This is the final report on the development of improved power input control for ladle furnaces. Lower refractory wear and high energy efficiency are particularly hard to achieve in large and powerful ladle furnaces, but research has suggested that maintaining submerged arcs and the optimum arcing mode may by the key to success in this area. A modular parallel processing computer system has been developed which rapidly assesses the state of one or more arcs using digital signal processing (DSP) and image processing, If the arcing is not as required, the system decides upon a suitable control action and communicates control information to the ladle furnace control equipment and operator. The computer implements enhanced power input control (EPIC).
