Umuyoboro w'icyuma cya nikeli w'agaciro kanini – Ubudahangarwa bw'amazi yo mu nyanja buhanitse cyane
Umuyoboro w'umuringa wera (Cupro-Nickel) - Inyongeramusaruro ya tekiniki
Imiyoboro yacu ya cupro-nickel ikorwa binyuze mu buryo bugenzurwa neza bwo gucukura neza mu buryo butambitse, gukoresha uburyo bwinshi bwo gukonjesha, no gushyushya ikirere kugira ngo habeho imiterere imwe y’ibumba, imiterere y’ibinyampeke byatunganyijwe, n’imiterere mito y’uturemangingo.
Uburyo bw'ingenzi bukoreshwa: Gushonga mu buryo bw'umwuka → Guca mu buryo butambitse (billet ikomeza) → Gusohora amazi mu buryo bushyushye cyane → Gutembera/gushushanya mu buryo bukonje inshuro nyinshi → Guteranya amazi mu buryo bubiri hagati munsi y'ikirere kirinda → Gusoza → Gupima 100% by'umuraba ushyushye + ikizamini cya ultrasound (niba bikenewe).
Igenzura ry’ubuziranenge rirenze cyane amahame y’igihugu n’ay’icyitegererezo cya ASTM hamwe n’ibipimo byayo:
● Imiterere ya shimi: Buri bushyuhe bwemejwe na spectrometer isoma mu buryo butaziguye; ihindagurika ry'ibintu by'ingenzi (Cu+Ni+Fe+Mn) rigenzurwa muri ± 0.05%
● Ingano y'ibinyampeke: Iguma ibungabunzwe kuri mm 0.015–0.035, nta binyampeke bivanze
● Imiterere ya mekanike: Isuzuma ryuzuye ry'imbaraga zo gukurura, imbaraga zo gukuraho, n'uburebure; igipimo cy'ihindagurika (CV) < 3%
● Ubushobozi bwo kwihanganira ingano: OD ± 0.015 mm, Uburemere ± 0.008 mm, oblite ≤ 0.02 mm
● Irangi ry'ubuso: Imbere n'inyuma Ra ≤ 0.4 μm, nta ibara ry'ubushyuhe, iminkanyari, cyangwa imivuniko irimo
● NDT: Isuzuma rya eddy current 100% kuri EN 1971 Class A; isuzuma rya ultrasound riraboneka iyo ubisabye
● Isuku y'imbere: Isuku y'imbere iruta IGC-Test Grade 1, ikwiriye gukoreshwa mu gushyushya hidrojeni, firigo, n'ibindi bikoresho by'ingenzi
Iyi miyoboro yakoreshejwe neza mu buhanga bwo mu mazi, imiyoboro y'amazi yo mu nyanja, imiyoboro y'ubushyuhe, imiyoboro y'amashanyarazi ya kirimbuzi, hamwe na sisitemu yo kubika no gutwara hydrogen ifite umuvuduko mwinshi. Twashinze umubano w'igihe kirekire n'ibigo byinshi bikomeye mu nganda kandi dukomeza ubushobozi bwo gutanga toni 8.000 buri mwaka bw'imiyoboro ya cupro-nickel ikora neza. Ikorwa ryihariye hakurikijwe ibishushanyo cyangwa amahame y'abakiriya nka AMS 4574, CuNi30, C71500, BNi-2, nibindi, rirahari.
