"For controlling individual heat phases in Electric Arc Furnaces, a model calculation was developed that allows the EAF operator to predict technological as well as cost impacts of different potential control interventions on heat results under given heat"@en . . . . . . . "The level of control of a melting process in steel making units is judged on the basis of numerous parameters out of which the quality of outlet product, the power and time consumption and/or the actual cost are of utmost significance. These parameters are influenced by both the properties and/or structure of the inlet substances entering the technological process and by the magnitudes as well as conditions of the relevant melting route. This project is aimed at qualitative displacement of the controlling level of steel making, associated with implementation of melting regimes to enhance the efficiency of the existing controlling routes and providing automatic feed-back control at least in some stages of the melting process. In addition to thegeneral rules of the process even the subjective knowledge of the smelter/operator, as the expert in the field, has to be applied in such interventions. In this respect the expert's systems are considered here, namely, as a means for the diagnostics of"@en . . "0"^^ . . . "http://www.isvav.cz/projectDetail.do?rowId=GA106/02/1128"^^ . .
