Intelligent system for automatic control of the process of filling the mold

This paper shows fuzzy and neuro-fuzzy intelligent systems for automatic control of mold filling employed in casting plants. The concept of precision mold filling presupposes three key points in the process, i.e., precise pouring of the stream into the basin, maintaining constant level of molten metal in the basin, and finally, elimination of overflow of molten metal from the mold. The possibility of using fuzzy and neuro-fuzzy controls of mold-filling process was tested on a laboratory plant. Instead of molten metal, water was used, due to the approximate value of the Reynolds number of steel (1560–1600 °C) and water at room temperature. Fuzzy and neuro-fuzzy controls of casting process were tested through many experimental attempts which have confirmed the possibility of application of these methodologies in the control of gravity casting process.
