In this paper, a measure and control system in steel-making hot stove of ferroalloy mine is presented. The system can measure the temperature of the level surface of aggregate and outlets for discharge by using infrared instruments. We estimate the temperature of the part between bottom and surface, using fuzzy reasoning and expert system. The practice indicated that, applying the intelligent control system is suitable and successful by using computer. We foresee that this technical achievement will have a broad prospect for application.
