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 |

20090090216 | PROCESS FOR PRODUCING MOLTEN IRON AND APPARATUS FOR PRODUCING MOLTEN IRON - A process for producing molten iron with a combination of a moving-hearth reducing furnace and an iron bath-type melting furnace includes a step of charging a bedding carbonaceous material having an average particle diameter of 1 to 5 mm on a hearth of the moving-hearth reducing furnace and placing carbonaceous material-containing agglomerates containing a powdery iron oxide source and a powdery carbonaceous reductant on the bedding carbonaceous material; a step of thermally reducing the carbonaceous material-containing agglomerates while moving the hearth in the moving-hearth reducing furnace to generate solid reduced iron and simultaneously thermally carbonizing the bedding carbonaceous material to generate char; a step of continuously charging the solid reduced iron and the char into the iron bath-type melting furnace from thereabove without substantial cooling; and | 04-09-2009 |
20100068088 | HOT BRIQUETTE IRON AND METHOD FOR PRODUCING THE SAME - Hot briquette iron includes a plurality of reduced iron particles which are bonded to each other by hot forming, wherein the reduced iron particles each have a surface region having an average carbon content of 0.1 to 2.5% by mass and a central region positioned inside the surface region and having an average carbon content higher than that of the surface region. | 03-18-2010 |
20100218420 | METHOD OF PRODUCING CARBONACEOUS MATERIAL-CONTAINING BRIQUETTES USING STEEL MILL DUST CONTAINING OIL - The present invention is directed to providing a production method capable of producing carbon composite briquettes having sufficient strength without excessively reducing a production capacity, even using steel mill dust containing oil. This method comprises: adding at least a carbonaceous material and a binder to steel mill dust containing oil and mixing them to form a powdery mixture; compacting the powdery mixture by means of a pressure roll to produce briquettes; and recognizing an increase/decrease in an oil content of the powdery mixture to adjust a rotation speed of the pressure roll so as to lower the rotation speed along with an increase in the oil content. | 09-02-2010 |

20080204067 | SYNCHRONOUS SEMICONDUCTOR DEVICE, AND INSPECTION SYSTEM AND METHOD FOR THE SAME - The present invention provides a synchronous semiconductor device suitable for improving the efficiency of application of electrical stresses to the device, an inspection system and an inspection method thereof in order to efficiently carrying out a burn-in stress test. A command latch circuit having an access command input will output a low-level pulse in synchronism with an external clock. The pulse will pass through a NAND gate of test mode sequence circuit and a common NAND gate to output a low-level internal precharge signal, which will reset a word line activating signal from the control circuit. Simultaneously, an internal precharge signal passing through the NAND gate will be delayed by an internal timer a predetermined period of time to output through the NAND gate a low-level internal active signal, which will set a word line activating signal from the control circuit. | 08-28-2008 |
