Study on the Dephosphorization in Basic Electrode Welding

Abstract:

The process of dephosphorization for basic electrode and distribution of phosphours between slag and deposited metal(Lp) in manual metal arc welding has been researched by means of experimental and theortical analyses. The results indicate that P content in deposited metal decreased with the increase of coating basicity of the electrode and FeO content in slag. The distributive coefficient of phosphorus Lp increased with the increase of coating basicity of the electrode and FeO content in slag. Although dephosphprylation in deposited metal was a limit finally, it was satisfactory under suitable selsction of the value of FeO in slag and coating basicity of the electrode according to the experimental results.
