An approach to fault diagnosis of metallurgical process

摘要

Acquisition of coherent and representative data about the state of proceses remains a majro problem of process control. This paper proposes an approach which ensure coherence in measurements on an operational industrial process. The basic technique employed relies on balance equilibration of resource mass flow. An interesting particularity of the set up is the ease with which it can be adapted to check productivity or detect senosr failures. In the case of sensor failure, it suffices to examine the evaluations before and after balance equilibration. The algorithm was tested by means of computer simulation using data from an industrial metallurgical flow-sheet.
