Inqubo yokukhiqiza ye-rebar ngokuyinhloko ifaka izinyathelo ezi-6 ezinkulu

Inqubo yokukhiqiza i-rebar ngokuyinhloko ifaka izinyathelo ezi-6 ezinkulu:

1. I-Iron Ore Mining kanye nokucubungula:
Kunezinhlobo ezimbili ze-hematite ne-magnetite ezinokusebenza okungcono kokunye ukunsunduza kanye nenani lokusebenzisa.

2. Imayini yamalahle nokukhangisa:

Njengamanje, ngaphezu kwama-95% okukhiqizwa kwensimbi emhlabeni kusasebenzisa indlela yokwenza i-coke yensimbi eyasungulwa yiBritish Darby eminyakeni engama-300 edlule. Ngakho-ke, iCoke iyadingeka ekwenzeni insimbi, esetshenziswa kakhulu njengophethiloli. Ngasikhathi sinye, uCoke futhi ungummeli oncishisiwe. Ususa insimbi kusuka ku-iron oxide.

I-Coke akuyona amaminerali, kepha kumele "icwengeke" ngokuxuba izinhlobo ezithile zamalahle. Isilinganiso esijwayelekile singama-25-30% amalahle amalahle kanye nama-30- 35% amalahle e-coking, bese afakwa kuhhavini we-coke kanye nama-carbonis amahora angu-12-24. , kwakha i-coke enzima ne-porous.

3. I-Blast Funece Ironmaking:

Ukwesabisa i-iron morace ukuncibilikisa i-iron ore nophethiloli (i-coke inendima embaxambili, enye njengabaphethiloli, enye njenge-ejenti yokunciphisa), i-limestone, njll. Esithandweni sokuncipha kwamazinga okushisa aphezulu futhi incishisiwe kusuka ku-iron oxide. Ukukhishwa ngokuyisisekelo "ingulube yengulube" ikakhulukazi yakhiwa ngensimbi futhi iqukethe ikhabhoni ethile, okungukuthi, insimbi ebilisiwe.

4. Ukwenza insimbi ibe yinsimbi:

Umehluko oyisisekelo phakathi kwezindawo zensimbi nensimbi ukuqukethwe kwekhabhoni, futhi okuqukethwe kwekhabhoni kungaphansi kwama-2% yi- "nsimbi" yangempela. Okuvame ukubizwa nge- "Steelmaking" ukushukumisa ama-decorralization we-Iron yengulube ngesikhathi senqubo ephezulu yokushintshana kwezinga lokushisa, iguqula insimbi ibe ngensimbi. Imishini eyenziwe yensimbi esetshenziswayo esetshenziswayo iyi-converter noma isithando sikagesi.

5. Ukuphonsa imali:

Njengamanje, ngaphezu kokukhiqizwa kwensimbi ekhethekile kanye ne-casts yensimbi enkulu, inani elincane le-cast amangots liyadingeka ukuze kwenziwe ukucubungula. Ukukhiqizwa okuphezulu kwensimbi ejwayelekile ekhaya nakwamanye amazwe sekushiywe ngokuyisisekelo inqubo endala yokuphonsa ama-ingots wensimbi - ukudlala - ukugoqa, futhi iningi lawo lisebenzisa indlela yokuphonsa incishisiwe ngamabhiliyoni " .

Uma ungalindi ukuthi i-billet yensimbi ibe yehle, ungangeni ndawo, futhi uyithumele ngokuqondile ku-Rolling Mille, ungenza imikhiqizo yensimbi edingekayo "emlilweni owodwa". Uma i-billet ipholile phakathi nendawo futhi igcinwe emhlabathini, imali ekhokhwayo ingaba yimpahla ethengiswa emakethe.

I-6. I-Billt igoqelwe kwimikhiqizo:

Ngaphansi kokugoqa kwesigayo esigoqisayo, izinguquko ezinkulu ezivela kusuka ekuhlanganeni kuya kokulungile, ukusondela futhi zisondela kububanzi bokugcina bomkhiqizo, futhi kuthunyelwa embhedeni opholile webha yokupholisa. Iningi lemigoqo isetshenziselwa ukucubungula izingxenye ezakhiwe ngokwenziwe ngomshini nokunye.

Uma kusetshenziswa ama-roll amaphethini esigangeni sokugcina sokuqeda ibha, kungenzeka ukukhiqiza ukwakhiwa kabusha, izinto ezibizwa nge- "rebar".

Ukwethulwa okungenhla mayelana nenqubo yokukhiqiza ye-rebar, ngithemba ukuthi kuzosiza wonke umuntu.
