WELONG shaft forgings ye-hydro-generator enkulu

Izinto ezibunjiweyo:

I-20MnNi kunye ne-20MnNi.

Iinkcazelo ngoomatshini:

Ngobunzima bokubumba (T) phakathi kwe-300mm <T ≤ 500mm, i-material 20MnNi kufuneka ibe namandla esivuno ≥ 265MPa, amandla okuqina ≥ 515MPa, ubude emva kokwaphuka ≥ 21%, ukunciphisa indawo ≥ ≥ ≥ 35% ye-absorp, impembelelo yamandla ) ≥ 30J, kwaye akukho zintanda ngexesha lokugoba okubandayo.

Kubunzima bokubumba (T) obungaphezulu kwe-200mm, izinto ezingama-25MnNi kufuneka zibe namandla esivuno ≥ 310MPa, amandla okuqina ≥ 565MPa, ubude emva kokwaphuka ≥ 20%, ukunciphisa indawo ≥ 35%, impembelelo yokufunxa amandla (0≥3) , kwaye akukho zintanda ngexesha lokugoba okubandayo.

Uvavanyo olungangonakalisi:

Iindlela ezahlukeneyo zovavanyo ezingonakalisi ezifana novavanyo lwe-ultrasonic (UT), uvavanyo lwemagnethi (MT), uvavanyo lokungena kulwelo (PT), kunye nokuhlolwa okubonakalayo (VT) kufuneka lwenziwe kwimimandla eyahlukeneyo yeshaft ephambili yokwenziwa kumanqanaba kunye neemeko ezahlukeneyo. .Izinto zokuvavanya kunye neendlela zokwamkelwa kufuneka zihambelane nemigangatho efanelekileyo.

Unyango Lweziphene:

Iziphene ezigqithisileyo zinokususwa ngokusila ngaphakathi koluhlu lwesibonelelo somatshini.Nangona kunjalo, ukuba ubunzulu bokususwa kwesiphene budlula i-75% yesibonelelo sokugqiba, ukulungiswa kwe-welding kufuneka kwenziwe.Ukulungiswa kwesiphene kufuneka kuvunywe ngumthengi.

Imilo, iDimension, kunye noBurhabaxa boMphezulu:

Inkqubo yokubumba kufuneka ihlangabezane neemfuno zobukhulu kunye noburhabaxa bomphezulu obuchazwe kumzobo woodolo.Uburhabaxa bomphezulu wesangqa sangaphakathi (ixabiso le-Ra) lokubunjwa kuya kucutshungulwa ngumthengisi ukufikelela kwi-6.3um.

Ukunyibilika: Ii-ingots zentsimbi zokubumba kufuneka ziveliswe ngokunyibilika kwesithando sombane kwaye emva koko zicocwe ngaphandle kwesithando somlilo phambi kokuphoswa kwevacuum.

Ukuqulunqa: Izibonelelo ezifanelekileyo zokusika kufuneka zinikezelwe kwi-sprue kunye neziphelo zokunyuka kwe-ingot yensimbi.Ukuqulunqa kufuneka kwenziwe kumatshini wokushicilela okwaziyo ukuqinisekisa ukuguqulwa okwaneleyo kweplastiki yecandelo elinqamlezayo lokubumba.Kucetyiswa ukuba ube ne-forging ratio enkulu kune-3.5.I-forging kufuneka isondele ngokusondeleyo kwimilo yokugqibela kunye nemilinganiselo, kwaye i-centerlines ye-forging kunye ne-ingot yensimbi kufuneka ihambelane kakuhle.

Ukunyangwa kobushushu kwiiPropati: Emva kokwenziwa, ukubunjwa kufuneka kuqhutywe ubushushu okanye unyango oluqhelekileyo kunye nokufudumala ukufumana ukwakheka okufanayo kunye neepropati.Ubuncinci bobushushu bobushushu akufunekanga bube ngaphantsi kwama-600°C.

Ukuba ufuna ulwazi oluthe kratya malunga ne-WELONG forgings yegiya enkulu kunye neringi yegiya, ngobubele usazise.
