... Abstract. The work is aimed at expanding the application and improving numerical experiment based studies of heat treatment processes extensively applied to non-inert materials in rotary kilns. The purpose of the research is to develop new computer oriented algorithms for calculation of convective heat transfer coefficients used to build heat balance equations applied in zone method simulation of heat transfer processes that take place in kilns. The article describes a case of carbon materials calcinated in parallel-flow and counterflow modes and demonstrates an algorithm building procedure for the convective heat transfer coefficients identified first for volumetric gas zones and after that for surface zones. Unlike the algorithms used before in heat treatment simulation of inert materials these new algorithms account for the convective flows resulting from stripping of volatiles from the treated material and the interaction of the material and the volatiles with the gas flow. The algorithms designed for volumetric zones are identical for the parallel-flow and counterflow modes. As for the surface zones some of the equations included in the algorithms are different. The article presents numerical experiment data for a petroleum coke calcination process which were obtained with the help of the developed algorithms and a computer software. Correctness of the improved mathematical model was verified by means of parametric identification based on actual kiln data. Deviation of the calculated parameters from the actual process parameters is less than 5%. The research was carried out by the Department of Theory and Automation of Metallurgical Processes and Furnaces of the North Caucasian Institute of Mining and Metallurgy in 2014 and 2015. The mathematical model and the software are effectively applied in numerical experiment based research. The advanced comprehensive mathematical model designed for heat treatment processes of a rotary kiln and the software developed for the above model can be used to study a broad range of heat treatment processes applied to both inert and noninert materials in rotary kilns. Keywords: Carbon materials calcination rotary kiln mathematical model algorithm convective heat transfer identification numerical experiment. References 1. Arutyunov V.A. Bukhmirov V.V.
