Abstract

Different variants of control of the state of steelmaking equipment are presented. Vibration control is of course the most known method, but alternative techniques are existing. E.g. impact impulse method can provide diagnostics of slowly rotating bearings which is impossible via vibration observation. The structure of diagnostics includes evaluation of the specialist using observation, touching and hearing. The presented method is realized inside the Acoustic Expert system with good reproducibility and quantitative parameters. Different observation solutions for monitoring of the state of equipment are used at the works and present a kind of challenge for the technical maintenance personnel. This paper is devoted to two of these challenges, but usually there are a lot of them. To make the daily operation at the technical maintenance team more easy, all information about the state of steelmaking equipment from the whole works is verified, and finally the plan of measures for technical maintenance is concluded.
