Molybdenum iyo Chromium Molybdenum Kuleyl u adkaysta Birta alxanka Electrode
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Sharaxaad: R407 waa koronto bir ah oo kulaylka u adkeysata leh oo leh daahan sodium-hydrogen hooseeya oo ka kooban 2.5% Cr - 1% Mo. Isticmaal DCEP (electrode toos ah oo qumman) oo lagu alxan karo dhammaan boosaska.Alxanka waa in horay loo sii kululeeyaa ilaa 200 ~ 300 ° C alxanka ka hor.
Codsiga: Waxaa loo isticmaalaa alxanka tuubooyinka heerkulka sare iyo cadaadiska sare leh heerkulka shaqada ee ka hooseeya 550 ° C, mashiinka kiimikada synthetic, qalabka dildilaaca batroolka, iwm.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % | Qiimaha saamaynta (J) Heerkulka caadiga ah |
| La damaanad qaaday | ≥590 | ≥490 | ≥15 | ≥47 |
| La tijaabiyay | 600 ~ 680 | ≥500 | 18 ~ 21 |
Mawduuca hydrogen firdhinta ee birta kaydsan: ≤4.0mL/100g (habka glycerin)
Kormeerka raajada: Waxaan darajo
Hadda lagu taliyay:
| Dhexroor usheeda (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Alxanka Hadda (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Ogaysiis:
1. electrode waa in lagu dubaa 1 saac at 350 ℃ ka hor hawlgalka alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
