IPC: B21B3/02
Filed: 2002-08-28
Abstract: The invention relates to a method for cold-rolling strips consisting of, inter alia, special steels and/or nonferrous metals, in a multi-stand tandem rolling mill. The first stand(s) carry out comparatively high reductions and the last stand(s) determine the surface quality of the strip, with a relatively low reduction. The aim of the invention is to improve the capacity of the tandem rolling mill in terms of thickness reduction and in terms of the surface quality of the rolled strips. To this end, an emulsion is used as a coolant and lubricant for the first passages of the strip through the tandem rolling mill with relatively high reduction. The adhesive coolant and lubricant film is then squeezed off the strip following removal from the roll gap of the last emulsion-operated stand. Rolling oil is used as a lubricant for especially the last passage(s) through the tandem rolling mill with relatively low reduction. The invention also relates to an installation for carrying out the inventive method.

Abstract: Die vorliegende Erfindung bezieht sich auf das Gebiet der Beseitigung von Hindernissen im Untergrund. Die vorliegende Erfindung stellt ein Verfahren und eine Vorrichtung zur segmentierten Beseitigung eines bestehenden Rohrschachts (1) bereit. Mit einem Gehäuse (3), einem Wasserstrahlschneidkopf (4), einer Motorvorrichtung (5), einer Drehscheibe (6), einem Drehrohr (7) und einer Verbindungsvorrichtung (8) kann sich die Vorrichtung in einem Rohrschacht zusammen mit einem flexiblen Hochdruckrohr auf und ab bewegen. Daher kann sich der Wasserstrahlschneidkopf (4) zu Positionen in verschiedenen Tiefen im Rohrschacht bewegen. Eine Druckerhöhungspumpe fördert Wasser in einen Wasserspeichertank, und das Wasser strömt nacheinander durch das flexible Hochdruckrohr, die Verbindungsvorrichtung (8) und das Drehrohr (7) und wird dann mit Hilfe des Wasserstrahlschneidkopfes (4) ausgestrahlt, um das Hochdruckwasserschneiden am Rohrschacht durchzuführen. Dadurch kann der Rohrschacht in Stücke geschnitten werden, Teile eines Rohrsegments können maschinell ausgegraben werden, und die Beseitigung von Hindernissen für den Rohrschacht wird realisiert. Der Einsatz einer Vibrationsramme, eines Vollrotationsbohrers und dergleichen wird vermieden. Daher reduziert das Gerät die Auswirkungen auf die Umwelt, ist bequem, schnell und sicher zu bedienen und löst die Probleme bei der unterirdischen Hindernisbeseitigung, wie z.B. die Auswirkungen auf die Umgebung und die hohen Produktionskosten.
