Abstract: A system and method for assessing deterioration of a metallurgical runner using acoustic emissions. The system may be referred to as an acoustic emission runner integrity system (AERIS). The system comprises acoustic emission sensors mounted on the runner. At least some of the sensors can detect acoustic emission signals in the runner. The sensors may be able to emit acoustic emission signals into the runner. The sensors are in communication with a controller. The controller is configured to one or more of identify and monitor deterioration of the runner based on the acoustic emission signals of the sensors. The method comprises affixing AE sensors to the runner, detecting AE signals with the sensors, and assessing deterioration of the runner based on the AE signals of the sensors.
