Chubu cha Aloyi cha Copper-Nickel cha Premium – Kukana Kwambiri Madzi a M'nyanja

Chubu Choyera cha Mkuwa (Cupro-Nickel) - Chowonjezera Chaukadaulo

Machubu athu a cupro-nickel amapangidwa kudzera mu njira yowongoleredwa bwino kwambiri yopangira zinthu molunjika molunjika, kugwira ntchito mozizira modutsa njira zambiri, komanso kutentha koteteza mlengalenga kuti zitsimikizire kuti zinthuzo zimagwirizana, kapangidwe ka tirigu woyengedwa bwino, komanso kapangidwe kakang'ono kwambiri.

Kuyenda kwa njira yofunikayi: Kusungunuka kwa vacuum induction → Kuponyedwa kosalekeza kopingasa (semi-continuous billet) → Kutulutsa kotentha kwambiri → Kugubuduza/kujambula kozizira kopitilira muyeso → Kuphimba kwapakati kwapakati pansi pa mlengalenga woteteza → Kumaliza komaliza → Kuyesa kwa 100% eddy current + ultrasound (monga momwe zimafunikira).

Kuwongolera khalidwe kumaposa miyezo ya dziko lonse ndi ASTM ndi zofunikira zamkati:

● Kapangidwe ka mankhwala: Kutentha kulikonse komwe kumatsimikiziridwa ndi spectrometer yowerengera mwachindunji; kusintha kwa zinthu zazikulu (Cu+Ni+Fe+Mn) kumayendetsedwa mkati mwa ±0.05%
● Kukula kwa tirigu: Kusungidwa nthawi zonse pa 0.015–0.035 mm, palibe tirigu wosakaniza
● Kapangidwe ka makina: Kuyesa kwathunthu kwa mphamvu yokoka, mphamvu yotulutsa, ndi kutalika; coefficient of variation (CV) < 3%
● Kulekerera kwa miyeso: OD ± 0.015 mm, WT ± 0.008 mm, ovality ≤ 0.02 mm
● Kumaliza pamwamba: Pamwamba ndi panja Ra ≤ 0.4 μm, yopanda utoto wa okosijeni, mikwingwirima, kapena ming'alu
● NDT: Kuyesa kwa 100% kwa eddy current motsatira EN 1971 Class A; kuyesa kwa ultrasound kulipo ngati mupempha
● Ukhondo wamkati: Ukhondo wamkati uli bwino kuposa IGC-Test Giredi 1, woyenera kugwiritsa ntchito hydrogen yamphamvu, ma refrigerant, ndi zinthu zina zofunika kwambiri

Machubu awa agwiritsidwa ntchito modalirika mu uinjiniya wa m'madzi, mapaipi amadzi a m'nyanja, zosinthira kutentha, zingwe zamagetsi a nyukiliya, ndi makina osungira ndi mayendedwe a hydrogen okhala ndi mphamvu yayikulu. Takhazikitsa ubale wautali ndi makampani ambiri otsogola m'makampani ndipo timasunga mphamvu ya matani 8,000 pachaka a machubu a cupro-nickel ogwira ntchito bwino. Kupanga mwamakonda malinga ndi zojambula za makasitomala kapena miyezo monga AMS 4574, CuNi30, C71500, BNi-2, ndi zina zotero, kulipo.
