Inkqubo yemveliso ye-rebar ikakhulu ibandakanya amanyathelo ama-6 amakhulu

Inkqubo yemveliso ye-rebar ikakhulu ibandakanya amanyathelo ama-6 amakhulu:

1. Ukwembiwa kwentsimbi kunye nokulungiswa:
Kukho iintlobo ezimbini ze-hematite kunye ne-magnetite ezinomsebenzi ongcono wokunyibilikisa kunye nexabiso lokusebenzisa.

2. Ukwembiwa kwamalahle kunye nokupheka:

Okwangoku, ngaphezulu kwe-95% yemveliso yentsimbi yehlabathi isasebenzisa indlela yokwenza i-coke iron eyasungulwa yiBritish Darby kwiminyaka engama-300 eyadlulayo. Ngoko ke, i-coke iyadingeka ekwenzeni isinyithi, esetyenziswa kakhulu njengamafutha. Ngexesha elifanayo, i-coke nayo i-arhente yokunciphisa. Khupha i-iron kwi-iron oxide.

I-coke ayiyominerali, kodwa kufuneka "icocwe" ngokuxuba iindidi ezithile zamalahle. Umlinganiselo oqhelekileyo ngu-25-30% wamalahle e-fat kunye ne-30-35% ye-coking coal, uze ufake kwi-oven ye-coke kunye ne-carbonized iiyure eziyi-12-24. , ukwenza i-coke eqinile kunye ne-porous.

3. Ukwenziwa kwentsimbi kwiziko eliqhumayo:

Ukwenziwa kwentsimbi yesithando somlilo kukunyibilikisa intsimbi ekrwada kunye namafutha (i-coke inendima emibini, enye njenge-fuel, enye njenge-agent yokunciphisa), i-limestone, njl., kwisithando somlilo, ukwenzela ukuba ifumane ukusabela kokunciphisa kwiqondo lokushisa eliphezulu. kwaye iyancipha kwi-iron oxide. Ngokusisiseko imveliso “yintsimbi yehagu” ubukhulu becala yenziwe yintsimbi yaye inekhabhoni, oko kukuthi, intsimbi enyibilikisiweyo.

4. Ukwenza intsimbi ibe yintsimbi:

Umahluko osisiseko phakathi kweempawu zentsimbi kunye nentsimbi ngumxholo wekhabhoni, kwaye umxholo wekhabhoni ungaphantsi kwe-2% "yentsimbi" yangempela. Into ebizwa ngokuqhelekileyo ngokuthi "i-steelmaking" yi-decarburization yentsimbi yehagu ngexesha lokunyibilika kobushushu obuphezulu, ukuguqula intsimbi ibe yintsimbi. Izixhobo ezisetyenziswa ngokuqhelekileyo zokwenza i-steelmaking yi-converter okanye i-furnace yombane.

5. Ukuphosa ibhilethi:

Okwangoku, ukongeza kwimveliso yentsimbi ekhethekileyo kunye neentsimbi ezinkulu, i-ingots yensimbi encinci iyadingeka kwi-forging processing. Ukuveliswa kweentsimbi eziqhelekileyo ekhaya nakwamanye amazwe ngokusisiseko kuye kwayishiya inkqubo endala yokuphosa i-ingots yensimbi - i-billeting - rolling, kwaye ininzi yabo isebenzisa Indlela yokuphosa insimbi etyhidiweyo kwiibhilithi kwaye emva koko iqhube ibizwa ngokuba yi "continuous casting" .

Ukuba awulindeli ukuba i-billet yensimbi ipholile, musa ukuhlala endleleni, kwaye uyithumele ngokuthe ngqo kwi-rolling mill, unokwenza iimveliso zetsimbi ezifunekayo "emlilweni omnye". Ukuba i-billet ipholile phakathi kwaye igcinwe emhlabeni, i-billet ingaba yimpahla ethengiswa kwimarike.

6. Ibhilethi iqengqeleke kwiimveliso:

Ngaphantsi kwe-rolling ye-rolling mill, i-billet iyatshintsha ukusuka kwi-coarse ukuya kwi-fine, isondela kwaye isondele kwi-diameter yokugqibela yemveliso, kwaye ithunyelwa kwi-bar yokupholisa ibhedi yokupholisa. Uninzi lweebhari zisetyenziselwa ukusetyenzwa kwamalungu omatshini kunye nokunye.

Ukuba i-pattered rolls isetyenziswe kwi-bar yokugqibela yokugqiba i-mill, kunokwenzeka ukuvelisa i-rebar, i-structural material ebizwa ngokuthi "i-rebar".

Isingeniso esingentla malunga nenkqubo yokuvelisa i-rebar, ndiyathemba ukuba iya kuba luncedo kumntu wonke.
