Nakuba ngamunyei-graphite electrodeiwucezu oluthuthukisiwe lwemishini kanye nohlelo lokulawula oluhle kakhulu, kusafanele lusetshenziswe ngokwezimo zokukhiqiza kanye nezimo zangempela.Ngakho-ke, abantu bebelokhu besebenzela ukuthuthukisa ukusebenza kahle kokukhiqizwa kwe-graphite electrode.Ukwenza insimbi ye-graphite electrode kuye kwavela endleleni yokuncibilikisa engabizi kakhulu engakhiqiza kuphela inani elincane lensimbi yezinga lezentengiselwano kuya kubuchwepheshe bokuncibilikisa obungakhiqiza amamaki ahlukahlukene kanye nensimbi yekhwalithi ephezulu.

Njengoba nje isigayo ngasinye sensimbi sihlukile futhi SIZINDLELA ezimweni ezithile zokukhiqiza ezifana nezimo zokuthutha namandla, i-electrode ye-graphite ngayinye ihlukile.Abasebenzisi bahlose ukuhlangabezana namazinga enqubo athile, ngakho-ke bavumelanisa izindlela zabo zokukhiqiza nezimo zendawo noma zemakethe.Lokhu akusho ukuthi i-graphite-electrode steelmaking ayinalo ikusasa.Ngokuphambene, abaklami be-graphite electrode baye benza izinhlobonhlobo zama-graphite electrode ukuze bathuthukei-graphite electrodeukwenza insimbi, eziningi zazo ezifakiwe noma ezisetshenziswayo.

Ukulawula ukudla

Izindleko zokushaja (i-scrap, insimbi encishisiwe eqondile, insimbi eshisayo) ingaba yisici esiyinhloko esithinta izindleko ze-graphite electrode steelmaking.Ngakho-ke, abakhiqizi abaningi be-graphite electrode ukuze bathole ikhwalithi yomkhiqizo othile futhi bafune izindleko ezingcono zokukhiqiza, ngokushintshana bashintshe imodi yokushaja.

Inqubo ye-EAF kanye nobuchwepheshe be-BOF

Ngokushesha nje lapho isithando somlilo sigcwaliswa ngensimbi eshisayo, phezulu ngokushesha kuqala ukuvuthela umoya-mpilo ukuze kukhishwe ikhabhoni insimbi encibilikisiwe.Ngemuva kokuthi isigaba se-decarbonization sesiphelile, isibhamu se-oxygen sisuswa ngokushesha esithandweni futhi ama-electrode avele afakwe ngokushesha.Engeza isipholile se-DRI ekunikezeni amandla ngokuqhubekayo.Isigaba sesibili yisigaba sokucwenga kanti isithando somlilo siyisigaba sesibili.Ngakho-ke, isikhundla se-graphite electrode silungiselelwa isithando somlilo sesibili, futhi insimbi ingakhiqizwa kuphela ngemva kokuba ukucwengwa kuqediwe esithandweni somlilo.
