ukwenza intsimbi

Inkcazo yokwenza intsimbi: susa ukungcola kwintsimbi yehagu kunye ne-scrap nge-oxidation kwaye ungeze inani elifanelekileyo lezinto ze-alloy ukuze wenze intsimbi enamandla amakhulu, ukuqina okanye ezinye iimpawu ezikhethekileyo.Le nkqubo ibizwa ngokuba yi "steelmaking".
Kwi-iron carbon alloys kunye nomxholo wekhabhoni ≤ 2.0%, ukubaluleka kwe-2.0% C kwi-iron carbon phase diagram.Ubushushu obuphezulu: i-austenite, intsebenzo entle eshushu;Ubushushu obuqhelekileyo: ikakhulu ipearlite.
Kutheni i-steelmaking: intsimbi yehagu ayinakusetyenziswa ngokubanzi.Umxholo wekhabhoni ophezulu: akukho austenite kwiqondo lokushisa eliphezulu;Ukusebenza kakubi: ukuqina kunye ne-brittle, ukuqina okungahambi kakuhle, ukusebenza kakubi kwe-welding, ayikwazi ukusetyenzwa;Ukungcola okuninzi: umxholo ophezulu we-S, P kunye nokubandakanywa.
Izinto eziqhelekileyo kwintsimbi: izinto ezintlanu: C, Mn, s, P kunye neSi (efunekayo).Ezinye izinto: V, Cr, Ni, Ti, Cu, njl. (ngokomgangatho wentsimbi).Izizathu ezikhoyo: ① unyino lwenkqubo: s kunye no-P abanakususwa ngokupheleleyo;② Intsalela yezinto ezikrwada: Intsalela ye-Scrap Cu, Zn;③ Iipropathi eziphuculweyo: UMn uphucula amandla kwaye iAl icoca ingqolowa.Umxholo wesiqalelo: ① iimfuno zomgangatho wesizwe: GB;② Umgangatho weshishini: umiselwa lishishini;③ Eminye imigangatho yelizwe: swrch82b (eJapan).
Umsebenzi oyintloko wokwenza intsimbi: umsebenzi ophambili wokwenza intsimbi kukucokisa isinyithi esinyibilikisiweyo kunye nentsimbi ye-scrap ibe yintsimbi kunye nokwakheka kweekhemikhali ezifunekayo, kwaye ibe neempawu ezithile ze-physicochemical and mechanical.Umsebenzi oyintloko ushwankathelwa ngokuthi "ukususwa okune, ukususwa kabini kunye nokulungiswa kabini".
4. I-decarbonization, i-desulfurization, i-dephosphorization kunye ne-deoxidation;
Ukususwa ezimbini: ukususa iigesi ezinobungozi kunye nokungcola;
Uhlengahlengiso ezimbini: lungisa ubushushu bentsimbi ye-liquid kunye nokwakheka kwe-alloy.
