Steel strips (width 400-1800mm and thickness 1-8mm) produced by a hot strip mill or a cold rolling mill, will have inherent defects due to unbalanced residual stresses in the strip. The residual stresses pronounce in the form of warp, bow, twist or bend when the strip is cut into small pieces using the laser, plasma or oxy-fuel cutting. Industrial users of hot rolled steel strip prefer flat and leveled sheet. Defects in the form of coil set, camber, edge wave, twist or buckle are also not acceptable to such users/industries. The bowing & warpage in the sheet and other defects should be restricted to a minimum extent.
