Formation and Prevention of Sliver Defects on the Surface of Cold-Rolled Strip

Abstract The feature and formation of and preventive measures against common black and bright slivers on the surface of cold-rolled strip are described. Research reveals that the formation of slivers is closely related to the processes of steel making and rolling as well as conditions of equipment in operation, and, in most cases, due to different factors affecting together. Only when the actual forming mechanism is made clear could effective measures be formulated.
