- RU 2 241 770 C1 describes a mixture of iron ore comprising 10 to 30 wt% of a fine sand fraction having a grain size of 0.25 to 0.074 mm and 70 to 90% of a clay mineral fraction having a particle size of less than 0.074 mm.
- the composition is used for the production of iron ore pellets and has a high strength.
- GB 805 938 A describes a method for sintering residues from metalworking using lime and clay minerals as binders.
- Example 2 describes the sintering of an ore using clay mineral as a binder as well as lime. As clay mineral bentonite can be used.
- GB 825 440 A describes a process for briquetting ores in which a binder is added to the finely divided ore.
- the binder consists of a finely divided clay / glue mixture. Subsequently, a pressing operation is performed.
- JP 2002 285251 A describes a method for improving the permeability of a sintered layer and increasing productivity in the production of a sintered ore, in which a clay mineral compound is added to the sintered raw product and the mixture is sintered in a conventional manner.
- JP 2005 097687 A describes microparticles which are mixed with a raw material to be sintered for the production of iron and granulated.
- ore containing ore sizes metal and / or metal oxide-containing fines having a mean grain diameter of less than 1 mm, preferably from 0.05 mm to 1 mm, more preferably from 0.2 to 0.7 mm, in particular of 0.1 to 0.5 mm understood.
- An essential process step of the method according to the invention is the use of a lime-based material together with a clay mineral-containing raw material as a binder.
- the lean clay has, which consists of at least 60 wt.% Fine quartz and 20 to 40 wt.% Kaolinit and optionally subordinate micas.
- Excellent is a clay mineral-containing raw material, the 70 to 90 wt.%, Preferably about 83 wt.% Of silica, 5 to 20 wt.%, Preferably about 13 wt.% Of alumina, 0.2 to 1.5 wt.%, Preferably about 0.7 wt% Fe 2 O 3 and 0.1 to 1 wt%, preferably about 0.4 wt% potassium oxide.
- the clay mineral-containing raw material with a substantially continuous particle size distribution.
- the metal and / or metal oxide-containing fines and the mineral binder are mixed together.
- the mixing of fines and binders can be carried out in a variety of ways known to those skilled in the art.
- the mixing of fines and binders in a mixing unit is particularly simple.
- metal and / or metal oxide-containing fines the most diverse fines can be used.
- the term "metal and / or metal oxide-containing fines" are understood according to the invention as powdery to finer materials. These preferably have average particle sizes of 0.01 to 10 mm. The use of materials having average particle sizes of from 0.05 to 3 mm, in particular from 0.1 to 2 mm, has proven particularly suitable. Preferably, up to 50 wt.% Of the particle sizes of the fine material in the grain size range between 0.1 and 2 mm.
- the binder contains a lime-based material.
- Lime, limestone, quicklime, slaked lime, hydrated lime, dolomite, dolomitic lime, dolomitic lime, dolomitic lime hydrate and mixtures thereof are particularly suitable according to the invention.
- offset additives for lowering the hardening temperature such as, for example, low-melting silicatic substances, in particular a glass powder and / or phonolite, can be added to the mixture.
- agglomerates produced by a sintering process have proven to be particularly suitable.
- the advantages of sintering include the fact that the agglomerates can be pre-reduced and losses in the furnace can be avoided.
- the course of the sintering process is known to the person skilled in the art and may, for example, be as follows. It is first produced a mix containing fine ores, recycling substances, fuel, especially coke breeze, mineral binder and Sintereigenabsiebung. This mix is mixed with water and layered on a sintered belt. The fuel contained in the mixture is ignited, for example, by natural gas and / or blast gas flames. The induced draft fan located under the sintering belt now pulls the firing front through the mixture, so that the sinter cake is completely burnt out at the discharge of the belt. Due to the heat generated in the process, the fine ores melt superficially so that their grains form a firm connection. After breaking the sinter cake, it is cooled and classified. So-called grate and sintered material can remain in the sintering plant. The finished sinter is fed to the blast furnace.
- the sintered material produced by the process according to the invention is outstandingly suitable for use as a blast furnace feedstock.
- the invention further relates to a blast furnace feed which can be prepared by the process according to the invention.
- the premix contains 50 to 99 wt.%, Preferably 60 to 90 wt.%, In particular 70 to 85 wt.% Of metal and / or metal oxide-containing fines and 1 to 20 wt.%, Preferably 1 to 15% by weight, conventional additives and mineral binder.
- the mineral binder comprises 30 to 98% by weight lime-based material and 2 to 70% by weight, preferably 10 to 60% by weight, of mineral raw material.
- the premix contains from 0 to 30% by weight of additives, preferably coke breeze, pan breakout and / or slags.
- Another object of the invention is a premix for the production of the blast furnace feedstock according to the invention comprising a metal and / or metal oxide-containing fines and a mineral binder comprising a mineral raw material and a kalkstämmiges material, wherein as a mineral raw material a clay mineral-containing raw material is used, which is a silicon oxide Content of at least 40% by weight, and having a fines content of less than 4 ⁇ m of at least 20% by weight and a particle size fraction of less than 1 ⁇ m of at least 10% by weight.
- a clay mineral-containing raw material which is a silicon oxide Content of at least 40% by weight, and having a fines content of less than 4 ⁇ m of at least 20% by weight and a particle size fraction of less than 1 ⁇ m of at least 10% by weight.
- Mix 1, 2, 3, 3a, 3b there are five different Sinterbandmischungen (mix 1, 2, 3, 3a, 3b) produced.
- the mixed material 3a and 3b fine material, which has a defined proportion of intermediate grain sizes, mixed with the respective binder and conventional sintering aids and adjusted the mass moisture.
- a mineral raw material is used as a binder having a silica content of at least 40 wt.%, And a Feinstkornanteil of less than 4 microns of at least 20 wt.% And a particle size fraction of less than 1 micron of at least 10 % By weight.
- the mix 1, 2 and 3 is prepared without the addition of binder. Subsequently, the mix is mixed with water and layered on a sintered belt.
- the mix has a specific Gas sheströmiana, which can be measured by the pressure loss of a compressed air flow through the mixture. A low pressure loss indicates good gas flowability. A good Gas sheströmiana is desirable in the sintering process, since it leads to a good burn through of the sinter cake.
- the following table illustrates the pressure losses for the mix 1, 2, 3, 3a, 3b.
- a comparison of the mix 1, 2, 3 reveals that an increase in the proportion of inter-grain sizes leads to an increase in the pressure loss and to a reduction in Gas millströmhus.
- a comparison of the mixed material 3, 3a shows that improved gas flowability can be achieved by the addition of CaO as binder.
