Abstract
To improve the straight edge seam defect on hot-rolled steel plates, the deformation and temperature distribution of rectangular slabs and chamfered slabs during rolling in a pilot rolling experiment were analyzed in detail using the finite element method. The results showed that the crease formed on the lateral side near the edge of the plate as a result of uneven stress during broadside rolling. The creases rose to the surface with unrestricted spread and evolved into a straight edge seam during the subsequent straight rolling. To eliminate the straight edge seam defect, chamfered slabs were developed and investigated for rolling. The use of the chamfered slabs provided two advantages for rolling: the distribution of the temperature near the edge was ameliorated, and the deformation shape was improved by the chamfered shape. As a result, the risk of forming a straight edge seam defect was reduced by the use of a chamfered slab.
