Mukugadzirwa kwema graphite electrodes, nyaya dzekushandiswa kwesimba dzinogona kugadziriswa kuburikidza nematanho akazara, anosanganisira kugadzirisa kuyerera kwesimba, kuwedzera kushanda zvakanaka kwesimba, kusimbisa manejimendi yemidziyo, uye kushandisa matekinoroji ekuchengetedza simba. Mhinduro dzacho ndedzinotevera:
I. Kugadzirisa Maitiro Ekugadzira Calcination Yezvinhu Zvisina Kugadzirwa uye Kubika
Kugadzirisa Kugadziriswa Kwezvinhu Zvisina Kugadzirwa
Munguva yedanho re calcination, kudzora tembiricha (1,250-1,350°C) uye nguva yacho kunoderedza kusanduka kwemhepo, kunovandudza kugadzikana kwekupisa kwezvinhu zvakagadziriswa, uye kunoderedza kushandiswa kwesimba rekubika. Semuenzaniso, kutsiva mapoto echinyakare nema rotated kilns kana ma calcination emagetsi kunogona kuwedzera kushanda zvakanaka kwekupisa ne10%-15%.
Mukubika, kubika kwechipiri kana kuisirwa kakawanda (semuenzaniso, kuisirwa katatu uye kuisirwa kane) kunozadza maburi, kunoderedza kuyerera kwezvigadzirwa zvakapedzwa, uye kunowedzera huwandu hwezvinhu zvakawanda uye simba remuchina, nokudaro zvichideredza kushandiswa kwesimba rezvigadzirwa.
Kuvandudza Maitiro Ekuisa Impregnation
Muchikamu chekuisa asphalt, kugadzirisa kumanikidzwa kweasphalt injection (1.2-1.5 MPa) uye tembiricha (180-200°C) kunovandudza mwero wekuwedzera uremu mukuisa asphalt (≥14% pakuisa kekutanga uye ≥9% kwekechipiri), zvichideredza huwandu hwekubika kunodzokororwa uye kuderedza kushandiswa kwesimba zvisina kunanga.
II. Kuvandudza Tekinoroji Yekurapa Graphitization
Kugadzirisa Kupisa Kwekupisa Kwepamusoro
Munguva yekushandura girafiti, kutsiva maovheni echinyakare eAcheson neovheni dzemukati dzinopisa dzakasanganiswa (LWG) kunopfupisa nguva yekushanda nesimba (maawa 9-15 emaovheni eLWG vs. maawa 50-80 emaovheni eAcheson) uye kunoderedza kushandiswa kwemagetsi ne30%-50%.
Kunyatso dzora tembiricha ye graphitization (2,300-3,000°C) kunodzivirira kupisa zvakanyanya kwesimba ukuwo kuchive nechokwadi chekuti zvivakwa zvekabhoni zvinoshandurwa kuita makristaro e graphite akarongwa nemativi matatu, zvichiwedzera kufambisa kwemagetsi.
Kudzoreredza uye Kushandisa Kupisa Kwemarara
Munguva yekutonhodza kwemaovheni ekugadzira graphitization, kupisa kwemarara kunotorwa kuti kugadziriswe zvinhu zvisina kugadzirwa kana kugadzirwa kwemvura inopisa, zvichideredza kushandiswa kwesimba rekuwedzera. Semuenzaniso, rimwe bhizinesi rakachengetedza anopfuura 500,000 cubic metres egasi rechisikigo pagore kuburikidza nesystem yekudzoreredza kupisa kwemarara.
III. Kusimbisa Midziyo Yekugadzira uye Kutarisira Simba
Kuvandudza Kushanda Nesimba Kwemidziyo
Kusarudza ma extruder anoshanda zvakanyanya, ma screw extruder, nezvimwe zvinogadzira zvinhu kunoderedza kurasikirwa kwe mechanical friction; kushandisa tekinoroji ye variable frequency drive kudzora kumhanya kwemota kunoenderana nemitoro yekugadzira uye kuderedza kushandiswa kwesimba risingashandi.
Kugadziriswa kwemidziyo mikuru nguva dzose, yakadai semafurnace ekubikisa ne graphitization, kunoita kuti mhepo isapinda uye kunoderedza kurasikirwa nekupisa. Semuenzaniso, kuvandudza ma layers e insulation e furnace kunogona kuderedza kushandiswa kwesimba re furnace ne8%-12%.
Kutarisa uye Kugadzirisa Simba
Kushandisa Energy Management System (EMS) kunogonesa kutarisa magetsi, gasi, uye kushandiswa kwekupisa panguva chaiyo mumabasa ese, zvichivandudza zvirongwa zvekugadzira kuburikidza nekuongorora data. Semuenzaniso, kugadzirisa kurodha kwechoto chekubikira zvinoenderana nezvinodiwa neodha kunodzivirira mamiriro ezvinhu "akawandisa".
Kushandisa nzira dzekutengesa magetsi mugomo guru kunoronga maitiro anoshandisa simba rakawanda (semuenzaniso, graphitization) munguva dzisiri dzenguva refu kuti kuderedzwa kwemitengo yemagetsi.
IV. Kukurudzira Tekinoroji Dzinochengetedza Simba uye Simba Rakachena
Kushandiswa kweTekinoroji Yekugadzira Tembiricha Yakaderera
Kutsiva kugadzira simba remagetsi nekushandisa tekinoroji yekudzvanya ine simba rekupisa rakaderera kana kuti isostatic kunoderedza kushandiswa kwesimba rekupisa. Semuenzaniso, rimwe bhizinesi rakaderedza kushandiswa kwesimba patani yeelectrode ne20% kuburikidza nekugadzira simba rekupisa rakaderera.
Kutsiva Simba Rakachena
Kuisa gasi rechisikigo nemafuta ebiomass zvishoma nezvishoma panzvimbo pemarasha mukuita calcination nekubika kunoderedza kuburitswa kwecarbon uye mari yekushandisa simba. Mamwe mabhizinesi akabudirira kushandisa gasi rechisikigo neanopfuura 60%, zvichideredza kuburitswa kweCO₂ pagore nematani anopfuura 10,000.
Kugadzira Simba reKupisa Marara uye Kutenga Magetsi Asingasvibi
Kushandisa kupisa kwemarara kubva muzvitofu zve graphitization pakugadzira magetsi kunozadzisa zvinodiwa zvemagetsi zvishoma; kutenga magetsi akasvibirira (semuenzaniso, simba remhepo kana rezuva) kunoderedza kuvimba nemafuta epasi uye kunogonesa kugadzirwa kwekabhoni shoma.
V. Kuisa Kutarisira Kuchengetedza Simba Kwakazara
Kugadzirisa Chirongwa Chekugadzira
Kubatanidza maitiro akafanana (semuenzaniso, kuisirwa kwesimbi pakati nepakati uye kubika) kunoderedza kutenderera kwekumisa michina uye kunoderedza kushandiswa kwesimba panguva yekumirira. Semuenzaniso, rimwe bhizinesi rakachengetedza magetsi anopfuura mamiriyoni maviri kWh pagore kuburikidza nekugadzirisa hurongwa hwekugadzira.
Kudzidziswa Kwekuchengetedza Simba Kwevashandi
Kudzidzisa vashandi kushandisa simba nguva dzose kunovandudza ruzivo rwavo. Semuenzaniso, kugadzirisa maitiro ekutanga/kudzima michina uye kugadzirisa nzira dzekushandisa zvinhu zvinogona kuderedza kushandiswa kwesimba ne5%-8%.
Mareferensi eNyaya
- Bhizinesi Guru reGraphite Electrode: Nekuvandudza maovheni eLWG graphitization, kushandisa sisitimu yeEMS, uye kuisa marasha panzvimbo pegasi rechisikigo, bhizinesi iri rakaderedza kushandiswa kwesimba rakawanda ne35%, rakaderedza kuburitswa kwecarbon kubva muzvigadzirwa zveyuniti ne40%, uye rakachengetedza mari inodarika $7 miriyoni pagore.
- Maitiro Ekuenzanisa Maindasitiri: Mamwe mabhizinesi akabudirira kugadzira kabhoni "near-zero" kuburikidza nekudzoreredza kupisa kwemarara uye nzira dzekutenga magetsi akachena, zvichienderana nemafambiro epasi rose ekusapindirana kwekabhoni uye kuwedzera kukwikwidzana pamusika.
