Maitiro Akakosha Emusika
Kuwedzera Kugadzirwa kweSimbi kuburikidza neTekinoroji yeElectric Arc Furnace
- Chitofu chemagetsi chinotora simbi yakapwanyika, DRI, HBI (simbi inopisa yakapwanyika, iyo yakapwanyika DRI), kana simbi yenguruve muchimiro chakasimba, chozvinyungudutsa kuti zvigadzire simbi. Munzira yeEAF, magetsi anopa simba rekunyungudutsa chikafu.
- Graphite electrode inonyanya kushandiswa mukugadzira simbi yemagetsi (EAF) steel process, kunyungudutsa tsvina yesimbi. Maelectrode anogadzirwa negraphite nekuda kwekugona kwayo kutsungirira tembiricha yakakwira. MuEAF, muromo weelectrode unogona kusvika 3,000º Fahrenheit, inova hafu yetembiricha yezuva. Saizi yemaelectrode inosiyana zvakanyanya, kubva pa75mm mudhayamita, kusvika pa750mm mudhayamita, uye kusvika 2,800mm muhurefu.
- Kukwira kwemitengo yemaelectrode egrafiti kwakawedzera mitengo yemagayo eEAF. Avhareji yeEAF inofungidzirwa kuti inoshandisa maelectrode egrafiti angangoita 1.7 kg kuti igadzire tani imwe chete yesimbi.
- Kukwira kwemitengo kunokonzerwa nekusimbiswa kwemaindasitiri, pasi rose, kudzimwa kwesimba muChina, zvichitevera mitemo yezvakatipoteredza, uye kukura kwekugadzirwa kweEAF, pasi rose. Izvi zvinofungidzirwa kuti zvichawedzera mutengo wekugadzirwa kweEAF ne1-5%, zvichienderana nemaitiro ekutenga emuchina, uye izvi zvingangoderedza kugadzirwa kwesimbi, sezvo pasina chinotsiva graphite electrode mumabasa eEAF.
- Pamusoro pezvo, mitemo yeChina yekugadzirisa kusvibiswa kwemhepo yakasimbiswa nemiganhu yakasimba yekugovera, kwete chete chikamu chesimbi, asiwo marasha, zinc, nedzimwe nzvimbo dzinogadzira kusvibiswa kwezvikamu. Nekuda kweizvozvo, kugadzirwa kwesimbi muChina kwakadzikira zvakanyanya mumakore apfuura. Zvisinei, izvi zvinotarisirwa kuva nemigumisiro yakanaka pamitengo yesimbi nemidziyo yekugadzira simbi munharaunda iyi, kuti ive nemari iri nani.
- Zvinhu zvese zvataurwa pamusoro apa, zvinotarisirwa kutungamira musika we graphite electrode munguva yekufanotaura.
Dunhu reAsia-Pacific richatonga Musika
- Dunhu reAsia-Pacific ndiro rakatonga musika wepasi rose. China ndiyo ine mugove mukuru pakushandiswa uye kugona kwekugadzira ma graphite electrodes pasi rose.
- Mutemo mutsva wemutemo muBeijing nedzimwe nzvimbo huru munyika unomanikidza vagadziri vesimbi kuvhara simba rematani mamiriyoni 1.25 esimbi inogadzirwa nenzira inokuvadza nharaunda kuitira kuti vagadzire simba idzva rematani miriyoni imwe esimbi. Mitemo yakadaro yakatsigira kuchinja kwevagadziri kubva munzira dzemazuva ano dzekugadzira simbi kuenda kunzira yeEAF.
- Kuwedzera kuri kuita kugadzirwa kwemotokari, pamwe chete neindasitiri yekuvaka dzimba dziri kukura, zvinotarisirwa kutsigira kudiwa kwemidziyo yesimbi isina ferrous uye simbi, izvo zviri chinhu chakanaka pakukura kwekudiwa kwe graphite electrode mumakore anotevera.
- Kugona kwekugadzira ma electrode e UHP graphite pari zvino muChina kunosvika zviuru makumi mashanu zve metric ton pagore. Kudiwa kwema electrode e UHP muChina kunotarisirwawo kuona kukura kukuru kwenguva refu uye huwandu hwekuwedzera hwema metric ton anopfuura zviuru makumi mashanu ema electrode e UHP graphite hunotarisirwa kuonekwa muzvikamu zvinotevera zvenguva yekufanotaura.
- Zvinhu zvese zvataurwa pamusoro apa, zvinotarisirwawo kuwedzera kudiwa kwe graphite electrode munharaunda iyi munguva yekufanotaura.
