Ezimpilweni zansuku zonke, abantu bahlala bebiza insimbi nensimbi ndawonye ngokuthi "insimbi". Kungabonakala ukuthi insimbi nensimbi kufanele kube uhlobo lwento; empeleni, ngokombono wesayensi, insimbi nensimbi zinokuhluka okuncane, izingxenye zazo eziyinhloko ziyinsimbi, kodwa inani lekhabhoni eliqukethwe lihlukile. Sivame ukubiza ngokuthi "insimbi yengulube" enokuqukethwe kwekhabhoni engaphezu kuka-2%, kanye "nensimbi" enokuqukethwe kwekhabhoni ngaphansi kwaleli nani. Ngakho-ke, ngesikhathi sokuncibilikisa insimbi nensimbi, insimbi enensimbi iqala inyibilikiswa ibe insimbi yengulube encibilikisiwe esithandweni somlilo (isithando somlilo), bese insimbi yengulube encibilikisiwe ifakwa esithandweni sokwenza insimbi ukuze icwengwe ibe yinsimbi. Khona-ke, insimbi (i-steel billet noma i-strip) isetshenziselwa ukwenza amapayipi ensimbi, isibonelo, ama-billet ensimbi ye-carbon angenziwa abe amapayipi ensimbi anezingxenye ezingenalutho ngokusebenzisa izinqubo zokuginqika ezishisayo nezibandayo (amashubhu e-carbon steel nekhono)

Inqubo yokukhiqiza amashubhu ensimbi engenamthungo ihlukaniswe kakhulu ngezinyathelo ezimbili ezinkulu:

1. Ukuginqika okushisayo (ishubhu lensimbi elingenamthungo elikhishiwe): ishubhu eliyindilinga billet → ukushisisa → ukubhoboza → ukugoqa okuphambanayo okungama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula → ukwenza usayizi (noma ukunciphisa) → ukupholisa → ukuqondisa → ukuhlolwa kwamanzi (noma ukutholwa kwamaphutha) → ukumaka → ukugcinwa kwempahla

2. Ishubhu lensimbi elibandayo elidonsayo (eligoqiwe) elingenamthungo: ishubhu eliyindilinga alinalutho→ukushisa→ukubhoboza→isihloko→ukulanda→ukucosha→ukugcoba→ukugcoba (ukucwebezela kwethusi)→umdwebo obandayo onamapayipi amaningi (ukuginqika okubandayo)→ithubhu elingenalutho→ukwelashwa kokushisa→ukuqondisa → i-hydrostatic ukuhlola (ukutholwa kwamaphutha) → ukumaka → isitoreji.
Izinto ezisetshenziswayo ezidingekayo ukuze kukhiqizwe insimbi nensimbi zihlukaniswe izigaba ezine futhi kuxoxwe ngazo ngokwehlukana: isigaba sokuqala sidingida izinto ezisetshenziswayo ezihlukahlukene ezinensimbi; isigaba sesibili sidingida amalahle necoke; Ukugeleza (noma ukugeleza) kwe-slag, njenge-limestone, njll.; isigaba sokugcina yizinto ezisetshenziswayo ezisizayo ezahlukahlukene, njengensimbi eyi-scrap, umoya-mpilo, njll.
