Ityhubhu ye-Copper-Nickel Alloy yePremium – Ukumelana namanzi olwandle okugqwesileyo
Ityhubhu yeCopper emhlophe (iCupro-Nickel) - Isongezelelo soBugcisa
Iityhubhu zethu ze-cupro-nickel zenziwe ngenkqubo elawulwa ngokupheleleyo yokuphosa ngokuqhubekekayo okuchanekileyo, ukusebenza ngokubandayo okuhamba ngeendlela ezininzi, kunye nonyango lobushushu bomoya okhuselayo ukuqinisekisa ukwakheka kwe-alloy efanayo, ulwakhiwo lweenkozo ezicociweyo, kunye nolwakhiwo oluxineneyo.
Ukuhamba kweenkqubo eziphambili: Ukunyibilika kwe-vacuum induction → Ukuphoswa okuthe tyaba (i-billet eqhubekayo) → Ukukhupha okushushu okuphezulu → Ukuqengqeleka/ukuzoba okubandayo okudlula ngeendlela ezininzi → Ukutsalwa kwe-annealing okuphakathi okuninzi phantsi kwe-atmosphere ekhuselayo → Ukugqitywa kokugqibela → Uvavanyo lwe-100% ye-eddy current + i-ultrasound (njengoko kufuneka).
Ulawulo lomgangatho ludlula ngokungqongqo imigangatho yesizwe neye-ASTM ngokweenkcukacha zangaphakathi:
● Ulwakhiwo lweekhemikhali: Ubushushu ngabunye buqinisekiswa yi-spectrometer yokufunda ngqo; utshintsho lwezinto eziphambili (Cu+Ni+Fe+Mn) lulawulwa ngaphakathi kwe-±0.05%
● Ubungakanani beenkozo: Zigcinwa rhoqo kwi-0.015–0.035 mm, akukho nkozo zixutyiweyo
● Iimpawu zoomatshini: Uvavanyo olupheleleyo lwamandla okutsalwa, amandla okukhupha, kunye nokwandiswa; i-coefficient of variation (CV) < 3%
● Ukunyamezelana kobukhulu: OD ± 0.015 mm, Ubunzima ± 0.008 mm, i-ovality ≤ 0.02 mm
● Ukugqitywa komphezulu: Umphezulu wangaphakathi nowangaphandle uRa ≤ 0.4 μm, awunambala we-oxidation, imikrwelo, okanye imifantu
● I-NDT: Uvavanyo lwangoku lwe-eddy oluyi-100% ngokwe-EN 1971 Class A; uvavanyo lwe-ultrasonic luyafumaneka xa luceliwe
● Ucoceko lwangaphakathi: Ucoceko lwangaphakathi lungcono kune-IGC-Test Grade 1, lufanelekile kwi-hydrogen enoxinzelelo oluphezulu, iifriji, kunye nezinye izinto ezibalulekileyo
Ezi tyhubhu zisetyenziswe ngokuthembekileyo kubunjineli bezolwandle, imibhobho yamanzi olwandle, izixhobo zokutshintsha ubushushu, imigca yezixhobo zamandla enyukliya, kunye neenkqubo zokugcina kunye nezothutho zehydrogen ezinoxinzelelo oluphezulu. Siye saseka ubudlelwane bexesha elide bokubonelela ngeenkampani ezininzi eziphambili kushishino kwaye sigcina umthamo wonyaka weetoni ezingama-8,000 zeetyhubhu ze-cupro-nickel ezisebenza kakuhle. Imveliso eyenziwe ngokwezifiso ngokwemizobo yabathengi okanye imigangatho efana ne-AMS 4574, CuNi30, C71500, BNi-2, njl.njl., iyafumaneka.
