THE CURRENT STATE OF RESOURCE AND ENERGY SAVING IN THE TECHNOLOGY OF PRODUCTION OF CARBON-BASED FILLER OF ELECTRODE PRODUCTS (REVIEW)

Advantages of application of electrocalciners to production of carboniferous fillers of the electrode industry are considered. The analysis of designs of electrocalciners is made, their advantages and disadvantages are given, and also the physical processes happening in them are described. The critical analysis of theoretical and experimental methods of research of physical processes at heat treatment of carboniferous materials in electric furnaces is carried out. It is shown that for development of resource-power effective technical solutions on modernization of the production technology of fillers in electrocalciner it is expedient to combine methods of mathematical modeling with separate pilot studies on the industrial equipment. It is shown that industrial using of resource-power effective technical solutions on modernization of the production technology of fillers in electrocalciner allows to receive the following indicators of efficiency: for anthracite calcinating electrocalciners the resource of work increased from 1 month to 6 months, and specific expenses of the electric power decreased by (50–100) kW·h/t; for graphitizing of oil coke electrocalciners the resource of work increased from 2 days till 1 year, and specific expenses of the electric power decreased more than by 1600 kW·h/t in comparison with classical technology.
