintering yopanda kupanikizika, kapena recrystallization processes. Yodziwika chifukwa cha mphamvu zawo zapamwamba kutentha, kukana okosijeni, komanso kukana kutentha, SiC beams yakhala zinthu zofunika kwambiri zonyamula katundu m'mafakitale amakono komanso zida zoyeretsera kutentha.

Chidule cha Zamalonda

Mu uvuni wachikhalidwe, matabwa nthawi zambiri amapangidwa ndi njerwa zosalimba kapena zinthu zopangidwa ndi alumina. Ngakhale kuti ndi zotsika mtengo, matabwa oterewa amawonongeka mosavuta kutentha kwambiri, amawonongeka mwachangu, ndipo amakhala ndi moyo waufupi wautumiki. Mosiyana ndi zimenezi, matabwa a SiC amatha kugwira ntchito mosalekeza pa 1380°C–1650°C pamene akusunga mawonekedwe abwino a makina. Moyo wawo wautumiki ndi wautali nthawi 5–10 kuposa wa matabwa achikhalidwe, zomwe zimachepetsa kwambiri ndalama zokonzera, nthawi yogwira ntchito, komanso ndalama zonse zogwirira ntchito.

Ubwino Waukulu wa Magwiridwe Antchito

Kukana Kutentha Kwambiri

Yokhoza kugwira ntchito kwa nthawi yayitali kuposa 1380°C, yokhala ndi zipangizo zapamwamba za SiC zosungunuka zomwe zimapirira kutentha mpaka 1650°C.
Imasunga kapangidwe kake bwino pakatentha kwambiri, makamaka yoyenera kugwiritsidwa ntchito m'mauvuni akuluakulu okhala ndi ma tunnel ndi ma roller kilns.

Katundu Wapamwamba wa Makina

Mphamvu yokhazikika ya kupindika: 250–350 MPa, yokulirapo kangapo kuposa mipiringidzo yachizolowezi yopingasa.
Kulimba kwambiri (Mohs ~ 9.0) kumatsimikizira kukana kwa nthawi yayitali kuwonongeka ndi kusinthika.
Kukana kwabwino kwambiri kwa kukwawa kumaletsa kugwa kapena kugwedezeka panthawi yogwira ntchito kwa nthawi yayitali.

Kukana Kwambiri kwa Kutentha kwa Matenthedwe

Imapirira kutentha ndi kuzizira mofulumira popanda kusweka.
Imapirira kusinthasintha kwa kutentha kopitilira 1000°C, yabwino kwambiri kwa ma uvuni omwe amayikidwa nthawi zambiri.

Kukana Kutupa ndi Kutupa

Imalimbana ndi mlengalenga wa acidic ndi alkaline, komanso mlengalenga wopangitsa kuti zinthu zisinthe.
Pa kutentha kokwera, pamwamba pa SiC pamapanga gawo lolimba la SiO₂ loteteza, lomwe limateteza bwino ku okosijeni wowonjezera.

Yopepuka komanso Yosunga Mphamvu

Kuchuluka kwake kumakhala pakati pa 2.6–3.1 g/cm³, kopepuka kuposa chitsulo, zomwe zimachepetsa katundu wa uvuni.
Kuyendetsa bwino kutentha kumathandiza kuti kutentha kusamutsidwe bwino, kuchepetsa kugwiritsa ntchito mafuta, komanso kuonetsetsa kuti zinthu zikugwiritsidwa ntchito mofanana.

Moyo Wowonjezera wa Utumiki

Nthawi yogwiritsira ntchito nthawi zonse: zaka 3-5 kapena kuposerapo, poyerekeza ndi miyezi 6-12 yokha ya matanthwe achikhalidwe opindika.
Kuchepa kwa nthawi yosinthira zinthu kumachepetsa nthawi yopuma komanso kukonza, zomwe zimapangitsa kuti ntchito ikule bwino.

Mafomu ndi Mafotokozedwe a Zamalonda

Matabwa a SiC amapangidwa m'njira zosiyanasiyana kuti agwirizane ndi mapangidwe osiyanasiyana a uvuni ndi zofunikira pakugwiritsa ntchito:

Matabwa Ozungulira a Ndodo: Kukula kwa m'mimba mwake Φ30–Φ80 mm; yoyenera ma uvuni opepuka komanso onyamula katundu wochepa.
Matabwa Olimba A Sikweya: Magawo opingasa pakati pa 30×30 mm – 100×100 mm; abwino kwambiri ponyamula katundu wolemera komanso nthawi yayitali.
Malo Opanda Chipinda / Mipiringidzo ya I: Yopepuka komanso yolimba kwambiri; imagwiritsidwa ntchito kwambiri m'mauvuni akuluakulu a ngalande ndi mauvuni ozungulira.
Matabwa Opangidwa Mwamakonda: Yopangidwa molingana ndi zojambula za makasitomala ndi kapangidwe ka uvuni kuti igwirizane bwino ndi zinthu zina.

Kutalika Kwanthawizonse: 500 mm – 4500 mm (kukula kwake kulipo ngati mutapempha).

Minda Yofunsira

1. Makampani Opanga Zoumba

Matabwa a silicon carbide (SiC) amagwiritsidwa ntchito kwambiri mu uvuni zopangira ceramic, makamaka popangirakunyamula katundu, kuthandizira, ndi kusamutsa kutentha.

Zoumbaumba zomwe zimagwiritsidwa ntchito tsiku ndi tsiku: mbale, mbale, makapu, ndi zina zophikira zapakhomo m'mauvuni a ngalande ndi mauvuni ozungulira.
Zoumba zaukhondo: zimbudzi, mabeseni ochapira, ndi zinthu zina zazikulu zomwe zimafuna mphamvu yonyamula katundu wamphamvu panthawi yowotcha kwambiri kwa nthawi yayitali.
Zoumba zadothi: matailosi apansi, matailosi a pakhoma, ndi matabwa akuluakulu a ceramic, komwe matabwa a SiC amaonetsetsa kuti zinthu zikuyenda bwino komanso kutentha kofanana.
Zojambulajambula zaukadaulo/zomangamanga: monga alumina kapena silicon nitride ceramics, zomwe zimafuna kutentha kwambiri komanso kuzungulira kwa nthawi yayitali, zomwe zimapangitsa kuti moyo wautali wa SiC beams ukhale wofunikira.

2. Makampani Ogulitsa Magalasi

Ma uvuni ophikira magalasi: zipangizo zothandizira mabotolo, magalasi, ndi magalasi athyathyathya panthawi yopopera.
Kupukuta galasi: popanga magalasi apadera (galasi lowala, galasi lowonetsera, ndi zina zotero), SiC dayamondi imatsimikizira kukhazikika kwa miyeso ndi kusamutsa kutentha kofanana.

Ubwino: kusasintha, kutentha mwachangu, komanso kuchepa kwa zolakwika zomwe zimapangidwa chifukwa cha kupsinjika kosagwirizana.

3. Makampani Opanga Zitsulo ndi Ufa

Kuchotsa zitsulo za ufa: zigawo za kapangidwe kake zochokera ku chitsulo, chitsulo chosapanga dzimbiri, ndi ufa wina wachitsulo.
Zipangizo zamaginito: maginito a ferrite, oyaka pa 1200–1400°C, omwe amafunika kuwala kolimba komwe kumateteza kutentha kwambiri komanso nthawi yayitali yogwira ntchito.
Zinthu zosowa zapadziko lapansi: kuwotcha ma oxides a rare earth kapena carbonates, nthawi zambiri mumlengalenga wovuta wa uvuni.

SiC beams excelpolimbana ndi kukhuthala ndi dzimbiri, zomwe zimapangitsa kuti zikhale zoyenera malo ovuta okhala ndi zitsulo.

4. Zipangizo Zamankhwala ndi Zatsopano Zamphamvu

Kalisiyumu ya Catalyst: ma zeolite, ma molecular seeves, ndi ma catalyst a petroleum omwe amawotchedwa mu uvuni wa mankhwala otentha kwambiri.
Zipangizo zatsopano zamagetsi:
- Zipangizo za cathode za batri ya lithiamu (NCM, LFP).
- Mphamvu ya haidrojeni ndi zinthu zamafuta zimayatsidwa.

Ubwino: kuchepetsa kugwiritsa ntchito mphamvu, nthawi yayitali yogwirira ntchito, komanso kusinthasintha kwa zinthu.

Mafunso Ofunsidwa Kawirikawiri - Miyala ya Silicon Carbide

1. Kodi kutentha kwakukulu kogwira ntchito kwa matabwa a silicon carbide ndi kotani?

Miyala ya silicon carbide imatha kugwira ntchito modalirika pa1380°C–1650°Cpopanda kusintha kwakukulu kapena kutayika kwa mphamvu. Kuchuluka kwenikweni kumadalira njira yopangira (yolumikizidwa ndi reaction, sintered sintered, kapena recrystallized SiC).

2. Kodi ubwino wa SiC beams ndi wotani poyerekeza ndi refractory beams zachikhalidwe?

Mphamvu yapamwamba(mphamvu yopindika 250–350 MPa)
Moyo wautali wautumiki(nthawi zambiri zimakhala zaka 3-5, nthawi 5-10 kuposa mithunzi yachikhalidwe)
Kulemera kopepuka, kuchepetsa katundu wa uvuni
Kukana bwino kutentha kwa kutentha, yoyenera kugwira ntchito zoyimitsa uvuni pafupipafupi
Kugwiritsa ntchito mphamvu zochepa, kukonza bwino kutentha

3. Kodi pali mawonekedwe ndi makulidwe otani?

Matabwa ozungulira: Φ30–Φ80 mm
Matabwa olimba a sikweya: 30×30 mm – 100×100 mm
Malo ozungulira / mipiringidzo ya I: mapangidwe opepuka a ma spans akuluakulu
Matabwa opangidwa mwamakonda: yopangidwa mwaluso malinga ndi zojambula za uvuni ndi zofunikira

Kutalika kwa mzere: 500–4500 mm (kukula kovomerezeka kulipo).

Zambiri zaife

XKH imagwira ntchito kwambiri pakupanga, kupanga, ndi kugulitsa magalasi apadera a kuwala ndi zinthu zatsopano zamakristalo. Zogulitsa zathu zimapereka zinthu zamagetsi, zamagetsi, ndi zankhondo. Timapereka zinthu za Sapphire optical, zophimba ma lens a foni yam'manja, Ceramics, LT, Silicon Carbide SIC, Quartz, ndi ma crystal wafers a semiconductor. Ndi ukatswiri waluso komanso zida zamakono, timachita bwino kwambiri pokonza zinthu zosakhazikika, cholinga chathu ndi kukhala kampani yotsogola kwambiri yaukadaulo wamagetsi.
