Abstract (en)
Feed system for gas flushing of metallurgical vessels comprises a gas pipe (12) enclosed in a refractory pipe (10) of larger internal diameter than the internal diameter of the gas pipe. The outer pipe also encloses a cooling pipe (16) with perforations, through which cool air flows. An independent claim is included for walls and floors of metallurgical vessels fitted with the gas feed system.
