Abstract: The invention concerns a fiber burner-brick 5, 13, 24, 34 with a fiber part 7, 15, 25, 35, 46, 54 made of refractory fibers. In order that the said brick be of low eight, insensitive to mechanical and thermal stresses and be characterized by fine and uniform porosity, the fiber part 7, 15, 25, 35, 46, 54 is composed of individual fiber strips 9, 10, 18, 19, 20, 21, 26, 36, 47, 55 each consisting of mutually displaceable fibers intrinsically cohesive and only by themselves, the fiber strips 9, 10, 18, 19, 20, 21, 26, 36, 47, 55 being compressed against each other by a compression system 8, 16, 27, 28, 29, 30, 31, 38, 39, 44, 45, 51.

Abstract: A flushing arrangement for a metallurgical vessel having a metal outer shell, a bottom lined with a permanent lining, on which adjacently arranged refractory bricks are applied as working lining, and pipes inserted in recesses of the bricks at predetermined sites and having flat cross sections, through which flush gas flows. In order to provide a flushing means that is simple to produce and install and offers a great safety with regard to a melt breakthrough, a rigid supply pipe for flush gas is led through the metal outer shell, reaching into the permanent lining. To its end lying in the permanent lining, at least two, yet at most four, distributing pipes are welded. They diverge from the end of the supply pipe and pass over into straight pipe sections arranged in recesses of the bricks of the working lining. The distributing pipes that are connected to one supply pipe each enclose one brick.
