Abstract:Kiln is the key equipment in the production of metallurgy， cement and material of fire-fast. It is the statically indeterminate system with over load， large torque and multi-supporting. The rational adjustment of the axes is crucial to the safe operation of rotary kiln. The liner formulas for calculating the supporting force of the supporting wheels fixing on the rotate kiln are derived . The model for optimizing adjustment of kiln axes is established，which object function is the largest supporting force of the supporting wheels. The research for one kiln is achieved in practice. Some useful analysis conclusions are obtained.
Key words: multi-supporting； rotary kiln； adjusting axes； optimizing parameter
