Abstract
A furnace slag amount estimation device (1) includes: an input unit (11) configured to receive input data including furnace shape data for a converter, data on components and temperatures of molten metal and slag before start of or during blowing treatment, and slag height data in a furnace of the converter; a slag bulk density calculation unit (13) configured to calculate a slag bulk density after the converter is tilted, using the input data and a model; a slag volume calculation unit (14) configured to calculate a slag volume in the furnace after the converter is tilted, using the slag height data after the converter is tilted, the furnace shape data, and a model; and a slag weight calculation unit (15) configured to calculate a slag weight in the furnace after the converter is tilted and slag is discharged, using the calculated slag bulk density and the calculated slag volume.
