Abstract: In a process for dechroming, and/or depleting the MgO content of, steel slags, oxygen is introduced into the liquid steel slag to an extent sufficient for converting iron quantitatively to iron oxide and at least 5% by weight of the iron oxide contained in the slag to iron-III-oxide. The oxidized slag obtained solidifies and is disintegrated, whereupon the paramagnetic portions formed are magnetically isolated and separated from the dechromed slag.

Abstract: The process for making steel and hydraulically active binders uses slags rich in iron oxide, such as steel slag, as oxidizing agent for carbon in pig iron. The slag is reduced, yielding a type of blast furnace slag with improved hydraulic properties.

Abstract: The process is for working up steel slags and/or iron carriers for obtaining pig iron and/or environmentally safe slags. The volume ratio of molten slag to iron bath is chosen to be larger than 0.5 to 1 and the slags are supplemented with SiO2 carriers so as to adjust slag basicity (CaO/SiO2) to between 1.0 to 1.8 at an Al2O3 content of between 10 and 25% by weight based on the slag. Hot blast is top-blown and coal optionally with an inert gas and optionally with oxygen or hot air is blown through the iron bath.

Date Aug. 13, 1998Sulfate cement or sulfate cement aggregates are produced herein by a process in which hydraulically active synthetic slags having slag basicities CaO/SiO2 of between 1.35 and 1.6, Al2O3 contents of 10% by weight to 20% by weight, and iron oxide contents of below 2.5% by weight are mixed with an earth alkali sulfate in an amount of 5% by weight to 20% by weight, based on the overall weight of the mixture. The hydraulically active synthetic slags can be made by mixing at least one member selected from the group consisting of waste incineration slags and blast furnace slags with steel slags to produce a melt and reducing metal oxides contained in the melt. The earth alkali sulfate is selected from the group consisting of crude gypsum, waste gas gypsum, smoke gas desulfurization plant gypsum, gypsum, or anhydrite in ground or comminuted form.

Date Apr. 4, 1996In a method for processing solid residues from refuse incineration plants the slag is melted and heavy metals from the melt (16) are separated for reutilization. The slag is directly transferred from the refuse incineration plant into a first heating chamber (2) and melted there under oxidizing conditions. The melt (16) produced therefrom is transferred to a second heating chamber (3), in which the heavy metal compounds are reduced to their metallic form. Furthermore, additional finely divided residues, such as fly ash, boiler ash and filter dust, are introduced into the second heating chamber (3) via a hollow graphite electrode (19). The melt (16) is then passed on to a third heating chamber (4), in which the residual readily volatile metals are vaporized and the residual non-volatile metals are sedimented. The essentially heavy-metal-free melt is then cooled to form vitreous granules.

Abstract: In a process for granulating and disintegrating molten slags, in particular blast furnace slags, with water, a compressed water jet is directed into the slag and the slag is ejected as the jacket of the compressed water jet. The device for carrying out the process comprises a slag vessel for molten slag including an outlet opening for the molten slag, wherein a lance opens into the axis of the slag outlet opening such that the molten slag is ejected by compressed water or vapor introduced through the lance.
