APPLICATIONS:
Ndioyenera kuwotcherera chitsulo champhamvu kwambiri cha imvi ndi chitsulo chosungunuka, monga silinda, chipika cha injini, bokosi la gear, ndi zina.
MAKASI:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
JIS Z3252 DFCNiFe
MAKHALIDWE:
AWS ENiFe-CI (Z408) ndi elekitirodi yachitsulo yopangidwa ndi nickel iron alloy pachimake komanso kuchepetsa mwamphamvu zokutira kwa graphite.Itha kugwiritsidwa ntchito mu AC ndi DC zolinga ziwiri, ili ndi arc yokhazikika, ndipo ndiyosavuta kugwiritsa ntchito.Elekitirodi ili ndi mawonekedwe amphamvu kwambiri, pulasitiki yabwino, kutsika kwa mzere wocheperako ndi zina zotero.Kukaniza kwa chitsulo cha imvi ndikofanana ndi kwa Z308, pomwe kukana kwa chitsulo cha nodular kupitilira ENi-CI (Z308).Kwa chitsulo choponyedwa chokhala ndi phosphorous yapamwamba (0.2% P), chimakhalanso ndi zotsatira zabwino ndipo kudulidwa kwake kumakhala kochepa kuposa Z308 ndi Z508 pang'ono.Z408 imagwiritsidwa ntchito powotcherera chitsulo chotuwa ndi chitsulo choponyera nodular m'malo
CHENJEZO:
Musanawotchere, maelekitirodi ayenera kuphikidwa kwa ola limodzi ndi kutentha kwa 150±10 ℃ musanagwiritse ntchito.
Pamene kuwotcherera, ndi koyenera kutenga weld yopapatiza ndipo kutalika kulikonse kuyenera kusapitilila 50mm.Menyani malo owotchera mopepuka ndi nyundo mutangowotchera kuti muchepetse kupsinjika ndikupewa ming'alu.
Kuyika kwa kutentha kochepa kumalimbikitsidwa.
KAPANGIZO WA CHEMICAL WA CHITSULU CHOPEREKA(CHIGWIRITSO CHA MASANA):%
| Zinthu | C | Si | Mn | S | Fe | Ni | Cu | Unyinji wa zinthu zina |
| Mtengo wokhazikika | 0.35-0.55 | ≤0.75 | ≤ 2.3 | ≤0.025 | 3.0- 6.0 | 60- 70 | 25- 35 | ≤ 1.0 |
KULIMBITSA NTCHITO TSOPANO:(AC,DC+)
| Electrode diameter (mm) | 3.2 | 4.0 | 5.0 |
| Utali (mm) | 350 | 350 | 350 |
| Welding panopa (A) | 90-110 | 120-150 | 160-190 |
Makhalidwe Ogwiritsa Ntchito:
Arc yokhazikika kwambiri.
Wabwino kuchotsa slag.
Kulowa ndi osaya.
Kutentha kwabwino komanso kukana dzimbiri.
Kulimbana bwino kwa crack.
