thickness in cold rolling, a series of rolling mills may be used to share the total reduction. One important application of cold rolling is the removal of yield point from mild steel sheets using skin pass rolling [temper rolling]. In this the steel sheet is given a light reduction of to % . Such a process eliminates yield point elongation.
and finishing of individual parts in the cold state. The general trend today is for testing to also take place on the hot product in the rolling mill itself (Figure 1). As plants are being modernized and automated for greater efficiency, hot testing is becoming an integral part of the production process. Its advantages at this stage are twofold.
