摘要

Electroslag remelting is one of the most important special metallurgy technologies. To obtain electroslag remelting steel with characters of high purity, dense organization, and good mechanical properties, the temperature field and remelting speed of the electroslag molten bath must be constant, which means material's uninterrupted feeding and feeding speed must be controlled. In this paper, based on soft-detection technique, electrohydraulic proportional control technique, modern detecting technique, and intelligence control technique, the material uninterrupted feeding system of the electroslag remelting furnace was designed; the system's three-dimensional model was established; the mathematical model of the surplus-ingot length soft-sensing detecting system was established; the S-style position control curve of the ingot was designed. The research results were applied to an experimental electroslag remelting furnace, and dissection research of the experimental product was made, and system control curves and the experimental production dissection results were obtained. It was found that the material uninterrupted feeding system and the feeding speed control system introduced in this paper meet the production process and technique requirements of large electroslag remelting furnace and provide references for design and application of new-style electroslag remelting furnaces.
