Ndezvipi zvinhu zvakakosha, zvakanakira uye zvakaipa zvemichina yakasiyana yekugadzira graphitized petroleum coke?

Mukugadzirwa kwe graphitized petroleum coke, michina yakasiyana inochinja marongerwo emaatomu ekabhoni kuburikidza nemisimboti yayo yakasiyana yemaitiro, uye zvakanakira nekuipira kwayo zvinoratidzwa zvakanyanya mukushandiswa kwesimba, kushanda zvakanaka, mhando yechigadzirwa, uye mari yekugadzirisa michina. Pazasi pane ongororo yemidziyo mikuru, pamwe chete nemisimboti yayo, zvakanakira, nekuipira:

I. Girafu yeGraphitization (Midziyo Yepakati)

Nheyo:
Chitofu che graphitization chinoshandisa kupisa kwakanyanya (kazhinji kusvika 2400-3000°C), chichishandisa simba rekupisa kuti chiite kuti maatomu ekabhoni achinje kubva pachimiro chakakanganiswa kuenda kuchimiro che graphite crystal, nokudaro chichipedzisa maitiro e graphitization. Chinangwa chayo chiri mukupa nharaunda inogara kwenguva refu uye yakafanana yekupisa kwepamusoro kuti zvigone kurongekazve kwemaatomu ekabhoni mukati me petroleum coke.

Zvakanakira:

• Hunhu Hwepamusoro hweChigadzirwa: Inogona kugadzira petroleum coke ine graphitized ine kabhoni yakawanda, sarufa shoma, uye nitrogen shoma, ichizadzisa zvinodiwa zvema carburizer muindasitiri dzesimbi dzemhando yepamusoro, simbi dzakakosha, uye simbi.
• Maitiro Ekukura: Sezvishandiso zvechinyakare, nzira yayo yetekinoroji yakagadzikana uye yakakodzera kugadzirwa kukuru.

Zvakashata:

• Kushandiswa Kwesimba Rakawanda: Kugadzira graphite pakupisa kwakanyanya kunoda simba guru remagetsi, zvichiita kuti ive inenge 50% yemari yose yekugadzira graphite yakagadzirwa.
• Kureba Kwekugadzirwa: Maovheni ekugadzira graphitization anoda mazuva gumi kusvika makumi maviri ekutonhodza uye kuburitsa zvinhu, zvichiita kuti kuenderera mberi kwekugadzirwa kuwedzere.
• Mari Yakawanda Yokugadzirisa Midziyo: Nzvimbo inodziya zvakanyanya inokurumidza kukwegura kwezvinhu zvechoto, zvichiita kuti zvidikanwe nguva nenguva.

II. Furnace Inoramba Ichishandiswa paGraphitization (Midziyo Yakavandudzwa)

Nheyo:
Furnace inoenderera mberi yegraphitization inoshandisa dhizaini yenzvimbo yekupisa inoshanduka, zvichiita kuti petroleum coke ikwanise kuoma, kucheneswa, kucheneswa, uye kutonhora sezvinoita ichifamba muchoto, zvichiita kuti irambe ichigadzirwa. Chinhu chikuru chiri mukupfupisa nguva yekugadzirisa pachikamu chimwe nechimwe kuburikidza nekuyerera kwezvinhu.

Zvakanakira:

• Kushanda Nesimba Kwazvo Mukugadzira: Pasina kukanganiswa kwemagetsi, zvinhu zvinogara zvichifamba muchoto, zvichideredza nguva yekugadzirisa pabatch imwe neimwe kusvika kumaawa akati wandei kusvika kumazuva.
• Kushandiswa Kwesimba Rakaderera: Nekushandisa kupisa zvakanaka uye kuderedza kudzokororwa kwekupisa kusingawanzoitiki, simba rinoshandiswa pachigadzirwa chimwe nechimwe rinoderedzwa.
• Hunhu Hwechigadzirwa Hwakagadzikana: Kudzora tembiricha inochinja-chinja kunoderedza kupisa kwakanyanya kana kupisa kusingakwane, zvichiwedzera kugadzikana kwechigadzirwa.

Zvakashata:

• Kuomarara Kwemidziyo: Kudzora kwakanyatsojeka kwekufamba kwezvinhu, kupararira kwenzvimbo yekupisa, nezvimwe zvinodiwa, zvichiita kuti pave nemuganho wepamusoro wehunyanzvi.
• Mari Yekutanga Yakakwira: Mari yekuvaka yemutsetse wekugadzira unoenderera mberi yakakwira kupfuura yemidziyo yechinyakare.

III. Muchina wekugadzira weUltrafine (Midziyo Yekubatsira)

Nheyo:
Muchina wekukuya we ultrafine grinder unoshandisa kukurumidza kugongana, kuchekerera, uye kuburitsa zvinhu kuti upwanye graphitized petroleum coke kuita zvidimbu zve micron (semuenzaniso, 200 mesh), zvichizadzisa zvinodiwa zvezvidimbu zvemashandisirwo chaiwo akadai sezvinowedzera rabha.

Zvakanakira:

• Kudzora Saizi yeZvidimbu Zvakanyatsonaka: Inogona kugadzira hupfu hwakatsetseka hwakasiyana-siyana hunotangira pa 0.001-0.1mm, huchienderana nezvinodiwa pamusika.
• Dhizaini Yekupfeka Zvishoma: Kushandisa zvinhu zvakasimba zvesimbi pakukuya nyundo nemhete dzegiya kunopa hupenyu hwemuchina.
• Kuzvigadzira Kwepamusoro: Masisitimu akabatanidzwa ekupatsanura uye ekuunganidza anoderedza kupindira nemaoko, zvichiwedzera kugadzikana kwekugadzira.

Zvakashata:

• Kushandiswa Kwesimba Rakawanda Nekugadziriswa Kwehukuru hweZvidimbu: Kukuya kusvika pamazinga e micron kunoda simba rakawanda, zvichiwedzera kushandiswa kwesimba rechigadzirwa.
• Mutengo Mukuru weMidziyo: Zvinhu zveSuperhard alloy uye masisitimu ekupatsanura nemazvo zvinobatsira pakudyara mari yekutanga kwakakwira.

IV. Choto cheCalcination (Midziyo Yekurapa Pamberi)

Nheyo:
Chitofu che calcination chinobata coke yepetroleum isina kubikwa pa1300°C kubvisa zvinhu zvinoshanduka uye kuwedzera kabhoni, zvichipa zvinhu zvemhando yepamusoro zve graphitization inotevera. Chinhu chikuru chiri mukudzora tembiricha ye calcination nenguva yekudzivirira kupisa kwakanyanya.

Zvakanakira:

• Hunhu Hwakanaka hwezvinhu zvakakangwa: Kugadziriswa kwecalcium kunoderedza zvinhu zvinoshanduka uye kunowedzera simba remuchina, zvichiita kuti petroleum coke ive yakakodzera kushandiswa pakugadzira graphitization.
• Kuenderana Kwakasimba Kwemaitiro: Inogona kugadzirisa coke yepetroleum isina kugadzirwa kubva kunzvimbo dzakasiyana-siyana, ichigamuchira kusiyana kwezvinhu zvakabikwa.

Zvakashata:

• Kushandiswa Kwesimba Rakawanda: Kupisa nguva dzose kuti pave nekupiswa kwakanyanya kunowedzera mitengo yesimba.
• Kumanikidzwa Kwakakosha Kwezvakatipoteredza: Kupisa kwezvinhu zvinoshanduka kunogona kuburitsa tsvina, zvichiita kuti pave nemaitiro ekurapa gasi remusana.

V. Kuenzanisa kweMidziyo uye Mazano ekusarudza

Zvinokurudzirwa pakusarudza:

• Isa chitofu che graphitization pakutanga kana mhando yepamusoro yechigadzirwa uye kugadzikana kwacho kuri kukuru, uye kukanganiswa kwemutengo kwakaderera.
• Sarudza chitofu chekugadzira graphitization chinogara chichishandiswa kana kuwedzera kushanda zvakanaka kwekugadzira uye kuderedza kushandiswa kwesimba zviri zvinhu zvinonyanya kukosheswa.
• Muchina wekukuya we ultrafine unokosha zvikuru kana uchitarisa misika yemhando yepamusoro yeupfu hwakakura-diki.
• Chitofu che calcination, sechishandiso chekugadzirisa, chinofanira kugadziriswa zviri nyore zvichienderana nemhando yezvinhu zvakabikwa.
