According to actual condition, a model of wall thickness of rotary kiln is established. The constant coefficients in the model, including thermal conductivity, heat transfer coefficient, Fourier coefficient and contact resistance, are closely calculated. A formula of contact resistance is draw from a great deal of data of surface and inner temperature of rotary kiln. The wall thickness of rotary kiln is simulated by MATLAB. The simulation result is transmitted from MATLAB to DELPHI through a group of interface functions compiled by VC++. The basic graphs-circle and line are analyzed by the means of the technique of Visualization in Scientific Computing and the Bresenham arithmetic, and are realized the visualization of the wall thickness. The contents of communication between master computer and slaver computer are designed and the error control technique, the idea of multi-thread and the embedded assembly language are applied to realize the temperature data transmission and graph transmission, which largely improved the speed of transmission and the reliability and stability of system.

The movement can be divided into two regions, one is the active surface region, the other is the solid region, and it goes under the way of rolling and falling. The heat transfer process in rotary kiln goes with extremely complex physical and chemistry process. Considering the revolving of the kiln body itself and the special movement way of the materials, as well as the influence of the material reaction dynamic parameters, we have established the unidimensional axial heat transfer model for rotary kiln. Then according to the tentative data which has been published, we have testified that the unidimensional axial heat transfer model could reflect the
