| Abstract Scope |
Edge longitudinal cracks are common defects in the hot rolling process of thin slabs, reducing the yield of plate. To investigated the evolution of crack and edge during reciprocating longitudinal rolling process, the physical model of thin slab rolling process was developed. The extension of crack particles prefabricated 2mm, 3mm, 5mm and 10mm below the slab surface was investigated. Research shows that under the combined action of horizontal and vertical rollers, the width and thickness of the plate are decreased. Material within 5mm of the narrow side corners will extends to the wide side of plate, and folding is found in the new generated corners. After finishing rolling, cracks within 3mm below the slab surface will extended to 0.15mm below the plate surface, and 0.04mm at corners. These cracks may be removed by subsequent treatments. Deeper cracks will not be removed, although the depth from the surface is reduced. |
