An apparatus for delivering a refractory mass with a sand-blast head along a ladle-lining surface and parallel thereto in a ladle. The sand-blast head is provided with a movement inside the ladle so as to continuously fill the lining along a helical trajectory and over the entire height of the ladle from the bottom to the top. For this purpose, the apparatus is mounted on a platform installed inside the ladle on a hollow supporting rod through which the mass is fed to the sand-blast head. Provision is made for a contact sensor which senses the current level of the lining plane, and controlled drives of the platform rotation, rod lifting and change in the radial jet of the mass thrown out of the sand-blast head.

Apparatus for lining ladles

The method consists in that a refractory mass is delivered by a sand-blast head along the ladle lining surface and parallel thereto, and, simultaneously, the sand-blast head is imparted such a complex movement inside the ladle as to fill the lining continuously along a helical trajectory and over the entire height of the ladle from the bottom to the top. A backing shaping element is positioned behind the head to ensure a predetermined narrow gap that is to be filled with the refractory mass. The apparatus for effecting the method is mounted on a platform installed inside the ladle on a hollow supporting rod through which the mass is fed to the sand-blast head. The head feeds the mass to apply the same to the inner surfaces of the ladle, while the backing shaping element limits the gap to be filled with the mass behind the head. Provision is made for a contact sensor of the current level of the lining plane, and controlled drives of the platform rotation, rod lifting and change in the radial jet of the mass thrown out of the sand-blast head.
