Abstract: The invention involves a process for the oxygen cutting of slabs—using one or more oxygen cutting torches—and a device for implementing the process. The process includes the steps of hanging the slab (16) using one or more electromagnets (14) separated from the slab (16) by a non-magnetic device or medium (such as air); causing a relative motion between the cutting torches (18) and the slab (16); using a carrying device (15) acting on the slab on the same side of the slab (16) as the electromagnet (14); and activating the cutting torch (18) in order to cut the slab (16) when it is transported past the cutting torch (18).
