Description

Die Erfindung betrifft eisenarmierte Schleuderguß-Rohre aus mineralischen Stoffen, wie Basalt, Granit, Schlacke oder ähnlichen Silicaten.The invention relates to iron-reinforced centrifugal cast pipes made of mineral Substances such as basalt, granite, slag or similar silicates.

Die geschleuderten, hochverschleißfesten Rohrstücke eignen sich ganz besonders zum Ausfüttern von schmiedeeisernen Rohren, wie dieselben seit langem im Bergbau als Versatzrohre oder aber auch über Tage in Rohrleitungen, in denen aggressive Güter, wie Koksstaub, Aschebrei usw., gefördert werden, Verwendung finden, um diese Anlageteile vor Verschleiß zu schützen.The hurled, highly wear-resistant pipe sections are very suitable especially for lining wrought iron pipes, as they have been for a long time in mining as backfilling pipes or above ground in pipelines in which aggressive goods, such as coke dust, ash pulp, etc., are conveyed, are used, to protect these system parts from wear and tear.

Das Neue der Erfindung wird darin gesehen, daß das aus Basalt oder aus dergleichen mineralischen Stoffen oder Schlacke bestehende Rohr eine Metallarmierung als Verstärkung hat, die um den ganzen Umfang und über die ganze Länge des Rohres führend, in die Masse der Rohrwand eingebettet und eingeschlossen ist. Das Schleudern -von Rohren aus verschiedenen Metallen und Mineralien ist bekannt, neu jedoch ist das gleichzeitige Miteinschleudern einer Armierung in Form von dünnem Draht oder Drahtgeflecht, wodurch die Biege- und Schlagfestigkeit von Rohren aus Silicatstoffen ganz bedeutend erhöht, also unempfindlich gegen äußere und innere mechanische Beanspruchungen wird. Diese Eisenarmierung wirkt sich besonders vorteilhaft bei obenerwähnten Bergeversatzrohren aus. Wenn durch Schlagbeanspruchung oder aus sonstigen Gründen ein inneres Futterrohr zu Bruch geht, dann wird sich bei einem nichtarmierten Rohre das Bruchstück aus dem Verband lösen, wodurch leicht Stopfer in der Leitung entstehen können, ganz abgesehen davon, daß sogar ein Teil der Innenausfütterung, von dieser Bruchstelle ausgehend, von dem Versatz mitgerissen wird. Bei einem eisenarmierten Rohr jedoch wird das Bruchstück durch das Drahtgeflecht fest in seiner Lage gehalten, und der innere Durchgang bleibt trotz des Bruchrisses gesichert.The novelty of the invention is seen in the fact that the basalt or a metal reinforcement pipe consisting of the same mineral substances or slag as reinforcement that has around the entire circumference and along the entire length of the pipe leading, embedded and enclosed in the mass of the pipe wall. The spin -of pipes made of various metals and minerals is known, but is new the simultaneous throwing in of a reinforcement in the form of thin wire or Wire mesh, which increases the flexural strength and impact resistance of pipes made of silicate materials significantly increased, i.e. insensitive to external and internal mechanical loads will. This iron reinforcement is particularly advantageous in the case of the recovery pipes mentioned above the end. If an inner casing pipe is due to impact stress or for other reasons breaks, then in the case of a non-reinforced pipe the fragment will come off loosen the bandage, which can easily cause blockages in the line apart from the fact that even a part of the interior lining, from this break point starting from the offset is carried away. With an iron-reinforced pipe, however the fragment is held firmly in place by the wire mesh, and the inner passage remains secured despite the fracture crack.

In der Zeichnung zeigt die Darstellung ein geschleudertes Rohr in Längs- und Querschnitt. Die Darstellung zeigt ein geschleudertes Rohr a, wobei die Eisenarmierung b an der äußeren Peripherie deutlich zu erkennen ist. Diese Eisenarmierung erstreckt sich auf den ganzen Umfang und Länge des Rohres.In the drawing, the illustration shows a pipe thrown in Longitudinal and cross-section. The illustration shows a hurled pipe a, where the Iron reinforcement b can be clearly seen on the outer periphery. This iron reinforcement extends to the entire circumference and length of the pipe.
