Abstract

The study results of the edge zone of more than 300 hot-rolled products of steels 09Г2С, 22ГЮ, 20, К56 produced according to the combined technique of smelting, casting, and subsequent rolling in the conditions of casting and rolling complex are presented. Simulation shows that location of imperfections and defects on the slab serves as a prerequisite for defect formation in coil stock. The most common defects include cracks and scabs. The formation of these defects is often associated with the disclosure of oscillation marks during subsequent hot deformation. In such cases, the defect formation nature is difficult to identify by metallographic methods, since signs of the steelmaking nature of their formation are not observed in the cross section of the discontinuity.
