    Abstract: An iron making process and apparatus are disclosed. The process includes a direct reduction step of passing a reducing gas through a bed of (a) an iron-containing material, such as tabular lump ore, and (b) a bed forming material and producing a reduced iron material. The bed forming material is a material that facilitates forming the bed so that there is optimum upward flow of a reducing gas through the bed. The process also includes separating the reduced iron material and the bed forming material. The bed forming material may be re-used in the direct reduction step.

    Abstract: A process and an apparatus for producing metals from a metalliferous feed material are disclosed. The process includes the steps of partially reducing and at least partially melting a metalliferous feed material in a pre-reduction/melting means and completely reducing the partially reduced feed material in a reduction means. The pre-reduction/melting means is positioned directly above the reduction means and communicates with the reduction means so that at least partially molten, partially reduced feed material flows downwardly into a central region of the reduction means. The reduction means includes a vessel that contains a molten bath having a metal layer and a slag layer on the metal layer. The process includes injecting oxygen-containing gas into the reduction means and post-combusting reaction gas generated in the molten bath and injecting oxygen-containing gas into the pre-reduction/melting means and post-combusting reaction gas discharged from the reduction means. The process further includes injecting solid carbonaceous material and a carrier gas into a metal rich region of the molten bath and causing upward movement of splashes, droplets and streams of molten material which forms a transition zone.

    Abstract: A direct reduction process producing DRI from iron oxide particles by reduction at a about 750 °C with a reducing gas mainly H 2 and CO, that also includes CO 2 , H 2 0, and methane, a the reduction reactor and the top gas effluent from the reduction reaction after cooling/scrubbing is split. The resulting first top gas portion with a first hydrocarbon-containing make-up gas passes through a catalytic reformer yielding an improved hot reducing gas first effluent. The second top gas portion passes through a CO2 removal unit and then with the second hydrocarbon-containing make-up gas passes through a heater yielding a hot CO 2 -lean recycle reducing gas second effluent. The first and second effluents are fed to the reducing zone of the reduction reactor as the reducing gas reactant. The flow rate of at least the second of the two make-up gases is regulated to control the carbon content of the DRI produced.

    Abstract: マイクロ波精錬炉は、縦型炉体の上部に原料の供給口があり、炉底部に上下動可能の炉床部材が設けられている。炉底部の周囲には、縦型炉体の内部と連通するマイクロ波照射室が設けられている。マイクロ波照射室の内面はマイクロ波を反射する銅又は銅合金等により構成されている。縦型炉体の下部の側部と、炉床部材との間の間隙から、原料がマイクロ波照射室内に導入され、マイクロ波照射室内で原料は高効率にかつ集中的にマイクロ波MWを照射される。これにより、加熱された原料は、鉄鉱石が炭素源により還元されて溶融銑鉄が生成し、取出口から溶融銑鉄が取り出される。これにより、高炉製銑法に代わり、高エネルギ効率で溶融銑鉄を製造することができ、また所謂都市鉱山から貴金属等を回収することができる。

    Abstract: The present invention relates generally to a method and system for the supply of a continuous stream of hot direct reduced iron (HDRI) from a direct reduction (DR) shaft furnace or direct reduced iron (DRI) reheating furnace to a point outside of the DR shaft furnace or DRI reheating furnace where the HDRI stream is split into at least two HDRI streams. The first HDRI stream is sent continuously to a hot briquetting plant by gravity in a closed duct system. The second HDRI stream is sent continuously to an adjacent melting furnace also by gravity in a closed duct system, with a surge bin and feeders, or by a combination of gravity in a closed duct system, also with a surge bin and feeders, and a generally horizontal charge conveyor. Optionally, a third HDRI stream is employed to continuously feed multiple hot transport vessels.
