Abstract

The invention relates to a device (1) for cleaning the outer shell of two immersion tubes or nozzles that are arranged next to each other and lowered into the melt of vacuum degassing units for the treatment of the liquid steel, comprising a spectacle-like scraper ring that is adapted to the contour of the nozzle pair, can be placed against the outer shell thereof and has wiper means (5) such as teeth, bits, peripheral closed sheet metal construction or the like. For a cleaning device (1) of said kind, a very stable and robust construction having variable operation modes at the same time is to be made possible. Therefore, the scraper ring comprises two scraper ring halves (4a, 4b) that can be moved toward each other and away from each other orthogonally to the longitudinal extensions thereof.
