    Abstract: PCT No. PCT/AT96/00085 Sec. 371 Date Dec. 31, 1996 Sec. 102(e) Date Dec. 31, 1996 PCT Filed May 30, 1996 PCT Pub. No. WO96/34989 PCT Pub. Date Nov. 7, 1996In a process for the production of hydraulic binders, crude steel and/or alloys, such as, e.g., FeCr or FeV, from basic steel slags containing chromium and/or vanadium, the liquid steel slag is mixed with an additive selected from the group consisting of blast furnace slag, electric arc furnace slag, dusts from steel production, metallic waste substances or refuse incineration residues and/or with acid additives for lowering the viscosity, whereupon steel is sedimented out of the liquid slag and the remaining slag in a first reduction stage is reduced to metallic iron having an iron oxide content of below 5 wt. % and above 1 wt. %, whereupon the remaining slag melt in a second reduction stage having a higher reduction potential as compared to the first reduction stage is further reduced to metallic Cr or V or ferroalloys thereof and the hydraulically active slag is separated.

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: PCT No. PCT/AT94/00185 Sec. 371 Date Aug. 31, 1995 Sec. 102(e) Date Aug. 31, 1995 PCT Filed Dec. 1, 1994 PCT Pub. No. WO95/15402 PCT Pub. Date Jun. 8, 1995A molten melt of slag and grinding material is introduced into a mixing chamber to which a cooling and mixing agent is injected, the agent being compressed air, water or an air/water mixture which serves to cool the melt and form vapor and solidified particles. These are passed through a diffuser and are discharged as a jet which is directed to particle disintegrating means.

    Abstract: In a process for producing pig iron and cement clinker in a melting gasifier (3), the charge is at least partially preheated and if required deacidified and prereduced or scrap is used as charge. Coal is blown into a fluidized bed (7) and is gasified, reducing the charge, and pig iron (8), as well as slag (9), are drawn off in the liquid state. If required, the batch of lime introduced into the melting gasifier (3) is preheated and calcined together with a partial amount of iron ore in a preheating shaft (1) and is fed in according to the desired clinker composition.
