Abstract (en)
[origin: WO2004046390A1] The aim of the invention is to damp or suppress oscillations ( </= BACK-ATTACK >/= effect) in sidewall or base blowing converters, used in particular to produce carbon steel or stainless steel. To achieve this, the gas supply system (3) for the converter comprises an inflow restrictor device (7), which is positioned upstream of or associated with the jets (5) and which periodically reduces or interrupts the gas supply to the interior of the furnace.
