Abstract
Applicability of fluxes of different grades at electroslag surfacing of end faces by discrete filler material in a current-supplying mould was studied. It is found that selection of fluxes proceeding just from their physical properties (viscosity and electrical conductivity) does not guarantee the conditions required for conducting the electroslag process. Optimum position of the billet end face to be surfaced in the mould working cavity is very important for normal operation of the mould and performance of sound surfacing with good formation of the deposited metal. In view of the above-said, ANF-29, ANF-32, ANF-26 fluxes can be used for electroslag surfacing with discrete material. 20 Ref., 2 Tables, 4 Figures.
Keywords: electroslag surfacing of end faces, flux, discrete filler, current-supplying mould, current, voltage, process stability
