Ni55 nickel -} Raws Vuam Hlau
🌟 Cov Khoom Muag Txheej Txheem
Ni55 (ernicrmo - 3) yog tus hwm npib npib tsib xee-raws Vuam hlau ua ke rauhigh - corrosion, nruab nrab {1} {{2} high kub (tsawg dua los yog sib npaug) cov ntawv thovCov. Nws zoo nyob rau hauv vuam nickel - Cov ntaub ntawv (piv txwv li no), ua rau nws xaiv cov khoom tseem ceeb hauv:
Tshuaj lom neeg engineering (kua qaub / alkali pipelines, reactors)
Lub zog nuclear (cov hlab ntsha siab, kev sib pauv cua sov)
Marine Engineering (Offshore Platforms, Seaterater Dej)
✨ Cov ntsiab lus tseem ceeb
Zoo tshaj corrosion Kuj: Tsis kam Chloride ion corrosion thiab intergranular corrosion, zoo tagnrho rau ib puag ncig ua phem.
Kub Ceev: Tswj lub zog thiab tawv ntawm qhov kub ntawm qhov kub txog 650 degree.
Txhim khu kev qha weld zoo: Cov ncauj lus impurity tsis loj me me thiab txhaws ua swb, kom muaj kev ua kom zoo sib xws weld kev ua tau zoo.
Kev tiv thaiv kev nyab xeeb (tsis - sib ceg)
Ua ntej cov neeg ua haujlwm thiab ntawm {- chaw ruaj ntseg kom tsis txhob npib tsib xee npe thiab arc txaus ntshai:
Kev Nyab Xeeb Ib puag ncig
Nruab nrog cov neeg kho tshuab fume extractors (siv "muab" tso tawm ua ke "rau hauv cov kab ke; nickel fume concentration tsawg dua los yog sib npaug rau 0.5mg / m³).
Khaws flammables (pleev xim, dej cawv) ntau dua lossis sib npaug li 5m deb; Npaj ABC Qhuav Hmoov Yas Extinguishers.
Kev tiv thaiv tus kheej
HnavN 95+ plua plav daim npog(Tiv thaiv cov npib tsib xee fum) tsis haum) thiab nplaim - retardant vuam sib foob.
Siv vuam kaus mom ntoo nrogntxoov ntxoo nab npawb ntau dua los yog sib npaug rau 10(zam arc qhov muag / tawv nqaij hlawv).
Cuab Yeej Siv Kev Nyab Xeeb
Ua kom ntseeg tau cov cav tov vuam (tsis kam tsawg dua lossis sib npaug rau 4ω); Ntsuam xyuas kom ruaj khov tam sim no (tsis muaj kev hloov pauv / cuam tshuam).
🛠️ Ua Ntej - vuam npaj (lub hauv paus zoo)
Ni55 yog nkag siab impurities {1} Taug kev cov kauj ruam no kom tsis txhob muaj qhov tsis xws luag:
| Npaj khoom | Yuav tsum tau | Lub hom phiaj |
|---|---|---|
| Cov khoom siv hauv paus | 1. Huv zawj + ntau dua lossis sib npaug zos rau 20mm cheeb tsam: tshem tawm cov xeb nrog stainless hlau hlau txhuam → so nrog ethanol / acetone. 2. Preheat tuab daim hlau (ntau dua los yog sib npaug rau 12mm) rau 80-150℃(infrared tus pas ntsuas kub). |
Tiv thaiv porosity los ntawm cov roj / dej noo; Zam kev ua kom txias. |
| Vuam hlau | 1. Tshawb xyuas thaj chaw saum npoo av: Tsis muaj oxidation (Polish me ntsis daj ntseg daj oxidation rau nyiaj {} dawb nrog cov xuab zeb zoo). 2. Store in sealed moisture-proof cabinet (humidity ≤40%); dry at 250℃ for 1h if damp/stored >3 hlis. |
Kom ntseeg tau hlau kev coj dawb huv; Txo cov slag suav nrog. |
| Khoom siv & roj | 1. SivDC Mem Tes Tsig / Mig 焊机(ruaj khov tsis tau). 2. Kev Tiv Thaiv Roj: 99.99% Siab- Kev Purity Agon (O₂ cov ntsiab lus tsawg dua lossis sib npaug rau 0.005%); Siab 0.4-0.6MPA (Regulator yuav tsum tau). |
Tsis txhob weld oxidation; Xyuas kom muaj kev sib tw vuam. |
Core Core Vuam qhov ntsuas (siv)
Kho raws li cov ntaub ntawv tuab tuab -Tsis txhob tshaj tawm tsis tshaj(Tiv thaiv coarse nplej thiab txo cov corrosion tsis kam):
| Vuam txheej txheem | Hlau voos (hli) | Tam sim no (a) | Voltage (v) | Ceev (hli / min) | Argon Flow (L / min) | Daim ntawv thov |
|---|---|---|---|---|---|---|
| TIG (phau ntawv) | 1.6-2.4 | 80-150 | 10-14 | 50-80 | Hauv ntej: 8-12; Tom qab: 6-8 (rau cov hlau tuab) | Thin -} Cov Khoom Siv Walled, Precision JointS (Pipelines) |
| Me nyuam mos | 1.2-1.6 | 180-250 | 18-22 | 100-150 | 15-20 | Cov paib tuab, siab - effecticic vuam |
📌 Vuam Cov Lus Qhia
Luv luv arc tswj: Arc ntev tsawg dua lossis sib npaug ntawm cov kab uas hla (piv txwv li, tsawg dua lossis sib npaug rau 1.6mm xaim) kom muaj kev tiv thaiv roj.
Nws weaving txwv: Weave amplitude tsawg dua los yog sib npaug rau 3 × xaim lub taub uas hla (piv txwv li tsawg dua lossis sib npaug rau 2.0mm xaim) kom tsis txhob ua tiav fusion fusion.
Sib txuam Kub: Khaws tsawg dua lossis sib npaug ntawm 150 Qib (tiag {1} Kev saib xyuas tus pas ntsuas kub infrared) los tiv thaiv weld embrittlement.
Kev Tiv Thaiv Backside: Rau cov xov tooj / nkoj, muab lus argon (6-8L / min) rau weld backside kom tsis txhob oxidation.
🔍 Post -} vuam
KUB CUA TXIAS: Txias rau chav sov lawm (tsis muaj dej txias ncaj qha); insulate high - Kev Txwv Txoj Cai ntawm 200-300 Qib rau 1-2h ua ntej txias.
Saib: Tshem swb rau / txhais nrog stainless hlau hlau txhuam; Pickle blackened oxide nplai nrog 10-15% nitric acid (5-10min) → yaug + qhuav.
Kev Soj Ntsuam Zoo:
Lub ntsej muag: Weld du weld, tsis muaj porosity / slag / kab nrib pleb; Qhov cuab lub zog tsawg dua los yog sib npaug rau 3 hli.
NDT: 100% tus nqi tsim nyog rau U (Ultrasonic) lossis PT (Penetrant) kuaj ntawm qhov tseem ceeb.
