Cov Hlau Sib Txuas Qis
J607CrNiMo
GB/T E6015-G
AWS E9015-G
Kev piav qhia: J607CrNiMo yog cov hlau electrode uas tsis muaj hlau ntau thiab muaj cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive), thiab tuaj yeem vuam tau txhua qhov chaw nrog kev ua haujlwm luv luv. Lub pas nrig vuam muaj qhov tob tob, tsawg dua spatter thiab kev ua haujlwm zoo. Cov hlau tso tawm muaj cov yas zoo, qhov kub tsis tshua muaj zog thiab tsis kam tawg.
Daim Ntawv Thov: Nws yog siv rau kev vuam cov kav dej xa dej hauv qab 350 ° C hauv cov chaw tsim hluav taws xob thiab cov hlau siab ntawm cov qib zog sib xws. Nws muaj kev sib tw zoo nrog cov hlau WB36CN1 (HD15Ni1MnMoNbCu) hauv tsev, thiab kuj tsim nyog rau kev vuam hlau WB3 (15NiCuMoNb5).
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | S | P |
| ≤0.10 | 1.00 ~ 1.60 | ≤0.50 | 0.14 ~ 0.35 | 0.60 ~ 1.20 | 0.15 ~ 0.50 | ≤0.015 | ≤0.015 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % | Tus nqi cuam tshuam (J) -30 ℃ |
| Tau lees paub | 620 ~ 720 | ≥500 | ≥20 | ≥47 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤5.0mL / 100g (mercury lossis roj chromatography txoj kev)
Kev tshuaj xyuas X-ray: Kuv qib
Pom zoo tam sim no:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 100 ~ 140 | 140 ~ 18 | 190 ~ 230 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ ua ntej welding ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, cov roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.
