Cov raj hlau tooj liab-nickel zoo tshaj plaws - Kev tiv taus dej hiav txwv zoo heev

Lub raj tooj liab dawb (Cupro-Nickel) - Kev Ntxiv Txuj Ci

Peb cov raj cupro-nickel yog tsim los ntawm cov txheej txheem tswj hwm tag nrho ntawm kev ua haujlwm siab-precision kab rov tav txuas ntxiv, ntau-pass txias ua haujlwm, thiab kev kho cua sov tiv thaiv kom ntseeg tau tias muaj cov khoom sib xyaw ua ke, cov qauv noob zoo, thiab cov qauv me me.

Cov txheej txheem tseem ceeb: Lub tshuab nqus tsev yaj → Kab rov tav txuas ntxiv casting (semi-continuous billet) → High-ratio kub extrusion → Multi-pass txias dov / kos duab → Ntau intermediate annealing nyob rau hauv huab cua tiv thaiv → Qhov kawg tiav → 100% eddy tam sim no + ultrasonic kuaj (raws li xav tau).

Kev tswj xyuas zoo nruj dua li cov qauv hauv tebchaws thiab ASTM nrog cov lus qhia hauv tsev:

● Cov tshuaj lom neeg muaj pes tsawg leeg: Txhua qhov kub tau txheeb xyuas los ntawm lub tshuab ntsuas kub ncaj qha; cov ntsiab lus tseem ceeb (Cu + Ni + Fe + Mn) kev hloov pauv tswj tau hauv ± 0.05%
● Qhov loj ntawm cov noob: Khaws cia tas li ntawm 0.015–0.035 hli, tsis muaj cov noob sib xyaw
● Cov khoom siv kho tshuab: Kev sim tag nrho ntawm lub zog tensile, lub zog yield, thiab elongation; coefficient of variation (CV) < 3%
● Kev kam rau siab ntawm qhov ntev: OD ±0.015 hli, WT ±0.008 hli, qhov ovality ≤ 0.02 hli
● Qhov chaw tiav: Sab hauv thiab sab nraud Ra ≤ 0.4 μm, tsis muaj xim oxidation, khawb, lossis tawg
● NDT: 100% eddy tam sim no kev sim ib qho EN 1971 Chav A; kev sim ultrasonic muaj thaum thov
● Kev huv sab hauv: Kev huv ntawm sab hauv zoo dua li IGC-Test Qib 1, tsim nyog rau cov hydrogen siab, cov tub yees, thiab lwm yam xov xwm tseem ceeb

Cov raj no tau siv tau zoo hauv kev tsim kho hauv dej hiav txwv, cov kav dej hauv dej hiav txwv, cov khoom sib pauv cua sov, cov kab hluav taws xob nuclear, thiab cov tshuab cia hydrogen siab thiab kev thauj mus los. Peb tau tsim kev sib raug zoo ntev nrog ntau lub tuam txhab ua lag luam thiab tswj hwm lub peev xwm txhua xyoo ntawm 8,000 tons ntawm cov raj cupro-nickel ua tau zoo. Kev tsim khoom raws li cov duab kos lossis cov qauv xws li AMS 4574, CuNi30, C71500, BNi-2, thiab lwm yam, muaj.
