| 20110204103 | TUNDISH NOZZLE EXCHANGING DEVICE, AND TUNDISH NOZZLE FOR USE IN THE DEVICE - A tundish nozzle exchanging device and a tundish nozzle for use in the device, reducing a distance between holes of the tundish nozzles, juxtaposed at a bottom of a tundish, compared to the conventional model. | 08-25-2011 |
| 20110101041 | SLIDING NOZZLE DEVICE - A sliding nozzle device automatically performs a series of operations of loading and unloading pressure between plates and opening and closing a slide frame; maintaining the pressure without additional operations; and operates at full stroke during molten steel flow control. An auxiliary plate-exchanging mechanism includes slide axes moving in the same direction as a hydraulic cylinder operates, and an arm having a proximal end placed around the slide axis. The plate-exchanging mechanism is fixed on an upside frame. A first engagement pin mounted on the proximal end of the arm is inserted in a first engagement groove in a first engagement member engaging with the slide axis, and second engagement pins mounted on bearings are inserted in second engagement grooves in the slide axes. With movement of the slide axes the engagement pins respectively move in the engagement grooves, thereby rotating the slide axes and the arm. | 05-05-2011 |
| 20110062193 | METHOD OF CONTROLLING SLIDING NOZZLE DEVICE AND PLATE USED THEREFOR - A method of controlling a sliding nozzle device | 03-17-2011 |
| 20090242592 | IMMERSION NOZZLE FOR CONTINUOUS CASTING - An immersion nozzle for continuous casting including a tubular body, the tubular body having at the upper end an inlet from which molten steel is introduced into a passage extending from the inlet downward inside the tubular body, the tubular body having a bottom and being depressed in cross section at least at a lower section, the lower section having two narrow sidewalls and two broad sidewalls, the narrow sidewalls having a pair of opposing first outlets communicating with the passage, the bottom having a pair of second outlets communicating with the passage. The lower section has ridges projecting into the passage respectively from the inner surfaces of the broad sidewalls between the pair of first outlets. The second outlets are arranged symmetrically about the axis of the tubular body such that the axes of the second outlets cross each other within the passage. | 10-01-2009 |
| 20090242163 | IMMERSION NOZZLE FOR CONTINUOUS CASTING - An immersion nozzle for continuous casting, including (1) a tubular body with a bottom, the tubular body having an inlet for entry of molten steel disposed at an upper end and a passage extending inside the tubular body downward from the inlet, and (2) a pair of opposing outlets disposed in a sidewall at a lower section of the tubular body so as to communicate with the passage, the nozzle comprising: a pair of opposing ridges horizontally projecting into the passage from an inner wall between the pair of outlets, the inner wall defining the passage. | 10-01-2009 |
| 20090233081 | ZIRCONIA-CARBON-CONTAINING REFRACTORY AND METHOD FOR PRODUCING SAME - A zirconia-carbon-containing refractory includes aggregate grains, a carbon bond formed between the aggregate grains, 80% by mass or more of a ZrO | 09-17-2009 |
| 20090145359 | Gas Shower Plate for Palsma Processing Apparatus - In a plasma processing apparatus for generating a plasma in a plasma generation space between a lower electrode and an upper electrode so that a processing object mounted on the lower electrode is subjected to plasma processing, a plurality of cutout portions for absorption of strain caused by thermal expansion due to rapid temperature increases in the plasma processing are formed at an equal pitch in an outer edge portion of a gas shower plate included in the upper electrode. Thus, the gas shower plate can be prevented from being damaged by occurrence of cracks in the outer edge portion of the gas shower plate or the like. | 06-11-2009 |
| 20090075808 | Refractory, Method for Manufacturing Refractory, and Refractory Raw Material - A carbon-containing refractory is provided, which can improve the thermal shock resistance, the abrasion resistance, and the corrosion resistance without degrading the oxidation resistance. | 03-19-2009 |
