Abstract (en)
[origin: EP1661645A2] A method for controlling flow through the bottom outlet of a metallurgical vessel with an upper nozzle (3) in the base (1), a lower nozzle (7) below (3), inert gas inlet(s) (13) and a sensor (10) on or in the lower nozzle (7) to measure the thickness of solid in the nozzle (clogging), in which the inert gas feed to the outlet is controlled by means of the signal from the sensor. Independent claims are also included for (1) a bottom outlet as described above (BO1) in which the inert gas inlet(s) and connection(s) are below the upper nozzle (3) and the sensor (10) is on or in the outside of the lower nozzle (7) and is also connected to an inert gas flow controller (2) a bottom outlet as above (BO2) in which the wall of the connecting opening between (3) and (7) is liquid-tight, at least with regard to molten metal, and the two nozzles (3, 7) are surrounded by a gas-tight housing (14) which forms a gas-tight seal with (7) at the bottom of the housing (14), with part of its inside on the outside of (7) and with a thermally-insulating solid between the wall of the connection (3:7) and the housing (14) .
