Zusammenfassung:A new pipe making process was put into operation at the Kashima Steel Works in 1985. The features of this new pipe-making process are 1) high-temperature welding by use of a high-frequency induction welder, 2) removal of weld bead automatically by use of a specially designed bead-cutting tool just after welding and 3) continuous reheating in the reheating furnace in preparation for the next process, namely stretch reducing.
