Design And Implementation Of Temperature Control System For TianGang MAERZ Kiln

The use of lime has a long history. From the historical records on more than4,000years ago in China’s ancient will produce lime and using lime. In the modern large-scale production, active lime is the main raw material steel enterprises, converter steelmaking using active lime is a basic technical policies. In addition, Activity lime also applied to molten steel refined and iron ore powder sintering process., also has achieved good results. In short, lime production activity in the steel business occupies an important position.Taking Tianjin steel group Co.,LTD’s MAREZ Kiln as the background. The article introduces the technical process,process characteristics and main technical indices. On access control of temperature, the characteristics of the nonlinear, hysteresis. At the gas and combustion air of the traditional PID control policy has been adjusted, join the Smith algorithm and fuzzy control. The system has good performance of more dynamic and resistance disturbance performance and the ability to adapt to change a parameter object. According to the existing problem of stable temperature channels, for combustion air control system was reformed. In the existing combustion air duct mounted on detecting device, and passes the date along to participate in the control of the PLC. Change the existing frequency converter from CUVC terminals control to PROFBUS-DP control. By the two major transformations, help the combustion air of the accuracy and precision control testing. To help the combustion air and the gas control of the more precise, path to stability of the temperature object. Simulation results show that, the Temperature control system which based on fuzzy and Smith Predictor has the better dynamic performance than the traditional control strategy.
