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.
