Abstract：Adopting single slag fast dephosphorization for tapping[P]≤0.010%and 0.035%-0.05%aim carbon content in converter operation, controlling refining slag system and the oxygen content in LF, using full protection pouring, stopper automatic control and mould electromagnetic stirring in casting and control rolling and control cooling in rolling, Guangfu Group developed and produced ER50-6 welding wire steel. The Product inspection showed that the chemical composition is stable and uniform. The oxygen content in the steel is (15-35)×10-6. Casting billet microstructure compacts;The central porosity is≤1.0 grade. The tensile strength of the hot rolled wire rod is 500-550 MPa and the elongation is≥25%.
