Abstract

1. A permeable refractory element for introducing a stirring fluid into a molten liquid metal bath held in a metallurgical vessel, such as an oxygen-blown (through the top) steelworks converter, element to be inserted for walling and, usually, for lining at the bottom of said vessel and comprising an unobstructed face for the stirring-fluid outlet, and characterized in that it comprises at least two electroconductive bodies (16, 6), arranged according to the thickness of the element and insulated from one another, one of their ends being flush with the outlet face (8) for the stirring fluid, the other end being connected to electric-supply source (17) so as to make up two live terminals, of opposite polarities, of an open electric circuit, said circuit including at least one audible-indicating means (18), showing whether the circuit is "open or closed".
