Document Type and Number:
Japanese Patent JP7400786
Kind Code:
B2
Abstract:
To provide a technology that estimates a refractory remaining state in a smelting vessel in real time during operation of a metal smelting furnace.SOLUTION: A method of estimating a refractory remaining state for estimating a remaining state of a refractory in a metal smelting furnace during operation in real time, in which the vibration of the furnace caused by a vibration of a bath surface of a molten metal in the metal smelting furnace is measured using an acceleration sensor, and a remaining state of a refractory is estimated based on the fluctuation of one or two of an intensity and a frequency of the above described vibration.SELECTED DRAWING: Figure 3
