  • Publication number: 20110296952
    Abstract: A process by which molten solder is purified in-situ, making the soldering process more efficient and yielding better results, particularly for lead-free soldering. Lead-free solder becomes practical for use since the temperature for reliable soldering is reduced. A layer of active additive is maintained on the surface of molten solder for scavenging metal oxide from the solder and assimilating metal oxide into a liquid layer. The active additive is an organic liquid having nucleophilic and/or electrophilic groups. As an example, a layer of dimer acid maintained on a wave soldering apparatus scavenges metal oxide from the bath, and assimilates dross that may form on the surface. Scavenging metal oxide cleanses the bath and lowers viscosity of the solder, and PC boards or the like soldered on the wave have reliable solder joints.

    Abstract: An injector insert pipe is arranged in the gas channel of a nozzle for injecting oxygen-containing gas into a pig iron production unit, wherein an interspace which surrounds the pipe is present over the entire pipe length between the wall of the gas channel and the pipe outer wall . The pipe extends at least as far as the nozzle end face which contains the mouth of the gas channel. The pipe space is connected to an oxygen-containing gas feed line, and the interspace is connected to a protective gas supply line. In a process, oxygen-containing gas is fed into the pipe space, which after it has flowed through the pipe, enters the production unit at an entry velocity, and the interspace is simultaneously flowed through by a gas which exits into the production unit at an exit velocity, wherein the entry velocity is greater than the exit velocity.

  • Publication number: 20110277591
    Abstract: A process for the direct reduction of iron ore when the external source of reductants is one or both of coke oven gas (COG) and basic oxygen furnace gas (BOFG). Carbon dioxide (CO2) is removed from a mixture of shaft furnace off gas, obtained from a conventional direct reduction shaft furnace, and BOFG. This CO2 lean gas is mixed with clean COG, humidified, and heated in an indirect heater. Oxygen (O2) is injected into the heated reducing gas. This hot reducing gas flows to the direct reduction shaft furnace for use. The spent hot reducing gas exits the direct reduction shaft furnace as shaft furnace off gas, produces steam in a waste heat boiler, is cleaned in a cooler scrubber, and is compressed and recycled to join fresh BOFG. A portion of the shaft furnace off gas is sent to the heater burners. The BOFG and COG are also employed for a variety of other purposes in the process.

  • Publication number: 20110000338
    Abstract: A detection method for detecting a concavo-convex shape surface defect existing on a ferromagnetic metal object including sensing a signal attributed to strain of the concavo-convex shape surface defect having a size in a range of 0.5 to 6 ?m. The signal is magnetic flux leaking from the ferromagnetic metal to which magnetic flux is applied. A detecting apparatus incorporates a magnetizer for magnetizing a ferromagnetic metal and a plurality of magnetic sensors arranged in the direction perpendicular to a traveling direction of the ferromagnetic metal to sense a signal attributed to strain of a concavo-convex shape surface defect having a size in a range of 0.5 to 6 ?m.

  • Patent number: 7854784
    Abstract: A method for making solar grade silicon from metallurgical grade silicon is accomplished by treating a calcium silicate based slag with ferrosilicon in the first vessel so as to obtain a purification of the calcium silicate based slag. In a second vessel, the purified calcium based silicate slag is used to treat metallurgical grade silicon in order to obtain a solar grade silicon. The purification of calcium silicate based slag in the first vessel is accomplished to reduce phosphorous to a level of less than 3 ppmw.

  • Patent number: 7854909
    Abstract: A process for treating a finely particulate, in particular metal-containing, charge material: The charge material and a treatment gas, in particular a reduction gas, are introduced into a fluidized bed chamber of a fluidized bed reactor to form a fluidized bed. After at least partial reaction in the fluidized bed, the treatment gas is discharged from the fluidized bed and, outside the fluidized bed, is at least partially reprocessed, preferably oxidized, by an exothermic, chemical reaction with a reactant, preferably with a gaseous and/or liquid oxidizing agent. The thermal energy of this reaction is at least partially introduced into the fluidized bed chamber, in particular into the fluidized bed, or being discharged therefrom to affect the temperature of the particulate material above the bed. Also an apparatus for operating such a fluidized bed includes the chamber, lines into and out of the chamber for gas and material and a cyclone at the chamber for the material.

  • Publication number: 20100311847
    Abstract: A process and device is provided for the generation and purification of a crude gas for synthesis gas generation from a solid carbon-containing fuel by a coal gasification reaction. The fuel is mixed with a quenching medium directly after generation to dissipate the high internal energy and is then brought into contact with a solid basic alkaline earth metal compound or a sorbent consisting of a transition metal-containing compound just in the mixing chamber or downstream of the mixing chamber such that the acidic or basic or sulphur-containing or halogen-containing constituents contained in the crude gas and originating from the gasification reaction are absorbed. A solids-separating device downstream of the sorbent feed device removes the solid or solidified constituents from the system.

  • Publication number: 20100300247
    Abstract: 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.

  • Publication number: 20100288076
    Abstract: Device and method for separating metals and metal oxides thereof, in particular in non-ferrous alloys, such as zinc. To this end, zinc residues (dross) is placed in a rotary drum and heated. After a certain treatment time, pure metal located in the bottom part of the drum is poured out. The invention proposes that the drum be held rotatably on a drive mechanism arranged in the cover of the furnace. This facilitates handling of the drum, more particularly when placing it on its drive mandrel. As a result, it is possible to use larger drums, resulting in a larger capacity and a more efficient process.
