Ibha yeBronze ejikeleze i-Aluminium enamandla aphezulu i-C95400 – iCast Alloy

Ibha yeBronze yeNi-Al (C95800 / CuAl10Fe5Ni5-C) – Iinkcukacha zeMveliso yoBugcisa

Le nto iveliswa ngokuphoswa okuqhubekayo okanye okuqhubekekayo kulandele ukuphoswa okushushu okuhamba ngeendlela ezininzi kunye neenkqubo zokuzoba/zokugqiba ezibandayo ukuqinisekisa ulwakhiwo oluxineneyo, olungenazo iimbobo kunye nokufakwa kwezinto ezingezizo ezesinyithi, kunye nobukhulu obufanayo beenkozo. Ulwakhiwo lweekhemikhali lulawulwa ngokuqinileyo ngaphakathi kwe-±0.15% kwizinto ezibalulekileyo (Ni, Al, Fe) ngokuhambelana ngokupheleleyo ne-ASTM B148, EN 1982, okanye GB/T 12225, kunye nokungcola okupheleleyo okungaphantsi kwe-0.10%.

Ulawulo lomgangatho olupheleleyo lwenkqubo luyaphunyezwa

● Ukunyibilika kwenziwa kwi-induction furnace ephakathi kunye ne-flux covering kunye ne-argon shielding; umxholo we-oxygen <10 ppm;
● Uvavanyo lwe-100% lwe-ultrasonic lwee-billets ze-cast (ngokwe-ASTM B584 Class 1);
● Ukufakelwa kwesisombululo esiphindwe kathathu + unyango lobushushu obudala emva kokukhupha ukuze kuphuculwe ukusasazwa kwesigaba se-α kunye ne-κ, kufezekiswe ubunzima obuhambelanayo be-HB180-240;
● Ibhetshi nganye iphantsi koxinzelelo, ukugqwala, uvavanyo lwe-intergranular corrosion (ASTM G110), uvavanyo lwe-stress corrosion (ASTM G36/G44), kunye nokuhlolwa komntu wesithathu (SGS/Pony) kunye nesatifikethi se-3.1 ngokwe-EN 10204.

Iimpawu eziqhelekileyo (φ30-200 mm)

● Amandla okutsalwa ≥ 690 MPa
● Amandla okuvelisa ≥ 330 MPa
● Ukwandiswa ≥ 12%
● Izinga lokugqwala kwamanzi olwandle ≤ 0.02 mm/ngonyaka (okulinganayo neminyaka engama-40)

Ifanelekile kwiipropellers zaselwandle ezinzima, iziqu zeevalvu, iishafts zepompo ezinamandla aphezulu ezingamelani nokugqwala, kunye nezixhobo ezibalulekileyo zesakhiwo ezivezwe emanzini olwandle kwiindawo zaselwandle naselwandle.

Siziingcali ekunikezeni ubhedu lwe-nickel-aluminium olukumgangatho ophezulu, olulandeleka ngokupheleleyo kumashishini amakhulu ekwakheni iinqanawa, kumashishini amakhulu, kumaqonga angaphandle, nakumacandelo e-petrochemical. Ubungakanani beloti buyi-50-300 yeetoni, kunye nokukwazi ukwenza izivumelwano zexesha elide eziqinisekisa ukwakheka okuzinzileyo kunye neempawu zoomatshini.
