Le ndandatho yokukhanga ihlanganisa okokubumba okufana neringi emaphakathi, iringi yefeni, iringi encane yophawu, kanye neringi yokucindezelwa kwethangi lamanzi ye-turbine generator yesiteshi samandla samandla, kodwa ayifanele ukufojiswa kweringi okungewona ozibuthe.
Inqubo yokukhiqiza:
1 Ukuncibilika
1.1.Insimbi esetshenziselwa ukubumba kufanele inyibilikiswe esithandweni somlilo esine-alkaline.Ngemvume yomthengi, ezinye izindlela zokuncibilikisa ezifana ne-electro-slag remelting (ESR) nazo zingasetshenziswa.
1.2.Emafosheni ebanga lesi-4 noma ngaphezulu kanye nebanga lesi-3 anogqinsi olungaphezu kuka-63.5mm, insimbi encibilikisiwe esetshenzisiwe kufanele ifakwe ivacuum noma icwengwe ngezinye izindlela ukuze kukhishwe amagesi ayingozi, ikakhulukazi i-hydrogen.
2 Ukuqamba
2.1.Ingot ngayinye yensimbi kufanele ibe nesabelo esanele sokusika ukuze kuqinisekiswe ikhwalithi yokufoga.
2.2.Izigayo kufanele zenziwe emishinini yokunyathelisa, izando zokubumba, noma izigayo eziginqikayo ezinomthamo owanele ukuze kuqinisekiswe ukubunjwa okuphelele kwayo yonke ingxenye yensimbi futhi kuqinisekiswe ukuthi ingxenye ngayinye inesilinganiso esanele sokubumba.
3 Ukwelashwa kokushisa
3.1.Ngemuva kokuqedwa kokubumba, ama-forging kufanele afakwe ngokushesha ekwelapheni kokushisa, okungaba yi-annealing noma ukujwayelekile.
3.2.Ukwelashwa kokushisa kokusebenza kuyacisha futhi kuyabambisa (16Mn angasebenzisa ukujwayelekile kanye nokuthambisa).Izinga lokushisa lokugcina lokuthobisa le-forging akufanele libe ngaphansi kuka-560℃.
4 Ukwakheka kwamakhemikhali
4.1.Ukuhlaziywa kokwakheka kwamakhemikhali kufanele kwenziwe kuqoqo ngalinye lensimbi encibilikisiwe, futhi imiphumela yokuhlaziya kufanele ihambisane nezindinganiso ezifanele.
4.2.Ukuhlaziywa kokwakheka kwamakhemikhali omkhiqizo oqediwe kufanele kwenziwe ekufogeni ngakunye, futhi imiphumela yokuhlaziya kufanele ihambisane namazinga afanelekile.4.3.Lapho i-vacuum decarburizing, okuqukethwe kwe-silicon akufanele kudlule u-0.10%.4.4.Kumasongo eringi ebanga lesi-3 anogqinsi olungaphezu kuka-63.5mm, izinto zokwakha ezinokuqukethwe kwe-nickel ezingaphezu kuka-0.85% kufanele zikhethwe.
5 Izakhiwo zemishini
5.1.Izakhiwo zemishini ye-tangential ye-forging kufanele ihambisane nezindinganiso ezifanele.
6 Ukuhlola okungabhubhisi
6.1.Ama-forging akufanele abe nemifantu, izibazi, ukugoqa, izimbobo ezinciphayo, noma ezinye iziphambeko ezingavumelekile.
6.2.Ngemuva kokwenza imishini enembile, zonke izindawo kufanele zihlolwe yizinhlayiyana kazibuthe.Ubude bomugqa kazibuthe akufanele budlule u-2mm.
6.3.Ngemuva kokwelashwa kokushisa kokusebenza, ama-forgings kufanele ahlolwe nge-ultrasonic.Ububanzi obulinganayo bokuzwela kufanele bube ngu-φ2 mm, futhi iphutha elilodwa akufanele lidlule ububanzi obulinganayo φ4mm.Uma kunesici esisodwa phakathi kobubanzi obulinganayo obungu-φ2mm~¢4mm, akumele kube namaphutha angaphezu kwayisikhombisa, kodwa ibanga eliphakathi kwanoma yiziphi izici ezimbili eziseduze kufanele libe likhulu ngokuphindwe kahlanu kunobubanzi obukhulu besici, futhi inani lokunciphisa okubangelwa ukukhubazeka akufanele ngaphezu kuka-6 dB.Amaphutha adlula amazinga angenhla kufanele abikwe ekhasimendeni, futhi bobabili abathintekayo kufanele babonisane ngokuphathwa.
