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:
Ukwakhiwa kwensimbi yesithando somlilo ukuncibilikisa insimbi yensimbi kanye nophethiloli (i-coke inendima embaxambili, eyodwa njengophethiloli, 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 kwayiyeka 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 kumaholoholo ukuya kokucolile, isondela futhi isondela kububanzi bokugcina bomkhiqizo, futhi ithunyelwa kumbhede wokupholisa we-bar ukuze uphole. 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.
