Molybdenum na Chromium Molybdenum Ubushyuhe bwo kurwanya ibyuma byo gusudira Electrode
R407
GB / T E6015-B3
AWS A5.5 E9015-B3
Ibisobanuro: R407 ni pearlitike yubushyuhe bwumuriro wa electrode hamwe na sodium ya hydrogène nkeya irimo 2.5% Cr - 1% Mo. Koresha DCEP (electrode itaziguye) kandi irashobora gusudira mumyanya yose.Gusudira bigomba gushyuha kugeza 200 ~ 300 ° C mbere yo gusudira.
Gusaba: Byakoreshejwe mu gusudira ubushyuhe bwo hejuru nubushyuhe bwo hejuru hamwe nubushyuhe bwakazi buri munsi ya 550 ° C, imashini yimiti ikora, ibikoresho bya peteroli, nibindi.
Ibigize imiti yicyuma (%):
| 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 |
Ibikoresho bya tekinike yicyuma gisudira:
| Ikizamini | Imbaraga Mpa | Tanga imbaraga Mpa | Kurambura % | Agaciro k'ingaruka (J) Ubushuhe busanzwe. |
| Bijejwe | 90590 | 90490 | ≥15 | ≥47 |
| Yageragejwe | 600 ~ 680 | 00500 | 18 ~ 21 |
Diffusion hydrogène yibikoresho byabitswe: ≤4.0mL / 100g (uburyo bwa glycerine)
Igenzura rya X-ray: I amanota
Icyifuzo kigezweho:
| Diameter （Mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Kuzenguruka A） | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Icyitonderwa:
1. Electrode igomba gutekwa kumasaha 1 kuri 350 ℃ mbere yo gusudira;
2. Ni ngombwa guhanagura ingese, igipimo cyamavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira.
