Abstract [en]

In continuous casting of steel, an endless slab is produced. The slabs which can be both wide and thick are beeing cut to proper lengths by high performance gas cutting burners. The burners operate at high oxygen pressure so that the cutting flame is launged at speed up to 1.4 Mach. By optimizing the construction of the cutting nozzles and the oxygen pressure the noise levels can be reduced by about 10 dB(A). If doing so the noise problems still exist as the levels will remain at 90-100 dB(A). In this paper the authors persent a method of enclosing the burner with a shield that is supplied with cooling water, where the water acts both as a cooling media and a noise barrier.
