The apparatus is intended for processing partly solidified slags transported in ladles out of smelting shop and also for processing slags directly besides blast furnaces and steel-making units (e.g. converters). The apparatus comprises a settling bin provided at its inlet with a water-jet granulator. The settling bin incorporates an elevator with perforated buckets for discharging granulated slag. Elevator pulley shafts are located above the level of water in the bin, the head pulley (the furthest from the granulating compartment) is placed higher than the tail pulley (the nearest to the granulating compartment). A drier is provided at the place of discharge of granulated slag from the settling bin. The settling bin is of a sealed design and is divided by a partition into two compartments, one of which is intended for granulating molten slag, and the other, for discharging granulated slag from the bin by the elevator. A constant level of water in the bin is ensured by an overflow partition. The drier means is a rotary drum drier whose discharge end is provided with a fan and a rotary feeder for discharging dry granulated slag onto belt conveyors for transportation to consumers.

Apparatus for granulating molten slag

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.
