20120152061 | METHOD AND SYSTEM FOR PRODUCING DIRECT REDUCED IRON AND/OR HOT METAL USING BROWN COAL - The present invention provides a method for producing direct reduced iron and/or hot metal using high-moisture content carbonaceous material, including: agglomerating carbonaceous material from the high-moisture content carbonaceous material with a metal oxide-bearing material to form an agglomerate suitable for use in a direct reduction and/or hot metal producing process. The method also includes distilling the high-moisture content carbonaceous material. The method further includes dry quenching the carbonaceous material obtained from the distilling step. The method still further includes drying the high-moisture content carbonaceous material with energy from a hot off gas from a furnace for producing direct reduced iron and/or hot metal prior to the distilling step. | 06-21-2012 |
20120297925 | ELECTRIC FURNACE FOR PRODUCING MOLTEN METAL HAVING MATERIAL RECYCLING CAPABILITY - The present invention relates generally to a smelting operation or the like, by which molten metal is produced from a metal oxide after metal oxide agglomerates are directly reduced and melted with a carbonaceous material in an electric heating and melting furnace. More specifically, the present invention relates to an electric furnace for producing molten metal that has material recycling capability, especially in-process material recycling capability. | 11-29-2012 |

20090136887 | ROTARY HEARTH FURNACE - PROBLEM TO BE SOLVED: To provide a rotary hearth furnace which has a simple furnace structure in which the furnace is not damaged even if the furnace is operated for a long term while presenting general equations capable of adequately determining a thermal expansion margin in the rotary hearth furnace. | 05-28-2009 |
20090145725 | SCREW CONVEYOR AND OPERATION CONTROL METHOD FOR THE SAME - A screw conveyor for conveying an object to be conveyed, supported by a casing | 06-11-2009 |
20090160107 | Rotary Hearth Furnace And Method Of Operating The Same - A rotary hearth furnace includes an exhaust gas eductor. The exhaust gas eductor includes a compartment-defining portion and an exhaust duct. The compartment-defining portion is provided on part of a ceiling of the rotary hearth furnace in an exhaust gas discharge region, and an exhaust duct is connected to the compartment-defining portion. The lower surface of the compartment-defining portion lies higher than the lower surface of the other portion of the ceiling. The compartment-defining portion defines a compartment where the exhaust gas stays. The exhaust duct can include a cooling medium injection nozzle. The furnace increases fuel efficiency by completely burning combustible components remaining in exhaust gas generated in the rotary hearth furnace so as to use the combustible components efficiently for the heating and reduction reaction in the rotary hearth furnace, without problems in producing reduced iron. | 06-25-2009 |
20110107874 | METHOD FOR PRODUCING BRIQUETTE, METHOD FOR PRODUCING REDUCED METAL, AND METHOD FOR SEPARATING ZINC OR LEAD - An object of the present invention is to produce briquettes that have high strength even when the amounts of binder and water used are decreased as much as possible. A method for producing briquettes that achieve this object includes a step of forming primary granules by using a powder containing a metal oxide and at least one of zinc oxide, lead oxide, and titanium oxide and a step of compressing the primary granules still containing the at least one of zinc oxide, lead oxide, and titanium oxide so as to mold the primary granules into secondary granules. | 05-12-2011 |
