Computerized monitoring and control systems are part of the tools commonly in use to improve the stability of the blast furnace operation and to minimize the hot metal cost. The rapidly increasing power of these systems is used to execute growing numbers of specific monitoring and management tasks. More and more sophisticated mathematical models that better describe the complexity of the phenomena involved in the blast furnace process are being run on-line. This evolution, has two very practical consequences: (1) improved software tools are required to ease the use of all the models and functions implemented in the computer systems. In particular, the massive amount of data available has to be converted into a practical diagnostic tool for the operator. Expert systems recently have been shown to provide the basis for a solution to this problem. (2) more and better instrumentation has to be implemented in order to supply the data required by the models. The integrity of these data is a major issue. As the sensors have to operate under extreme hostile environmental conditions, their performances have to be closely monitored. The only practical solution to this problem is a computer monitoring with automatic drift and failure diagnostics (maintenance assistant). Extensive research and development efforts have resulted in instrumentation systems and software tools that are well adapted to the assessment of the measurement quality and are currently in commercial operation on several blast furnaces around the world.
