Description
2373GM2373GM
Die Erfindung betrifft eine Sinterbrunnenanlage für Walzwerke und Stranggußanlagen.The invention relates to a sinter fountain system for rolling mills and continuous casting plants.
&iacgr;&ogr; In Waizwerken und Stranggußanlagen fällt Walzzunder (Walzhaut) während der Bearbeitung der Rohstähle an. Der Walzzunder besteht u.a. aus öl- und fetthaltigen Rückständen und fällt in eine Sinterrinne, die sich unterhalb des Rollenganges befindet. Die Sinterrinne wird kontinuierlich mit Spülwasser gespült, so daß der herabfallende Walzzunder mit dem Spülwasser in den Sinterbrunnen gelangt. Dort erfoigt die Abscheidung von Öl und Fett. Im Mittel befinden sich etwa 40 g/t im Spülwasser, das in den Sinterbrunnen fließt. Das Wasser wird im Kreislauf geführt. Es hat etwa eine Verweilzeit entsprechend der Aufstiegsgeschwindigkeit in Sinterbrunnen und wird dann wieder als Spül-Sprätzwasser der Sinterrinne zugeführt. Eine mittelgroße Sinterbrunnenanlage hat einen Sinterbrunnen mit einem Durchmesser von ca. 10 m. Für vertikale Pumpen ist eine Pumpenvoriage einschließlich Pumpenraum von ca. 700 m3 umbauter Raum erforderlich. Bei der Verwendung von horizontalen Pumpen muß sogar die zweifache Größe des umbauten Raumes geplant und realisiert werden. Die Pumpenvorlage und der Pumpenraum werden direkt am Sinterbrunnen als eine Einheit betoniert, damit keine Setzungen der Baukörper erfolgen, entsprechend ist die Statik für 600 - 800 t Gesamtgewicht ausgelegt. Die Pumpenvorlage und der Pumpenraum werden im Erdreich von ca. minus 10 m bis Oberkante Erdreich angeordnet.&iacgr;&ogr; In rolling mills and continuous casting plants, mill scale (rolling skin) accumulates during the processing of raw steel. The mill scale consists of oil and grease residues, among other things, and falls into a sintering trough located beneath the roller conveyor. The sintering trough is continuously rinsed with rinse water so that the falling mill scale reaches the sintering well with the rinse water. There the oil and grease are separated out. On average, there are around 40 g/t in the rinse water that flows into the sintering well. The water is circulated. It has a residence time roughly corresponding to the rate at which it rises in the sintering well and is then fed back into the sintering trough as rinse spray water. A medium-sized sintering well plant has a sintering well with a diameter of around 10 m. For vertical pumps, a pumping system including pump room of around 700 m 3 of enclosed space is required. When using horizontal pumps, the enclosed space must be planned and implemented to be twice as large. The pump housing and the pump room are concreted directly on the sinter well as a single unit to prevent the structures from settling. The statics are designed for a total weight of 600 - 800 t. The pump housing and the pump room are installed in the ground at a depth of approximately minus 10 m to the top of the ground.
Die beschriebene Ausführung wird weltweit angewendet. Sie bedingt erhebliche Planungs- und Bauarbeiten, was zu hohen Investitionskosten führt.The design described is used worldwide. It requires considerable planning and construction work, which leads to high investment costs.

Die Aufgabe der Erfindung besteht darin, die o.g. Nachteile beim Bau einer Sinterbrunnenanlage zu vermeiden und eine kostengünstige Sinterbrunnenaniage zu entwickeln. Erfindungsgemäß wird die Aufgabe durch die Merkmale der Ansprüche bis 4 gelöst.The object of the invention is to avoid the above-mentioned disadvantages when building a sinter well system and to develop a cost-effective sinter well system. According to the invention, the object is achieved by the features of claims to 4.
Der Sinterbrunnen wird in Zykionform gebaut, ohne die sonst übliche Pumpenvorlage für eine vertikale und oder horizontale Pumpe. Bei Anordnung einer vertikalen Pumpe entfällt neben der Pumpenvorlage auch der Pumpenraum. Die vertikale Pumpe befindet sich im Sinterbrunnen und fördert das Sinterwasser direkt &iacgr;&ogr; aus der Sammelrinne.The sinter well is built in a cyclone shape, without the usual pumping station for a vertical and/or horizontal pump. When a vertical pump is installed, both the pumping station and the pump room are eliminated. The vertical pump is located in the sinter well and pumps the sinter water directly from the collecting channel.
Bei der Verwendung einer horizontalen Pumpe entfällt die Pumpenvorlage, und der Pumpenraum wird wesentlich kleiner als bei bekannten Sinterbrunnenanlagen ausgeführt. Der Pumpenraum befindet sich ca. 4 -5 m höher im Erdreich im Gegensatz zu dem sonst üblichen Pumpenraum einer horizontalen Pumpe mit Pumpenvorlage. Die horizontale Pumpe fördert das Sinterwasser direkt aus der Sinterrinne. Gegenüber den bisher bekannten Sinterbrunnenaniagen wird eine Kosteneinsparung in Höhe von 70 % erwartet.When using a horizontal pump, the pump reservoir is eliminated and the pump chamber is significantly smaller than in known sinter well systems. The pump chamber is located approx. 4 - 5 m higher in the ground in contrast to the usual pump chamber of a horizontal pump with a pump reservoir. The horizontal pump pumps the sinter water directly from the sinter channel. A cost saving of 70% is expected compared to the previously known sinter well systems.
Die Erfindung soll nachstehend anhand von Ausführungsbeispielen näher beschrieben werden.The invention will be described in more detail below using exemplary embodiments.

Bei der Ausführung nach Figur 1 weist der Sinterbrunnen eine Zyklonform auf. Die vertikale Pumpe 1 befindet sich direkt im umschlossenen Raum des Sinterbrunnens, so daß keine Pumpenvorlage und kein Pumpenraum erforderlich sind. Die Pumpe fördert das Sinterwasser direkt aus der Sammeirinne in den Sinterwasserkreislauf.In the design according to Figure 1, the sinter well has a cyclone shape. The vertical pump 1 is located directly in the enclosed space of the sinter well, so that no pump reservoir and no pump room are required. The pump conveys the sinter water directly from the collecting trough into the sinter water circuit.

Vorteilhafterweise sind die Antriebsmotoren im nicht überflutbaren Bereich eingebaut, denn sie werden nur bis zu einer bestimmten technisch zulässigen Baulänge, bedingt durch die zu erwartenden Schwingungen, hergestellt. Es kann zu keinem Produktionsausfall wegen überfluteter Antriebsmotoren kommen.Advantageously, the drive motors are installed in the non-floodable area, because they are only manufactured up to a certain technically permissible length due to the expected vibrations. There can be no production downtime due to flooded drive motors.
Aus Figur 2 ist eine Ausführung ersichtlich, bei der der Sinterbrunnen ebenfalls eine Zyklonform aufweist. Im oberen Bereich des Sinterbrunnens ist ein kleiner Pumpenvorraum vorgesehen, in dem eine horizontale Pumpe 2 angeordnet ist. Der Pumpenraum befindet sich 4 -5 m höher im Erdreich als sonst übliche horizontale &iacgr;&ogr; Pumpen mit Pumpenvoriage.Figure 2 shows a design in which the sinter well also has a cyclone shape. In the upper area of the sinter well, a small pump antechamber is provided, in which a horizontal pump 2 is arranged. The pump chamber is located 4 - 5 m higher in the ground than usual horizontal pumps with pump antechamber.
