The analysis of efficiency and technological peculiarities
of the ways of the electric power costs reduction at melting
of cast iron and steel in electroarc and induction furnaces
is presented. The most perspective for embedding in
operating houses for conditions of RB is heating of burden
due to natural gas in self-sufficient plants directly in
loading bucket (baskets).

It is shown that using of compound KBM allowed to
reduce the expense of binder, to increase the solidity of
mixture and its plastic properties. Besides, the complex of
additives included into KBM increased the antiburning-on
properties and resistance to scab-forming of agglutinant
sand.

Hardening of agglutinant sands on lignosulphonate
binding agent is the result of two processes: oxidation-reduction in the system lignosulphonate acids — persulfuric
natrium in the early stages of hardening and hydration of
cement in the latter stages.
