PURPOSE:To know accurately the level required for a burning zone, by always noticing the steel stock groups at a place near the entrance of the burning zone and at a position where the effect of a heating furnace is largest. CONSTITUTION:The steel stock load value is obtained from the shifting speed of the steel stock within the furnace which is obtained from the past achievement of extraction and the estimated extraction of the future. The heat career value is obtained as the representative value of the mean temperature of the steel stock at the entrance 2 of a burning zone. The target value of the output side is obtained as the representative value of the mean temperature of the steel stock at the exit 3 of the burning zone. Based on these values, a required furnace temperature is calculated as the function value for a major unit steel stock group 10. For a minor unit steel stock group 10, a required furnace temperature is calculated as the representative value of the required furnace temperature when each steel stock stays. The weighted average value is set and controlled as a furnace temperature of the burning zone for the required furnace temperatures of both the major and minor unit steel stock groups 10. |
