The results of application of various manufacturing and restoration industrial electroslag surfacing technologies using an electromagnetic surfacing device – a current-carrying mould – are presented. The positive effect of electromagnetic influence on the formation of a fine-grained structure of wear-resistant cast irons and steels has been established. The methods of regulating the slag bath rotation by changing the design of the mould or using additional sources of magnetization for surfacing large rolls of wide strip hot rolling mills are shown. 17 Ref., 10 Fig.
Keywords: electroslag surfacing, high-speed steel, high-chromium cast iron, current-carrying mould, slag bath rotation, deposited metal structure, ESS of horizontal surfaces, vertical circumferential ESS
