Graphite muforoma kuti kuramba vachikanda
Kuenderera mberi kukanda graphite muforoma kunoreva zvigadzirwa zve graphite zvinoshandiswa mukuenderera zvichikanda kuumbwa. Simbi inoenderera ichikanda tekinoroji tekinoroji nyowani iyo inoshandura yakananga simbi yakanyungudika kuita chinhu kuburikidza nekuenderera kwekukanda muforoma. Nekuti haina kutenderera uye inova chinhu zvakananga, iyo yechipiri kupisa kwesimbi inodzivirirwa, saka simba rakawanda rinogona kuponeswa.
Kuramba kukanda graphite kunoitwa kubva carbonaceous mbishi zvinhu (peturu coke, nenamo coke, marasha nenamo ...) mushure akateedzana ekugadzira maitiro. Pakati pavo, iyo yekumanikidza yekuumba maitiro inogona kuve yakateedzana kutonhorera kuomesa kuumba kana kutonhora isostatic kudzvanya kuumbwa maitiro. Yepamberi yepamusoro-tonnage inotonhora isostatic kudzvanya maitiro inogamuchirwa kuve nechokwadi kugadzirwa kweunifomu, gobvu uye yakakwirira-simba inoenderera ichikanda graphite. Kuwedzera pamusoro pekuputira tekinoroji kurapwa kunogona kuimba hupenyu hwehupenyu hweiyo graphite crystallizer, kuvandudza mhando yeinoramba ichikanda simbi pamusoro, uye kuwedzera inoenderera ichikanda nzira yekumhanyisa.
Inofananidzwa ne graphite zvishandiso zvezvimwe zvinangwa, inoenderera ichikanda graphite ine zvinotevera hunhu: yakanaka tema, yunifomu magadzirirwo, yakakwira vhoriyamu density, yakaderera porosity uye yakakwirira simba Kuita kwayo kwekutanga kunotevera:

Muongororwo wekuvandudzwa kwekuenderera mberi kwekukanda graphite kumba nekune dzimwe nyika
1) Nyika dzinobatanidza kukosha kukuru mukusimudzira uye kushandiswa kwekuenderera mberi kukanda graphite. Izvi zvinogona kusimbiswa kubva mukuwedzera mukusiyana kwekuenderera kwekukanda graphite, kuvandudza maitiro, uye kugadzirisa mhando. Semuenzaniso, Germany neJapan vakashinga kushandisa mari yakawanda mukugadzira kusimudzira kukanda graphite, saka ivo vanogadzira mamwe marudzi eanoramba achikanda graphite, uye mhando iri nani zvakare. Mhangura profiles uye yakakanda simbi inoenderera ichikanda tekinoroji zvakare yakagadziriswa.
2) Mukutungamira kwekugadzirwa kwechigadzirwa, nyika dzekunze dzakabhadhara zvakanyanya kukudziridzwa kweyeye-yakatsetseka, yakakwira-density, isotropic graphite seinoramba ichikanda graphite. Kunyanya, iyo yeGerman Linsdorf kambani yakaunganidza chiitiko chakati munzvimbo ino uye yatora matanho mazhinji. Japan's Toyo Tansuo Kambani yave zvakare iri kubata, uye ine mukana wekupfuura. MuChina, Dongshin Electric Carbon Plant neShanghai Carbon Plant vakabudirira munzvimbo ino makore mashoma apfuura. Kuti uvandudze mashandiro ekushanda kwepamusoro kweiyo graphite crystallizer, iyo yepamusoro yekumhara tekinoroji inogamuchirwa, iyo ine simba rakakura pakuvandudzwa kwehupenyu hwebasa reiyo inoenderera ichikanda graphite. ISoviet Union yakagamuchira boron nitride yekumhanyisa tekinoroji, nepo kupfeka kweyakaenderera kukanda graphite munyika yangu kunowanzoiswa pyrolytic graphite. Kunyangwe iyo isina kuve yakanyanya kufarirwa, yakagamuchirwa nevazhinji vashandisi. Uye zvakare, iyo Shanghai Electric Carbon Plant inoshandisawo yechinyakare fomula kuwedzera 0.6 kusvika 2% yesimbi oxides, uye inoshandisa mashandiro eaya esimbi oxides kushandura kuita yakakwira melting point carbides pa2500 ℃ graphitization yakanyanya tembiricha, nokudaro ichivandudza iyo oxidation kuramba kuti kuramba kukanda graphite. Kuzadzisa chinangwa chekuvandudza hupenyu hwebasa.
3) The pamwero mukuru Specification pamusoro enderera Kudzingwa graphite rava pamusoro kukoshesa. Tichifunga nezvekuti mhando yemahombekombe anoramba achikanda graphite ine mukaha mukuru kana uchienzaniswa nenyika dzekunze, kuedza kukuru kunofanira kuitwa kuisimudzira. Izvi zvinokodzera kutarisirwa kwevagadziri, zvese maererano nehupfumi nehupfumi.
4) Munyika yangu, inoenderera ichikanda tekinoroji yemhangura maprofiles yakawedzera nekukurumidza, yakatanga kare, ine hombe chikero, uye ine yakawanda yakakura uye yakapfuma ruzivo. Iyo inoramba ichikanda tekinoroji yekuenderera ichikanda profiles ichangobva kugadzirwa, uye inoenderera yekukanda tekinoroji inodiwa Kunyange hazvo cast cast graphite ichiri kushandiswa, kumwezve kuvandudzwa uye kugadzirisa kunodiwa.
5) Kutsvagurudza kunofanirwa kuitwa kunatsiridza machining kunyatso kuenderera kwekukanda graphite muforoma uye kugadzirisa chigadzirwa chigadzirwa. Iyi zvakare imwe yematanho ekuvandudza hupenyu hweiyo graphite crystallizer. Germany neSoviet Union zvine zvirevo zvakajeka zvechigadzirwa chakashongedzwa nemazvo, uye vashandisi vepamba vanovimbawo kuti hukasha hwemadziro emukati anoramba achikanda graphite anogona kuvandudzwa, ayo anogona kunyatso kudzivirira kutsemuka pamusoro pekukanda. Uye zvakare, kuitira kuti uvandudze nyika yekubatana. Chimiro uye chimiro chenguva dzose yekukanda graphite inofanira kuvandudzwa kuitira kuti nzvimbo yekubatana pakati payo neforoma mhangura inosvika 80%.
