AWS E8018-B2 Chromium Molybdenum Wosatentha ndi Chitsulo Chosagwira Kutentha ndi Electrode R306Fe Stick Electrodes Wowotcherera Zogwiritsidwa Ntchito

Molybdenum ndi Chromium Molybdenum Wowotcherera Chitsulo Chosatentha ndi Kutentha

R306Fe                                                     

GB/T E5518-B2

AWS A5.5 E8018-B2

Kufotokozera: R306Fe ndi electrode yachitsulo yolimba yolimbana ndi kutentha yokhala ndi ufa wachitsulo ndi chofunda chochepa cha hydrogen potaziyamu chokhala ndi 1% Cr - 0.5% Mo. AC ndi DC zonse zingagwiritsidwe ntchito, ndipo zimatha kulumikizidwa m'malo onse ndi ntchito yochepa ya arc. Kutentha koyambirira kwa weldment ndi kutentha kwa interlayer ndi 160 ~ 250 °C panthawi yolumikizira.

Kugwiritsa Ntchito: Kugwiritsidwa ntchito powotcherera zitsulo za 1%Cr – 0.5%Mo zomwe sizimatentha (monga 15CrMo), monga mapaipi otenthetsera pamwamba pa boiler okhala ndi kutentha kogwira ntchito kochepera 550°C, mapaipi a nthunzi ndi zotengera zopanikizika zokhala ndi kutentha kogwira ntchito kochepera 520°C, ndi zina zotero. Zingagwiritsidwe ntchito powotcherera zitsulo za 30CrMnSi.

Kapangidwe ka mankhwala a chitsulo chosungunula (%):

Kapangidwe ka makina a chitsulo chosungunula:

Kuchuluka kwa haidrojeni m'chitsulo chosungidwa: ≤6.0mL/100g (njira ya glycerin)

Kuwunika kwa X-ray: Giredi I

Mphamvu yovomerezeka:

Zindikirani:

1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha kwa pafupifupi 350℃ isanayambe kuwotcherera;

2. Ndikofunikira kuyeretsa dzimbiri, mafuta oyeretsera, madzi, ndi zinyalala pa zipangizo zowotcherera musanawotchetse.
