Nekuda kwekuita kwakanaka kwema graphite electrode kunosanganisira kukwirisa, kupikisa zvakanyanya kuvhunduka kwekupisa uye kuparara kwemakemikari uye kuderera kwakaderera, magirafu emagetsi ari kuita basa rakakosha muEAF kugadzira simbi panguva yeindasitiri yesimbi yemazuva ano uye simbi yekuda kuvandudza kushanda zvakanaka, kuderedza mitengo, uye kusimudzira. kugarika.
Chii chinonzi Graphite Electrode?
GRAPHITE ELECTRODES ndiyo yakanakisa conductive zvinhu zvemagetsi arc furnace nechoto chekunyungudutsa, Dzakagadzirwa nemhando yepamusoro tsono cokes yakasanganiswa, yakaumbwa, yakabikwa uye graphitization process kuti igadzire chigadzirwa chakapedzwa. GRAPHITE ELECTRODES inonyatsokodzera kushandiswa munzvimbo dzinopisa uye inogona kumira kupisa kwakanyanyisa pasina kuputsa.Iri ikozvino ndiyo yega chigadzirwa chiripo chine huwandu hwepamusoro hwekugadzirisa magetsi uye kukwanisa kuchengetedza zvakanyanya zvakanyanya kupisa zvinogadzirwa munzvimbo inoda.
Iyi ficha inoderedza kurasikirwa kwesimba uye inonatsiridza iyo yese smelting process 'kushanda zvakanaka, zvichikonzera kushoma kwekushandisa simba uye kuderera kwemitengo yekugadzira.
Graphite Electrode Unique Properties
GRAPHITE ELECTRODE yakanakira kushandiswa mumagetsi arc furnaces uye mamwe maindasitiri ekushandisa.Iyo yakasarudzika midziyo inoita kuti graphite electrode ikwanise kumira tembiricha yakakwira inosvika 3,000 ° C kusvika uye kumanikidzwa mumagetsi arc furnace (EAF).
- High Thermal Conductivity- Graphite electrodes ine yakanakisa yekupisa conductivity, iyo inovagonesa kutsungirira kupisa kwakanyanya uye kumanikidza panguva yekunyungudika.
- Kuramba Kwemagetsi kwakaderera- Iko kuderera kwemagetsi kupikisa kwegraphite electrodes inofambisa kufamba nyore kwesimba remagetsi mumagetsi arc furnaces.
- High Mechanical Simba- Graphite electrode akagadzirirwa kuve neakakwira mechani simba rekumira nekushisa kwakanyanya uye mazinga ekumanikidza mumagetsi arc furnaces.
- Yakanakisa Chemical Resistance- Graphite chinhu chakanyanya inert chinoshingirira kumakemikari mazhinji uye zvinoparadza zvinhu.Graphite electrodes yakanakira kushandiswa munzvimbo dzakaomarara dzeindasitiri, uko zvimwe zvinhu zvinogona kukundikana nekuda kwekurwiswa kwemakemikari.
Graphite electrode haingoshandiswe zvakanyanya mumagetsi arc furnaces, zvakare inoshandiswa mukugadzira silicon simbi, yero phosphorus, uye mamwe asiri-ferrous simbi, acids, alkalis, uye mamwe makemikari, corrosive nharaunda.
Graphite electrodes inokamurwa kuita mamakisi matatu zvichienderana nehunhu hwawo, humbowo uye akasiyana maapplication ane chekuita nemagetsi evira remoto, transformer simba remutoro.Iwo anonyanya kushandiswa mamakisi emagraphite electrode ndeye Ultra-yakakwirira simba (UHP), High simba (HP), uye Regular simba (RP).
UHP graphite electrodes ine high thermal conductivity uye kuderera kwemagetsi kuramba, anonyanya kushandiswa kune ekupedzisira-akakwirira simba remagetsi arc furnace (EAF) mukunyungudutsa simbi yakanatswa kana simbi yakakosha. A patani.
HP Graphite Electrode ndiyo yakanakisa conductive zvinhu kune yemagetsi arc vira uye kunyungudutswa kwevira, inoita semutakuri kuunza ikozvino muchoto.HP graphite electrode inowanzo shandiswa kune yakakwirira simba remagetsi arc furnace(EAF) iyo inokwana inosvika 400kV/A. patani.
RP graphite electrode inoshandiswa zvakanyanya mumoto wemagetsi wenguva dzose iyo inokwana inenge 300kV / A patani kana zvishoma.R RP giredhi rine yakaderera thermal conductivity uye mechanical simba zvichienzaniswa UHP graphite electrode uye HP graphite electrode.RP graphite electrodes anonyanya kukodzera. yekugadzira simbi dzepasi-giredhi senge simbi, kunatsa silicon, kunatsa yero phosphorous, kugadzira maindasitiri egirazi.
Nekuwedzera kuri kuda kwemamwe magetsi masosi, magraphite electrode ari kuitawo basa rakakosha mukuvandudza masero emafuta.
Graphite electrodes ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana.Mamwe ekutanga mashandisirwo egraphite electrode anosanganisira;
Electric Arc Furnace (EAF) muKugadzira Simbi
Graphite electrode application muEAF steelmaking chinhu chakakosha chekugadzirwa kwemazuva ano kwesimbi.Graphite electrodes inoitwa se conductor kuendesa magetsi kuchoto, iyo inoburitsa kupisa kunyungudutsa simbi.Iyo EAF maitiro inoda kupisa kwakanyanya kunyungudutsa simbi yakaraswa, graphite electrodes inogona kumira kutonhora kwakanyanya pasina kurasikirwa kwechimiro chayo.Senyika. inoramba ichitarisa nzira dzakasimba uye dzakasimba dzekugadzira, magirafu emagetsi acharamba achiita basa rakakosha muEAF kugadzira simbi.
Ladle Furnace(LF)
Ladle furnaces(LFs) zvinhu zvakakosha zveSimbi-kugadzira Process.Graphite electrode inoshandiswa muindasitiri yeradle yevira kuti ipe magetsi epamusoro uye tembiricha yepamusoro mukati mekuita.Maelectrode egraphite ndeayo akanakisa maficha anosanganisira yakakwirira conductivity, kuramba kupisa kwemafuta uye kuparara kwemakemikari, uye hupenyu hurefu, ndiyo sarudzo yakakodzera yeladle furnace (LF) application.Nekushandisa magirafu emagetsi, vafambisi vechoto vanogona kuwana kunyatsoshanda, kubereka. uye kudhura-kushanda, uku uchichengetedza mazinga emhando yepamusoro anodiwa neindasitiri.
Gura reMagetsi rakanyura (SEF)
Graphite electrode inoshandiswa zvakanyanya muchoto chemagetsi chakanyura chinhu chakakosha mukugadzirwa kwesimbi zhinji uye zvinhu zvakaita seyero phosphorous, pure silicon.Graphite electrodes ndeyake yakanakisa ficha inosanganisira yakakwirira yemagetsi conductivity, yakakwira kuramba kuvhunduka kwekupisa, uye yakaderera coefficient yekuwedzera kwemafuta.Aya maficha anoita kuti graphite electrode yakanakira kushandiswa muchoto chemagetsi chakadzika, uko kutonhora kwakanyanya uye mamiriro akaomarara ndizvo zvinowanzoitika.
Graphite electrode zvinhu zvakakosha muElectric Arc Furnace (EAF) steelmaking process. Iyo graphite electrode inoshandisa yakakosha inodhura chinhu mukugadzirwa kwesimbi.Kusarudza giredhi rakakodzera uye saizi yegraphite electrode, pane zvakati wandei zvekufunga nezve chero application.
- Simbi mhando uye giredhi
- Burner uye oxygen tsika
- Chiyero chesimba
- Chiyero chazvino
- Kugadzirwa kwevira uye kugona
- Chaja zvinhu
- Target graphite electrode kushandiswa
Kusarudza yakakodzera graphite electrode yevira rako kwakakosha kuti uwane kuita kwakaringana, kuderedza kushandiswa kwesimba, uye kuderedza mari yekugadzirisa.
