Sažetak
The results of the study of the electrical resistance and the temperature of the beginning of softening of high-ash coals of three working seams of the Saryadyr deposit and mixtures of charge materials are presented. The high electrical resistance of the charge in the ore smelting furnace provides a low proportion of charge conductivity and, thereby, contributes to the release of the bulk of the energy in the reaction zone of the furnace, where the metal is formed. The research results showed that the magnitude of the electrical resistance of the charge during non-isothermal heating to high temperatures largely depends on the chemical and mineralogical composition of the charge, as well as on the processes of phase transformations in the sample.
