Babban bututun ƙarfe-nickel Alloy - Babban juriya ga ruwan teku
Bututun Tagulla Fari (Cupro-Nickel) - Ƙarin Fasaha
Ana ƙera bututun cupro-nickel ɗinmu ta hanyar cikakken tsari na simintin kwance mai inganci, aiki mai sanyi da yawa, da kuma maganin zafi mai kariya don tabbatar da daidaiton haɗin ƙarfe, tsarin hatsi mai kyau, da kuma tsarin microstructure mai yawa.
Babban tsarin aiki: Narkewar injin tsotsa → Simintin da aka yi a kwance (billet mai ci gaba da rabi) → Fitar zafi mai yawa → Birgima/zane mai sanyi mai wucewa da yawa → Annealing mai yawa a ƙarƙashin yanayi mai kariya → Kammalawa na ƙarshe → Gwajin eddy 100% + gwajin ultrasonic (kamar yadda ake buƙata).
Kula da inganci ya wuce ƙa'idodin ƙasa da na ASTM tare da ƙayyadaddun bayanai na cikin gida:
● Haɗaɗɗen sinadarai: Kowane zafi an tabbatar da shi ta hanyar na'urar auna zafin jiki ta hanyar amfani da na'urar auna zafin jiki; bambancin manyan abubuwa (Cu+Ni+Fe+Mn) wanda aka sarrafa a cikin ±0.05%
● Girman hatsi: Ana kiyaye shi akai-akai a 0.015–0.035 mm, babu gaurayen hatsi
● Halayen Inji: Cikakken gwajin ƙarfin tauri, ƙarfin yawan amfanin ƙasa, da tsawaitawa; ma'aunin bambancin (CV) < 3%
● Juriyar girma: OD ±0.015 mm, WT ±0.008 mm, ovality ≤ 0.02 mm
● Kammalawar saman: Fuskar ciki da waje Ra ≤ 0.4 μm, ba tare da launin iskar shaka, ƙagaggu, ko tsagewa ba
● NDT: Gwajin wutar lantarki 100% bisa ga EN 1971 Aji A; gwajin ultrasonic yana samuwa akan buƙata
● Tsaftar ciki: Tsaftar saman ciki ta fi gwajin IGC-Gwajin Mataki na 1 kyau, ta dace da hydrogen mai matsin lamba, firiji, da sauran hanyoyin sadarwa masu mahimmanci.
An yi amfani da waɗannan bututun a cikin injiniyancin ruwa, bututun ruwa na teku, na'urorin musanya zafi, layukan kayan aikin makamashin nukiliya, da tsarin adanawa da jigilar hydrogen mai matsin lamba. Mun kafa alaƙar wadata ta dogon lokaci tare da kamfanoni da yawa masu jagorancin masana'antu kuma muna kula da ƙarfin tan 8,000 na bututun cupro-nickel masu aiki mai kyau a kowace shekara. Ana samun keɓancewa na musamman bisa ga zane-zanen abokin ciniki ko ƙa'idodi kamar AMS 4574, CuNi30, C71500, BNi-2, da sauransu.
