US 10,859,316 B1 · Predictive refractory performance measurement system

Abstract

A measurement system is provided for predicting a future status of a refractory lining that is lined over an inner surface of an outer wall of a metallurgical vessel and exposed to a heat during which the refractory lining is exposed to molten metal. The system includes one or more laser scanners and a processor. The laser scanners are configured to conduct a plurality of laser scans of the refractory lining when the metallurgical vessel is empty. At least one of the laser scanners is configured to laser scan the refractory lining prior to the heat to collect data related to pre-heat structural conditions of the refractory lining. At least one of the laser scanners is configured to laser scan the refractory lining after the heat to collect data related to post-heat structural conditions of the refractory lining. The processor is configured to predict the future status of the lining.
