hana kila

Ka wehewehe o ka hana kila: wehe i nā mea haumia i loko o ka hao puaʻa a me ka ʻōpala e ka oxidation a hoʻohui i ka nui kūpono o nā mea hoʻohui e hoʻolilo iā ia i kila me ka ikaika kiʻekiʻe, ka paʻakikī a i ʻole nā ​​mea kūikawā ʻē aʻe.Kapa ʻia kēia hana ʻo "steelmaking".
No ka hao kalapona hao me ka kalapona maʻiʻo ≤ 2.0%, ke koʻikoʻi o 2.0% C i ka hao kalapona pae kiʻi.Kiʻekiʻe wela: austenite, maikaʻi wela hana hana;ʻO ka mahana maʻamau: ka nui o ka pearlite.
No ke aha e hana ai i ke kila: ʻaʻole hiki ke hoʻohana nui ʻia ka hao puaʻa.ʻO ke kalapona kiʻekiʻe: ʻaʻohe austenite i ka wela kiʻekiʻe;Hana maikaʻi ʻole: paʻakikī a palupalu, paʻakikī maikaʻi ʻole, maikaʻi ʻole ka hana kuʻi ʻana, hiki ʻole ke hana;Nui nā mea haumia: kiʻekiʻe maʻiʻo o S, P a me nā inclusions.
Nā mea maʻamau i ke kila: ʻelima mau mea: C, Mn, s, P a me Si (koi ʻia).Nā mea ʻē aʻe: V, Cr, Ni, Ti, Cu, etc. (e like me ke kila kila).Nā kumu e kū nei: ① ka palena o ke kaʻina hana: s a me P ʻaʻole hiki ke wehe loa ʻia;② Ke koena mea maka: E ʻoki koena Cu, Zn;③ Nā waiwai i hoʻomaikaʻi ʻia: Hoʻomaikaʻi ʻo Mn i ka ikaika a hoʻomaʻemaʻe ʻo Al i ka palaoa.ʻElemu maʻiʻo: ① koina maʻamau ʻāina: GB;② ʻO ke kūlana ʻoihana: hoʻoholo ʻia e ka ʻoihana;③ Nā kūlana aupuni ʻē aʻe: swrch82b (Iapana).
ʻO ka hana nui o ka hana kila: ʻo ka hana nui o ka hana kila, ʻo ia ka hoʻomaʻemaʻe ʻana i ka hao i hoʻoheheʻe ʻia a ʻokiʻoki i ke kila i ke kila me ka hoʻohui ʻia kemika, a loaʻa iā ia kekahi mau waiwai physicochemical a me mechanical.ʻO ka hana nui i hōʻuluʻulu ʻia ʻo "ʻehā wehe, ʻelua wehe a ʻelua hoʻoponopono".
4. Decarbonization, desulfurization, dephosphorization a me deoxidation;
ʻElua wehe: wehe i nā kinoea ʻino a me nā haumia;
ʻElua hoʻololi: hoʻoponopono i ka mahana kila wai a me ka hoʻohui ʻana.
