Description

Die Erfindung ist ein Zusatz zum Hauptpatent (P 34 34 857.3), das sich auf einen Schieberverschluß für den Ausguß metallurgischer Gefäße bezieht, der eine in einem linear, dreh- oder schwenkbar verstellbaren Rahmen gelagerte feuerfeste Schieberplatte mit einem Verschleißeinsatz in der Durchflußöffnung sowie einen dieser nachgeordneten feuerfesten Wechselausguß aufweist, der von einem mit dem Verstellrahmen oder einem Blechmantel der Schieberplatte kuppelbaren Halter getragen wird. Für einen diesbezüglichen Schieberverschluß besteht die Erfindung darin, daß der Verschleißeinsatz der feuerfesten Schieberplatte dem feuerfesten Wechselausguß zugeordnet und mit diesem austauschbar ist.The invention is an addition to the main patent (P 34 34 857.3), which relates to relates to a slide closure for the pouring of metallurgical vessels, which a frame supported in a linear, rotatable or pivotable adjustable frame fireproof slide plate with a wear insert in the Flow opening and one of these downstream refractories Has interchangeable spout, of one with the adjustment frame or one Sheet metal jacket of the slide plate detachable holder is worn. For one related slide closure, the invention is that the Wear insert of the refractory slide plate the refractory Exchange spout is assigned and is interchangeable with this.

Aufgabe vorliegender Erfindung ist es, durch die Verwendung bestimmter feuerfester Materialien für den Verschleißeinsatz und den Wechselausguß in Abstimmung auf das Material der Schieberplatte, deren Standzeit zu verbessern.The object of the present invention is to use certain refractory materials for the use of wear and the spout in Coordination to the material of the slide plate, their service life too improve.

Dies wird gemäß der Erfindung dadurch erreicht, daß bei aus Zirkonoxid (ZrO2) oder Tonerde (Al2O3) bestehenden Schieberplatte ein Verschleißeinsatz aus Magnesit (MgO) verwendet wird. Auf diese Weise ergibt sich für die Zirkonoxid- oder Tonerdeplatten, die im Durchflußbereich durch relativ schnelle Ausweitung der Durchflußöffnung gegenüber der Gleitflächenabnutzung voreilend verschleißen, ein ausgeglichenes Verschleißniveau, das eine optimale Ausnutzung des Plattenmaterials sicherstellt. This is achieved according to the invention in that a wear insert made of magnesite (MgO) is used in the case of a slide plate consisting of zirconium oxide (ZrO 2 ) or alumina (Al 2 O 3 ). This results in a balanced level of wear for the zirconium oxide or alumina plates, which wear out prematurely in the flow area due to the relatively rapid widening of the flow opening compared to the sliding surface wear, which ensures optimal utilization of the plate material.

Im weiteren ist es im Hinblick auf den Vorschlag des Hauptpatentes, daß der feuerfeste Verschleißeinsatz und der feuerfeste Wechselausguß je nach Gießprogramm bzw. Stahlsorte aus gleichen oder ungleichen Materialien bestehen können, auch vorteilhaft, den feuerfesten Wechselausguß ganz aus Magnesit herzustellen und in die aus Zirkonoxid oder Tonerde bestehende Schieberplatte planeben zu deren Gleitfläche einzusetzen.Furthermore, with regard to the proposal of the main patent, the fireproof wear insert and the fireproof spout depending on Casting program or steel grade from the same or different materials can consist, also advantageous, of the refractory spout entirely Manufacture magnesite and in the zirconia or alumina Insert the slide plate flat to its sliding surface.
