Elektrode-ka Birta Heerkulka Hoose
W707
GB/T E5015-G
AWS A5.5 E7015-G
Sharaxaad: W707 waa elektarood bir ah oo heerkul hoose leh oo leh dahaadh sodium oo hooseeya. Isticmaal DCEP (elektaroodka hadda tooska ah ee togan) waxaana lagu dhejin karaa dhammaan boosaska. Birta la dhigay wali waxay leedahay adkeysi saameyn wanaagsan oo ah -70°C.
Codsiga: Waxaa loo isticmaalaa alxanka birta heerkulka hooseeya sida 2.5Ni.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Sifooyinka farsamada ee birta alxanka:
| Shayga tijaabada ah | Xoogga jiidista Mpa | Xoogga wax soo saarka Mpa | Kordhinta % | Qiimaha saameynta (J) -70℃ |
| Dammaanad qaaday | ≥490 | ≥390 | ≥22 | ≥27 |
Fidinta haydarojiin ee birta la dhigay: ≤6.0mL/100g (habka glycerin) ama ≤10mL/100g (habka mercury ama gaaska chromatography)
Baarista raajada: Darajada I
Hadda lagu taliyay:
| (mm) Dhexroorka usha | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Hadda alxanka | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Ogeysiis:
1. Elektroodka waa in la dubo 1 saac heerkul ah 350℃ ka hor inta aan la isticmaalin alxanka;
2. Isku day inaad isticmaasho tamar yar oo xariiq ah marka aad alxanayso, alxanka lakabka badan leh iyo alxanka badan leh.
