1. Kukumba ndi kukonza chitsulo:
Pali mitundu iwiri ya hematite ndi magnetite yomwe imakhala ndi ntchito yabwino yosungunulira komanso mtengo wogwiritsa ntchito.
2. Kukumba ndi kuphika malasha:
Pakali pano, zoposa 95% ya zitsulo zopangidwa padziko lonse lapansi zimagwiritsabe ntchito njira yopangira chitsulo ya coke yomwe inayambitsidwa ndi British Darby zaka 300 zapitazo.Chifukwa chake, coke ndiyofunikira popanga chitsulo, chomwe chimagwiritsidwa ntchito kwambiri ngati mafuta.Pa nthawi yomweyi, coke imakhalanso yochepetsera.Chotsani chitsulo kuchokera ku iron oxide.
Coke si mchere, koma iyenera "kuyengedwa" posakaniza mitundu ina ya malasha.Chiŵerengero chambiri ndi 25-30% ya malasha amafuta ndi 30-35% ya malasha ophikira, kenako amawaika mu uvuni wa coke ndikukhala ndi mpweya kwa maola 12-24., kupanga coke wolimba ndi porous.
3. Kuwotcha chitsulo chamoto:
Kuphulika kwa ng'anjo ya ng'anjo ndiko kusungunula chitsulo ndi mafuta (coke ili ndi ntchito ziwiri, imodzi ngati mafuta, ina monga chochepetsera), miyala yamoto, ndi zina zotero, mu ng'anjo yophulika, kuti ichepetse kutentha kwakukulu. ndipo amachepetsedwa kuchokera ku iron oxide.Kutulutsa kwake kwenikweni ndi “chitsulo cha nkhumba” chopangidwa makamaka ndi chitsulo ndipo chimakhala ndi mpweya wina, kutanthauza chitsulo chosungunuka.
4. Kupanga chitsulo kukhala chitsulo:
Kusiyana kwakukulu pakati pa chitsulo ndi chitsulo ndi mpweya wa carbon, ndipo mpweya wa carbon ndi wosakwana 2% ndi "chitsulo" chenichenicho.Zomwe zimatchulidwa kuti "steelmaking" ndi decarburization ya chitsulo cha nkhumba panthawi yotentha kwambiri, kutembenuza chitsulo kukhala chitsulo.Zomwe zimagwiritsidwa ntchito popanga zitsulo ndi chosinthira kapena ng'anjo yamagetsi.
5. Kuponya billet:
Pakalipano, kuwonjezera pa kupanga zitsulo zapadera ndi zitsulo zazikuluzikulu zazitsulo, zitsulo zazing'ono zoponyedwa zitsulo zimafunika kuti zipangidwe.Kupanga kwakukulu kwazitsulo zamtundu wamba kunyumba ndi kunja kwenikweni kwasiya njira yakale yopangira zitsulo zachitsulo - billeting - rolling, ndipo ambiri a iwo amagwiritsa ntchito Njira yopangira zitsulo zosungunula mu billets ndiyeno kuzigudubuza kumatchedwa "kuponya mosalekeza" .
Ngati simukuyembekezera kuti billet yachitsulo izizire, musagwere panjira, ndikutumiza mwachindunji ku mphero, mukhoza kupanga zitsulo zofunika "pamoto umodzi".Ngati billet itakhazikika pakati ndikusungidwa pansi, billet ikhoza kukhala chinthu chogulitsidwa pamsika.
6. Billet atakulungidwa muzinthu:
Pansi pa kugubuduza mphero, billet imasintha kuchoka ku coarse kupita ku yabwino, kuyandikira pafupi ndi m'mimba mwake yomaliza ya mankhwala, ndipo imatumizidwa ku bedi lozizira la bar kuti lizizizira.Mipiringidzo yambiri imagwiritsidwa ntchito pokonza zida zamakina ndi zina zotero.
Ngati mipukutu yokhala ndi mawonekedwe imagwiritsidwa ntchito pamphero yomaliza yomaliza, ndizotheka kupanga rebar, zomwe zimatchedwa "rebar".
Zomwe zili pamwambazi zokhudzana ndi kupanga rebar, ndikuyembekeza kuti zidzakhala zothandiza kwa aliyense.
