High Carbon steels SAW vuam hlau F7A0-EM12 thiab vuam flux vuam cov ntaub ntawv
Siv rau shipbuilding, steel qauv, hnyav machinery thiab lwm yam khoom siv vuam, kuj siv tau rau high-speed vuam
Vuam ceev ≤1000mm / min)
Dab tsi yog characieristics?
●Submerged arc vuam hlau rau 480MPa qib siab zog hlau; Nrog GXL-301 flux vuam, vuam arc combustion yog ruaj khov, yooj yim tshem tawm slag, zoo nkauj vuam dhau txoj kev.
●Cov hlau welded muaj cov khoom siv zoo thiab qhov siab dhau ntawm X-ray.
