ABSTRACT
Figure 7-23 Measured AGS distributions for the two-pass bar rolling test. B, C, D, and E represent roll/material contact area, and A stands for roll gap area where the roll does not contact material. Numbers in abscissa 1-4 stand for the numbers 1-4, in Fig. 7-20. 0 represents the initial state of the specimen. (From Kim et al., 2003.)
evolution behavior. Furthermore, considering the monotonie compressive loading in plate rolling, the area in contact with the work rolls during the rolling sequence should be identified clearly for more accurate analysis, because bar rolling is of characteristic of cross-compressive loading (loading direction varies alternatively).
