AWS: SFA 5.5 E9015-B3Ma Electrode a Zitsulo Zosagonja

Ma electrode otsika a haidrojeni 2.25Cr - 1Mo amatulutsa chitsulo, amawonetsa mphamvu zodabwitsa komanso kukana kugwedezeka pa kutentha kokwera mpaka 575 C. Amagwiritsidwa ntchito polumikiza chitsulo cholimba cha 21⁄4 Cr-1 Mo ndi zitsulo za Cr-Mo-V zomwe sizimakhudzidwa ndi haidrojeni pansi pa kukakamizidwa komanso zitsulo zopangidwa ndi chitsulo chofanana ndi zitsulo zosungunuka. Ntchito zambiri zimaphatikizapo kupanga boiler ya nthunzi, kuwotcherera mapaipi a nthunzi ndi superheater, malo opangira magetsi, malo oyeretsera mafuta ndi malo opangira mankhwala.
