Abstract

1. Steel-converter or electric furnace including a refractory tap hole pipe with following features : 1.1 that part (13) of the tapping, contacting the molten metal consists of at least two refractory segments, each extending in one piece in the flow direction A of the melt and forming together a common pass through (17), 1.2 the refractory segments are isostatic pressed parts 1.3 the refractory segments consist of a sintered and/or molten magnesium oxide material of the following composition in weigh percent without consideration of a binder : MgO : Fe2 O3 : Al2 O3 : CaO : SiO2 : 93,0 à 99,0 0,2 à 3,0 0,1 à 0,4 0,6 à 3,0 0,1 à 1,5
