Elektrode-ka Alxanka Nikkel iyo Nikkel
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Sharaxaad: Ni307-2 waa elektroodh ku salaysan nikkel oo leh dahaadh sodium oo hooseeya. Isticmaal DCEP (elektroodh toos ah oo hadda jira oo togan). Maadaama alxanku uu ka kooban yahay xaddi cayiman oo molybdenum, niobium iyo walxo kale oo isku-dhafan, birta la dhigay waxay leedahay iska caabin wanaagsan oo dildilaac ah.
Codsiga: Waxaa loo isticmaalaa alxanka birta nikkel-chromium-ka (sida UNS N08800, UNS N06600), gaar ahaan ku habboon alxanka biraha kala duwan, alxanka lakabka kala-guurka iyo alxanka dusha sare, waxaana sidoo kale loo isticmaali karaa marka heerkulka shaqadu yahay 980 ° C, laakiin wuxuu iska caabin karaa oksaydhka marka heerkulku ka sarreeyo 820 ° C. Galmada iyo xoojinta oo yaraatay.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Kale |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Sifooyinka farsamada ee birta alxanka:
| Shayga tijaabada ah | Xoogga jiidista Mpa | Xoogga wax soo saarka Mpa | Kordhinta % |
| Dammaanad qaaday | ≥550 | ≥360 | ≥27 |
Hadda lagu taliyay:
| Dhexroorka usha (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Hadda alxanka (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Ogeysiis:
1. Elektroodka waa in la dubo 1 saac qiyaastii 300℃ ka hor inta aan la isticmaalin alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda ku jirta qaybaha alxanka ka hor inta aan la alxanka. Isku day inaad isticmaasho qaanso gaaban si aad u alxanto.
