Abstract
Water-cooling tubes are extensively used for cooling hot moving strands, for instance hot-rolled rod. In order to avoid the braking action of the water within the tubes, the invention provides for the water to be expelled from the tubes before the leading end of the strand passes through the tubes, by blowing air into the tubes.
