PATENT-ANSPRUCH : Verfahren zur Herstellung glatter, schwarzer Oberflächen beim Walzen von Stahlrohren durch Einwirkung von aufgegossenem Wasser, dadurch gekennzeichnet, dass nach der Formgebung bei ununterbrochenem Walzverfahren das Stahlrohr fortwährend der Einwirkung des Wassers bis zum Erkalten ausgesetzt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for producing smooth, black surfaces when rolling steel pipes by the action of poured water, characterized in that after shaping with an uninterrupted rolling process, the steel pipe is continuously exposed to the action of water until it cools. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
