Application of the most promising surfacing material — discrete filler makes a significant difference in the processes of surfacing with current-supplying mould. Influence of surfacing current and electric power applied to the slag pool, on its angular velocity of rotation at application of three commercial flux grades was studied. It is found that NAF-29 flux allows producing a sufficiently large rotating effect both during the period of slag pool formation, and during surfacing. ANF-32 flux is less effective during the period of sag pool formation. AN-26 flux provides active rotation of the slag pool during surfacing, but this requires applying higher electric power to the pool. Angular velocity of slag pool rotation is affected both by electric power applied to the slag pool, and surfacing current, but the latter has a determinant influence. 16 Ref., 1 Tabl., 2 Fig.
