Abstract

755,262. Granulating and forming slag. DENMAN ENTERPRISES, Ltd. March 22, 1954 [Feb. 4, 1954], No. 8297/54. Class 82(2). Molten slag produced during the operation of an iron blast furnace is disposed of by providing adjacent the furnace at least one pit suitable for contacting the molten slag with a cooling medium to foam the slag, or for granulating the slag by innundation with the cooling medium, and at least one pit for treating the slag by combined air and spray cooling to produce hard slag, the flush slag being treated in the first pit or pits and the cast slag and other slags of high iron content in the second pit or pits for the recovery of hard slag products. The first mentioned pits for foaming and granulating the slag are substantially as disclosed in Specification 744,068, [Group V]. The addition of a high pressure water supply mains 26 permits the slag coming along the runner 24 to be entrained in the water thus giving a granulated slag product. Alternatively the slag may be accumulated in the ladle 21 and poured in to liquid in the pit to granulate it. The foamed slag is made as fully disclosed in the abovementioned Specification. The hard slag pits are of normal construction.
