I-Molybdenum ne-Chromium Molybdenum Heat Resistant SteelUkushiselaI-Electrode
R306
I-GB/T E5516-B2
I-AWS A5.5 E8016-B2
Incazelo: I-R306 iyi-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic ene-low-hydrogen potassium coating equkethe u-1% Cr - 0.5% Mo. Kokubili i-AC ne-DC ingasetshenziswa, futhi ingashiswa kuzo zonke izikhundla.I-weldment kufanele ishiswe ngaphambili ibe ngu-160 ~ 250 ° C ngaphambi kokushisela.
Isicelo: Isetshenziselwa ukushisela i-Cr 1% - Mo 0.5% insimbi engazweli ekushiseni izinga lokushisa layo lokusebenza lingaphansi kuka-520 ℃, njengamapayipi obhayela, imikhumbi yokucindezela, izishisi nemishini yokuhluza i-petroleum, njll.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
C | Mn | Si | Cr | Mo | S | P |
0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.60 | 0.80 ~ 1.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
Izici zemishini ye-weld metal:
Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % | Inani lomthelela (J) ITemp Ejwayelekile. |
Kuqinisekisiwe | ≥540 | ≥440 | ≥17 | ≥47 |
Okwamanje okunconyiwe:
Ububanzi benduku (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
I-Welding Yamanje (A) | 60 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-350 ℃ ngaphambi kokusebenza kokushisela;
2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
