STUDY OF HEAT AND MASS TRANSFER DURING FIRING OF HEAT INSULATION OBJECTS BASED ON BURNT ROCKS AND BEIDELLITE CLAY

摘要

Heat and mass transfer is studied during firing of ceramic heat insulation objects making it possible to monitor firing taking account of a change in the effective thermal properties of an object, manufactured using burnt rocks, in the temperature range of physicochemical transformations, and also to determine rational firing regimes. It is revealed that the least value for the coefficient of effective thermal conductivity for the material corresponds to a temperature range within which the intensity of physicochemical processes is more significant.
