Abstract
The technology of electroslag surfacing and remelting, using a current-conducting mould, as well as the features of mould design, are considered. Experience of upgrading the basic three-section design into a two-section one is described. Ways of development of electroslag surfacing technology with application of current-conducting moulds of different dimensions and cross-sections are shown. 19 Ref., 5 Fig.
Keywords: electroslag surfacing and remelting, current-conducting mould
