Abstract: A dross removal device including: a dross robot that is configured to collect a bath surface dross present on a bath surface of a coating bath; a dross sensor that is configured to measure an intensity of infrared light from the bath surface of the coating bath; a dross sensor control device that is configured to specify a position of the bath surface dross according to a temporal change amount in the intensity of the infrared light; and a dross robot control device that is configured to cause the dross robot to collect the bath surface dross at the position specified by the dross sensor control device.
