Flux for Steel Bar Electroslag Pressure Welding

The main factors which have influence on the welding performance and welded joint mechanical performance of steel bar electroslag pressure welding are the flux composition and high-temperature physics performance of the slag. A kind of fused flux has been developed based on the study of these factors.This flux is suitable to steel bar electroslag pressure welding for the class Ⅲ steel bar as the middle Mn and Si type fused flux,and has been extensively applied to building engineering.
