TH738A - A process for producing porous iron is by directly reducing the material containing iron oxide. - Google Patents

Abstract

The invention relates to the process of producing perforated iron by reducing (reducing) the iron oxide-containing matter directly. Consists of reducing in a basin designed to allow the substance to be inserted Move fluidly And the final reduction, which is done At temperatures below the melting point of the incinerator inserted In the recirculating furnace

Claims (1)

1. In the porous iron production process by directly reducing the material containing the iron oxide. Which includes reducing substances advance A page in a basin designed to allow the inserted substance to move as a flow and reduce the final substance acting at low temperature. Than the melting point of the substance in the furnace Improved circulation system, which consists of reducing the face of fine-grained objects that Contains iron oxide And assembled with steel in the basins designed to Move like Flow to obtain metal content 50 to 80% of the iron content. It is present in fine grains containing iron oxide and afterwards the deuxes of the granular material obtained by reducing it. 2. The process of claim 1, where the pre-reduction in Basins designed to allow the inserted substance to move like a fluid will have This results in metal content 60 to 70%. 3. The process of claim 1 or 2 is unique in that The final reduction in a recirculating furnace will also be effective. Method of using a solid carbon oxygen reducer 4. Treatment according to claim 3 where at least the reducer Most solid carbon oxygen used for The final reduction is applied to the designed basin. The inserted substance moves like a fluid And will be put into Circulating furnace in hot condition with the object 5. Process according to claim 1 where the particle size of the fine-grained material containing iron oxide is not approximately 2 mm. Fine grains containing iron oxide are less than 2 mm. 7. Process according to claim 1 where sulfur decomposes. The fine solids are put into the circulating kiln. 8. Process according to claim 7 where sulfur decomposition has Particle size less than 3 millimeters 9. Process according to claim 7 where the object released from The recirculating furnace is cooled. And then separated Porous iron Excess fuel And decomposition of sulfur 1 0. Process according to claim 3 where the reducing agent is charcoal 1 1. Process according to claim 7, where the number of decay The sulfur is between approximately 1 and approximately 5 percent by weight. Of the weight of the substances put into the furnace Circular system (11 claims, 2 pages, 1 picture)
