METALLURGICAL VESSEL HAVING A PLURALITY OF TRANSPONDERS
First Claim
1. A metallurgical vessel, comprising:
- an exterior of the vessel;
an identification tag at the exterior of the vessel;
the identification tag has a carrier matrix;
the carrier matrix is comprised of a material which is electrically and thermally insulating;
at least two passive transponders embedded in the carrier matrix;
the carrier matrix is comprised of several layers,each layer is above another layer inward from a side of the carrier matrix;
each of the layers has a respective thickness measured inward from the side of the carrier matrix;
the thicknesses of the layers decreases with increasing distance from the outer surface at the side of the metallurgical vessel; and
at least one of the passive transponders is arranged between two adjacent ones of the layers.

Abstract
A metallurgical vessel (2) having an outer surface (2a) and an identification tag (1, 1′, 1″) on the outer surface (2a). The tag has a carrier matrix (11) formed of an electrically and thermally insulating material. At least two passive transponders (3, 3a, 3b) are embedded in the carrier matrix (11). Within a metallurgical plant, a reading station (4) for tracking the path of the metallurgical vessel (2) is arranged at a tracking position. An antenna (5) of the reading station (4) initiates activation of the passive transponders (3, 3a, 3b), provided that the metallurgical vessel (2) is in a sensing range of the reading station (4). A reading unit (6) of the reading station (4) reads out the activated passive transponders (3, 3a, 3b) and transmits the result to an evaluating unit (7) of the reading station (4). The evaluating unit (7) determines which and/or how many of the passive transponders (3, 3a, 3b) were actually activated. The evaluating unit (7) thereafter associates a wear state with all the passive transponders (3, 3a, 3b) of the metallurgical vessel (2) as a whole.

2. An operating method for a reading station arranged at a tracking position within a metallurgical plant, for tracking a path of a metallurgical vessel in the plant, wherein the vessel has an identification tag on the vessel and one or more passive transponders at the tag, wherein the method comprises:
-
causing an antenna of the reading station to initiate an activation of the passive transponders if the metallurgical vessel is located within a sensing range of the reading station; causing a reading unit of the reading station to thereupon read out the activated passive transponders, and communicating a result of the read out to an evaluating unit of the reading station; determining by the evaluating unit which and/or how many of the passive transponders have been activated; and depending on the determination, the evaluating unit assigning to the totality of the passive transponders of the metallurgical vessel a wear state of the transponders. - View Dependent Claims (3, 4, 5, 6, 7, 13, 14)
