Molybdenum neChromium Molybdenum Molybdenum Electrode Yekushongedza Simbi Inodzivirira Kupisa

R306Fe                                                     

GB/T E5518-B2

AWS A5.5 E8018-B2

Tsananguro: R306Fe ielectrode yesimbi inodzivirira kupisa ine hupfu hwesimbi uye hydrogen potassium coating yakaderera ine 1% Cr - 0.5% Mo. AC neDC zvese zvinogona kushandiswa, uye zvinogona kusungirirwa munzvimbo dzese nekushanda kwenguva pfupi kwearc. Kudziisa kweweldment uye tembiricha yepakati pezvikamu ndeye 160 ~ 250 °C panguva yekusungirirwa.

Mashandisirwo: Inoshandiswa pakunamira simbi ye1%Cr – 0.5%Mo ine pearlitic inodzivirira kupisa (yakadai se15CrMo), yakaita semapaipi ekupisa pamusoro pebhoyira ane tembiricha yekushanda iri pasi pe550°C, mapaipi emhepo uye midziyo yekumanikidza ine tembiricha yekushanda iri pasi pe520°C, nezvimwewo. Inogona kushandiswa pakunamira simbi ye30CrMnSi.

Kuumbwa kwemakemikari esimbi ye weld (%):

Hunhu hwesimbi ye weld:

Kupararira kwehydrogen musimbi yakachengetwa: ≤6.0mL/100g (nzira yeglycerin)

Kuongororwa kweX-ray: Giredhi I

Inokurudzirwa yemagetsi:

Cherechedza:

1. Electrode inofanira kubikwa kweawa imwe chete pakupisa kwe350℃ isati yashandiswa pakunamira;

2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.
