ABSTRACT:
There is disclosed a method for rolling an ingot having a substantially trapezoidal cross-section and coming from a continuous casting machine of the wheel-and-belt type, the method comprising initial rolling of the ingot simultaneously on the side corresponding to the minor base of the substantially trapezoidal cross-section and on the edges of the major base of the cross-section to obtain a cross-section having two orthogonal axes of symmetry. The ingot is than rolled by subsequent two-roll stands. There is also disclosed a rolling mill for carrying out the method, comprising a first three-roll stand with the rolls arranged to provide the desired cross-section having two orthogonal axes of symmetry, and with subsequent two-roll stands.
