Njerwa zokhala ndi mpweya wokwanira zimamaliza kuyenga chitsulo chosungunula, chifukwa chake ndizofunikira
Njerwa zopumira malizitsani kuyenga kwa chitsulo chosungunuka, chifukwa chake ndikufunika kwake
Kuwombera mpweya wosowa (monga argon) pansi pa njerwa yopumira yomwe imatha kupumira imatha kuphulitsa mpweya ndi zosafunika mu chitsulo chosungunuka, chomwe chitha kufanana kapangidwe kake ndi kutentha kwa chitsulo chosungunuka, chomwe ndichofunikira kwambiri pakuyeretsa chitsulo chosungunuka. Kuyenga kwa ng’anjo ndi njira yopangira chitsulo momwe chitsulo chosungunuka choyambirira chimasinthidwa, moto wotseguka kapena ng’anjo yamagetsi imasamutsidwa ku chotengera china choyenga, chotchedwanso “chitsulo chachiwiri”.
Kuuzira mpweya wosowa (monga argon) mpaka pansi pa njerwa yopumira yomwe imatha kupumira imatha kuwononga mpweya ndi zosafunika mu chitsulo chosungunuka, chomwe chitha kufanana kapangidwe kake ndi kutentha kwa chitsulo chosungunuka, chomwe ndichofunikira kwambiri pakuyeretsa chitsulo chosungunuka. Kuyenga kwa ng’anjo ndi njira yopangira chitsulo momwe chitsulo chosungunuka choyambirira chimasinthidwa, moto wotseguka kapena ng’anjo yamagetsi imasamutsidwa ku chotengera china choyenga, chotchedwanso “chitsulo chachiwiri”. Chifukwa chake, kupanga zitsulo kumagawika magawo awiri: kuyenga koyambirira ndi kuyenga. Kuyenga kwa ng’anjo kumaphatikizapo: kusinthanso ndikuyeretsa kutentha, kapangidwe kake, gasi, zinthu zoyipa ndi kuphatikiza kwa chitsulo chosungunuka mu ladle kuti chikwaniritse ukhondo, kufanana ndi kukhazikika; Kulimbikitsa akuyandama mpweya ndi inclusions mu tundish ndi, Akhazikitse ndi kutentha chitsulo chosungunula pa ndondomeko zonse kuponyera.

Ukadaulo ndi zida za ntchito yoyeretsa kunja kwa ng’anjo zimakwaniritsidwa: kugwiritsa ntchito njerwa zopumira kupititsa argon poyambitsa gasi, kapena kuyambitsa magetsi; kuwonjezeredwa kwa zinthu zophatikizika, ma deoxidizers ndi ma slag modifiers kudzera pamakina oyendetsa; Zipangizo zolimba; kudyetsa mawaya aloyi mu ladle; matekinoloje osiyanasiyana a zingalowe; Kutentha chitsulo chosungunuka m’ng’anjo yamafuta; chitsulo luso otaya chitetezo.
Njira zomwe amagwiritsidwa ntchito moyesa kunja kwa ng’anjo zitha kugawidwa m’magulu awiri: mtundu wa kukonza ladle ndi mtundu wa ladle woyenga. LF kuyenga kwamoto ndi imodzi mwanjira zazikulu zoyesera kunja kwa ng’anjo. Kuchotsa zingwe ndi njira yoyeretsa zitsulo zamtengo wapatali zomwe zikugwiritsidwa ntchito pano. RH ndi VD amagwiritsidwa ntchito kwambiri. Mwa zina, njira ya AOD ndikupanga chitsulo chosapanga kaboni ndi mpweya wotsika kwambiri wokhala ndi mpweya pansi pamavuto am’mlengalenga, ndipo sichopanda zingwe chomwe chimagwiritsidwa ntchito kwambiri posungunula chitsulo chosapanga dzimbiri. Njira ya VOD ndiukadaulo wowotchera m’ng’anjo yopanga chitsulo chosapanga dzimbiri cha chromium pophulika ndi mpweya ndikuwotcha pansi pazinthu zopumira ndikuwombera argon mozungulira. , Ndi njira yopanda zingwe komanso zingalowe m’malo mwazitsulo zosapanga dzimbiri.
