Izinto Ezenziwayo:
20MnNi kanye ne-20MnNi.
Izici zikaMechanical:
Ngobukhulu bokubumba (T) obuphakathi kuka-300mm <T ≤ 500mm, into engu-20MnNi kufanele ibe namandla okukhiqiza ≥ 265MPa, amandla aqinile ≥ 515MPa, ubude ngemva kokuphuka ≥ 21%, ukuncishiswa kwendawo ≥ 35% ye-sorption, umthelela we-absorption ) ≥ 30J, futhi akukho mifantu ngesikhathi sokugoba okubandayo.
Ngobukhulu bokubumba (T) obungaphezu kuka-200mm, into engu-25MnNi kufanele ibe namandla okukhiqiza ≥ 310MPa, amandla aqinile ≥ 565MPa, ubude ngemva kokuphuka ≥ 20%, ukuncishiswa kwendawo ≥ 35%, amandla okumunca umthelela (0≥3) , futhi akukho mifantu ngesikhathi sokugoba okubandayo.
Ukuhlola Okungonakali:
Izindlela ezihlukile zokuhlola ezingabhubhisi ezifana nokuhlolwa kwe-ultrasonic (UT), ukuhlolwa kwezinhlayiya kazibuthe (MT), ukuhlolwa kwe-liquid penetrant (PT), nokuhlola okubonakalayo (VT) kufanele kwenziwe ezifundeni ezihlukahlukene ze-shaft forging eyinhloko ngezigaba nezimo ezihlukahlukene. .Izinto zokuhlola kanye nenqubo yokwamukela kufanele ihambisane namazinga afanele.
Ukwelashwa Kwamaphutha:
Ukukhubazeka okweqile kungasuswa ngokugaya ngaphakathi kwebanga lemvume yomshini.Kodwa-ke, uma ukujula kokususwa kwesici kudlula i-75% yesibonelelo sokuqeda, ukulungiswa kwe-welding kufanele kwenziwe.Ukulungisa iphutha kufanele kuvunywe yikhasimende.
Umumo, Ubukhulu, Nokuqina Kobuso:
Inqubo yokuqamba kufanele ihlangabezane nezidingo zobukhulu kanye nobulukhuni obucaciswe kumdwebo we-oda.Ubulukhuni bobuso bendingilizi yangaphakathi (inani lika-Ra) lokuqamba kufanele kucutshungulwe umphakeli ukuze kufinyelele ku-6.3um.
Ukuncibilika: Ama-ingots ensimbi okwenziwa ngawo kufanele akhiqizwe ngokuncibilika kwesithando somlilo sikagesi bese sicolisiswa ngaphandle kwesithando somlilo ngaphambi kokukhishwa kwe-vacuum.
Forging: Izibonelelo ezanele zokusika kufanele zinikezwe ekugcineni kwe-sprue kanye nesikhuphukeli sensimbi yensimbi.I-Forging kufanele yenziwe emishinini yokunyathelisa enekhono ukuze kuqinisekiswe ukuguquguquka okwanele kwepulasitiki yaso sonke isigaba sesiphambano se-forging.Kunconywa ukuthi kube nesilinganiso sokubumba esikhulu kuno-3.5.I-forging kufanele isondele eduze komumo nobukhulu bokugcina, futhi imigqa emaphakathi ye-ingot ye-forging nensimbi kufanele ihambisane kahle.
Ukwelashwa Kokushisa Kwezakhiwo: Ngemuva kokufoja, i-forging kufanele ibhekane nokwelashwa okufudumele noma okujwayelekile kanye nokushisa ukuze kutholwe isakhiwo esifanayo nezakhiwo.Izinga lokushisa elincane elishisayo akufanele libe ngaphansi kuka-600°C.
Uma udinga ulwazi olwengeziwe mayelana nama-WELONG forgings wegiya elikhulu neringi yegiya, sicela usazise.
