Abstract: A process for measuring wear of a refractory lining of a receptacle intended to contain molten metal, containing the following steps: scanning a first surface of the refractory lining using a first laser scanner in order to obtain a first initial set of data representative of the first surface, scanning a second surface of the refractory lining using a second laser scanner, distinct from the first laser scanner, in order to obtain a second initial set of data representative of the second surface, wherein the second surface includes a grey zone for the first laser scanner, the receptacle defining an obstacle located between the first laser scanner and the grey zone during scanning by the first laser scanner, and calculating a final set of data using the first initial set of data and the second initial set of data, the final set of data being representative of a surface of the refractory lining including the first surface and the second surface.

Abstract: A method and a system for determining a mass of feedstock discharged by a conveyor during a first time interval Δt are disclosed. The method includes taking successive digital images of the feedstock in a specific zone of the conveyor being separated by a second time interval δt of smaller duration than the first time interval Δt, for each of the second time intervals δt: computing the advancing distance of a sub-volume of feedstock during the second time interval δt in the specific zone of the conveyor by numerical treatment of the two successive images associated with the second time interval δt; determining at least one transversal height profile of the sub-volume of feedstock; and determining an effective feedstock density for the sub-volume of feedstock. The method further includes computing the mass of feedstock discharged by the conveyor during the first time interval Δt into the metallurgical furnace on the basis of the advancing distance, the at least one transversal height profile and the effective feedstock density, computed or determined for each of the second time intervals δt.
