FIELD: chemical industry branches, special technical equipment, possibly manufacture of different articles and heat exchanging systems.
SUBSTANCE: process comprises manufacture of preliminarily prepared coke-filler of green or baked petroleum coke by performing steps of disintegrating till fraction 90 micrometers at content of fraction 20 -50 micrometers no less than 60 -65 %, mixing it with coal cake in relation 5.0 - 2.0 respectively; heating up to 1100 -1300°C; cooling, disintegrating till fraction no more than 90 micrometers; using prepared coke-filler for making molding mass of articles; pressing articles, firing them and graphitizating. Steps of mixing disintegrated coke with cake at relation 5.0 - 2.0, heating mixture, cooling it and again disintegrating may be repeated twice. Density of articles 1.78 - 1.80 g/cm3, compression strength 67.0 - 72.0 MPa.
EFFECT: enhanced quality of articles having no surface flaws.
