    Abstract: In a process for the preparation of cement from metallurgical slags, in which liquid slags from reduction processes and steelworks processes, e.g. blast furnace and converter slag, are mixed together and mixed with lime the procedure is such that in a first cooling phase at temperatures above 1000 DEG C., and preferably above 1200 DEG C., the cooling is slower than in a subsequent second cooling phase and that the solidified product obtained is granulated and/or ground in order to obtain directly cement with improved hydraulic properties, in particular increased final strength.

Date Jan. 12, 1995The reactor (1) that is used to melt combustion residues incorporates a vertical partition wall (4) that incorporates return flow openings (7) and an overflow (6), wherein foamed slag is produced in the chamber (3) by the injection of gases through base nozzles (10) and the foam collapses in the second chamber (5) or the return flow channel. The liquid slag is drawn off through the taphole (11) after the desired conversion.

    Abstract: The method for granulating liquid slag melts, in particular blast furnace slag, in which the melt (2) is ejected into a cooling chamber via a slag tundish (1) and in which fluid under pressure, in particular compressed gas, vapor or pressurized water, is injected in the direction of the slag exit (6) in order to eject said liquid slag, is characterized in that the pressure fluid jet discharges into a throttle pipe (3) which is immersed in the slag bath and whose lower edge is mounted so as to be adjustable in the height direction (4). The corresponding device comprises a lance (7) which is surrounded by a height-adjustable throttle pipe (3) whose lower edge (5) is immersed in the slag bath (2) contained in the tundish (1) and forms a throttling cross section between the slag exit (6) and the slag bath (2).

    Abstract: A method for processing steel slags and optionally iron carriers such as, e.g., electric furnace slags, converter slags, dusts derived from steel production, mill scale or secondary metallurgical residues, in which the molten steel slags or iron carriers are supplemented with chromium ores or chromium-containing and/or nickel-containing dusts in order to adjust a slag basicity of 1.2 to 1.6, whereby the bath temperature is maintained at above 1600° C., in particular between 1650° C. and 1800° C., and a carbon-containing iron bath is provided or formed. In addition to environmentally safe slags, a high-grade ferrochromium alloy may be recovered, thus enhancing the economy of the method.

Date Aug. 15, 1996To produce pig iron or steel and cement clinker from slags it has been proposed to react iron-oxide containing liquid slags, such as, e.g., steelworks slag, with iron oxide carriers, such as, e.g., ores, cinders or the like and lime to a ferrite-containing slag and to reduce the formed ferrite slag in a reduction reactor, such as, e.g., an iron bath reactor, whereupon the sinter phase is discharged as a clinker.

    Abstract: The invention relates to a method for processing steel slags and optionally ferriferous materials such as e. g. electric furnace slags, converter slags, dust produced during the manufacturing of steel, rolling mill cinders or secondary metallurgical tailings. According to the inventive method, the molten steel slags or ferriferous materials are mixed with chrome ores or with dust containing chrome and/or nickel in order to adjust the slag basicity to a level ranging from 1.2 to 1.6, whereby the bath temperature is maintained at a temperature greater than 1600 degrees C, especially between 1650 and 1800 degrees C, and an Fe bath containing carbon is provided or configured. In addition to the environmentally compatible slags, a high-quality ferrochrome alloy can be obtained, whereby the economic efficiency of the method is improved. 8 claims, 7 figures
