ABSTRACT:
A gas supply system for a side blowing and/or bottom blowing metallurgical furnace with at least one tuyere which is mounted in the side wall and/or in the bottom of the furnace, wherein gas is conveyed through a line of the gas supply system to the tuyere and through the tuyere to the interior of the metallurgical furnace and emerges there in the form of bubbles. The gas supply system has an inflow restrictor which is assigned to the tuyere or is positioned upstream of the tuyere and reduces or interrupts the gas supply to the interior of the furnace at equal intervals of time.
