This paper analyzes the control of Al2O3 inclusions in high strength IF steel containing phosphorus. The inclusion statistics and two-dimensional morphology samples with slab thickness 1/8, 1/2 7/8, hot rolling, cold rolling continuous annealing processes were observed compared by ASPEX SEM. In addition, three-dimensional extracted from electrolysis original process compared. results show that:...

The quality of steel strip produced in a wide strip rolling mill depends heavily on the careful selection of initial ground work roll profiles for each of the mill stands in the finishing train. In the past, these profiles were determined by human experts, based on their knowledge and experience. In this research, a Self-Organising Migration Algorithm (SOMA), a heuristic optimisation algorithm,...

Different from the cross-section profile defects caused by uneven roll wear or external forces during hot finishing rolling, edge warping defect often occurs and has special local characteristics. However, cause control method of are still unclear. By superposition calculating shape, it is found that high-order comprehensive gap contour formed bathtub-shaped thermal parabolic original shape mai...
