Device for detecting the erosion of fluid-insufflation bricks for liquid metals

摘要

the detection device includes at least two electrical conductors (2, 4) positioned on the outside of the refractory brick (1), a (4) at least one of the conductor elements extending from the back side of the carton to a predetermined distance from the side as before, in contact with the liquid metal.and the two drivers are installed in an electric circuit detector (8, 9), in such a way that, when the wear of the brick (1) reaches the end of the conductor (4) connecting two conducting elements (2, 4) of the liquid metal is detectable on the indicator device (9).
