摘要： A process to improve electric arc furnace steelmaking. The efficiency increase is due to the metal-slag stirring that is produced by bottom gas injection through gas permeable ceramic elements. The permeable elements are not penetrated by the liquid metal, which does not stop the gas flow.The process is carried out in combination with a furnace charging door stopper device. The device avoids liquid ejections through the furnace charging door during the injection periods. The electric arc furnace steelmaking generalized practices are more effective when the molten metal is being stirred by gas injection, by increasing the metal-slag and the slag-atmosphere interphase area. When the stirring gas is natural gas, the process conditions, oxidizing or reducing, are reinforced according to the slag in the bath.

摘要： A mechanism and flow conduits for introducing and transporting a set of separated fluids and a stream of solid fines through passageway in a rotating metallurgical converter for introducing such fluids and solid fines into a liquid metal contained in the converter.Stationary conduits from flow sources connect to a non rotative sleeve which forms the external portion of a rotary joint able to introduce a set of separated fluids into the rotating converter passageways. Each separated stationary fluid conduit connects to port holes in the fixed sleeve to lead the flow to the interior of the sleeve, and connects a circumferential channel formed in rotating rings located between a rotating shaft affixed to the converter vessel trunnion pin and the static sleeve with a seal between each adjacent ring and corresponding channel. A port hole is located in each rotating channel ring for leading the fluid through internal flow paths inside and along the axis of the shaft body.The flows paths connect to a plurality of pipes contained inside the trunnion pin central bore, which, in turn, connect a set of port holes of a multi passageway elbow, which serves for leading the fluids and solid fines stream to the ring side end of the trunnion pin and changes the direction of the fluids and stream of solids by ninety degrees so as to direct such fluids to the botton pipe lines which finally end up in the converter bottom injection nozzles.

摘要： This invention relates to a device used in the selection between two fluids that are to be injected into a liquid metal contained in a metallurgical converter: an oxidizing gas and another gas conveying powdered carbonaceous material; both fluids arrive through different conduits to a selecting valve located at the bottom of a metallurgical converter just before a single conduit tuyere for leading one of the fluids to the liquid metal by means of the selective mechanism in such valve. The valve design and operation avoids the possibility of mixing the oxidizing gas with the carbonaceous powder in any part of their path up to the metal bath by providing separate passages for each fluid and one inert gas purge passageway between said passages, and further including a safety mechanism which provides control means for the fluid to be correctly injected by avoiding the transport of the oxidizing gas or the carbonaceous material if the corresponding movable passage within the valve body is not correctly and precisely positioned.

摘要： A generally hollow cylindrical piston liner for insertion in an internal combustion engine between a piston and an engine block has a cast aluminum piston liner body with cast iron engine block contact surface structure extending therefrom and securely thermally bonded thereto for exhibiting a roughened outer contact surface adapted to interface with an engine block, and its method of manfacture. The cast iron contact surface member roughened surface is generated by introducing in a first mold step a mold wash substance that generates a substantially uniform bubble pattern within a mold wash matrix layer into which the molten iron is poured to thereby produce a roughened iron interface surface. The aluminum piston liner is then bonded to the iron liner in a second molding step by pouring molten aluminum into a pre-heated mold to bond the cast iron engine block surface structure to the aluminum liner. During the solidification stages, the molds are centrifugally rotated about the piston liner cylinder axis to established the required manufacturing precision required for large diameter piston liners. The piston liners typically form a series of circumferal motor block contact ribs spaced proportionately along the liner length to extend from a cylindrical body for carrying the cast iron contact surface structure.

摘要： Dross formation in the aluminum melting and/or refining is avoided partially or totally by the method of this invention. The method is useful in unmodified open top furnaces. The elimination or reduction of dross formation is carried out throughout the body of molten aluminum by the installation of gas injection devices to extend through the refractory lining in the bottom of the furnace. For longer life without clogging metal cased refractories of the directional porosity type are used for gas injection. Mixtures of inert and hydrocarbon gases are used with respective proportions chosen to match the design parameters of different types of furnaces. In operation the dross is eliminated by reactions of the injected gases with the impurities of the molten aluminum batch at its hottest temperatures in the body of the aluminum mass to thereby reduce dross generally caused by oxidation of the molten aluminum within the molten mass. Furthermore the injected gases at a multiplicity of injection sites permeate the entire molten batch to eliminate dross formation accelerated by the high temperature of the molten aluminum. By continuous flow of the injected gases, the surface of the aluminum melt is dynamically kept free of oxygen that might form dross there without the necessity of using a closed top furnace with an atmosphere control system.

摘要： The present invention relates to a new steelmaking process and apparatus which operates on an intermittent basis where several cycles composed of reducing and oxidizing periods are performed to create sufficient energy for melting of solid metallic charge, i.e., sponge iron, scrap, iron ore. During the reducing period, oxygen and carbonaceous material are injected through the vessel bottom thus attaining both carburization of a steam of the melt and generation of CO+H.sub.2 rich gas, and when the dissolved carbon of the melt is in the range of 3%-4%, conditions are then changed to the oxidizing period where solid metallic charge is added initially while oxygen injection is maintained, and until the solid charge has been melted, thus generating a stream of CO+CO.sub.2 gas rich in CO. In addition, other fluids and solids participate in the process, i.e., nitrogen, hydrocarbons, fluxes, and are used according to the appropriate period of the process. After several cycles have been performed, molten metal, preferably raw steel, is transferred to a ladle for further processing and an ignition molten metal heel remains in the vessel for initiation of the next heat.
