Abstract
The invention relates to apparatus for oxygen cutting pieces of steel. The cutter and trimmer members (5, 10) are positioned in such a manner that the cutting jet (6) is applied to the top face (1.1) of the piece (1) in a substantially vertical direction, while the trimming jet (12) is applied to the bottom face (1.2) of said piece in an oblique direction that remains pointed towards the outlet point (14) of the cutting jet (6), simultaneous cutting and trimming being performed by moving the cutter and trimmer members (5, 10) horizontally in synchronous manner. A sprayer member (11) is also provided for spraying fluid during the cutting process towards molten particles in order to reduce fume emissions.
