Abstract
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.
