Verfahren und Vorrichtung zum Stranggiessen von Rohren

摘要

Tube leaving a continuous casting equipment is led immediately through a protective gas filled chamber in which at temps. lower than the melting point of the metal but above its point of recrystallization, the tube is hot worked over a mandrel. After this the tube may be worked by known methods. Advantageously the hot working is by forging, and immediately after the hot working the tube may be cold worked, preferably in the same operation. The chamber may contain reheating equipment. The method is used with continuous casting of tube of copper, copper alloy, or aluminium.
