The analysis of the existing researches of carbonaceous raw materials heat treatment process has been executed. It has been determined that research of the influence of such technological parameters as supplied current intensity and the loading/unloading rate of the material on electric calciner working space temperature fields remains beyond the attention of the researchers. Therefore the electric calciner working space temperature fields change, depending on the supplied current and the loading/unloading rate of the material has been investigated. In this research, the entire electric calciner working space was conventionally divided into three zones. In the first zone, the loaded material is heated due to the heat exchange with the hotter layers of the material and the parts of the electric calciner. The density of the current passing through the material in this zone is negligible, therefore the heating due to joule heat is quite little. The second zone is the most important, because it is right here that graphitization of carbon material takes place due to heating up to 2200°С with joule heat emitted when the current passes through the material. The temperature field in this zone determines the qualitative parameters of the processed material, therefore, this zone was considered in research. In order to ensure the required quality of material, it is necessary that in this zone the temperature of 2200°C should be established, while a significant problem is to reduce the temperature gradient in this zone. Therefore, this research considered both temperature fields of this zone and the minimum and maximum temperatures. In the third zone cooling of the treated material and the lower electrode occurs due to the water flow in the support volume. As a result of the research carried out with the help of the developed model, the positive effect of increasing the current and the negative influence of increasing the loading rate on average temperature in the second zone of the apparatus have been revealed. At the same time, these technological parameters increase negatively affects the temperature difference in the second zone, causing gradient increase, which negatively affects the quality of the processed material
