Abstract

A method for oxygen injection in electrical arc ovens for steel production where two oxygen guns at the end of each injection nozzle, placed on the electrical arc oven so that they work just on the melted metal in the area of foamy slag formation. It is intended that oxygen is blown from the injection nozzles covered with slag, at certain moments of the of the operation. The speed of gun on the lower hole is sonic and the speed of the gun on the lower hole is subsonic.
