Ibisobanuro byo gukora ibyuma: kuvanaho umwanda mubyuma byingurube no gusiba ukoresheje okiside hanyuma wongereho urugero rukwiye rwibintu bivangwa kugirango ube icyuma gifite imbaraga nyinshi, gukomera cyangwa nibindi bidasanzwe.Iyi nzira yitwa "gukora ibyuma".
Kubyuma bya karubone byuma birimo karubone ≤ 2.0%, akamaro ka 2.0% C mubishushanyo mbonera bya karubone.Ubushyuhe bwo hejuru: austenite, imikorere myiza ishyushye;Ubushyuhe busanzwe: ahanini pearlite.
Impamvu gukora ibyuma: ibyuma byingurube ntibishobora gukoreshwa cyane.Ibirimo byinshi bya karubone: nta austenite ku bushyuhe bwinshi;Imikorere idahwitse: ikomeye kandi yoroheje, ubukana bubi, imikorere mibi yo gusudira, idashobora gutunganya;Umwanda mwinshi: ibintu byinshi bya S, P hamwe nibisobanuro.
Ibintu bisanzwe mubyuma: ibintu bitanu: C, Mn, s, P na Si (bisabwa).Ibindi bintu: V, Cr, Ni, Ti, Cu, nibindi (ukurikije urwego rwicyuma).Impamvu ziriho: lim imipaka igarukira: s na P ntibishobora kuvaho burundu;Res Ibisigazwa by'ibikoresho bisigaye: Ibisigazwa by'ibisigazwa Cu, Zn;Properties Kunoza imitungo: Mn itezimbere imbaraga na Al itunganya ingano.Ibigize ibice: requirements ibisabwa bisanzwe byigihugu: GB;Standard Ibipimo ngenderwaho: bigenwa na rwiyemezamirimo;③ Ibindi bipimo byigihugu: swrch82b (Ubuyapani).
Igikorwa nyamukuru cyo gukora ibyuma: umurimo wingenzi wo gukora ibyuma ni ugutunganya ibyuma bishongeshejwe hamwe nicyuma gisakara mubyuma hamwe nibisabwa bya chimique, kandi bikagira bimwe mubintu bya fiziki na chimique.Igikorwa nyamukuru cyavuzwe muri make nk "gukuraho bine, gukuraho kabiri no guhinduka kabiri".
4. Decarbonisation, desulfurizasiya, dephosifora na deoxidation;
Gukuraho kabiri: gukuraho imyuka yangiza n’umwanda;
Ibintu bibiri byahinduwe: hindura ubushyuhe bwibyuma byamazi hamwe nibigize amavuta.
