ABSTRACT The article based on rebuilding of NO.2 BF in Benxi Iron and Steel Co.According to the equirement of the computer monitoring system in the crafts of BF, a process computer system has been set up and it adopted control computer and S7-400 series PLC produced by SIEMENS company .At the mean time, Monitoring and control parts are configured and programmed to realize the function of monitoring alarming of abnormal signals, logging of history date, guiding of control .After the system put to use, all the things have
proved to be normal work, steadily control and it has practicality for the perfect condition and surrounding for the NO.2 BF achieving its goal in production.
