Abstract
The effect of fluoride silicon-free fluxes ANF-6, ANF-25 and ANF-1P, and low-silicon fluxes AN-15 and AN-15M on thermal-physical and physical-chemical processes occurring in liquid-metal electroslag surfacing (LMESS) of dies was assessed. Experimental results allow a conclusion that flux AN-15M is most preferable for LMESS of forming dies. It allows rapid and uniform melting of the surfaces of dies, as well as keeping the composition of the deposited metal almost unchanged, compared to the initial metal of steel 5KhNM chips at up to 50 % desulphurisation degree.
