ABSTRACT:
The detection device comprises at least two electrically conductive elements (2, 4) arranged outside the refractory brick (1), at least one (4) of the two conductive elements from the rear face of the brick to a predetermined distance from the front face, in contact with the liquid metal, and the two conductive elements being connected to an electrical detection circuit (8, 9), in such a way that when the wear of the brick (1) reaches the end of the conductive element (4) the two conductive elements (2, 4) are put into contact with one another by the liquid metal, and this can be detected on the indicator instrument (9).
The invention is used especially in steel metallurgy.
