Kev piav qhia: J607 yog cov hlau electrode uas muaj zog thiab tsis tshua muaj hlau nrog cov txheej txheem sodium hydrogen tsawg. Siv DCEP (cov electrode tam sim no zoo), thiab tuaj yeem vuam tau txhua qhov chaw.
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) Kev vuamTam sim no | 60 ~ 80 | 70 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 | 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 txoj kev vuam luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog.
