Inqubo yokukhiqiza ye-rebar ikakhulukazi ihlanganisa izinyathelo ezi-6 ezinkulu:
1. Ukumbiwa nokucutshungulwa kwensimbi yensimbi:
Kunezinhlobo ezimbili ze-hematite ne-magnetite ezinokusebenza okungcono kokuncibilika kanye nenani lokusebenzisa.
2. Ukumbiwa kwamalahle nokupheka:
Njengamanje, ngaphezu kwama-95% okukhiqizwa kwensimbi emhlabeni kusasebenzisa indlela yokwenza i-coke iron eyasungulwa yi-British Darby eminyakeni engama-300 edlule.Ngakho-ke, i-coke iyadingeka ekwenzeni insimbi, esetshenziswa kakhulu njengophethiloli.Ngesikhathi esifanayo, i-coke nayo iyi-ejenti yokunciphisa.Khipha insimbi ku-iron oxide.
I-coke ayiyona iminerali, kodwa kufanele “icwengwe” ngokuxuba izinhlobo ezithile zamalahle.Isilinganiso esijwayelekile singama-25-30% wamalahle anamafutha kanye nama-30-35% amalahle okupheka, bese efakwa kuhhavini ye-coke bese efakwa i-carbonized amahora angu-12-24., ukwakha i-coke eqinile futhi enezimbotshana.
3. Ukwenziwa kwensimbi yesithando somlilo:
Ukwenziwa kwensimbi yesithando somlilo ukuncibilikisa insimbi yensimbi kanye nophethiloli (i-coke inendima embaxambili, enye iwukubasa, enye njenge-ejenti yokunciphisa), i-limestone, njll., esithandweni somlilo, ukuze ibhekane nokusabela kokunciphisa izinga lokushisa eliphezulu. futhi iyancipha kusuka ku-iron oxide.Okuphumayo ngokuyisisekelo “insimbi yengulube” ngokuyinhloko eyakhiwe ngensimbi futhi iqukethe ikhabhoni ethile, okungukuthi, insimbi encibilikisiwe.
4. Ukwenza insimbi ibe yinsimbi:
Umehluko oyisisekelo phakathi kwezakhiwo zensimbi nensimbi okuqukethwe kwekhabhoni, futhi okuqukethwe kwekhabhoni kungaphansi kuka-2% "insimbi" yangempela.Okuvame ukubizwa ngokuthi "ukwenza insimbi" ukuchithwa kwensimbi yengulube ngesikhathi senqubo yokuncibilikisa izinga lokushisa eliphezulu, ukuguqula insimbi ibe yinsimbi.Imishini esetshenziswa kakhulu yokwenza insimbi iyisiguquli noma isithando somlilo sikagesi.
5. Ukusakaza i-billet:
Njengamanje, ngaphezu kokukhiqizwa kwensimbi ekhethekile kanye ne-castings yensimbi enkulu, inani elincane le-ingots yensimbi ephonsiwe liyadingeka ekusetshenzisweni kokucubungula.Ukukhiqizwa okukhulu kwensimbi evamile ekhaya nakwamanye amazwe ngokuyisisekelo kuye kwayishiya inqubo endala yokuphonsa izinsimbi zensimbi - i-billeting - rolling, futhi iningi lazo lisebenzisa Indlela yokuphonsa insimbi encibilikisiwe ibe amabhilidi bese iwagingqa ibizwa ngokuthi "ukusakaza okuqhubekayo" .
Uma ungalindi ukuthi i-billet yensimbi iphole, ungahlali endleleni, futhi uyithumele ngokuqondile emshinini wokugaya, ungenza imikhiqizo yensimbi edingekayo "emlilweni owodwa".Uma i-billet ipholiswe phakathi futhi igcinwe phansi, i-billet ingaba yimpahla ethengiswa emakethe.
6. Ibhilidi eligoqelwe emikhiqizweni:
Ngaphansi kokuginqika komshini wokugaya, i-billet iyashintsha ukusuka kokumahhadlahhadla ukuya kokucolile, isondela ngokusondela kububanzi bokugcina bomkhiqizo, futhi ithunyelwa kumbhede wokupholisa webha ukuze iphole.Iningi lamabha asetshenziselwa ukucubungula izingxenye zesakhiwo semishini nokunye.
Uma amaroli anephethini asetshenziswa kugayo lokugcina lokuqedela ibha, kungenzeka ukukhiqiza i-rebar, into yesakhiwo ebizwa ngokuthi "i-rebar".
Isingeniso esingenhla mayelana nenqubo yokukhiqiza ye-rebar, ngithemba ukuthi kuzoba usizo kuwo wonke umuntu.
