Abstract (en)

[origin: EP0561181A2] A tap pipe for a converter or an electric arc furnace should achieve tapping times which are the same as far as possible during as many tappings as possible. For this purpose, the flow cross-sections at the various heights of the tap pipe (3) are, at least in the outflow zone (11) of the tap pipe (3), approximately equal to the cross-sections of that flow profile (So) of the melt which results at a vertical flow of the melt with a bath level of between 30% and 70% of the maximum bath level height (xm). <IMAGE>
