Abstract

Improvement of temperature-measuring and slag-combing for smelting process in main frequency furnace is conducted based on practical production. Temperature of the liquid steel and whether the slag exists in the surface can be identified through analyzing the surface image during smelting processing based on the digital image treatment technique. The terminus of melting process is determined by controlling robots to comb slag and by controlling input power of the main frequency furnace to realize the temperature-increasing and holding of the liquid steel. The application of the system can greatly improve the automatic level of smelting process.
