Ukwakha i-rotor yama-industrial turbines

1. Ukuncibilika

1.1 Ukuze kukhiqizwe izingxenye ezifojiwe, ukuncibilikiswa kwesithando somlilo esine-alkaline esilandelwa ukucwengisiswa kwangaphandle kuyatuswa ezingots zensimbi. Ezinye izindlela zokuqinisekisa ikhwalithi nazo zingasetshenziselwa ukuncibilikisa.

1.2 Ngaphambi noma ngesikhathi sokuphonswa kwama-ingots, insimbi kufanele ikhishwe nge-vacuum degassing.

2. Ukuqamba

2.1 Izici eziyinhloko zokuguquguquka phakathi nenqubo yokubumba kufanele zikhonjiswe kumdwebo wenqubo yokubumba. Isibonelelo esanele sokusika kufanele sinikezwe emaphethelweni angaphezulu naphansi engot yensimbi ukuze kuqinisekiswe ukuthi ingxenye ehlanganisiwe ayinakho ukufakwa kwe-slag, imigodi yokuncipha, i-porosity, kanye nokukhubazeka okunzima kokuhlukaniswa.

2.2 Amathuluzi okufoja kufanele abe nomthamo owanele wokuqinisekisa ukungena okuphelele kwaso sonke isigaba esiphambanayo. I-eksisi yengxenye efojiwe kufanele iqondaniswe eduze ngangokunokwenzeka ne-axial centerline yengot yensimbi, okungcono ukukhetha isiphetho se-ingot yensimbi enekhwalithi engcono yesiphetho se-turbine drive.

3. Ukwelashwa kokushisa

3.1 Ukwelashwa kwe-post-forging, normalizing kanye nokushisa kufanele kwenziwe.

3.2 Ukusebenza kokwelashwa kokushisa kufanele kwenziwe ngemuva komshini onzima.

3.3 Ukusebenza kokwelashwa kokushisa kubandakanya ukucisha kanye nokushisa futhi kufanele kwenziwe kume mpo.

3.4 Izinga lokushisa lokushisa lokucisha ngesikhathi sokwelashwa kokushisa kokusebenza kufanele libe ngaphezu kwezinga lokushisa lokuguqulwa kodwa lingadluli ku-960 ℃. Izinga lokushisa lokushisa akufanele libe ngaphansi kuka-650 ℃, futhi ingxenye kufanele ipholiswe kancane ibe ngaphansi kuka-250 ℃ ngaphambi kokususwa esithandweni. Izinga lokupholisa ngaphambi kokususwa kufanele libe ngaphansi kuka-25 ℃/h.

4. Ukwelashwa okwehlisa ingcindezi

4.1 Ukwelashwa okwehlisa ingcindezi kufanele kwenziwe umphakeli, futhi izinga lokushisa kufanele libe phakathi kuka-15 ℃ kuya ku-50 ℃ ngaphansi kwezinga lokushisa langempela. Kodwa-ke, izinga lokushisa lokwelashwa okunciphisa ukucindezeleka akufanele libe ngaphansi kuka-620 ℃.

4.2 Ingxenye efojiwe kufanele ibe sendaweni eqondile ngesikhathi sokwelashwa okudambisa ingcindezi.

5. Ukushisela

Ukushisela akuvunyelwe ngesikhathi sokukhiqiza nokupakisha.

6. Ukuhlolwa nokuhlolwa

Amathuluzi namandla okwenza izivivinyo mayelana nokwakheka kwamakhemikhali, izakhiwo zemishini, ukuhlolwa kwe-ultrasonic, ingcindezi eyinsalela, nezinye izinto ezishiwo kufanele kuhambisane nezivumelwano zobuchwepheshe ezifanele kanye namazinga.
