The silicon manganese furnace of automatic batching system is a dynamic Weighing Measuring and Monitoring System, which is based on Batching process, according to formula ratio of cutting. This system has great significance to improve the level of automation of the smelting equipment, improving the working conditions, batching accuracy and batching efficiency, improve the modern enterprise management. First，the paper reviewed the background and development trend of the automatic batching system. On the basis of silicon manganese smelting furnace process batching process，the paper designs the overall program and the basic composition, analysis of the structure, principle and technical parameters of the system equipment. Second, the paper proposed an iterative learning control algorithm about common ingredients for the batching system accuracy, which combined with Iterative control theory and selected the material in advance for the input control on the basis of Batching system to feed the process of mathematical model. The method improves the ingredients ingredients accuracy. Again, according to the actual production of silicon manganese furnace process ingredients, studies its ingredients control software and hardware systems. The system of hardware design uses the IPC (IPC) and PLC combination of the overall control structure. The IPC for the host computer to complete remote monitoring. PLC for the next bit machine to achieve the control of motor action. The weight of the signal acquisition through the weighing instrument. The entire system using RS-485 bus communication. The monitoring software using Visual Basic 6.0 design and development, combining with Access 2003 database, has realized the Silicon manganese furnace of monitoring and weighing real time data acquisition, storage, processing and other functions. Finally, the paper has conducted the system performance test, the results show that the system is running stable and reliable, has high production efficiency, and has control accuracy to meet the requirements.
