Influence of the Processing Conditions on the Hot-Rolled Manganese Steel Sheet Surface Quality
Journal Title: TEM JOURNAL - Year 2013, Vol 2, Issue 2
Abstract
The subject of interest of this paper is the surface quality of manganese steel sheets. The sheets are produced by hot rolling, on an industrial scale, in the Makstil AD Steel Mill in Skopje. Several surface defects were detected; however, the appearance of edge waves in the hot rolling process was especially analyzed. For this purpose, the change of the geometrical parameters of manganese steel sheets was monitored during the hot rolling process and measurements of the sheet flatness were done. Furthermore, some of the more important technological parameters of the rolling process were followed – reduction degree, temperature, velocity and rolling force, in each of the passes, in the course of the plastic deformation.The knowledge obtained indicates that sheets with quality surface and without edge waves are produced with higher rolling velocities, higher rolling temperatures and lower rolling forces. This finding can serve for defining optimal sheet processing conditions, at which absence of edge waves and satisfactory flatness quality of the steel sheets can be accomplished.
