| 20090031859 | METHOD FOR PRODUCING METALLIC IRON - A hearth material is laid in the form of a layer on the hearth prior to supply of a mixture containing a carbonaceous reducing agent and iron oxides onto a hearth of a reduction melting furnace, thereby forming a renewable hearth capable of being renewed, and the metallic iron is produced while renewing a part or the whole of the renewable hearth, which has deteriorated during operation, with the hearth material. | 02-05-2009 |
| 20100037728 | METHOD FOR REDUCING CHROMIUM CONTAINING RAW MATERIAL - An object of the present invention is to provide a method for reducing a chromium-containing material at a high chromium reduction degree. In the method of the present invention, a mixture of a feedstock containing chromium oxide and a carbonaceous reductant is heated and reduced by radiation heating in a moving hearth furnace. The average rate of raising the temperature of the mixture in the reduction is preferably 13.96° C./s or higher in the period from the initiation of the radiation heating of the mixture until the mixture reaches 1,114° C. | 02-18-2010 |
| 20100300247 | METHOD FOR PRODUCING REDUCED METAL AND SLAG CONTAINING OXIDIZED NONFERROUS METAL USING AN UPGRADED COAL - The present invention provides a method for producing a high-quality reduced metal using an upgraded coal as a carbonaceous material to be incorporated. In the method, coal is first aged by heating in an organic solvent to produce upgraded coal for metallurgy having higher thermal plasticity than that of the coal. Then, a mixture of the upgraded coal for metallurgy and a metal oxide-containing raw material is agglomerated by an agglomerator, and the resultant agglomerates are reduced by heating in a furnace and then melted by further heating to produce a reduced melt. The reduced melt is cooled and solidified in the furnace to produce a reduced solid. The reduced solid is discharged to the outside of the furnace and slag is removed using a screen to recover a metal as a reduced metal. | 12-02-2010 |
| 20110024681 | TITANIUM OXIDE-CONTAINING AGGLOMERATE FOR PRODUCING GRANULAR METALLIC IRON - An object of this invention is to provide a titanium-containing agglomerate for producing granular metallic iron. The agglomerate is useful for obtaining a high yield of high-quality granular metallic iron in a size that is suitable for handling by using an iron source containing titanium oxide and other gangue components and heating at a relatively low temperature. The agglomerate contains: an iron source including titanium oxide of at least 5 mass % but less than 10 mass % in terms of TiO | 02-03-2011 |

| 20080216440 | JOINT CONSTRUCTION, FITTING AND MANUFACTURING PROCESS OF FITTING - Since an inside piece of a joint block is abutted to a rib of a second opposed piece under a pressure by engaging a first opposed piece of a frame member with the joint block, the inside piece can be securely abutted at the position of the rib even when the second opposed piece and the joint block are slightly deformed, which secures a predetermined joint intensity by preventing a variation of the abutment position. Since the joint block is abutted with the rib, the pressure per a dimension can be more increased than abutting with the whole surface of the inside piece, which consequently increases the frictional force to improve the joint intensity. | 09-11-2008 |
| 20090274815 | RICE MODIFIER, COOKED RICE FOOD USING THE RICE MODIFIER, AND THOSE PREPARATION PROCESSES - A rice modifier, containing a granular material sieved over 0.5 mm-opening (32-mesh) sieve at a content of 5% by weight or more and 100% by weight of less, having thermal solubility of equal to or higher than 20%, and containing starch at a content of equal to or larger than 40% by weight. | 11-05-2009 |
| 20100288666 | PACKAGE FOR PAPER SLIP STACK - There is provided a package for paper slip stack, which can steadily and stably store the paper slip stack bundled by a packaging sheet and being easily released from the packaging sheet after being contained in a paper holder. | 11-18-2010 |
