Abstract

Schieberverschluß für den Ausguß von metallurgischen Gießgefäßen mit einer gefäßfesten Verschlußplatte und einer Schieberplatte aus hitze­ beständigem Material, die jede mit einer Durchflußbohrung für die metal­ lurgische Schmelze versehen sind und von denen die Schieberplatte mit Füh­ rungsbahnen derart in federnd gelagerten Andruckschienen axial verschieb­ lich geführt ist, daß die Platten mit ihren gegeneinander weisenden Ver­ schlußflächen aufeinander abgleiten und die Durchflußbohrungen in und außer Deckung gebracht werden können, bei der die Andruckschienen (10) frei auf jeweils einer entgegen der Andruckrichtung federnd gelagerten Achse (11) gehalten sind und die Führungsbahnen (8) der Schieberplatte (3) eine gegen die Andruckschienen (10) weisende Wölbung aufweisen. Die wirk­ same Andrucklänge (A) der Andruckschienen (10) ist größer als der in Schubrichtung gemessene Abstand zwischen den Kulminationspunkten der Füh­ rungsbahnen zweier hintereinanderliedender Schieberplatten jedoch kleiner als der Abstand der äußeren Kulminationspunkte dreier hintereinanderlie­ gender Platten. Die Andruckschienen (10) sind beidseitig ihrer wirksamen Andrucklänge mit angefasten Einführungszonen versehen sind. Sliding closure for pouring metallurgical casting vessels with a vessel-tight closure plate and a slide plate made of heat resistant material, each with a flow hole for the metal lurgic melt are provided and of which the slide plate with Füh tion tracks so axially in spring-loaded pressure rails Lich is that the plates with their opposing Ver end faces slide on each other and the flow holes in and can be brought out of cover, in which the pressure rails (10) freely on one spring-loaded against the pressure direction Axis (11) are held and the guideways (8) of the slide plate (3) have a curvature pointing towards the pressure rails (10). The real one same pressure length (A) of the pressure rails (10) is greater than that in Distance measured between the culmination points of the thrust tion paths of two slide plates in succession but smaller than the distance between the outer culmination points of three in a row gender plates. The pressure rails (10) are effective on both sides Pressure length with chamfered insertion zones.
