PROBLEM TO BE SOLVED: To provide a method of detecting dust deposit in which a state of dust deposit in a gas duct of a converter can be easily detected, and a detection device of the dust deposit.SOLUTION: There is provided a detection method for detecting dust deposit in a converter OG duct 1 which is arranged above a converter 1 and through which gas from the converter 1 passes. A thermometer 20 arranged on a wall surface in the converter OG duct 11 measures temperature in the converter OG duct 11, and a state of the dust deposit in the converter OG duct 11 is determined based on at least one of temperature changes of measured temperature measured by the thermometer 20 after start of blowing and relationship between a previously set threshold value and the measured temperature. |
