Abstract
The influence of the slag bath rotation speed on refining of the structure of metal deposited with PR-10R6M5 powder was evaluated by example of electroslag surfacing in Ø 180 mm current-carrying mould. It is established that rotation of the slag bath, provided by the design of the current-carrying mould, contributes to the refinement of the deposited steel grain by 1.3...1.5 times. It is shown that the MIPAR software can be used to objectively assess the changes that occur in the structure of the deposited metal during structural transformations during its crystallization. 13 Ref., 2 Fig.
Keywords: electroslag surfacing, high-speed steel, current-carrying mould, slag bath rotation, structure of deposited metal, grain size
