ABSTRACT:
An improvement in a process for forming a refractory lining on the interior walls of the metallurgical vessel which interior walls are coaxial to the principal axis of the vessel wherein a refractory mass containing a binder is centrifugally slung onto the interior walls in a direction normal thereto while the vessel is at a standstill is disclosed. According to the invention, the refractory mass is initially shaped into balls prior to being centrifugally slung and the balls are centrifugally slung in rapid succession to form a mass jet. Also disclosed, is a device for so slinging a refractory mass on the walls of a vessel comprising a slinger head having a slinger wheel and a motor and at least one supply conduit for supplying refractory mass to be slung. The slinger wheel of the slinger head is disposed on one end of a shaft which shaft is extendable into a vessel, the slinger wheel being connected to an actuatable by a slinger motor. The slinger unit includes a slinger head, the shaft and the slinger motor as well as the supply conduit and is rotatable about the axis which extends in the direction of the entrance to the vessel.
