Abstract
The invention provides a method and apparatus for oxygen cutting continuously cast billets, in which a cutting member (8) and a trimming member (9) are positioned relative to the billet to be cut (1) by taking a reference directly on the billet (1) by means of a moving clamp (7), after which the cutting member (8) and the trimming member (9) are lowered parallel to the side faces of the billet so as to cut the billet progressively downwards by attacking one of its side faces horizontally, while simultaneously trimming the cutting bead that forms on the other side face by attacking said other side face continuously in a downward direction.
