ABSTRACT:
The invention relates to a method for protecting the refractory lining of a metallurgical reaction vessel containing a smelt consisting of metal and slag, the reacting agents for the smelt being fed to the metal bath through introducing means disposed below and above the bath surface, and the gases escaping from the smelt being afterburned with oxidizing agents in the gas space, i.e. in the space above the still smelt, whereby gaseous reacting agents and/or gases acting inertly in the metal bath are fed to the smelt below the bath surface, and the total refractory lining surface in the gas space of the metallurgical reaction vessel is wetted by partial amounts of smelt in the form of drops, splashes, liquid portions rising or ejected eruptively and like a fountain and/or by wave or sloshing motion of the smelt.
