Title
(EN) PREDICTIVE REFRACTORY PERFORMANCE MEASUREMENT SYSTEM
(FR) SYSTÈME DE MESURE DE PERFORMANCE RÉFRACTAIRE PRÉDICTIVE
Abstract
(EN)
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.

La présente invention concerne un système de mesure prévu pour prédire un état futur d'un revêtement réfractaire qui est doublé sur une surface interne d'une paroi externe d'un récipient métallurgique et exposé à une chaleur pendant laquelle le revêtement réfractaire est exposé au métal fondu. Le système comprend un ou plusieurs scanners laser et un processeur. Les scanners laser sont configurés pour conduire une pluralité de balayages laser du revêtement réfractaire lorsque le récipient métallurgique est vide. Au moins l'un des scanners laser est configuré pour balayer par laser le revêtement réfractaire avant la chaleur pour collecter des données associées à des conditions structurales de préchauffage du revêtement réfractaire. Au moins l'un des scanners laser est configuré pour balayer par laser le revêtement réfractaire après la chaleur pour collecter des données associées à des conditions structurelles post-chaleur du revêtement réfractaire. Le processeur est configuré pour prédire l'état futur du revêtement.
