| 20090008842 | METHOD AND APPARATUS FOR PRODUCING METALLIC ULTRAFINE PARTICLES - An object of the present invention is to efficiently produce ultrafine particles having such a small diameter as 50 nm or less, a narrow range of size distribution, and a non-oxidation surface. According to the present invention, the metallic ultrafine particles are produced by dropping a raw metallic powder onto a controllably heated evaporating surface in a decompressed inert gas; instantly evaporating the raw metallic powder to form the ultrafine particle; and condensing and depositing the ultrafine particle on a trapping surface arranged above the evaporating surface. The raw metallic powder is any one of a single metal, an alloy and an intermetallic compound, preferably has an average particle diameter controlled to 500 μm or smaller so that the powder can be instantly evaporated, and is preferably supplied by a minute amount. | 01-08-2009 |
| 20090166937 | DIRECT SMELTING PLANT - A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes an offgas duct assembly to facilitate flow of offgas from the vessel, the offgas duct assembly including two offgas ducts of matching diameter extending outwardly from the vessel. | 07-02-2009 |
| 20140210144 | COMPOSITE DEGASSING TUBE - Disclosed is a degassing tube formed, at least partially, of a composite material and configured to degas molten metal. The degassing tube may include a supply tube configured to deliver gas received from a supply source to an outlet of the degassing tube, and a diffuser body coupled to the supply tube and formed, at least partially, of a composite material. In some embodiments, a combination of the composite material and a phosphate bonded refractory material may be used to form respective sections of the diffuser body. The composite material may include layers of a woven fiber reinforcing fabric embedded within a ceramic matrix. In some embodiments, the phosphate bonded refractory material is a castable monolithic refractory which chemically bonds to the composite material. | 07-31-2014 |
