Kugwiritsa ntchito kwakukulu kwa zinthu za graphite

Zogulitsa za graphite zimatha kutulutsa kuwala kwa infrared pambuyo pa kutentha.

Magnesium-carbon njerwa Magnesium-carbon refractory ndi pakati pa nthawi, opangidwa ndi United States, Japanese steelmaking makampani anayamba kugwiritsa ntchito magnesium-carbon njerwa madzi ozizira arc ng'anjo smelting. Njerwa za kaboni za Magnesia zakhala zikugwiritsidwa ntchito kwambiri popanga zitsulo padziko lonse lapansi ndipo zafala kwambiri popanga graphite. Kumayambiriro kwa zaka khumi, njerwa za magnesium-carbon zinayamba kugwiritsidwa ntchito poyatsira chosinthira chowomberedwa ndi mpweya.

Aluminiyamu mpweya njerwa zotayidwa mpweya refractory zipangizo zimagwiritsa ntchito mosalekeza kuponyera, lathyathyathya zitsulo billet kudziona udindo mapaipi linga chivundikiro, m'madzi nozzle ndi mafuta bwino kuphulika yamphamvu. Chitsulo chopangidwa ndi kuponyedwa kosalekeza ku Japan chimaposa ndalama zonse zomwe zimapangidwa.

Zopangira zopangira ndi zofananira zopangidwa ndi graphite akamaumba ndi crucible refractory ndi zinthu zina zofananira, monga crucible, khosi lopindika botolo, pulagi ndi nozzle, ndi zina zambiri, zimakhala ndi kukana kwamoto, kutsika kwamafuta ochepa, kusungunula zitsulo, kulowetsa chitsulo ndikukokoloka. khola, kukhazikika kwabwino kwa kutentha kwamatenthedwe pa kutentha kwambiri komanso kuwongolera kwambiri, Chifukwa chake, graphite crucible ndi zinthu zake zokhudzana ndizomwe zimagwiritsidwa ntchito kwambiri pakusungunuka kwachitsulo mwachindunji. The chikhalidwe graphite dongo crucible amapangidwa ndi mpweya zili zazikulu kuposa sikelo graphite, kawirikawiri sikelo graphite ayenera kukhala wamkulu kuposa mauna (- chophimba), ndi zofunika kusintha luso lachilendo crucible kupanga ndi kuti mtundu wa graphite ntchito, sikelo. kukula ndi khalidwe ndi kusinthasintha kwambiri kutsatiridwa ndi ntchito silicon carbide graphite crucible m'malo chikhalidwe dongo graphite crucible. Izi ndichifukwa chakuyambitsa ukadaulo wokakamiza nthawi zonse mumakampani opanga zitsulo. Kugwiritsa ntchito nthawi zonse kukakamiza umisiri kungapangitsenso kuti ma graphite ang'onoang'ono agwiritsidwe ntchito, mu dongo la graphite crucible, ndi silicon carbide graphite crucible, zomwe zili ndi zigawo zazikuluzikulu zimangowerengera, ndipo kaboni wa graphite umachepetsedwa.

kupanga zitsulo

Graphite ndi zinthu zina zonyansa zitha kugwiritsidwa ntchito ngati ma carburizer pamakampani opanga zitsulo. Carburizing amagwiritsa ntchito zinthu zosiyanasiyana za carbonaceous, kuphatikizapo graphite yokumba, petroleum coke, coke metallurgical ndi graphite yachilengedwe. Graphite akadali imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri padziko lapansi ngati graphite.

Zinthu zoyendetsera

Graphite amagwiritsidwa ntchito kwambiri m'makampani amagetsi monga maelekitirodi, maburashi, ndodo za kaboni, machubu a kaboni, machubu a mercury, ma graphite gaskets, mbali za foni, zokutira zapa TV ndi zina zotero. Pakati pawo, graphite elekitirodi ndi ambiri ankagwiritsa ntchito, mu smelting zosiyanasiyana aloyi zitsulo, aloyi chitsulo, ntchito graphite elekitirodi, ndiye amphamvu panopa kudzera elekitirodi mu ng'anjo kusungunuka zone, kupanga arc, kuti mphamvu yamagetsi mu kutentha mphamvu, kutentha kumakwera mpaka pafupifupi, kuti akwaniritse cholinga chosungunuka kapena kuchitapo kanthu. Kuphatikiza apo, electrolyzing magnesium, aluminium ndi sodium, anode ya cell electrolytic imagwiritsanso ntchito graphite electrode. Graphite elekitirodi amagwiritsidwanso ntchito ngati zinthu conductive mutu ng'anjo kupanga ng'anjo abrasive kukana. Ma graphite omwe amagwiritsidwa ntchito pamakampani amagetsi ali ndi zofunika kwambiri pakukula kwa tinthu ndi kalasi. Monga mabatire amchere ndi zinthu zina zapadera zamagetsi zamagetsi, kukula kwa tinthu tating'ono ta graphite kumafunika kuwongolera mkati mwa polojekitiyi, kalasiyo ili pamwamba, ndipo zonyansa zovulaza (makamaka chitsulo chachitsulo) ziyenera kukhala pansipa. Ma graphite omwe amagwiritsidwa ntchito mu chubu lachithunzi cha TV ali ndi zofunikira za kukula kwa tinthu. Graphite nthawi zambiri amagwiritsidwa ntchito ngati mafuta opangira makina. Mafuta opaka mafuta nthawi zambiri sangagwiritsidwe ntchito mothamanga kwambiri, kutentha kwambiri, kupanikizika kwambiri, ndi zipangizo zosagwirizana ndi graphite zimatha kugwira ntchito popanda mafuta odzola - kutentha komanso kuthamanga kwambiri. Zida zambiri zotumizira zowononga zowononga, zomwe zimagwiritsidwa ntchito kwambiri ndi ma graphite opangidwa ndi mphete za pistoni, zisindikizo ndi zonyamula, zikamathamanga, sizifunikira kuwonjezera mafuta opaka mafuta, mkaka wa graphite umakhalanso mafuta abwino opangira zitsulo zambiri (kujambula waya, kujambula chubu).

Zinthu zolimbana ndi dzimbiri

Graphite ali ndi kukhazikika kwa mankhwala. Mwapadera kukonzedwa graphite ali makhalidwe a kukana dzimbiri, madutsidwe wabwino matenthedwe ndi permeability otsika, ndipo chimagwiritsidwa ntchito kupanga exchangers kutentha, akasinja anachita, condensers, nsanja kuyaka, nsanja mayamwidwe, coolers, heaters, Zosefera, mapampu ndi zipangizo zina. Zidazi zimagwiritsidwa ntchito mu petrochemical, hydrometallurgy, asidi ndi alkali kupanga, fiber synthetic, mapepala ndi magawo ena a mafakitale, amatha kupulumutsa zitsulo zambiri. 0 Pakuti kuponyera, mchenga, kukanikiza ndi mkulu-kutentha metallurgical zipangizo chifukwa yaing'ono kukula coefficient ya graphite, ndi luso kusintha kuzizira ndi kutentha, angagwiritsidwe ntchito ngati galasi nkhungu, pambuyo ntchito graphite, ndi wakuda zitsulo castings analandira. kukula kolondola, pamtunda wosalala, zokolola zambiri, zingagwiritsidwe ntchito popanda kukonzedwa kapena kukonzedwa pang'ono, motero kupulumutsa zitsulo zambiri. Kupanga kwa carbide ndi njira zina zazitsulo za ufa, zomwe nthawi zambiri zimapangidwa ndi zida za graphite zolimbikitsira kukana kwa mabwato. Monocrystalline silicon crystal kukula crucible, chotengera choyenga chigawo, bulaketi, fixture, chotenthetsera chotenthetsera, etc., amakonzedwa ndi chiyero choyera cha graphite. Komanso, graphite Angagwiritsidwenso ntchito ngati zingalowe zitsulo graphite kutchinjiriza mbale ndi maziko, kutentha kukana ng'anjo ng'anjo chubu, ndodo, mbale, gululi ndi zigawo zina.

Mphamvu za atomiki

Graphite ali wabwino neutroni deceleration ntchito, woyamba monga woyang'anira ntchito mu riyakitala atomiki, uranium-graphite riyakitala ndi zambiri ntchito atomiki riyakitala. Monga mphamvu ya atomiki mphamvu riyakitala deceleration zakuthupi ayenera kukhala mkulu kusungunuka mfundo, bata, kukana dzimbiri, graphite akhoza mokwanira kukwaniritsa zofunika pamwamba. Chiyero cha graphite chomwe chimagwiritsidwa ntchito ngati atomiki riyakitala ndichokwera kwambiri, ndipo zonyansa siziyenera kupitilira makumi (gawo limodzi pa miliyoni), makamaka zomwe zili mu boron ziyenera kukhala zosakwana.

Anti-fouling ndi anti-dzimbiri zinthu

Graphite ingalepheretse kuwotcha makulitsidwe, mayeso oyenera agawo akuwonetsa kuti kuwonjezera kuchuluka kwa ufa wa graphite m'madzi (pafupifupi tani imodzi yamadzi) kungalepheretse kukula pamtunda. Komanso, graphite ntchito zitsulo chimneys, madenga, milatho, mapaipi akhoza kukhala odana ndi dzimbiri ndi odana ndi dzimbiri.

Ntchito zina

Ndi chitukuko chosalekeza cha sayansi ndi luso lamakono, anthu apanga ntchito zambiri zatsopano za graphite. Zosintha za graphite. Flexible graphite, yomwe imadziwikanso kuti graphite yowonjezera, ndi chinthu chatsopano cha graphite chomwe chinapangidwa m'ma 1990. United States bwinobwino kafukufuku wosinthika graphite kusindikiza zipangizo kuthetsa kutayikira vuto mavavu atomiki mphamvu, ndiyeno Germany, Japan ndi France anayambanso kupanga ndi kupanga. Kuphatikiza pa mawonekedwe a graphite achilengedwe, mankhwalawa ali ndi kusinthasintha kwapadera komanso kusinthasintha. Choncho, ndi chinthu choyenera chosindikizira. Amagwiritsidwa ntchito kwambiri mu petrochemical, mphamvu ya atomiki ndi mafakitale ena. Kufunika kwa msika wapadziko lonse kukuwonjezeka chaka ndi chaka.

Zinthu zoyera kwambiri zimagwiritsidwa ntchito pakusungunula zitsulo zoyera, zamagetsi zamagetsi, mafakitale anyukiliya komanso kupanga nkhungu; mankhwala wamba ntchito zotayidwa electrolysis thanki, ufa zitsulo sintering ng'anjo, ferroalloy ng'anjo ndi zina mchere ng'anjo zomangamanga zipangizo.

Kampani yathu imatha kupatsa makasitomala mitundu yosiyanasiyana yamakina opanga ma graphite, ndinu olandilidwa kuti mupereke zojambula mwamakonda zokhazokha. Posachedwapa, kampani yathu wapereka makonda graphite bushing mankhwala makasitomala akale, malinga ndi zojambula ndi zofunika operekedwa ndi makasitomala akale, khalidwe ndi kuchuluka, anamaliza pa nthawi ndi kuperekedwa monga analonjezedwa, kuyembekezera kupambana chikhulupiriro cha makasitomala ambiri ndi ukatswiri wathu ndi umphumphu. .
