Abstract
In a process for the treatment of metal melts, such as steel melts, with scavenging gas in a ladle under reduced pressure, inert scavenging gas is supplied through a plurality of inlet devices, such as scavenging gas supply bricks, built into the ladle bottom. In order to produce a flow of scavenging gas of low energy loss and free of counter-flow in the region of gas bubbles ascending through the melt, at least two scavenging gas inlet devices are disposed in the bottom of the ladle at a spacing which is equal to from 0.3 to 0.8 times the internal radius of the bottom of the ladle.
