Cov Hlau Sib Txuas Qis
J606
GB/T E6016-D1
AWS E9016-D1
Kev piav qhia: J606 yog cov hlau electrode uas muaj zog tsawg nrog cov txheej txheem potassium hydrogen tsawg. Nws tuaj yeem siv rau kev vuam txhua qhov chaw nrog AC thiab DC. Kev ruaj khov ntawm AC vuam tsis zoo li DC vuam.
Daim Ntawv Thov: Siv rau kev vuam cov hlau carbon nruab nrab thiab cov hlau tsis tshua muaj zog uas muaj zog sib xws, xws li Q420, thiab lwm yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Mo | S | P |
| ≤0.12 | 1.25 ~ 1.75 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.035 |
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 | ≥590 | ≥490 | ≥15 | ≥27 |
| Tau kuaj xyuas | 620 ~ 680 | ≥500 | 20 ~ 28 | ≥27 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤4.0mL / 100g (txuj ci glycerin)
Kev tshuaj xyuas X-ray: Kuv qib
Pom zoo tam sim no:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 | 5.8 |
| (Ib) Vuam Tam Sim No | 40 ~ 70 | 70 ~ 90 | 90 ~ 120 | 140 ~ 180 | 180 ~ 220 | 210 ~ 260 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj nplai, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam;
3. Siv lub voj voog luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog;
4. Thaum qhov chaw vuam tuab, nws yuav tsum tau preheated rau saum 150 ° C thiab txias maj mam tom qab vuam.
