Abstract

572,111. Granulating slag. BJORKMAN, E. B., and ESCOR INDUSTRIES, Ltd. Nov. 26, 1943, Nos. 19794/43 and 465/44. [Class 82 (ii)] [Also in Group V] Slag falling from a blast furnace, cupola, or the like is elevated and carried along an upwardly-directed shoot by a jet of water from apparatus located beneath the slag outlet, the shoot terminating in a downwardly-directed mouth over a draining apparatus or a combined draining and disposal hopper. As shown, the slag falling from the furnace 1 is forced by a jet 3, which may be arched in cross-section along a shoot 4 having a hinged flap at the discharge end to direct the slag into one of two hoppers 6 provided with openings 8 for discharge of surplus water, the hoppers being provided with gates 11 for discharging the slag into wagons 12. The water from the openings 8 passes into a trough 9 connected to a drain pipe 15, to which is also connected a gutter 10, receiving drippings from the shoot 4. Trays 13 are located under the hoppers 6 to receive water escaping through the gates 11, and are arranged to be moved out of the way when the gates are opened, the water being discharged into trough 14, connected to the drain 15. The jet 3 may be adjustable to be directed on to the top or bottom of the shoot to produce granulated or foamed slag. In modifications, the shoot'discharges (a) into a pivoted vessel having perforated sides and divided into two compartments, so that the weight of slag in one compartment causes the vessel to tilt to discharge the contents into a wagon and to bring the other compartment under the shoot ; (b) into compartments in a perforated drum rotating continuously ; or (c) on to a perforated endless conveyer belt.
