Abstract
Das Verfahren dient zur Entfernung von an Oberflächen von Behälterwänden haftenden Schichten mittels Sprengstoff ladungen mit Tiefkühlung der Behälterwand. Nach erfolgter Tiefkühlung der Behälterwand werden an der Außenoberfläche des Wandteiles 1 zahlreiche Sprengschnüre 2 angeordnet, die nach Detonation die Entfernung der innenliegenden Schicht von der Wand 1 des Behälters bewirken. The method is used to remove surfaces from Layers adhering to the container walls using explosives loads with freezing of the container wall. After done Freezing the container wall are on the outer surface of the Wall part 1 numerous detonating cords 2 arranged after Detonation the removal of the inner layer from the Effect wall 1 of the container.
