SUMMARY:The effects of run out table (ROT) condition on edge cracks formation of dual phase steel (1.2 GPa grade)
DESCRIPTION:Recently, the steel applied to car bodies continuously requires high- and ultra-high strength steels. Accordingly, many researchers have conducted research on the development and strength improvement of dual & complex phase steel. As various studies progressed, the strength of steels increased, but a serious problem of edge cracks was formed, and many researchers made efforts to solve the problem. In the past, the cooling temperature was improved during the hot rolling process to reduce the martensite fraction, which directly affects edge crack formation. In addition, our company has conducted tests on various cooling temperatures and pattern changes to effectively roll steel plates. However, a unique phenomenon was observed in which edge cracking occurred at higher cooling temperatures. Therefore, in this study, the effect of ROT condition on edge crack formation was investigated, and the edge crack formation mechanism was discussed in connection with the microstructure analysis.
