Ubomi bemihla ngemihla, abantu bahlala bebhekisela kwintsimbi kunye nentsimbi kunye "njengentsimbi". Inokubonwa ukuba intsimbi kunye nentsimbi kufuneka ibe luhlobo oluthile; enyanisweni, ngokwembono yesayensi, intsimbi kunye nentsimbi zineeNzantyana ezincinci, iinxalenye zazo eziphambili ziyintsimbi, kodwa inani lekhabhoni eliqulethwe lihlukile. Ngokuqhelekileyo sibiza "i-pig iron" enomxholo wekhabhoni ngaphezu kwe-2%, kunye "nentsimbi" enomxholo wekhabhoni ngaphantsi kweli xabiso. Ngoko ke, kwinkqubo yokunyibilikisa intsimbi kunye nentsimbi, intsimbi enentsimbi iqala inyibilikiswa ibe yintsimbi yehagu etyhidiweyo kwisithando somlilo (isithando somlilo), emva koko intsimbi yehagu etyhidiweyo ifakwe kwiziko lentsimbi ukuze icocwe ibe yintsimbi. Emva koko, insimbi (i-steel billet okanye i-strip) isetyenziselwa ukwenza iibhobho zetsimbi, umzekelo, iibhilidi ze-carbon steel zingenziwa kwimibhobho yetsimbi enamacandelo angenalutho ngokusebenzisa iinkqubo ezitshisayo kunye ne-cold rolling (i-carbon steel seamless tubes)

Inkqubo yokwenziwa kweetyhubhu zentsimbi ezingenamthungo yahlulwe kakhulu yangamanyathelo amabini amakhulu:

1. Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo): ityhubhu engqukuva yebillet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukuhluba → ukwenza ubungakanani (okanye ukunciphisa) → ukupholisa → ukulungisa → uvavanyo lwehydraulic (okanye ukubona isiphene) → ukuphawula → ugcino

2. Ityhubhu yentsimbi ebandayo ezotyiweyo (eqengqelekayo): ityhubhu engqukuva blank→ukufudumeza→ukugqobhoza→isihloko→unyuso→ukuchola→ukuthambisa→ukufakwa kweoli (icwecwe lobhedu)→umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo)→umbhobho ongenanto→unyango lobushushu→ukuqondisa →ihydrostatic uvavanyo (ukubona iziphene) → ukuphawula → ugcino.
Izinto ezifunekayo zokuvelisa isinyithi kunye nentsimbi zihlulwe zibe ziindidi ezine kwaye zixutyushwa ngokwahlukileyo: udidi lokuqala luxubusha izinto ezahlukeneyo ezinentsimbi; udidi lwesibini luxoxa ngamalahle kunye necoke; I-flux (okanye i-flux) ye-slag, njenge-limestone, njl. udidi lokugqibela zizinto ezahlukeneyo zokuncedisa ekrwada, njengentsimbi ye-scrap, ioksijini, njl.
