Application of the most promising surfacing material — discrete filler — makes a significant difference in the processes of surfacing with current-supplying mould. Influence of electric parameters of surfacing on angular speed of slag pool rotation at application of three commercial flux grades was studied. It is found that ANF-29 flux allows producing a sufficiently large rotational effect both during the period of slag pool formation, and during surfacing. ANF-32 flux is less effective during the period of slag 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 speed 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 Table, 2 Figures.
