Abstract: PCT No. PCT/EP96/05446 Sec. 371 Date Dec. 21, 1998 Sec. 102(e) Date Dec. 21, 1998 PCT Filed Dec. 5, 1996 PCT Pub. No. WO97/21840 PCT Pub. Date Jun. 19, 1997The granular sponge iron is supplied to a roller press at temperatures of 600 to 850 DEG C. for molding the hot briquets. There is produced a strip structure of sponge iron containing formed hot briquets, which are arranged at a distance from each other. By smashing the strip structure, the hot briquets are separated from each other, so that fragments of the strip structure are obtained. The hot briquets and at least part of the fragments are cooled to temperatures in the range from 20 to 400 DEG C., and the cooled briquets and fragments are passed through a rotary drum. In the rotary drum, fine-grained fines of the briquets and fragments are produced. Subsequently, these fines are separated from the briquets and fragments, as they exhibit a pyrophoric behavior.

Abstract: Process for producing Iron carbide wherein, in a first stage, Iron ore is reduced to sponge iron using a reducing gas containing at least 90% hydrogen, on a nitrogen-free basis, to produce a sponge iron having a carbon content of less than 1% wt.; then in a second stage the sponge iron is fluidized at a temperature of 500 to 800° C. with a methane-containing fluidizing gas in a fluidized bed reactor wherein the water content of the gas in the reactor is not more than 1.5% wt., to produce a product wherein at least 85% of the iron content is in the form of Fe3C.

Abstract: So as to achieve the most thorough reduction and carburisation to produce Fe3C in a relatively short time and relatively economically, a two-stage treatment in fluidised beds is carried out. The first stage is carried out in a circulating fluidised bed system, the hourly circulation of solids being at least five times the weight of solid present in the fluidised bed reactor, and the greater part of the iron content of the charge being prereduced. The remaining reduction and the partial or complete conversion into Fe3C are carried out in the second stage in a classical fluidised bed. From the off-gas of the circulating fluidised bed, water is condensed, the gas is refreshed (replenished) by the addition of reducing gases and is heated to the temperature required for the process. A portion of the heated circulating gas is passed into the classical fluidised bed, as a fluidising gas, the other portion of the circulating gas being passed, as the fluidising gas, into the fluidised bed reactor of the circulating fluidised bed. The off-gas of the classical fluidised bed is passed, as the secondary gas, into the fluidised bed reactor of the circulating fluidised bed.

Abstract: A plant for the heat treatment of solids containing iron oxide includes a fluidized bed reactor. The reactor includes at least one gas supply tube at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is located, and a mixing chamber being located above the upper orifice region of the at least one gas supply tube. The gas flowing through the at least one gas supply tube entrains solids from the stationary annular fluidized bed-into the mixing chamber when passing through the upper orifice region of the at least one gas supply tube.

Abstract: A process of continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium. To ensure that the pressure between two regions can be reduced at low cost and with little maintenance effort when continuously conveying granular solids, a gaseous medium is injected into a tube through an upwardly directed nozzle at the point where the granular solids are conveyed through a descending line into an ascending line.
