Imveliso ye-ingot
1. Isinyithi esinyibilikisiweyo senziwe ngokunyibilika kwesinyithi kunye ne-coke (i-carbon-rich substance eyenza xa amalahle eshushu xa kungekho moya) kwisithando somlilo, emva koko isusa i-carbon eninzi ngokuqhumisa i-oksijini emanzini.Intsimbi enyibilikisiweyo igalelwa kwizibonda zentsimbi ezinkulu nezingqindilili, apho iye iphole ibe ziingots.
2. Ukuze wenze iimveliso ezisicaba ezifana neepleyiti kunye namaphepha, okanye iimveliso ezinde ezifana nemivalo kunye neentonga, iingots zenziwe phakathi kweerola ezinkulu phantsi koxinzelelo olukhulu. Ukuvelisa iintyatyambo kunye namacwecwe
3. Ukuvelisa i-bloom, i-ingot idlula kwi-roller ye-grooved steel rollers ehlanganiswe.Ezi ntlobo ze-roller zibizwa ngokuba "zii-mill-high-high".Kwezinye iimeko, kusetyenziswa i-roller ezintathu.Ii-roller zifakwe ukwenzela ukuba i-grooves yazo ihambelane, kwaye ihamba ngeendlela ezichaseneyo.Esi senzo sibangela ukuba intsimbi icinezelwe kwaye yolulwe ibe ngamaqhekeza amancinci, amade.Xa i-roller iguqulwa ngumqhubi womntu, intsimbi itsalwa ngasemva ngokuyenza ibe yincinci kwaye ibe yinde.Le nkqubo iphinda iphindwe kuze kube yilapho intsimbi ifezekisa imo efunekayo.Ebudeni bale nkqubo, oomatshini ababizwa ngokuba zii-manipulators flip intsimbi ukuze icala ngalinye licutshungulwe ngokulinganayo.
4. Ii-ingots zinokuthi zifakwe kwi-slabs kwinkqubo efana nenkqubo yokwenza i-bloom.Intsimbi igqithiswa kwiirola ezipakishweyo eziyolula.Nangona kunjalo, kukho ii-roller ezifakwe kwicala lokulawula ububanzi bee-slabs.Xa intsimbi ifumana ubume obufunwayo, iziphelo ezingalinganiyo ziyanqunyulwa kwaye i-slabs okanye iintyatyambo zinqunyulwa zibe ngamaqhekeza amancinci.
5. Iintyatyambo zilungiswa ngakumbi phambi kokuba zenziwe zibe yimibhobho.Iiblooms ziguqulwa zibe ziibhilithi ngokuzifaka kwizixhobo eziqengqelekayo ezizenza zibe nde kwaye zibe mxinwa.Iibhilithi zisikwa zizixhobo ezaziwa ngokuba zizikere ezibhabhayo.Ezi zipere ezidityanisiweyo ezibaleka kunye nebhilethi eshukumayo kwaye ziyinqumle.Oku kuvumela ukusikwa okusebenzayo ngaphandle kokumisa inkqubo yokuvelisa.Ezi billets zipakishwe kwaye ekugqibeleni ziya kuba ngumbhobho ongenamthungo.
6. Ii-slabs nazo ziyasetyenzwa kwakhona.Ukuze zibe lula, ziqale zifudunyezwe zibe yi-2,200° F (1,204° C).Oku kubangela ukugquma kwe-oxide kwi-slab ebusweni.Olu gquba luqhawukile ngeqhekeza lesikali kunye nokutshiza kwamanzi ngoxinzelelo oluphezulu.Amacwecwe ke athunyelwa ngothotho lweerola kwisingqusho esishushu aze enziwe abe yimicu ebhityileyo yentsimbi ebizwa ngokuba yi-skelp.Eli sila linokuba lide kangangesiqingatha semayile.Njengoko ii-slabs zidlula kwii-roller, ziba zincinci kwaye zide.Kwisithuba esimalunga nemizuzu emithathu i-slab enye inokuguqulwa ukusuka kwi-6 kwi-(15.2 cm) yentsimbi eshinyeneyo ukuya kwiribhoni yentsimbi ebhityileyo enokuba yikota yeemayile ubude.
7. Emva kokwelula, intsimbi ixutywe.Le nkqubo ibandakanya ukuyiqhuba ngoluhlu lweetanki eziqulethe i-asidi ye-sulfuric ukucoca isinyithi.Ukugqiba, ihlanjululwe ngamanzi abandayo nashushu, yomiswe kwaye emva koko ihlanganiswe kwi-spools enkulu kwaye ipakishwe ukuze ihanjiswe kwindawo yokwenza umbhobho.
8. Zombini i-skelp kunye neebhilethi zisetyenziselwa ukwenza imibhobho.I-Skelp yenziwe kumbhobho odityanisiweyo.Iqala ibekwe kumatshini wokukhulula.Njengoko i-spool yentsimbi ingabonakali, iyafudumala.Emva koko intsimbi idluliswa kuluhlu lwe-grooved rollers.Njengoko idlula, i-roller ibangela ukuba imiphetho ye-skelp idibanise.Oku kwenza umbhobho ongadityaniswanga.
9. Intsimbi elandelayo idlula nge-electrode ye-welding.Ezi zixhobo zitywina iziphelo zombini zombhobho kunye.Umthungo odityanisiweyo ugqithiswa kwi-roller yoxinzelelo oluphezulu olunceda ukudala i-weld eqinile.Umbhobho ke emva koko usikwe kubude obufunwayo kwaye upakishwe ukuze kuqhutyekwe phambili.Umbhobho wensimbi odityanisiweyo yinkqubo eqhubekayo kwaye kuxhomekeke kubukhulu bombhobho, unokwenziwa ngokukhawuleza kwe-1,100 ft (335.3 m) ngomzuzu.
10. Xa ipayipi engenamthungo iyadingeka, iibhilidi zesikwere zisetyenziselwa ukuvelisa.Ziyafudunyezwa kwaye zibunjwe ukwenza i-cylinder shape, ebizwa ngokuba yingqukuva.Umjikelo ke ufakwa kwiziko apho kufudunyezwe mhlophe-shushu.Umjikelo ofudumeleyo ke uqengqwa ngoxinzelelo olukhulu.Olu xinzelelo oluphezulu lubangela ukuba i-billet yolule kwaye umngxuma wenze phakathi.Kuba lo mngxuma ubume ngendlela engaqhelekanga, indawo yokugqobhoza emile okwembumbulu ityhalelwa embindini webillet njengoko iqengqeleka.Emva kwenqanaba lokubhoboza, umbhobho usenobunzima obungaqhelekanga kunye nokumila.Ukulungisa oku kugqithwa kolunye uthotho lwee-mills.Ukuqhubekeka kokugqibela
