Molybdenum na Chromium Molybdenum Ubushyuhe bwo kurwanya ibyuma byo gusudira Electrode
R306Fe
GB / T E5518-B2
AWS A5.5 E8018-B2
Ibisobanuro: R306Fe ni electrode irwanya ubushyuhe bwa pearlitike ifite ifu yicyuma hamwe na potasiyumu yo mu bwoko bwa hydrogène yo hasi irimo 1% Cr - 0.5% Mo. Byombi AC na DC birashobora gukoreshwa, kandi birashobora gusudira mumyanya yose hamwe nibikorwa bya arc bigufi.Ubushyuhe bwo gusudira hamwe nubushyuhe bwa interlayer ni 160 ~ 250 ° C mugihe cyo gusudira.
Gusaba: Byakoreshejwe mu gusudira 1% Cr - 0.5% Mo pearlitis ibyuma birwanya ubushyuhe (nka 15CrMo), nkibikoresho byo gushyushya ibyuka bifite ubushyuhe bwakazi buri munsi ya 550 ° C, imiyoboro yamazi hamwe nubwato bwumuvuduko ufite ubushyuhe buri munsi ya 520 ° C. , nibindi birashobora gukoreshwa mugusudira 30CrMnSi ibyuma.
Ibigize imiti yicyuma (%):
C | Mn | Si | Cr | Mo | S | P |
0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 1.00 ~ 1.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
Ibikoresho bya tekinike yicyuma gisudira:
Ikizamini | Imbaraga Mpa | Tanga imbaraga Mpa | Kurambura % | Agaciro k'ingaruka (J) Ubushuhe busanzwe. |
Bijejwe | 40540 | 40440 | ≥47 | ≥27 |
Yageragejwe | 550 ~ 640 | 50450 | 20 ~ 28 | 105 ~ 150 |
Diffusion hydrogène yibikoresho byabitswe: ≤6.0mL / 100g (uburyo bwa glycerine)
Igenzura rya X-ray: I amanota
Icyifuzo kigezweho:
Diameter (Mm) | 3.2 | 4.0 | 5.0 |
Kuzenguruka A) | 100 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Icyitonderwa:
1. Electrode igomba gutekwa kumasaha 1 hafi 350 ℃ mbere yo gusudira;
2. Ni ngombwa guhanagura ingese, igipimo cyamavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira.
