Abstract：Through statistical analysis and comparison experiment, the plate straightening process, the possibility of press of cubic iron oxide under working roller pressure into the steel plate surface in the powerful straightening machine and the defect caused on the plate surfacewere proved. And the morphology and characteristics of defects were summarized; the process and reason of the press of iron oxide were analyzed. It points out that the generation of the cubic ferric oxide, iron oxide under external bending stress cracking and accumulation, and the perpendicular pressure to the plate surface during the straightening process were the three necessary conditions; it also points out several key technology points which affect the press of iron oxide during plate straightening and how to prevent or reduce the defect of press of iron oxide during straightening process.
