Nikkel iyo nikkel Alloy alxanka Electrode
Ni307-7
GB/T ENi6152
AWS A5.11 ENiCrFe-7
Sharaxaad: Ni307-7 waa koronto-ku-saleysan nikkel oo leh daahan sodium-hydrogen hooseeya.Isticmaal DCEP (electrode toos ah haddatogan).Waxay leedahay waxqabadka alxanka oo aad u fiican oo leh gubasho qallafsan oo deggen, spatter yar, si fudud u saarista slag,iyo alxanka quruxda badan.Birta la shubay waxay leedahay sifooyin farsamo oo deggan iyo iska caabin daxalka oo wanaagsanHeerkulka sare ee oksaydhaynta iyo jawiga baaruudku ka kooban yahay.
Codsiga: Loo isticmaalo injineernimada nukliyeerka, sulfuric acid, nitric acid iyo hydrogen fluorine qalabka wax soo saarka, sida nikkel 690 aluminium, ASTM B166, B167, b168, iwm. -lakabyada u adkaysta birta.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Fe | Si | Ni | Cr |
| ≤0.05 | ≤5.0 | 7.0 ~ 12.0 | ≤0.8 | ≥50.0 | 28.0 ~ 31.5 |
| Cu | Mo | Nb | S | P | Mid kale |
| ≤0.5 | ≤0.5 | 1.0 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.5 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % |
| La damaanad qaaday | ≥550 | ≥360 | ≥27 |
Hadda lagu taliyay:
| Dhexroor usheeda (mm) | 2.5 | 3.2 | 4.0 |
| Hadda alxanka (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
Ogaysiis:
1. Elektroodka waa in lagu dubaa 1 saac ku dhawaad 300℃ ka hor alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.Isku day inaad isticmaasho qaanso gaaban si aad u alxanto.
