摘要： The present invention provides a reducing furnace of the rotary hearth-type and a method for reducing a metal oxide simplified in the process from dehydration to molding, according to which a moisture-rich powdery raw material is reduced at low cost. The present invention also provides an operation method whereby dusts or sludge generated in the refining or processing of metal are economically recycled. A powdery mixture having a moisture content of 100% or higher relative to the total mass of a metal oxide-containing powder and a carbon-containing powder is made into a slurry and mixed by stirring. Thereafter, the slurry is dehydrated to a moisture content of 16 to 26% and compression-molded into articles. The cylindrical or granular shaped articles having a thickness or diameter of 30 mm or less thus obtained are fed to a zone the atmospheric temperature of which is 1170 DEG C or lower in the furnace and reduced through calcination by a rotary hearth reducing furnace thereby to provide a metal.

摘要： A mixture comprising a metal oxide-containing powder and a carbon powder and water in an amount of 100 % or more relative to the total mass of both the powders is agitated for mixing to form a slurry. The slurry is dewatered so as to have a water content of 16 to 26 %, and the resultant product is subjected to compression molding to produce cylindrical or granular moldings having a thickness or diameter of 30 mm or less. The moldings are charged into a portion having an atmospheric temperature of 1170 DEG C of a reducing furnace of rotary hearth type, and thereafter is reduced in the furnace to produce a metal. The above method for operating a reducing furnace of rotary hearth type allows the simplification of the process from dewatering to molding and thus results in a process for reducing a metal oxide at a lower cost, and further can provide a method for economical recycling of the dust and sludge produced in a process of refining or working of a metal.

摘要： The present invention provides: a method for drying compacts containing water so as not to cause explosion and powdering; a method for reducing the compacts after being dried with great efficiency in a rotary-hearth-type reducing furnace; and a rotary-hearth-type metal reducing furnace. In the present invention, when compacts comprising powder containing metal oxide and carbon are dried, the critical value of a water evaporation rate, beyond which explosion occurs, is determined from the size and porosity of the compacts, then the water evaporation rate is controlled to a value not exceeding the critical value and, by so doing, the increase in the internal pressure of the compacts caused by the generation of water vapor is prevented. By the method, the explosion and cracking of the compacts are prevented. Further, when compacts are dried in a rotary-hearth-type reducing furnace, explosion is prevented by controlling the heat supply rate to the compacts through the above method and successively the compacts are incinerated and reduced in the same furnace.

摘要： A method for producing a reduced iron compact having a high crushing strength, hardly powdering, and having a high reducibility by using a baking reducing furnace of solid reducing type such as a rotary hearth reducing furnace, a reduced iron compact produced by the method, and a method for smelting-reducing the reduced iron compact in a blast furnace. In the method for producing the reduced iron compact, the compact is so produced that the atomic molar ratios of the carbon in a raw powder of a mixture of an iron oxide-containing powder and a carbon-containing powder and the oxygen chemically bonded to iron, manganese, nickel, zinc, and lead or the content of the ferric oxide in the raw powder is in a specific range and that the porosity is in a specific range, and the compact is placed on the hearth of a reducing furnace which the hearth rotates the compact, heated by the heat of the burning gas in the upper part of the furnace, and baked and reduced above a predetermined temperature.
