Abstract
A residual molten material amount detection method and detection apparatus that can detect a residual amount of molten material in a vertical furnace and a method for operating a vertical furnace by using the detection method. The residual molten material amount detection method detects a residual amount of molten material remaining in a bottom portion of a vertical furnace after end of discharge of the molten material. The method includes detecting the residual amount of the molten material by using a difference between a production speed of the molten material and a discharge speed of the molten material that is calculated by using a discharge acceleration, a discharge period, and an initial discharge speed of the discharge of the molten material through a taphole.
