Chubhu yeCopper-Nickel Alloy yePremium - Kudzivirira Mvura yeGungwa Kwakanaka
Chubhu yeCopper Chena (Cupro-Nickel) - Chinowedzera Chehunyanzvi
Machubhu edu e cupro-nickel anogadzirwa kuburikidza nehurongwa hwakazara hwekukanda zvinhu nenzira yakanyatsorongeka, kushanda muchando kakawanda, uye kupisa kwemhepo inodzivirira kuti ive nechokwadi chekuti zvinhu zvakafanana, chimiro chezviyo zvakanatswa, uye chimiro che microstructure chakasimba.
Kuyerera kwemaitiro makuru: Kunyungudutsa kwevacuum induction → Kukanda kwakatambanuka (semi-continuous billet) → Kubuda kwekupisa kwakanyanya → Kutenderedza/kudhirowa kwakatonhora kwakawanda → Kupinza kwepakati pakati pemhepo inodzivirira → Kupedzisa kwekupedzisira → 100% eddy current + kuyedzwa kwe ultrasonic (sezvinodiwa).
Kudzora mhando kunopfuura zvakanyanya mwero wenyika neASTM nezvinodiwa mukati mekambani:
● Kuumbwa kwemakemikari: Kupisa kwega kwega kunosimbiswa nespectrometer inoverenga zvakananga; shanduko huru yezvinhu (Cu+Ni+Fe+Mn) inodzorwa mukati me ±0.05%
● Saizi yezviyo: Inogara ichichengetwa pa 0.015–0.035 mm, hapana zviyo zvakasanganiswa
● Hunhu hwemakanika: Kuedzwa kwakazara kwesimba rekudhonza, simba rekukura, uye kureba; coefficient of variation (CV) < 3%
● Kushivirira kwehukuru: OD ± 0.015 mm, WT ± 0.008 mm, ovality ≤ 0.02 mm
● Kupera kwenzvimbo: Nzvimbo yemukati neyekunze Ra ≤ 0.4 μm, isina ruvara rwekuoxidation, mavanga, kana mitswe
● NDT: Kuyedzwa kwemagetsi eEddy 100% zvichienderana neEN 1971 Class A; kuyedzwa kweultrasonic kunowanikwa kana wakumbira
● Kuchena kwemukati: Kuchena kwemukati kuri nani pane IGC-Test Grade 1, kwakakodzera hydrogen ine simba rakawanda, mafiriji, nezvimwe zvinhu zvakakosha
Machubhu aya anoshandiswa zvakavimbika muinjiniya yegungwa, mapaipi emvura yegungwa, ma "heat exchangers", mitsetse yemagetsi enyukireya, uye masisitimu ekuchengetedza nekutakura ane simba repamusoro. Takagadzira hukama hwenguva refu nemakambani akawanda anotungamira muindasitiri uye tinochengetedza kugona kwegore negore kwematani 8,000 emachubhu e "cupro-nickel" anoshanda zvakanyanya. Kugadzirwa kwakagadzirwa zvinoenderana nedhirowa dzevatengi kana zviyero zvakaita seAMS 4574, CuNi30, C71500, BNi-2, nezvimwewo, kunowanikwa.
