Ishubhu ye-Copper-Nickel Alloy ye-Premium – Ukumelana Okuphezulu Namanzi Olwandle
Ishubhu Lethusi Elimhlophe (i-Cupro-Nickel) - Isengezo Sobuchwepheshe
Amashubhu ethu e-cupro-nickel akhiqizwa ngenqubo elawulwa ngokuphelele yokuphonswa okuqhubekayo okuqondile okuphezulu, ukusebenza okubandayo okudlula izikhathi eziningi, kanye nokwelashwa kokushisa komkhathi ovikelayo ukuqinisekisa ukwakheka kwe-alloy okufanayo, isakhiwo sokusanhlamvu okucwengisisiwe, kanye nesakhiwo esincane esiminyene.
Ukugeleza kwenqubo ebalulekile: Ukuncibilika kokufakwa kwe-vacuum → Ukuphonswa okuqhubekayo okuvundlile (i-billet eqhubekayo kancane) → Ukukhishwa okushisayo kwesilinganiso esiphezulu → Ukugoqa/ukudweba okubandayo okudlula kaningi → Ukunamathisela okuphakathi okuningi ngaphansi komkhathi ovikelayo → Ukuqeda kokugcina → Ukuhlolwa kwamanje kwe-eddy okungu-100% + ukuhlolwa kwe-ultrasonic (njengoba kudingeka).
Ukulawulwa kwekhwalithi kudlula ngokuqinile amazinga kazwelonke kanye ne-ASTM ngezincazelo zangaphakathi:
● Ukwakheka kwamakhemikhali: Ukushisa ngakunye kuqinisekiswa yi-spectrometer yokufunda ngqo; ukuhlukahluka kwezinto ezinkulu (Cu+Ni+Fe+Mn) kulawulwa ngaphakathi kwe-±0.05%
● Usayizi wezinhlamvu: Kugcinwa njalo ku-0.015–0.035 mm, akukho zinhlamvu ezixubile
● Izakhiwo zemishini: Ukuhlolwa okuphelele kwamandla okudonsa, amandla okukhiqiza, kanye nokwelulwa; i-coefficient of variation (CV) < 3%
● Ukubekezelelana kobukhulu: OD ±0.015 mm, WIT ±0.008 mm, ovality ≤ 0.02 mm
● Ukuphela kobuso: Ubuso bangaphakathi nobangaphandle i-Ra ≤ 0.4 μm, abunawo umbala we-oxidation, imihuzuko, noma imifantu
● I-NDT: Ukuhlolwa kwamanje kwe-eddy okungu-100% ngokwe-EN 1971 Class A; ukuhlolwa kwe-ultrasonic kuyatholakala uma kuceliwe
● Ukuhlanzeka kwangaphakathi: Ukuhlanzeka kwangaphakathi kungcono kune-IGC-Test Grade 1, okufanelekela i-hydrogen enomfutho ophezulu, ama-refrigerant, kanye nezinye izinto ezibalulekile
Lawa mashubhu asetshenziswe ngokuthembekile kubunjiniyela basolwandle, amapayipi amanzi olwandle emikhumbi, ama-heat exchanger, izintambo zamandla enuzi, kanye nezinhlelo zokugcina i-hydrogen kanye nezokuthutha ezinomfutho ophezulu. Sisungule ubudlelwano bokuphakelwa kwesikhathi eside nezinkampani eziningi ezihamba phambili embonini futhi sigcina umthamo waminyaka yonke wamathani angu-8,000 wamashubhu e-cupro-nickel asebenza kahle kakhulu. Ukukhiqizwa ngokwezifiso ngokwemidwebo yamakhasimende noma amazinga afana ne-AMS 4574, CuNi30, C71500, BNi-2, njll., kuyatholakala.
