摘要： A shaft furnace for melting copper solid into copper melt has been controlled by manual operation with reference to the actual storage quantity of the holding furnace so far. The burner air pressure of each zone of the shaft furnace is controlled by the actual storage quantity and the time change of it using Fuzzy Logic. The temperature of copper melt is adopted as another input signal. The proportion of burner air pressure of the zones is revised by the melt temperature. Automatic control basing upon the present invention decreases the fluctuation of storage quantity of the holding furnace.
