Abstract

This paper presents the results of a numerical study on the effects of a side guide on the top and tail camber. The temperature distribution on the surface of an actual hot-rolled bar was measured using a thermal imager. The measured temperatures were incorporated with finite element analysis, and the thermomechanical behavior of the hot bar was examined. The installation location of the side guide, length of the side guide, and gap between the bar and the insides of the side guide were selected as the parameters to be investigated. The results show that it is more effective to install the side guide at the position where the magnitude of the camber is larger. It is noted that a longer side guide is more effective than a shorter one in reducing the camber. It is also found that the camber decreases in proportion with the guiding gap.
