Implementation of powerful arc steel-smelting furnaces (ASSF) demands the
fundamental improvement of quality for graphite electrodes related with the increase of
admissible density current from 15-20 to 30-32 kА/sm2 possible, by the increase of them
mechanical durability and thermal firmness, and also by the decline of specific electric
resistance [1].
In the structure of charges in relation to a redistribution in ASSF electrodes there is a
15 % general size, which causes the necessity of development for measures, sent to their
decline. At the same time decide a question in relation to the improvement of quality and
perfection of technology of making of electrodes, in particular, productions of high density
electrodes.
