Abstract

An oxygen cutting machine (1) is designed for a billets, blooms, slabs or heavy plates in a pair of up and down arranged rails (3) having a novel heat protection plate (6) and no uncooled machine parts below the rails (3), which moves sideways with a drifting work-piece (2) being a clamping system, having a clamp down skid (10) to cover various thickness of work-piece (2) and can be used with so-called cutting push bars (24) for cutting against each other of two oxygen cutting burners (9). A new oxygen cutting burner (9) or nozzle quick exchange system improves use and maintenance. Cutting safety and cut quality are improved by the gas control for pressures and mass flow near the burners. A novel roll deburrer (32) to deburr just oxygen cut strand pieces (2) after the oxygen cutting machine (1) facilitates the to and fro deburring and the transport of extremely short pieces over the deburrer gap.
