Te hāoratanga owhakangaoKo te nuinga o nga mea e pa ana ki te hanganga matū o te whakarewa wera me nga mea o roto me waho o te mowhiti whakawera (pērā i te hanganga hau o te oumu, te wera whakawera, me etahi atu).
1) Te hanganga matū o nga mea whakarewa
Ko te nui o te tauine waikura i hanga e tata ana ki te hanganga matū.Ko te teitei ake o te waro o te maitai, ka iti ake te tauine waikura, ina koa ka nui ake te waro ki te 0.3%.Ko tenei na te mea i muri i te waro i te waikura, ka hangaia he papa o te hauwakura (CO) ki runga i te mata o te patea, e whai waahi ana ki te aukati i te waikura tonu.Alloy steel i roto i te Cr, Ni, Al, Mo, Si me etahi atu huānga, ka nui ake te whakamahana ina he iti te hanganga o te tauine, na te mea i oxidized enei huānga, ka taea te hanga i tetahi paparanga i runga i te mata o te kiriata waikura kiato maitai, a ka he tata te maitai ki te whakarea roha waiariki, me te piri ki te mata, ehara i te mea ngawari ki te pakaru me te taka atu, na reira ki te aukati i te whakamaaramatanga, te whakamarumaru.Heat-ātete maitai kore-tihore he koranu maitai ki atu o nga huānga i runga ake, a ka ko te ihirangi o Ni me Cr i roto i te maitai ko 13%?I te 20%, tata karekau he waikura ka puta.
2) Te hanganga hau umu
He nui te awe o te hanganga hau o te oumu ki te hanganga ote patupatutauine, rite tonuwhariki maitaii roto i te huru whakawera rerekē, te hanganga o te tauine he kore rite, i roto i te hau oumu oxidizing, te hanganga o te tauine ko te tino, hina hina, ngāwari ki te tango;I roto i te hau oumu kupapa (kei roto i te N2 te nuinga) me te hau o te oumu whakaheke (kei roto CO, H2, me etahi atu), he iti ake te pango o te tauine waikura i hangaia, kaore i te ngawari ki te tango.Hei whakaiti i te hanganga me te tango i te tauine waikura, me aro ki te mana o te hanganga hau o te oumu i ia wahanga o te whakamahana.I te nuinga o te korero, kei raro iho te 1000 ℃ te whakamakuku, ka whakamahia te hau o te oumu oxidized i te wa e whakamahana ana, na te mea kaore i te teitei te pāmahana i tenei wa, kaore i te tino kino te tukanga o te waikura, a he ngawari te tango i te tauine waikura i hangaia;Ka nui ake te pāmahana ki te 1000 ℃, ina koa i te waahi e pupuri ana i te pāmahana teitei, me whakamahi te whakaiti i te hau oumu, te hau oumu kore ranei hei whakaiti i te hanga o te tauine waikura.
Ko te ahua o te hau o te oumu i roto i te oumu whakawera mura e whakawhirinaki ana ki te nui o te hau e tukuna ana ki te wahie i te wa ngingiha.Mena he nui rawa te taikaha o te hau i roto i te oumu, he nui rawa te tuku o te hau, he oxidized te hau oumu, he nui ake te tauine waikura whakarewa, ki te 0.4 te taikaha o te hau i roto i te oumu?I te 0.5, ka whakahekehia te hau o te oumu, ka hangaia he hau whakamarumaru hei karo i te hanganga o te tauine waikura me te kore e taea te whakawera whakawera.

3) Te pāmahana whakawera
Ko te pāmahana whakawera hoki te take matua o te hanga i te tauine, te teitei ake o te pāmahana whakawera, te kaha ake o te waikura.I te 570 ℃?I mua i te 600 ℃, he puhoi te whakamau i te waikura, mai i te 700 ℃ te tere o te waiora ki te 900 ℃?I te 950 ℃, he tino nui te hāora.Mena ka whakaarohia te tere o te waikura ki te 1 ki te 900 ° C, 2 ki te 1000 ° C, 3.5 ki te 1100 ° C, me te 7 ki te 1300 ° C, ka piki ake kia ono nga wa.
4) Te wa whakawera
Ko te roa ake o te wa whakawera o te whakamahana i roto i te hau oxidizing i roto i te oumu, ka nui ake te whakamaaramatanga o te waikura, ka nui ake te hanga o te tauine waikura, ina koa i roto i te waahi whakamahana teitei o te wera, na me whakaiti te wa whakawera kia taea. , ina koa ko te wa whakawera me te wa e pupuri ana i te pāmahana teitei me whakapoto rawa atu.
I tua atu, ko te pire whakaipoipo i te teitei o te wera kaore i te oxidized anake i roto i te oumu, engari ano hoki i roto i te tukanga whakahiato, ahakoa kua horoia te tauine waikura i runga i te pire, ki te mea he tiketike tonu te pāmahana pire, ka rua nga wa ka oxidized, engari te ka ngoikore haere te tere hāora i te hekenga o te pāmahana pire.
