Abstract (en)

[origin: DE19853761C1] A container (3) on the charging car carries a set quantity of sealant, which is forced to an annular distributor (4) under pressure. This is located above the opening (2). After delivery, pipework (5) from the container outlet is flushed with water. An Independent claim is included for the casting equipment carrying out the sealing process. Preferred Features: The sealant mass is supplied tangentially to the distributor, and emerges from an annular slot or holes, on the distributor underside, for uniform mass distribution around the circumference. Sealant flows from the container into a dosing vessel (6) constructed for pressurization. After receiving the given quantity for sealing, Compressed is introduced into its top, forcing sealant out. Flushing follows. Water is taken from a flushing tank and withdrawn from the pipework ahead of the distributor, to be returned to the flushing tank. Flushing of the annular distributor takes place as the charging car is filled at the coaling bunker.

Abstract (de)

Die Erfindung betrifft ein Verfahren zum Abdichten eines mit einem Deckel verschlossenen Fülloches an einem Koksofen, wobei der Ringspalt zwischen dem Deckel und einem Füllochrahmen mit einer Abdichtmasse vergossen wird, die nach dem Gießvorgang aushärtet. Erfindungsgemäß wird aus einem aus einem Kohlefüllwagen mitgeführten Vorratsbehälter eine für den abzudichtenden Ringspalt vorher festgelegte Menge an Abdichtmasse entnommen und unter Druck einem ringförmigen Verteiler zugeführt, der oberhalb des Ringspaltes positioniert worden ist. Nach Abgabe der vorgegebenen Abdichtmassenmenge wird das an den Vorratsbehälter austrittsseitig anschließende Leitungssystem bis zum Verteiler mit Wasser gespült. Gegenstand der Erfindung ist ferner eine Gießvorrichtung zur Durchführung des beschriebenen Verfahrens. <IMAGE>
