Investigations of metal carbonization at remelting of chips of four types of steels (high-speed, stamping, hightemperature,
structural) and a high-temperature alloy were performed. It was found that carbonization of electroslag
metal depends both on chemical composition of steel (alloy), and on technological features of melting. The latter
include remelting technique, method and degree of chips cleaning, composition of the used fluxes and temperature
conditions of chips melting in the slag. In most of the cases, carbonization is determined chiefly by presence of LCL
remains in the chips. It is shown that application of current-conducting electrode-mould is recommended for chips
remelting, which allows simplifying the remelting process after achievement of maximum carbonization of the metal.
