Continuous steel casting installation with deburrer for cutting burrs and cutting beads on slabs, blooms and billets

摘要

A deburrer machine for cutting burrs (2), which consists out of a rotating deburring body (3) and travelling carriage (6) is foreseen for application especially on longitudinally cut slabs in flow. For deburring the deburring pistons (4) perform a rotary movement around the deburring body axis (21), whereby they approach to the cutting burr (2) from the workpiece side. Therefore the rotation axis is arranged in a way that the deburring pistons (4) turn below the lower workpiece surface outside the workpiece (1) after having finished the deburring procedure in order to lift again against this lower surface. Inside the deburring body (3) is placed a pressure chamber (18) which effects the lifting of the deburring pistons (4). Thereby the air contained in the lower piston guidance (12) is displaced and then the throttled air is led-off via bores in the lower part of the deburring piston (4) in order to dampen the piston movement. The one-piece design of the deburring piston (4) and the deburring cap (25) promises wear- and repair advantages. Other designs of rotating deburrers which derive from the above described promise simpler and on request less space-consuming possibilities.
