NiCu 400 NiCu Aloyi

NiCu 400 ndi nickel-copper alloy (pafupifupi 67% Ni - 23% Cu) yomwe imagonjetsedwa ndi madzi a m'nyanja ndi nthunzi pa kutentha kwakukulu komanso mchere ndi caustic solutions. Aloyi 400 ndi aloyi yolimba yothetsera vutoli yomwe imangoumitsidwa ndi ntchito yozizira. Nickel alloy iyi imawonetsa mikhalidwe ngati kukana kwa dzimbiri, kuthekera kowotcherera komanso mphamvu zambiri. Kutsika kwa dzimbiri m'madzi othamanga kwambiri a brackish kapena m'madzi am'nyanja ophatikizidwa ndi kukana kwambiri kupsinjika-kusweka kwa dzimbiri m'madzi ambiri opanda mchere, komanso kukana kwake kumitundu yosiyanasiyana ya dzimbiri kumapangitsa kuti azigwiritsa ntchito kwambiri m'madzi am'madzi ndi njira zina zopanda oxidizing chloride. Nickel alloy iyi imalimbana makamaka ndi hydro-chloric ndi hydro-fluoric acid akataya mphamvu. Monga momwe zimayembekezeredwa kuchokera ku mkuwa wake wambiri, alloy 400 imawukiridwa mwachangu ndi nitric acid ndi ammonia machitidwe.

NiCu 400 ili ndi mphamvu zamakina pa kutentha kwa subzero, ingagwiritsidwe ntchito kutentha mpaka 1000 ° F, ndipo malo ake osungunuka ndi 2370-2460 ° F. Komabe, Aloyi 400 ndi otsika mphamvu mu chikhalidwe annealed kotero, zosiyanasiyana kupsya mtima. angagwiritsidwe ntchito kuwonjezera mphamvu.

Makhalidwe a NiCu 400

  • Kugonjetsedwa ndi madzi a m'nyanja ndi nthunzi pa kutentha kwakukulu
  • Kukaniza kwabwino kwa madzi amchere oyenda mwachangu kapena madzi am'nyanja
  • Kukana kwabwino kwambiri pakuwonongeka kwa dzimbiri m'madzi ambiri amchere
  • Makamaka kugonjetsedwa ndi hydro-chloric ndi hydro-fluoric acid pamene iwo ali deaerated
  • Kukana kwabwino kwa mchere wamchere komanso wamchere komanso kukana kwambiri kwa alkalis
  • Kukana kwa kloridi kumapangitsa kupsinjika kwa dzimbiri kusweka
  • Katundu wabwino wamakina kuchokera ku kutentha kwa sub-zero mpaka 1020 ° F
  • Amapereka kukana kwa hydro-chloric ndi sulfuric acid pa kutentha pang'ono ndi kukhazikika, koma nthawi zambiri sizinthu zosankhidwa pazidulo izi.

Alloy iyi yakhala ikugwiritsidwa ntchito ngati zinthu zolimbana ndi dzimbiri, kuyambira koyambirira kwa zaka za m'ma 1900 pomwe idapangidwa pofuna kuyesa kugwiritsa ntchito mkuwa wambiri wa nickel ore. Nickel ndi mkuwa zomwe zili mu ore zinali mu chiŵerengero chapafupi chomwe tsopano chafotokozedwa mwamwambo pa alloy.

NiCu 400 yosamva Corrosion

NiCu Aloyi 400sichingakhudzidwe ndi chloride ion stress corrosion corrosion m'malo momwemo. Nthawi zambiri, kukana kwake kwa dzimbiri ndikwabwino kwambiri pakuchepetsa madera, koma kumakhala koyipa m'malo oxidizing. Sizothandiza mu ma oxidizing acid, monga nitric acid ndi nitrous. Komabe, imagonjetsedwa ndi ma alkalis ambiri, mchere, madzi, zakudya, zinthu zamoyo komanso mlengalenga pa kutentha koyenera komanso kokwera.

Nickel alloy iyi imawukiridwa ndi mipweya yokhala ndi sulfure yopitilira pafupifupi 700 ° F ndipo sulfure yosungunuka imaukira alloy pa kutentha pafupifupi 500 ° F.

NiCu 400 imapereka za kukana kwa dzimbiri komweko monga faifi tambala koma yokhala ndi zovuta zambiri zogwirira ntchito ndi kutentha komanso pamtengo wotsika chifukwa cha kuthekera kwake kopangira makina.

Ntchito za NiCu 400

  • Mainjiniya apanyanja
  • Zida zopangira Chemical ndi hydrocarbon
  • Matanki a petulo ndi madzi opanda mchere
  • Mafuta amtengo wapatali
  • Ma heaters ochotsa mpweya
  • Ma boiler amadyetsa zotenthetsera madzi ndi zina zosinthira kutentha
  • Ma valve, mapampu, shafts, zomangira, ndi zomangira
  • Osinthanitsa kutentha kwa mafakitale
  • Zosungunulira za chlorinated
  • Malo opangira mafuta opangira mafuta

NiCu 400 Fabrication

NiCu Alloy 400 imatha kuwotcherera mosavuta ndi gasi-tungsten arc, arc zitsulo zamagesi kapena njira zotchinga zazitsulo zotchinga pogwiritsa ntchito zitsulo zoyenera zodzaza. Palibe chifukwa positi weld kutentha mankhwala Komabe, bwinobwino kuyeretsa pambuyo kuwotcherera n'kofunika kuti akadakwanitsira dzimbiri kukana, apo ayi pali chiopsezo kuipitsidwa ndi embrittlement.

Kukonzekera kotsirizidwa kungathe kupangidwa kuzinthu zambiri zamakina pamene kulamulira koyenera kwa kuchuluka kwa ntchito yotentha kapena yozizira komanso kusankha mankhwala oyenera otenthetsera kutentha.

Monga ma aloyi ena ambiri a nickel, NiCu 400 nthawi zambiri imakhala yolimba pamakina ndipo imagwira ntchito molimba. Komabe, zotsatira zabwino zitha kupezeka ngati mupanga zisankho zolondola pakugwiritsa ntchito zida ndi makina.
