Abstract
Technological assessment of operation of current-conducting mould of a round cross-section at electroslag surfacing (remelting) was performed. Mould design with forming portion of 200×200 mm square cross-section was proposed. Test melts were conducted in the new mould using consumable electrodes from high-chromium cast iron of 120×120 mm square cross-section. High-quality bimetal blanks from St 3 steel + high-chromium cast iron were produced with layer ratio of 12 and 25, respectively. It is planned to use the blanks as reinforcing elements to protect rapidly-wearing mining equipment parts. Ref. 12, Tabl. 1, Fig. 4.
Keywords: electroslag surfacing; remelting; current-conducting mould; square cross-section; high-chromium cast iron
