Development of disk connections between billets in columns and energy-efficient graphitizing regulations for electrodes in direct-heating furnaces

The requirements for electric contact joints between workpieces in the core columns of Kastner furnaces are formulated. The choice of a material - graphite foam - for making electric contact gaskets is justified. Rational form and thickness of electric contact pads have been determined, the glue for their fixation between electrode blanks has been selected. A mold for forming electrocontact pads has been developed and prototypes of pads of different shapes, thickness and density have been made in order to check their suitability for forming Kastner furnace core under industrial conditions.

The development of energy-efficient designs direct heating the Castner furnace for graphitization electrode products

Energy-saving constructions and regulations of the Castner furnaces operation were developed for graphitization of large-sized electrode workbenches, which have no other analogue in Ukraine and reach energy expenses decrease by 20–25 %. Thermal and electrical furnace state was experimentally investigated during graphitization of electrode workbenches with different expansion blocks. It was found out that gasification process of carbon material by water vapor occurs in operation area during graphitization process in the Castner furnace.

The development of computational fluid dynamics and heat transfer software for supersonic flow interactions

Gas-dynamic and heat transfer mathematical model of supersonic flow over flying vehicles is developed. The model is taken into account with medium compressibility and dissipative effects leading to an increase of heating rate. Proposed model is based on physical interaction of shock wave and boundary layer. Three dimensional numerical models of flying vehicles in gas-dynamic states are developed in order to investigate different configurations concerning such systems as case - sharp swept fin, case - perpendicular cylinder, case - gas jet, case - sharp unswept fin.

The development of resources and energy saving measures in the electrode production

The updated technology of electrode production has been developed as a sum of new and modernized technological schedules and industry equipment constructions. The actuality of the design of resources and energy saving measures in the electrode production was stated. The experimental temperature dependence of carbon materials physical properties was proved. Technical solutions of current equipment modernization were found out.
