Description

Verschleißfeste Rohre für den Blas-- und Spülversatz Im Bergbau werden die geschaffenen Hohlräume durch Blas- oder Spülversatz wieder ausgefüllt.Wear-resistant tubes for blowing and flushing offsets Be in mining the created cavities are filled again by blowing or flushing displacement.

Berge, Sand, Schlacken u. dgl. werden dabei durch Luft oder Wasser durch Rohrleitungen gefördert.Mountains, sand, slag and the like are transported by air or water promoted through pipelines.

Diese müssen so beschaffen sein, daß sie einer mechanischen Zerstörung durch Abrieb Widerstand entgegensetzen, während des Betriebes auftreten den Biegebeanspruchungen, z. B. durch Hochziehen beim Blasen, gewachsen sind und außerdem noch Beanspruchungen durch Schllag, Stoß oder Knickung beim Verlegen ohne Schäden aushalten können.These must be such that they can be mechanically destroyed oppose resistance through abrasion, bending stresses occur during operation, z. B. by pulling up when blowing, have grown and also stresses can withstand knocks, bumps or kinks when laying without damage.

Es ist bekannt, Rohre mit einem zähen, weichen Außenmantel und einer harten, verschleißfesten Innenschicht zu verwenden. Derartige Rohre werden aus Verbundblech hergestellt, das eine weiche, zähbleibende Außenschicht aus Eisen und eine Innenschicht aus härtbarem Stahl besitzt, die verschweißt in dem weichen Rohr festgehalten wird. It is known, pipes with a tough, soft outer jacket and a to use hard, wear-resistant inner layer. Such pipes are made of composite sheet metal made with a soft, tough outer layer made of iron and an inner layer made of hardenable steel, which is welded and held in the soft tube.

Die Herstellung derartiger Versatzrohre ist vergleichsweise teuer, und die Aufgabe der Erfindung erstreckt sich darauf, für den Blas- und Spiülversatz geeignete Rohre, die nach einem anderen, günstigeren Herstellungsverfahren angefertigt sind, zu benutzen.The production of such offset pipes is comparatively expensive, and the object of the invention extends to the blowing and flushing displacement suitable pipes that are manufactured using a different, cheaper manufacturing process are to use.

Die Erfindung besteht darin, für den Blas- und Spülversatz. Rohre zu verwenden, die dadurch hergestellt sind, daß ein schlag-, bruch- und knick- festes Rohr (Mantelrohr) als rotierende Kokille im Schleudergußverfahren mit der verschleißfesten Innenschicht aus verschleißfestem härtbarem Stahl oder verschleißfestem Gußeisen (Hartguß) benutzt wird. Der Schleuderguß gewährleistet dabei eine vorzügliche Verschweißbarkeit und ist lunkerfrei. The invention consists in the blowing and flushing offset. Tube to use, which are produced by the fact that an impact, breakage and kinking solid Tube (jacket tube) as a rotating mold in the centrifugal casting process with the wear-resistant Inner layer made of wear-resistant hardenable steel or wear-resistant cast iron (Chilled cast iron) is used. The centrifugal casting ensures excellent weldability and is free of voids.

Das Rohr mit dem Futter aus härtbarem Stahl wird anschließend gehärtet Dabei wird nur das Futter hochverschleißfest, während der Mantel, aus nicht härtbarem Werkstoff bestehend, weich, zäh und bruchfest bleibt. The pipe with the hardenable steel lining is then hardened Only the lining is highly wear-resistant, while the jacket is made of non-hardenable material Consists of a material that remains soft, tough and break-proof.

Der Schleuderguß kommt auch für Verstärkungen der Innenschicht in Rohren am Ende von Krümmern in Betracht. Mantelrohre mit verschiedenem Außendurchmesser, also z. B. im ersten Teile des Rohres 200 mm, im zweiten Teile 150 mm, können durch den Schleuderguß im Innern auf gleichen Durchmesser bei wechselnder Schichtdicke gebracht werden. The centrifugal casting also comes in for reinforcements of the inner layer Pipes at the end of elbows into consideration. Casing pipes with different outer diameters, so z. B. in the first part of the pipe 200 mm, in the second part 150 mm, can through the centrifugal casting inside on the same diameter with changing layer thickness to be brought.

PATENTANSPRUCH: Die Verwendung von verschleißfesten Rohren für den Blas- oder Spülversatz, die in der Weise hergestellt sind, daß ein Rohr, das schlag-, bruch- und knickfest ist, als Kokille für die im Schleudergießverfahren erzeugte Innenschicht aus härtbarem Stahl oder verschleißfestem Gußeisen dient, wobei das als Kokille benutzte Rohr verschiedene Durchmesser über seine Länge hat. PATENT CLAIM: The use of wear-resistant tubes for the Blowing or rinsing offset, which are made in such a way that a pipe that blows, Is unbreakable and kink-resistant, as a mold for the centrifugal casting process Inner layer made of hardenable steel or wear-resistant cast iron is used, whereby the The tube used as a mold has different diameters along its length.
