| Synopsis: The existing conventional pickling line (No.2 CPL) and the batch type cold tandem mill (No.1 TM) at Mizushima Works were modified into a fully continuous descaling and cold rolling mill in June 1985. On the other hand, we have been operating new KM-CAL since February 1984. As a result, we can produce cold rolled strip using only two processes, that is, the fully continuous descaling and cold rolling mill and KM-CAL. This paper reports new technology necessary for combining a pickling line with a cold tandem mill for a continuous operation; high efficient descaling technique, continuously width changeable trimmer, and advanced flying-gauge changing technology for a large difference in thickness and flow-stress. This modification has brought about improvement in product quality and material yield, an increase in productivity, shortening of production time, and saving of labor cost. New the operation of the new system runs smoothly and is giving expected benefits. |
