1.2 Asanayambe kapena akuponya ma ingots, chitsulocho chiyenera kutsekedwa ndi vacuum degassing.
2. Kunyenga
2.1 Makhalidwe akuluakulu osinthika panthawi yopanga zinthu akuyenera kuwonetsedwa muzojambula.Chilolezo chokwanira chodula chiyenera kuperekedwa kumtunda ndi kumunsi kwa ingot yachitsulo kuti zitsimikizire kuti gawo lopangidwa ndi lopanda slag inclusions, shrinkage cavities, porosity, ndi zolephereka kwambiri za tsankho.
2.2 Zida zopangira zida ziyenera kukhala ndi mphamvu zokwanira kuti zitsimikizire kuti gawo lonselo likulowa.Mzere wa gawo lopangidwira uyenera kugwirizanitsa mozama momwe zingathere ndi axial centerline ya ingot yachitsulo, makamaka kusankha mapeto a ingot yachitsulo ndi khalidwe labwino la turbine drive end.
3. Chithandizo cha kutentha
3.1 Chithandizo cha post-forging, normalizing ndi tempering chiyenera kuchitidwa.
3.2 Ntchito kutentha mankhwala ayenera kuchitidwa pambuyo Machining akhakula.
3.3 Kuchita chithandizo cha kutentha kumaphatikizapo kuzimitsa ndi kutentha ndipo kuyenera kuchitidwa moyima.
3.4 Kutentha kwa kutentha kwa kuzimitsa panthawi ya chithandizo cha kutentha kuyenera kukhala pamwamba pa kutentha kwa kusintha koma osapitirira 960 ℃.Kutentha kwa kutentha sikuyenera kukhala pansi pa 650 ℃, ndipo gawolo liyenera kukhazikika pang'onopang'ono mpaka pansi pa 250 ℃ musanachotsedwe mu ng'anjo.Kuzizira kusanachotsedwe kuyenera kukhala kosakwana 25 ℃/h.
4. Chithandizo chochepetsa kupsinjika
4.1 Chithandizo chochepetsera nkhawa chiyenera kuchitidwa ndi wogulitsa, ndipo kutentha kuyenera kukhala mkati mwa 15 ℃ mpaka 50 ℃ pansi pa kutentha kwenikweni.Komabe, kutentha kwa mankhwala ochepetsa nkhawa sikuyenera kukhala pansi pa 620 ℃.
4.2 Gawo lopukutidwa liyenera kukhala loyimirira panthawi yamankhwala ochepetsa nkhawa.
5. Kuwotcherera
Kuwotcherera sikuloledwa panthawi yopanga ndi kulongedza.
6. Kuyendera ndi kuyesa
Zida ndi kuthekera koyesa mayeso pamakina, makina amakina, kuyang'anira akupanga, kupsinjika kotsalira, ndi zinthu zina zomwe zatchulidwazi ziyenera kutsata mapangano oyenerera ndi miyezo.
