The inner temperature characteristics and the total control requirements of the rich-or pure-oxygen ceramic roller kiln were firstly analyzed. And thus, a scheme of kiln temperature controller based on TMS320LF2407 DSP processor was proposed. Then the hardware circuit of controller was designed. The experimental results show that the controller can meet the technical requirements of the rich-or pure-oxygen ceramic roller kiln, improve the control accuracy and response speed of the kiln temperature control, and increase the reliability of the kiln control system. In addition, the controller is characterized by high integrity and low cost.
