Chii chinoshandiswa nesimba rekugadzira graphitization process ye graphitized petroleum coke?

Maitiro ekugadzira graphitization e graphitized petroleum coke imhando yekugadzirwa kunoshandisa simba rakawanda, ine hunhu hwayo hwekushandisa simba uye zvinhu zvakakosha zvinopesvedzera zvinotsanangurwa seizvi:

I. Ruzivo rweKushandiswa kweSimba Guru

1. Musiyano Pakati Pekushandisa Simba Redzidziso Nerechokwadi Kana tembiricha yegirafitisiti yasvika 3,000°C, simba rinoshandiswa nedzidziso patani imwe chete yezvigadzirwa zvakabikwa i1,360 kWh. Zvisinei, mukugadzira chaiko, mabhizinesi emuno anowanzo shandisa 4,000–5,500 kWh patani, inova ka3–4 kukosha kwedzidziso. Semuenzaniso, chirimwa chikuru chekabhoni chinoburitsa matani 100,000 emagetsi egirafititi pagore chinoshandisa 3,000–5,000 kWh patani panguva yegirafitisiti ...pisisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitisitisitisitisitisitipisisitisitipisisitisitipisisitisitisitisitisitisitisitisitisitisitipisi

II. Kuongororwa kweZvikonzero zveKushandiswa Kwesimba Rakawanda

1. Zvinodiwa Pakuita Zvinhu Zvikuru Kugadzira girafiti kunoda kurapwa nekupisa kwakanyanya (2,800–3,000°C) kushandura maatomu ekabhoni kubva pachimiro chakakanganiswa kuita chimiro chekristaro chegirafiti chakarongeka. Maitiro aya anoda simba rinogara richiiswa kuti rikunde kuramba kupindirana kwemaatomu, zvichikonzera kushandiswa kwesimba kwakawanda.

2. Kushanda Kwakaderera Kwemaitiro Echinyakare

• Acheson Furnace: Nzira huru, asi ine 30% chete yekushanda zvakanaka kwekupisa, zvichireva kuti 30% chete yesimba remagetsi rinoshandiswa kugadzira graphiting zvigadzirwa, nepo yasara ichiraswa kuburikidza nekuparadza kupisa kwechoto uye kushandiswa kwezvinhu zvinodzivirira.
• Kushanda Kwemagetsi Marefu: Nguva yekushanda kwemagetsi muchoto chimwe chete inotangira pamaawa makumi mana kusvika zana, uye nguva yekugadzira inogara kwemazuva makumi maviri kusvika makumi matatu, zvichiwedzera kuwedzera kwekushandiswa kwesimba. 3. Zvipingamupinyi zveMidziyo neMashandiro
• Kuwanda kwesimba remagetsi emufurnace kunogumira pakukwanisa kwemagetsi. Kuwedzera kwesimba remagetsi kunogona kupfupisa nguva yekushanda kwemagetsi asi kunoda kuvandudzwa kwemidziyo, zvichiwedzera mari yekudyara.
• Kukwira kwekupisa kunodziviswa kudzivirira kupwanyika kwechinhu kubva mukushushikana kwekupisa, zvichideredza nzvimbo yekuderedza kushandiswa kwesimba.

III. Kufambira Mberi uye Mhedzisiro yeTekinoroji Dzinochengetedza Simba

1. Kushandiswa kweMhando Itsva dzeVira

• Internal Series Graphitization Furnace:Principle: Inodziya maelectrode zvakananga pasina zvinhu zvinodzivirira, zvichideredza kurasikirwa nekupisa.Mhedzisiro: Inoderedza kushandiswa kwesimba ne20%–35% uye inopfupisa nguva yekupisa kusvika kumaawa manomwe kusvika gumi nematanhatu.
• Furnace yerudzi rweBhokisi: Musimboti: Inokamura core yefurnace kuita makamuri akawanda, nezvinhu zveanode zvakaiswa mumabhokisi ane graphite anofambisa mhepo izvo zvinozvipisa pazvinofambiswa. Mugumisiro: Inowedzera kugona kushanda kwefurnace imwe chete, inowedzera kushandiswa kwesimba rose ne ~10% chete, inoderedza kushandiswa kwesimba reyuniti ne40%–50%, uye inobvisa mari yezvinhu zvinodzivirira.
• Furnace Inoramba Ichienderera: Musimboti: Inogonesa kugadzirwa kwakabatana kunoramba kuchienderera mberi (kurodha, kupa simba, kutonhora, kuburitsa zvinhu), kudzivirira kurasikirwa nekupisa kubva pakushanda kwechoto nguva nenguva. Mhedzisiro: Inoderedza kushandiswa kwesimba ne ~60%, inopfupisa zvakanyanya kutenderera kwekugadzira, uye inovandudza otomatiki. 2. Matanho Ekugadzirisa Maitiro
• Magadzirirwo ekudzivirira kupisa muchoto akagadziridzwa kuderedza kurasikirwa nekupisa uye kuwedzera kushanda zvakanaka kwekupisa.
• Kugadzirwa kwemagadzirirwo enzvimbo dzinopisa dzinoshanda zvakanaka kuti pave nekupararira kwekupisa kwakafanana uye kushandiswa kwesimba kushoma.
• Masisitimu ekudzora tembiricha akangwara ane kutarisa kwenzvimbo dzakawanda uye maalgorithms akangwara ekugadzirisa macurve ekupisa nemazvo, kudzivirira kutambisa simba.

IV. Mafambiro neMatambudziko muIndasitiri

1. Kutamiswa Kwesimba Kugona kweGraphitization kuri kunyanya kuchamhembe kwakadziva kumadokero kweChina, zvichishandisa mitengo yakaderera yemagetsi emuno kuderedza mitengo. Semuenzaniso, Inner Mongolia inokwana 47% yesimba renyika reGraphitization, ichiva nzvimbo huru yekugadzira. 2. Kuvandudzwa Kwetekinoroji Kunotungamirirwa Nemutemo Pasi pemitemo yekushandisa simba "mbiri", kugona kweGraphitization ine simba rakawanda kunotarisana nezvirambidzo, zvichimanikidza mabhizinesi kuti atore maitiro ekuchengetedza simba. Makambani ane hunyanzvi hwekugadzira hwakabatana (semuenzaniso, kuzvipa graphitization) anowana mabhenefiti emakwikwi, zvichikurumidzisa kubatana kwemusika kune vatambi vanotungamira. 3. Njodzi Yekutsiva Tekinoroji Nepo maovheni anoenderera mberi nemamwe matekinoroji matsva achichengetedza simba zvakanyanya, mitengo yavo yepamusoro yemidziyo uye zvipingamupinyi zvetekinoroji zvinodzivisa kukurumidza kutsiviwa kwemaovheni echinyakare eAcheson. Makambani anofanira kuyera mari yekuvandudza tekinoroji nekubatsira kwenguva refu.
