PROBLEM TO BE SOLVED: To provide a monitoring/controlling method capable of easily controlling a slag discharge outlet where modeling with numerals is impossible and wasteful time is long without relying upon judgement of an operator. SOLUTION: A future behavior after the passage of wasteful time is predicted using a neural network taking as an input signal measurable process data of a melting furnace. Predicted values of the resulting process data are combinmed with each other as parameters together with past and present process data, and an expert system judges stability of the slag discharge outlet. When the situation is judged stable, a furnace is operated at a rated value while when unstable, the rated value is altered to operate the furnace such that it is stabilized.
